Opinion
The defendant, Troy Artis, appeals from the judgment of conviction, rendered after a jury trial, of accessory to assault in the first degree by means of a dangerous instrument in violation of General Statutes §§ 53a-8 and 53a-59 (a) (1). On appeal, the defendant claims that the trial court (1) improperly denied his postverdict motion for a judgment of acquittal on the ground of insufficient evidence and (2) abused its discretion by denying his motion to suppress.1 We reverse the judgment of the trial court.
Based on the correctly and incorrectly admitted evidence, the jury reasonably could have found the following facts. At approximately 11 p.m. on February 14, 2008, the victim, Alexis Otero, drove some of his friends to Club Blu on Ann Street in Hartford where he was sometimes employed as a bouncer. Approximately half *571an hour later, Otero walked two blocks from Club Blu to Club NV near the comer of Allyn and High Streets.
On the same evening, Christina Miaño also went to Club NV together with her then boyfriend, Robert Acevedo,2 and his sister, Anna Acevedo, and Anna’s boyfriend, the defendant. Robert Acevedo drove the four of them to Hartford in his silver Infiniti automobile. At approximately 11 p.m., as the four walked toward Club NV, the defendant, who carried a knife on his belt, asked Robert Acevedo for the keys to the Infiniti so he could put his knife in the automobile before undergoing a security check at Club NV. Miaño and Anna Acevedo went on ahead to Club NV, where they socialized apart from the defendant and Robert Acevedo.
Near closing time, Otero, who knew Miaño, visited with her for several minutes. At the time, he did not know that Miaño had arrived with Robert Acevedo, whom he did not know. Otero routinely photographed people at nightclubs for a radio station website, and that night he took a photograph of Miaño and Anna Acevedo.3
At closing time, Otero left Club NV to return to Club Blu. Miaño left Club NV at approximately the same time and got into the Infiniti with Robert Acevedo and Anna Acevedo. She sat in the front seat next to Robert Acevedo as the three, uncertain of the defendant’s whereabouts, waited for him to join them. Miaño saw Otero and beckoned for him to come speak with her, which he did. Once the conversation was over, as Otero crossed High Street on his way to Club Blu, Robert Acevedo drove the Infiniti straight toward him. Otero jumped onto the sidewalk and yelled an obscenity at *572Robert Acevedo, who apologized. According to Miaño, Robert Acevedo thought that Otero had “disrespected]” him by talking with her.
Shortly thereafter, the defendant opened the rear passenger door of the Infmiti from the outside, entered the automobile briefly and quickly exited to confront Otero. The defendant and Otero exchanged profanities, and the defendant then punched Otero in the face and shoulder as the two men engaged in a face-to-face flstfight that lasted somewhere between two and ten seconds. Seconds after the flstfight commenced, Robert Acevedo and Anna Acevedo got out of the Infiniti and approached the defendant and Otero. Otero was then struck from behind, causing him to fall to the sidewalk. While he was on the sidewalk, Otero was on all fours covering his head. For approximately ten to twenty seconds, he felt three or four people assault him from different directions. Miaño got out of the automobile when she saw Robert Acevedo, Anna Acevedo and the defendant all crowded around Otero while he was on the ground; Miaño was unsure as to what they were doing. Miaño then “grabbed Anna off’ Otero, and the two women began to argue. During the assault on Otero, Miaño did not see a weapon or a knife. At some point, she dropped her cell phone.
As Hector Robles, a Hartford police officer, walked toward the group of people surrounding Otero, others on the street called out, “cops . . . .” The fight broke up and the crowd dispersed.4 The defendant, Miaño, Robert Acevedo and Anna Acevedo got into the Infiniti and drove away. Anna Acevedo continued to express displeasure with Miaño and wanted to fight her.5 Robert *573Acevedo instructed the two women to stop, and he took Miaño to her mother’s home in order to separate the two women. According to Miaño, while they were driving from the scene, Anna Acevedo asked the defendant, “where’d that blood come from?” Miaño stated that she never looked at the defendant again after he got back into the automobile.6 Later, another police officer found blood splattered on the sidewalk.
When Otero got up from the sidewalk, the Infiniti was gone. He saw a cell phone and put it in his pocket. He also saw that his hand was bleeding heavily. He walked to Club Blu where he knew he would find a police officer and familiar people to help him. Jessie Rego, who was working at the door of Club Blu, observed that the cut in Otero’s thumb was so deep that he could see the bone. Rego also saw blood coming from Otero’s stomach. A police officer found a trail of blood between Club NV and Club Blu.
Otero was transported by ambulance to Hartford Hospital (hospital). Although Otero has no recollection of being transported to or arriving at the hospital, he remembers going into an operating room, where he was treated for seven puncture wounds to his torso, arms and hand. Twenty sutures and fifty staples were required to close Otero’s wounds. As a result of his injuries, Otero is no longer able to exercise as he once did, and walking is difficult due to an injury he sustained to his knee.
Although Otero has no recollection of talking to a police officer at the hospital, he was, in fact, interviewed by Sergeant Jeff Rousseau soon after arriving at the hospital. Rousseau testified that Otero told him that his *574assailants, two men and a woman, were in a newer gray Infiniti. He described both men as light-skinned black males, approximately twenty-seven to twenty-eight years old. The stockier of the two men had freckles on his face. According to Rousseau, Otero was not sure that he could identify the perpetrators, but he did not rule out identification. Otero gave Rousseau Miano’s cell phone.
The defendant was arrested pursuant to a warrant7 and subsequently was charged with assault in the first degree while aided by two or more persons in violation of General Statutes § 53a-59 (a) (4), conspiracy to commit assault in the first degree while aided by two or more persons in violation of General Statutes §§ 53a-48 and 53a-59 (a) (4), accessory to assault in the first degree in violation of §§ 53a-8 and 53a-59 (a) (1), and conspiracy to commit assault in the first degree with a dangerous instrument in violation of §§ 53a-48 and 53a-59 (a) (1).
During trial, the defendant filed a motion to suppress Otero’s out-of-court identification and to prevent any in-court identifications on the basis of his claim that the out-of-court identification was unnecessarily suggestive, and that any subsequent in-court identification would be tainted by the improper out-of-court identification and would thus lack an independent basis. During trial, after an evidentiary hearing outside the *575presence of the jury, the court denied the defendant’s motion in this regard, finding that although the initial identification was unnecessarily suggestive, it and the subsequent in-court identifications were reliable. At the close of the evidence, the court granted the defendant’s motion for a judgment of acquittal as to the charge of assault in the first degree while aided by two or more persons. The jury found the defendant guilty of accessory to assault in the first degree by means of a dangerous instrument and not guilty of the two conspiracy charges. The court thereafter sentenced the defendant to nine years incarceration, to run concurrent with the time remaining on a preexisting sentence, followed by eight years of special parole. The defendant appealed from the judgment of conviction. Additional facts will be set forth as necessary.
I
The defendant’s first claim is that the court improperly denied his motion for a judgment of acquittal after the verdict, as there was insufficient evidence that he intended to cause Otero serious.physical injury or knew that anyone involved in the altercation was armed with, or used, a deadly weapon or dangerous instrument.8 We disagree.
Count two of the amended substitute information alleges, in relevant part, that the state accuses the defendant “of accessory to assault in the first degree, and charges that on or about February 15, 2008 . . . [the defendant] with intent to cause serious physical injury to another person by means of a dangerous instrument, did intentionally aid another who caused such injury to such person ... in violation of Sections 53a-8 and 53a-59 (a) (1) . . . .”9 Following the presentation of *576evidence, the defendant orally moved for a judgment of acquittal as to all counts. The court denied the motion as to count two, among others, and the jury found the defendant guilty of accessory to assault in the first degree by means of a dangerous instrument. Subsequently, on November 2, 2009, the defendant filed a motion for a judgment of acquittal, which the court denied on January 7, 2010.
In denying the defendant’s postverdict motion for a judgment of acquittal, the court stated: “On the basis of all the evidence presented at trial and the logical inferences that can be drawn therefrom, it is my assessment that the jury reasonably could and did conclude that all of the elements of accessory to assault in the first degree as alleged10 were proven beyond a reasonable doubt. . . . The defendant was the first out of the car. A one-on-one fistfight ensued, lasting a matter of seconds, which [Otero] was winning. [Robert Acevedo and Anna Acevedo] jumped out of the car, one of the two striking [Otero] from behind and knocking him down on the sidewalk. Up to that point, [Otero] had not been stabbed.
“There was no interlude between the face-to-face fistfight and [Otero] being knocked to the ground from behind. And immediately while on the ground covering up, he was kicked, punched, struck from all angles by three people. [Miaño] was not involved in the assault *577of [Otero]. That left [Robert Acevedo and Anna Acevedo] and the defendant as the three persons assaulting [Otero] as he was down on the ground. The on-the-ground portion of this incident lasted a matter of seconds. When it was over, [Otero] had been stabbed seven times while on all fours covering up and while being beaten, hit and assaulted by three persons, one of whom was the defendant. All four, the defendant included, left the scene together in the Infmiti when the police arrived or [when] they were approaching. Additionally, there was evidence that earlier in the evening the defendant had a knife, which was placed back in the car in order to gain entry into [Club NV]. And the jury heard evidence of the observation in the car . . . they drove from the scene.
“In my view, that evidence in its entirety, if believed, and the reasonable inferences that can be drawn therefrom, support the conclusion of applying a beyond a reasonable doubt standard that the defendant intended to cause serious physical injury. And given the close contact while [Otero] was on the ground . . . that he knew one of the three had and was using an implement capable of causing serious physical injury. Seven stab wounds inflicted within an incident of a very short duration with all three closely huddled around the on-the-ground victim, pummeling him, supports a reasonable inference regarding the awareness that multiple stab wounds were being inflicted, as well as an intent to cause serious physical injury.
“With reference to the element, ‘intentionally aid,’ evidence of repeated intentional striking, kicking, et cetera, of the on-the-ground victim over a matter of seconds, during which time [Otero] was being stabbed seven times, and thereby keeping him down and inhibiting or preventing him from resisting or defending himself, amounts, in my view, to intentionally aiding the one of the three who was doing the stabbing, that is, *578the one committing the assault in the first degree with a dangerous instrument.” On the basis of our review of the evidence and the law, we conclude that the trial court properly denied the defendant’s postverdict motion for a judgment of acquittal.
We employ a two part test when reviewing claims of insufficient evidence. “First, we construe the evidence in the fight most favorable to sustaining the verdict. Second, we determine whether upon the facts so construed and the inferences reasonably drawn therefrom the [jury] reasonably could have concluded that the cumulative force of the evidence established guilt beyond a reasonable doubt. ... In evaluating evidence, the [finder] of fact is not required to accept as dispositive those inferences that are consistent with the defendant’s innocence. . . . The [jury] may draw whatever inferences from the evidence or facts established by the evidence it deems to be reasonable and logical. ... On appeal, we do not ask whether there is a reasonable view of the evidence that would support a reasonable hypothesis of innocence. We ask, instead, whether there is a reasonable view of the evidence that supports the [jury’s] verdict of guilty.” (Citation omitted; internal quotation marks omitted.) State v. Arthurs, 121 Conn. App. 520, 524, 997 A.2d 568 (2010).
“[P]roof beyond a reasonable doubt does not mean proof beyond all possible doubt . . . nor does proof beyond a reasonable doubt require acceptance of every hypothesis of innocence posed by the defendant that, had it been found credible by the [jury], would have resulted in an acquittal.” (Citations omitted; internal quotation marks omitted.) State v. Torres, 242 Conn. 485, 490, 698 A.2d 898 (1997). Although the jury may draw reasonable and logical inferences from the facts proven, it “may not resort to speculation and conjecture.” (Internal quotation marks omitted.) State v. Giguere, 184 Conn. 400, 403, 439 A.2d 1040 (1981).
*579The jury “must find every element proven beyond a reasonable doubt in order to find the defendant guilty of the charged offense, [but] each of the basic and inferred facts underlying those conclusions need not be proved beyond a reasonable doubt. ... If it is reasonable and logical ... to conclude that a basic fact or an inferred fact is true, the [jury] is permitted to consider the fact proven and may consider it in combination with other proven facts in determining whether the cumulative effect of all the evidence proves the defendant guilty of all the elements of the crime charged beyond a reasonable doubt. . . . Moreover, it does not diminish the probative force of the evidence that it consists, in whole or in part, of evidence that is circumstantial rather than direct. ... It is not one fact, but the cumulative impact of a multitude of facts which establishes guilt in a case involving substantial circumstantial evidence. . . . Questions of whether to believe or to disbelieve a competent witness are beyond our review. As a reviewing court, we may not retry the case or pass on the credibility of witnesses.” (Citations omitted; internal quotation marks omitted.) State v. Liborio A., 93 Conn. App. 279, 283-84, 889 A.2d 821 (2006). Furthermore, “our review requires us to consider all of the evidence presented at trial, irrespective of any alleged impropriety . . . . [T]o evaluate the sufficiency of the evidence presented, we assess all the evidence admitted at trial.” State v. Coyne, 118 Conn. App. 818, 826, 985 A.2d 1091 (2010).
The defendant in this matter was charged as an accessory to assault in the first degree by means of a dangerous instrument. For the purpose of determining criminal liability as an accessory, it is of no consequence whether one is labeled an accessory or a principal. State v. Barley, 35 Conn. App. 138, 142, 644 A.2d 386, cert. denied, 231 Conn. 913, 648 A.2d 157 (1994). “[T]o establish a person’s culpability as an accessory to a particular *580offense, the state must prove that the accessory, like the principal, had committed each and every element of the offense.” State v. Patterson, 276 Conn. 452, 483, 886 A.2d 777 (2005).
“To warrant a conviction for assault in the first degree in violation of § 53a-59 (a) (1), the state bore the burden of proving the following elements beyond a reasonable doubt: (1) the defendant possessed the intent to cause serious physical injury to another person; (2) the defendant caused serious physical injury to such person . . . and (3) the defendant caused such injury by means of a deadly weapon or a dangerous instrument.” State v. Holmes, 75 Conn. App. 721, 740, 817 A.2d 689, cert. denied, 264 Conn. 903, 823 A.2d 1222 (2003). “[A] conviction under § 53a-8 requires [the state to prove the defendant’s] dual intent . . . [first] that the accessory have the intent to aid the principal and [second] that in so aiding he intend to commit the offense with which he is charged. . . . Additionally, one must knowingly and wilfully assist the perpetrator in the acts which prepare for, facilitate or consummate it.” (Citation omitted; internal quotation marks omitted.) State v. Heinemann, 282 Conn. 281, 313, 920 A.2d 278 (2007).
“Intent is generally proven by circumstantial evidence because direct evidence of the accused’s state of mind is rarely available. . . . Therefore, intent is often inferred from conduct . . . and from the cumulative effect of the circumstantial evidence and the rational inferences drawn therefrom. ... It is axiomatic that a factfinder may infer an intent to cause serious physical injury from circumstantial evidence such as the type of weapon used, the manner in which it was used, the type of wound inflicted and the events leading up to and immediately following the incident.” (Internal quotation marks omitted.) State v. Vasquez, 68 Conn. App. 194, 207, 792 A.2d 856 (2002). Here, the jury reasonably could have inferred that the defendant intended *581to aid the principal to inflict serious physical injury to Otero and that the principal used a dangerous instrument.
The defendant claims that it was impermissible speculation for the court to conclude that “[s]even stab wounds inflicted within an incident of a very short duration with all three [people who had attacked Otero] closely huddled around the on-the-ground victim, pummeling him, supports a reasonable inference regarding the awareness that multiple stab wounds were being inflicted, as well as an intent to cause serious physical injury.” He also argues that “the small, quiet nature of a knife blow, the brevity of the incident, the dim lighting, and the inherent stress and chaos of the fight all make it virtually impossible for [the defendant] to have noticed whether [Robert Acevedo or Anna Acevedo] was using a knife . . . ,”11 We disagree.
The evidence admitted at trial was adequate to permit the jury to conclude that the defendant was present when either Robert Acevedo or Anna Acevedo caused Otero to fall to the sidewalk and, in concert with the two of them, surrounded Otero, whom they struck, kicked and pummeled as he protected his head. The jury was not required to, but reasonably could have, inferred that the defendant intended to aid the principal in causing Otero serious physical injury.
Serious physical injury “means physical injury which creates a substantial risk of death, or which causes *582serious disfigurement, serious impairment of health or serious loss or impairment of the function of any bodily organ. . . . .” General Statutes § 53a-3 (4). In this matter, the jury heard evidence that Otero sustained a laceration to his thumb that revealed the bone and seven stab wounds that required twenty stitches and fifty staples to close. Otero was hospitalized for several days, required additional surgery and had not fully recovered as of the time of trial. “[I]t is the right and the duty of the [trier of fact] to draw reasonable and logical inferences crom the evidence. ... In considering the evidence introduced in a case, [triers of fact] are not required to leave common sense at the courtroom door . . . nor are they expected to lay aside matters of common knowledge or their own observations and experience of the affairs of life, but, on the contrary, to apply them to the facts in hand, to the end that their action may be intelligent and their conclusions correct.” (Internal quotation marks omitted.) State v. Barnett, 53 Conn. App. 581, 592-93, 734 A.2d 991, cert. denied, 250 Conn. 918, 738 A.2d 659 (1999).
“A dangerous instrument means any instrument, article or substance which, under the circumstances in which it is used or attempted or threatened to be used, is capable of causing death or serious physical injury .... [A] dangerous instrument may be an ordinary object not designed to cause death or serious physical injury . . . [and each] case must be individually examined to determine whether, under the circumstances in which the object is used or threatened to be used, it has the potential for causing serious physical injury.” (Citation omitted; emphasis in original; internal quotation marks omitted.) Id., 590.
In the present case, the jury heard evidence that prior to entering Club NV, the defendant left a knife in the Infiniti. After leaving Club NV, Robert Acevedo attempted to run over Otero with his automobile *583because he had spoken with Miaño, Robert Acevedo’s date for the evening. Thereafter, the defendant briefly entered the Infiniti before confronting Otero and initiating a fistfight with him. Robert Acevedo and Anna Acevedo then got out of the Infiniti and, shortly after, Otero was hit from behind, causing him to fall to the sidewalk. When the defendant and Robert Acevedo and Anna Acevedo became aware of the police presence, they got into the Infiniti and drove away. As a result of the altercation, Otero suffered a deep cut to his thumb and seven stab wounds to his torso and arms that required surgical intervention. Otero was unable to walk and exercise as he once had. On the basis of this evidence, the jury reasonably could have inferred, beyond a reasonable doubt, that the defendant participated in an assault upon Otero and, given the nature of Otero’s wounds, that the defendant intended to cause Otero serious physical injury. See State v. Hines, 89 Conn. App. 440, 449-50, 873 A.2d 1042, cert. denied, 275 Conn. 904, 882 A.2d 678 (2005); State v. Holmes, supra, 75 Conn. App. 742 (intent inferred from conduct and cumulative effect of circumstantial evidence).
The defendant also claims that there was no evidence that he knew that a knife was used in the assault on Otero. The crime of which the defendant was found guilty does not require that he knew of the presence of a knife, if indeed, that is the instrument that caused Otero’s injuries. See General Statutes § 53a-8 (a).
Our Supreme Court has held that “to establish acces-sorial liability under § 53a-8 for manslaughter in the first degree with a firearm . . . the state must prove that the defendant, acting with the intent to cause serious physical injury to another person, intentionally aided a principal offender in causing the death of such person . . . and that the principal, in committing the act, used, carried or threatened to use a firearm.” State *584v. Gonzalez, 300 Conn. 490, 496, 15 A.3d 1049 (2011);12 see also State v. Miller, 95 Conn. App. 362, 896 A.2d 844, cert. denied, 279 Conn. 907, 901 A.2d 1228 (2006). “Connecticut case law remains consistent ... in permitting the imposition of accessorial liability pursuant to § 53a-8, without requiring that the defendant intend to satisfy a criminal statute’s aggravating circumstance in cases wherein that aggravating circumstance does not have a specific mental state and requires only that the principal act with the general intent to perform the proscribed act.” State v. Gonzalez, supra, 506. Although the crime in Gonzalez was manslaughter in the first degree with a firearm as an accessory, and the crime at issue in this case is assault in the first degree with a dangerous instrument as an accessory, the statutory language as to the aggravating circumstances in each crime lacks the requirement of specific intent. See General Statutes § 53a-55a.13
Therefore, in the present case, the state was not required to prove that the defendant intended to cause serious physical injury by means of a dangerous instrument, or to prove that the defendant was even aware that another participant had a dangerous instrument or knife. See State v. Avila, 223 Conn. 595, 608, 613 A.2d 731 (1992). The use of a dangerous instrument simply represents the means by which the defendant is alleged to have participated in causing the serious physical *585injury, but to be culpable, the defendant only needs to have the intent to cause serious physical injury to another person, not the intent to do so with a dangerous instrument. The jury, therefore, reasonably could have inferred that the defendant intended to aid another to inflict serious physical injury upon Otero and that the principal used a dangerous instrument. We conclude, therefore, that the court properly denied the defendant’s postverdict motion for a judgment of acquittal.
II
The defendant’s second claim is that the court abused its discretion by denying his motion to suppress Otero’s out-of-court and in-court identifications. Specifically, he claims that, although the court found that the police identification procedure was unnecessarily suggestive,14 the court improperly concluded that Otero’s identifications of him nevertheless were rehable. We agree.
We first set forth the principles of law that guide our analysis. The parameters of the admissibility of pretrial photographic identifications and later in-court identifications by victims and witnesses in criminal cases are well established. At the outset, “[i]t is absolutely clear that the admission of evidence concerning a pretrial identification procedure that was unnecessarily suggestive and resulted in an unreliable identification violates a person’s rights to due process under both the federal and state constitutions.” State v. Reddick, 224 Conn. 445, 478, 619 A.2d 453 (1993) (Berdon, J., dissenting). In assessing a claim on appeal that evidence of both an out-of-court pretrial identification and an in-court identification should be suppressed, the defendant bears the initial burden of proving that the identification(s) resulted from an unconstitutional procedure. *586State v. Fullwood, 193 Conn. 238, 244, 476 A.2d 550 (1984). Our Supreme Court in Reddick prescribed a multistep cotuse for a trial court to follow when confronted with a claim that identification evidence should be excluded. State v. Reddick, supra, 465. The court must first determine whether the out-of-court identification procedure was unnecessarily suggestive. If the court answers that question in the negative, there is no need for the court to consider its reliability separately. State v. Outing, 298 Conn. 34, 55, 3 A.3d 1 (2010), cert. denied, 562 U.S. 1225, 131 S. Ct. 1479, 179 L. Ed. 2d 316 (2011). If, on the other hand, the court finds that the out-of-court identification procedure was unnecessarily suggestive, the court must then consider whether the identification procedure was, nevertheless, reliable based on an examination of the totality of the circumstances. State v. Taylor, 239 Conn. 481, 498, 687 A.2d 489 (1996), cert. denied, 521 U.S. 1121, 117 S. Ct. 2515, 138 L. Ed. 2d 1017 (1997).
Finally, if the court determines that an out-of-court identification has occurred under conditions that are unnecessarily suggestive and unreliable, the burden at trial is on the state to establish by clear and convincing evidence under the totality of the circumstances that the in-court identification is based upon the witness’ independent recollection, untainted by the faulty pretrial identification process.15 See United States v. Wade, 388 U.S. 218, 240, 87 S. Ct. 1926, 18 L. Ed. 2d 1149 *587(1967); see also Moore v. Illinois, 434 U.S. 220, 225-26, 98 S. Ct. 458, 54 L. Ed. 2d 424 (1977); State v. Mitchell, 204 Conn. 187, 204, 527 A.2d 1168, cert. denied, 484 U.S. 927, 108 S. Ct. 923, 98 L. Ed. 2d 252 (1987); State v. Guertin, 190 Conn. 440, 458-59, 461 A.2d 963 (1983); State v. Gordon, 185 Conn. 402, 418, 441 A.2d 119 (1981), cert. denied, 455 U.S. 989, 102 S. Ct. 1612, 71 L. Ed. 2d 848 (1982). In making this assessment, the task of the trial court is to determine whether an in-court identification that follows an impermissibly suggestive out-of-court identification has been tainted so as to render its admission a violation of a defendant’s due process rights. State v. Manson, 118 Conn. App. 538, 548, 984 A.2d 1099 (2009), cert. denied, 295 Conn. 902, 988 A.2d 878 (2010). In short, an in-court identification after an unnecessarily suggestive and unreliable out-of-court identification procedure should be allowed only “if it is purged of the taint of the defective pretrial procedure by establishment of the fact that it is based upon disassociated and independent observation.” (Internal quotation marks omitted.) State v. Piskorski, 177 Conn. 677, 741-42, 419 A.2d 866 (superseded by statute on other grounds as stated in State v. Canady, 187 Conn. 281, 283-84, 445 A.2d 895 [1982]), cert. denied, 444 U.S. 935, 100 S. Ct. 283, 62 L. Ed. 2d 194 (1979).
The court’s first task, to determine whether the pretrial identification procedure was unnecessarily suggestive, requires the court to consider first whether the procedure was suggestive and then, if so, whether the suggestive identification was nevertheless justified under the particular circumstances. State v. Reddick, supra, 224 Conn. 465. If the court finds that the procedure was unduly suggestive, the court’s assessment of whether the unduly suggestive identification and any subsequent in-court identification are nonetheless reliable must be based on an examination of the totality of the circumstances. Id. The United States Supreme *588Court in Manson v. Brathwaite, 432 U.S. 98, 97 S. Ct. 2243, 53 L. Ed. 2d 140 (1977), provided guidance for trial courts in assessing whether an unnecessarily suggestive pretrial identification may nonetheless be admitted at trial. The court enumerated a nonexclusive list of factors to be considered in assessing admissibility. Id., 114-16. Those factors include the opportunity of the witness to view the criminal at the time of the crime, the witness’ degree of attention, the accuracy of his or her prior description of the criminal, the level of certainty demonstrated at the confrontation and the time between the crime and the confrontation. Id.; see also State v. Gordon, supra, 185 Conn. 415. These factors, however, must be weighed against the corrupting effect of the suggestive identification itself, for “[w]here the ‘indicators of [a witness’] ability to make an accurate identification’ are ‘outweighed by the corrupting effect’ of law enforcement suggestion, .the identification should be suppressed.” Perry v. New Hampshire, U.S. , 132 S. Ct. 716, 719, 181 L. Ed. 2d 694 (2012); Manson v. Brathwaite, supra, 116; State v. Gordon, supra, 415.
The issue of whether an out-of-court identification was unnecessarily suggestive involves a mixed question of law and fact. State v. Marquez, 291 Conn. 122, 136, 967 A.2d 56, cert. denied, 558 U.S. 895, 130 S. Ct. 237, 175 L. Ed. 2d 163 (2009). Accordingly, our review is plenary. Id. Additionally, “because the issue of the suggestiveness of a photographic array implicates the defendant’s constitutional right to due process, we undertake a scrupulous examination of the record to ascertain whether the findings are supported by substantial evidence.” (Internal quotation marks omitted.) Id., 137; see State v. Mullins, 288 Conn. 345, 364, 952 A.2d 784 (2008). In conducting our review of the issue of reliability, “we examine the legal question of reliability with exceptionally close scrutiny and defer less than *589we normally do to the related fact finding of the trial court.” (Internal quotation marks omitted.) State v. Wooten, 227 Conn. 677, 688, 631 A.2d 271 (1993), quoting State v. Gordon, supra, 185 Conn. 416; see also State v. Marquez, supra, 137; State v. Figueroa, 235 Conn. 145, 155, 665 A.2d 63 (1995).
Finally, if we find that the court incorrectly permitted, as rehable, evidence flowing from an unreliable and unduly suggestive identification procedure, there remains the further issue of whether the ensuing judgment of conviction may be affirmed on the ground that the due process violation was, nevertheless, harmless in light of all the evidence correctly adduced at trial and untainted by the admission of an unreliable identification. This question requires, in part, that we discuss whether the harmless error doctrine is applicable in this legal context and, if so, the parameters of a harmless error analysis in the context of a constitutional error.
Having set forth an overview of the applicable law regarding the admissibility of identification evidence, we now turn to an analysis of the issue at hand, that is, whether the defendant’s due process rights were violated by the admission of unnecessarily suggestive and unreliable eyewitness identifications and, if so, whether the judgment must be reversed.
We first examine the question of whether the identification was unnecessarily suggestive.16 The following supplemental facts are relevant to a discussion of this issue. At trial, Hartford police Officer Jose Rivera testified that he spoke with Otero at the scene shortly after *590the assault and that Otero told him that he had initially been struck by a light-skinned black male, approximately five feet, eight inches tall and weighing 180 pounds, who had been the operator of an automobile that almost struck him and that the operator had been the first one to get out of the car. On cross-examination, Rivera confirmed that Otero had made no mention of any of the perpetrators having facial freckles. On direct examination, Otero indicated that he had not seen the initial perpetrator before and that he did not know his name. Rivera further testified that Otero indicated to him that he could not positively identify anyone else involved.
Following Rivera, Otero testified and made an in-court identification of the defendant. He also testified that he had made an out-of-court identification. Otero stated that in the weeks following the incident he received secondhand and thirdhand reports, giving him names of people who might have been involved, including the name “Hershey,” which he was told was the defendant’s street name.17 Otero stated that in May, 2008, while at the Hartford police station, he was shown a photographic array of eight individuals from which he was not able to make a positive identification. The defendant’s photograph was not part of this array. Otero testified that after he had been told by others, secondhand and thirdhand, that the defendant had been involved in the attack on him, he looked the defendant up on the department of correction website and discovered that the defendant was incarcerated. He stated that on the day he gave Hartford Detective Jeremy Bilbo the defendant’s name, Bilbo then brought up the defendant’s photograph on his computer. Otero testified that while he expected to see several photographs on the *591computer screen, there was only one photograph, that of the defendant, and that upon seeing the defendant’s photograph, he immediately identified him as the initial assailant.
Bilbo testified that in May, 2008, he showed Otero a photographic array with eight photographs that did not include the defendant. From this array, Otero was not able to make any positive identifications, although he did indicate that two of the photographs were similar to the person who attacked him. One of the photographs tentatively selected by Otero was that of Robert Acevedo. Bilbo indicated, as well, that in June, 2008, he prepared a photographic array for Otero and that this array included the defendant’s photograph. However, he did not show this array to Otero because he did not believe that Otero could identify any of his attackers. Nevertheless, Bilbo testified that six or seven months later he did show Otero a booking photograph of the defendant, with the name “Artis” printed across the front of the shirt of the person depicted, while telling Otero that it was a photograph of the defendant, that the defendant was a suspect in the case, and that he was seeking an arrest warrant for him. Contrary to Otero’s testimony, Bilbo claimed that Otero was not able to identify the defendant from this one photograph even though he told Otero that it was a photograph of the defendant. Bilbo stated, as well, that when shown the photograph of the defendant, Otero responded that he did not know who his attackers were and acknowledged that he could not identify them. Bilbo did not, at any time before or after he showed Otero the single booking photograph, display the photographic array to him that included the defendant’s photograph.
Confronted with the inconsistency between Otero’s testimony that he positively identified the defendant from the one photograph shown to him and Bilbo’s testimony that Otero did not make an identification, *592the court concluded, after hearing a motion to suppress, that Otero’s testimony was more credible in this regard than Bilbo’s.18 The court, therefore, concluded that Otero had made an out-of-court pretrial identification of the defendant as the initial assailant.
While in a claim of a wrongfully admitted photographic identification, our review of the record is more scrupulous than the norm, it is not our function to make our own credibility determination from the bare record. In this instance, the record provides ample basis for the court to have concluded, as it did, that Otero identified the defendant as his assailant from the one photograph shown to him by Bilbo.19
On the basis of these facts, there can be no question that this identification procedure was improper and that it was clearly not made necessary by any extenuating circumstances. Indeed, to characterize the process as merely suggestive belies the facts found by the court. It is undisputed that after Otero had told Bilbo of his belief in the defendant’s involvement in the assault that Bilbo then showed the defendant’s photograph to Otero while identifying the person in the photograph as the defendant and simultaneously telling Otero that the defendant was a suspect whose arrest he would be *593seeking. It would be difficult to conceive of a less neutral or more preemptive identification process than the one that occurred in this instance. It was against the backdrop of this dramatically improper identification process that the court was required to assess the identification’s reliability.20
Our Supreme Court has stated that “almost any one-to-one confrontation between a victim of a crime and a person whom the police present as a suspect is presumptively suggestive . . . because it conveys the message to the victim that the police believe the suspect is guilty.” (Citation omitted; internal quotation marks omitted.) State v. Wooten, supra, 227 Conn. 686; see also State v. Randolph, 284 Conn. 328, 385-86, 933 A.2d 1158 (2007) (danger of misidentification “will be increased if the police display to the witness only the picture of a single individual who generally resembles the person he saw” [internal quotation marks omitted]); State v. Crosby, 36 Conn. App. 805, 819, 654 A.2d 371 (“[without question, almost any one-to-one confrontation between a victim and a suspect must convey the message that the police have reason to believe him guilty, and is therefore unnecessarily suggestive”), cert. denied, 232 Conn. 921, 656 A.2d 669 (1995). In this *594instance, there was no implied message. To the contrary, Bilbo was clear and explicit in stating that the photograph was of the defendant, and that he was a suspect in the case whose arrest he was seeking. The process was not merely suggestive; it was preemptory and conclusive.
As to whether an overly suggestive identification procedure is necessary, the court will look to whether exigent circumstances existed, such as a show-up shortly after a crime while the victim’s memory is fresh and to quickly eliminate any innocent persons. State v. Wooten, supra, 227 Conn. 686. Our Supreme Court has stated that an immediate viewing of the suspect may be justified where “it [is] important for the police to separate the prime suspect gold from the suspicious glitter, so as to enable them ... to continue their investigations with a minimum of delay.” (Internal quotation marks omitted.) State v. Collette, 199 Conn. 308, 311, 507 A.2d 99 (1986). In this instance, in which the one photograph was shown to Otero months following the incident, the state properly makes no argument that exigent circumstances existed. As noted, Bilbo testified that by June, 2008, he had prepared a photographic array that included the defendant’s photograph but that he did not show it to Otero because he had said he could not identify his attackers. Then, months later, for reasons he is unable to fully explain, he stated that he showed Otero a photograph of the defendant while simultaneously identifying him by name and characterizing him as a suspect whose arrest he was seeking. The state makes no claim, nor do we find any basis for concluding, that this identification procedure was necessary.
Having reached the conclusion that the out-of-court identification procedure was constitutionally flawed, we turn next to a consideration of whether, despite the failings of the process, Otero’s out-of-court and in-court *595identifications were reliable under all the circumstances. In making this assessment, we track the factors outlined in Manson v. Brathwaite, supra, 432 U.S. 114-16, and we weigh those factors against the corrupting influence of the improper identification.21
A
The Opportunity of the Witness to View the Defendant At the Time of the Assault
This consideration implicates factors that relate to the victim’s condition at the time as well as the external environment. As to the former, and contrary to the trial court’s finding that Otero consumed a “couple of beers” in the hour and one-half before the incident, Otero acknowledged that between 11:30 p.m. and 1 a.m., moments before the altercation, he consumed “[a]t least four” beers, which he described as twelve ounce bottles of Heineken beer.22 One’s level of intoxication, we know *596from the reported research, plays a significant role in one’s powers of observation and concentration. See G. Gaulkin, Report of the Special Master, State v. Henderson, New Jersey Supreme Court, Docket No. A-8-08 (June 18, 2010) p. 47, available at http://www.judiciary.state.nj.us/pressrel/HENDER SON%20FINAL%20BRIEF%20.PDF%20(00621142).PDF (court noted, as undisputed, finding that “the effects of alcohol on identification accuracy show that high levels of alcohol promote false identifications” and that “low alcohol intake produces fewer misidentifications than high alcohol intake”).23
As to external influences on Otero’s opportunity to see his assailant during the altercation, Otero testified that shortly after he left Club NV, and while he was en route to Club Blu, he was nearly run over by an automobile. With respect to the fighting, although it is clear that at 1 a.m. on an early February morning it was dark, Rivera testified that, in his experience, the area is well lit. Nevertheless, the record is not explicit regarding the lighting at the exact location of the assault or the distance of any artificial fighting from the site of the altercation. We recognize, however, that the assault took place on an urban street and that, as observed by the court, the fighting was sufficient for Otero to have described the make and model of the car that almost struck him.
*597Another factor relating to the victim’s opportunity to observe his attacker is the amount of time involved in the incident. In this regard, Otero’s testimony was inconsistent as to how long the altercation lasted.24 According to Otero, during the brief duration of the incident, the passenger emerged from the automobile, approached him, struck him in the face and shoulder, and he punched back; each landed approximately two punches before Otero was struck from behind and landed on all fours. At one point during his testimony, Otero was unequivocal in stating that the verbal exchange between himself and his assailant lasted “less than two seconds” before the physical fight began. Otero further acknowledged that the physical altercation started with the assailant landing a punch to his face. At another point in his testimony, Otero stated that he had been face-to-face with the initial assailant for “five, ten” seconds. Elsewhere in his testimony, Otero stated, as to the incident, “I mean, it was fast. Everything happened so fast.”25
In its analysis of this factor, the court concluded that Otero had an adequate opportunity to see the assailant, and the court made reference to Otero’s testimony that he was face-to-face with the assailant for five to ten seconds. The court, however, made no explicit determination of the length of time Otero and his assailant were face-to-face, other than stating it was only a few *598seconds. Rather, the court based its conclusion on its view that “a good hard look will pass muster, even if it occurs during a fleeting glance”; (internal quotation marks omitted); quoting State v. Cubano, 203 Conn. 81, 95, 523 A.2d 495 (1987), and citing State v. Ledbetter, 185 Conn. 607, 615, 441 A.2d 595 (1981). Interestingly, the “fleeting glance” referred to in Cubano was a period of several minutes when the witness was within two or three feet of the defendant; State v. Cubano, supra, 95; and the “fleeting glance” in Ledbetter consisted of the witness viewing the robber’s face for approximately “fifteen or twenty seconds . . . .” State v. Ledbetter, supra, 615. Apparently finding comfort in the “fleeting glance” references of these earlier decisions, the court substantially compressed the time period in which a victim may be found to have had a “good hard look.”26
B
The Witness’ Degree of Attention
To buttress its conclusion regarding Otero’s opportunity to observe the defendant, the court noted not only *599that Otero gave an apt description of the defendant’s physical appearance but that he had been concentrating on his attacker. In this regard, the court noted, “[Otero’s] observation of and description of such [a] facial feature [as freckles] is not merely indicative of [a] perfectly adequate opportunity to observe but also confirms that his concentration was on the perpetrator’s face, unlike moments later when he was struck from behind and unable to see or identify his other attackers . . . .” This characterization, however, is inaccurate as, during the trial, Rousseau testified that when he met with Otero at the hospital shortly after the assault, Otero gave him descriptions of three people, one light-skinned black male, twenty-seven to twenty-eight years old, five feet, eight inches to five feet, nine inches tall, and 180 pounds, a light-skinned black male with freckles, twenty-seven to twenty-eight years old, five feet, nine inches, 200 pounds and stocky as the front seat passenger, and a black female, twenty-three to twenty-four years old, five feet, three inches, 120 pounds, whom he did not think was involved in the assault. Furthermore, in this regard, Bilbo testified that when he showed Otero an array of eight photographs, including a photograph of Robert Acevedo, Otero picked out Robert Acevedo and another person as similar to the person who had attacked him. This uncontra-dicted testimony of Otero’s detailed descriptions of three individuals allegedly at the scene of the attack and his successful selection of the photograph of Robert Acevedo as looking similar to his attacker contradict the court’s conclusion regarding the level of Otero’s concentration on his attacker.27
*600Also relevant to Otero’s opportunity to view the defendant as his initial assailant is the conflicting testimony regarding the location of the assailant immediately before the incident. Although Rivera testified that Otero told him at the scene that his initial assailant had been the driver of the Infiniti automobile, Otero testified that the assailant had alighted from the front passenger seat of the automobile. Miaño, however, testified that she had been the front right side passenger and that the defendant had been either in the vehicle’s backseat or in the process of getting into or out of the car.28 This conflicting evidence not only speaks to the confused circumstances regarding the fast-moving events that resulted in Otero’s injuries but also erodes confidence in the accuracy of his observations at the moment. Finally, it is noteworthy that Otero was not, at any time, able to provide a description, in any manner, of the clothes worn by his assailant.
Thus, although Otero testified that he and the defendant were face-to-face as they exchanged punches, the *601undisputed testimony from the record reveals that their confrontation in this melee of a few seconds took place in the context of a heated verbal exchange during which Otero was struck twice by his assailant, in the shoulder and facial area, and during which Otero struck the assailant two times. Although there was no direct evidence regarding Otero’s emotional condition at the time, it is reasonable to infer that, just having nearly been struck by an automobile and in the midst of a heated physical and verbal exchange, he was agitated and under stress. The notion that a person’s level of stress has a correlation to that person’s accuracy of observation and recall is not novel and has support in decisional law as well as in social science.29 In 1976, the United States Court of Appeals for the Sixth Circuit, in United States v. Russell, 532 F.2d 1063 (6th Cir. 1976), observed, “[t]here is a great potential for misidentification when a witness identifies a stranger based solely upon a single brief observation, and this risk is increased when the observation was made at a time of stress or excitement. . . . This problem is important because of all the evidence that may be presented to a jury, a witness’ in-court statement that ‘he is the one’ is probably the most dramatic and persuasive.”30 (Citations omitted.) Id., 1066-67. In a similar vein, the Utah *602Supreme Court observed, “[c]ontrary to much accepted lore, when an observer is experiencing a marked degree of stress, perceptual abilities are known to decrease significantly.” State v. Long, 721 P.2d 483, 489 (Utah 1986); see also State v. Henderson, 208 N.J. 208, 262, 27 A.3d 872 (2011) (“[w]e find that high levels of stress are likely to affect the reliability of eyewitness identifications”); State v. Cromedy, 158 N.J. 112, 124, 727 A.2d 457 (1999) (“ [t]here is a great potential for misidentification when a witness identifies a stranger based solely upon a single brief observation, and this risk is increased when the observation was made at a time of stress or excitement” [internal quotation marks omitted]); State v. Dubose, 285 Wis. 2d 143, 166 n.10, 699 N.W.2d 582 (2005) (same).
C
The Accuracy of the Witness’ Prior Description of the Defendant
As noted by the trial court, Otero’s identification of the defendant was accurate except with respect to his age. Rivera testified that Otero described his assailant as a fight-skinned black male, approximately five feet, eight inches tall and weighing approximately 180 pounds.31 Bilbo testified that Otero had described his assailant to another officer as the front right seat passenger of the automobile that almost struck him and that this person was a fight-skinned black male with freckles on his face. Rousseau testified that he had gone to the hospital after the incident and obtained from *603Otero descriptions of three individuals. Otero told Rousseau that the front seat passenger was a light-skinned black male with freckles, twenty-seven to twenty-eight years old, approximately five feet, nine inches, 200 pounds and stocky. Otero described another assailant as a light-skinned black male, approximately twenty-seven to twenty-eight years old, five feet, eight inches to five feet, nine inches tall, and weighing approximately 180 pounds. The similarities between these two descriptions weigh against their singularity.32 Otero described a third person, who he did believe was directly involved, as a black female, age twenty-three to twenty-four years old, five feet, three inches tall and approximately 120 pounds.
Rousseau testified that, at the hospital, Otero told him that he did not think that he could identify any of his attackers. We know from the record that, at the time of the attack Otero was thirty-six years old, and so he was describing the two males who attacked him as eight to nine years younger than he was. We know, as well, from the record, that, on February 15, 2008, the defendant was thirty-seven years old, or nine to ten years older than the assailant initially described by *604Otero on the day of the incident. While, in other respects, Otero’s description of his initial assailant appears to be consistent with the defendant (as well as with the other male who is described), we do not have, from the record, any reference data with which to draw any conclusions regarding the relative distinctiveness of the assailant’s description.
D
The Level of Certainty Demonstrated at the Confrontation
This factor warrants little discussion because, at the time of the confrontation, Otero was told, and not asked, by Bilbo that the photograph he was being shown was that of the defendant and that the defendant was a suspect in the case whose arrest Bilbo was seeking. We know, as well, that before this procedure, Otero had heard from “[s]econd, thirdhand” sources that the defendant had been involved in the altercation and that Otero, in fact, had relayed the defendant’s name to the police. Therefore, Otero went to the police department with the defendant in his mind as one of the assailants, a belief that immediately was buttressed by Bilbo’s confirming to him that the defendant was a suspect whose arrest he was in the process of seeking.33 Thus, while the record is clear that Otero testified in court that, upon seeing the photograph of the defendant he identified him, with certainty, as his initial assailant, little weight should be accorded to Otero’s level of certainty, *605given the prelude to the photographic identification.34 The trial court, however, appears to have given great weight to this factor. In placing on the record its reasons for denying the motion to suppress, the court stated: “Most significantly and as is apparent from much of the foregoing, the level of certainty of Mr. Otero’s identification of the accused was exceedingly high. ” Similarly, with regard to the in-court identification, the court observed: “With respect to his in-court identification of the defendant at the evidentiary hearing on this motion, [Otero] expressed or displayed absolutely no uncertainty, hesitation, or equivocation. In my view, Mr. *606Otero’s level of certainty was, as stated, very high.” That the court relied considerably on this factor is self-evident from the record. Equally evident from the volumes of social science research on this factor is the lack of any correlation between a victim’s level of confidence in his or her identification and its accuracy.
E
The Time Between the Crime and the Confrontation
The next consideration relates to the timing of the identification. As noted, by June, 2008, following the February, 2008 incident, Bilbo was in possession of a photographic array that included a photograph of the defendant. Otero, however, was not shown the array, and instead, he was shown a single photograph of the defendant months later.35 In Neil v. Biggers, 409 U.S. 188, 93 S. Ct. 375, 34 L. Ed. 2d 401 (1972), while not finding that the lapse of time between a criminal event and a subsequent identification procedure required exclusion of the identification evidence, the United States Supreme Court nevertheless expressed the view that a lapse of seven months between the date of a crime and a subsequent confrontation “would be a seriously negative factor in most cases.” Id., 201.
*607The New Jersey Supreme Court, in a recent opinion, fashioned a protocol for police identification procedures. The court observed: “Memories fade with time. And as the [s]pecial [m] aster observed, memory decay ‘is irreversible’; memories never improve. As a result, delays between the commission of a crime and the time an identification is made can affect reliability. That basic principle is not in dispute.” State v. Henderson, supra, 208 N.J. 267. The court continued: “A meta-analysis of fifty-three ‘facial memory studies’ confirmed that memory strength will be weaker at longer retention intervals [the amount of time that passes] than at briefer ones. ... In other words, the more time that passes, the greater the possibility that a witness’ memory of a perpetrator will weaken. . . . However, researchers cannot pinpoint precisely when a person’s recall becomes unreliable.” (Citations omitted.) Id. Suffice to say, a delay of months between the date of the offense and the presentation of the defendant’s photograph to Otero is not an indicator of reliability. Finally, because the court did not make a factual finding as to when the defendant’s photograph was shown to Otero, it was not in a position to assess this factor fairly. Rather, the court appears to have dismissed this factor as unimportant in light of other indicia of reliability it found.
At trial, the court’s assessment of reliability required a balancing analysis. Now, we, too, must do so on review of this mixed question of law and fact.36 Our review of the record suggests, however, that although the court assessed some of the factors listed in Manson v. Brathwaite, supra, 432 U.S. 114-16, in its reliability determination, it failed to give proper weight to the corrupting *608effect of this most inappropriate identification confirmation procedure. In weighing those factors, the trial court gave inappropriate weight to Otero’s level of certainty while dismissing, as insignificant, the internal and external circumstances of the assault regarding Otero’s condition during the melee and the impact Otero’s own investigation of the assault may have had on his readiness to confirm that the photograph shown to him by Bilbo was that of the defendant. Additionally, by not establishing the date or month on which the identification was made, the court failed to consider the impact of such a delay on Otero’s ability to identify his initial assailant accurately.
Contrary to the finding by the trial court, our application of the factors listed in Manson v. Brathwaite, supra, 432 U.S. 114-16, considered against the backdrop of the extraordinarily overbearing manner of the identification procedure, leads us to the conclusion that the pretrial identification of the defendant by Otero was not reliable and that Otero’s subsequent in-court identification was not sufficiently removed from the taint of the earlier out-of-court identification to be independently reliable. We conclude, therefore, that both identifications should have been suppressed as unreliable.
We turn now to the question of harm. At the outset, we note that our Supreme Court has, as a matter of policy, emphatically rejected the notion that the doctrine of harmless error is available to uphold a conviction in which the trial court admitted unnecessarily suggestive and unreliable witness identification testimony. State v. Gordon, supra, 185 Conn. 419-20. In Gordon, the court opined: “The state urges that even if the trial court erred in admitting both the station house and the in-court identifications of the defendant by the victim, such error would be harmless because of other overwhelming evidence that the defendant was the assailant.” Id., 419. Rejecting this argument, the *609court stated: “Ordinarily the burden of establishing that harm resulted from atrial court error rests on the appellant. . . . However, there are some constitutional rights so basic to a fair trial that their infraction can never be treated as harmless error. ... If error touches a less basic constitutional right, we sometimes apply the harmless error exception, but only sparingly, in a few, discrete circumstances. . . . Thus, we refuse to expand our harmless constitutional error doctrine to the discrete circumstances of unnecessarily suggestive and unreliable identifications, the admission of which significantly impairs the truth finding function of the jury. . . . Were we to do so we would fail to correct negligent infractions of constitutional rights and tempt some public officials to overstep the law in their zeal to convict the guilty. Some would yield to such temptation. The devastating nature of both negligently and deliberately obtained, unreliable eyewitness identifications would inevitably lead to the conviction of innocent persons. Hence sound judicial policy requires reversal whenever the erroneous admission of an unnecessarily suggestive and unreliable identification has violated a defendant’s constitutional rights.”37 (Citations omitted; internal quotation marks omitted.) Id., 419-20.
*610Our Supreme Court recently has stated: “When an [evidentiary] impropriety is of constitutional proportions, the state bears the burden of proving that the error was harmless beyond a reasonable doubt. . . . [W]e must examine the impact of the evidence on the *611trier of fact and the result of the trial. ... If the evidence may have had a tendency to influence the judgment of the jury, it cannot be considered harmless. . . . That determination must be made in light of the entire record [including the strength of the state’s case without the evidence admitted in error].” (Internal quotation marks omitted.) State v. Gonzalez, 302 Conn. 287, 307, 25 A.3d 648 (2011).
In analyzing harm in other constitutional contexts, our Supreme Court has also opined: “Whether such error is harmless in a particular case depends upon a number of factors, such as the importance of the witness’ testimony in the prosecution’s case, whether the testimony was cumulative, the presence or absence of evidence corroborating or contradicting the testimony of the witness on material points, the extent of cross-examination otherwise permitted, and, of course, the *612overall strength of the prosecution’s case. . . . Most importantly, we must examine the impact of the evidence on the trier of fact and the result of the trial. ... If the evidence may have had a tendency to influence the judgment of the jury, it cannot be considered harmless.” (Emphasis added; internal quotation marks omitted.) State v. Rolon, 257 Conn. 156, 174, 777 A.2d 604 (2001).38
The relationship between properly admitted evidence and improperly admitted evidence impheating a constitutional right is significant to our analysis. While consideration of both the good and bad evidence is appropriate, the properly admitted evidence has to be beyond strong in order to uphold a conviction. In State v. Angel T., 292 Conn. 262, 277 n.10, 973 A.2d 1207 (2009), our Supreme Court described the nexus between the proper and improper trial evidence in this manner: “This is not a situation where the case against the defendant was otherwise ‘so overwhelming’ that the constitutional error did not, beyond a reasonable doubt, contribute to the conviction.” In a similar vein, *613in State v. Gerardi, 237 Conn. 348, 677 A.2d 937 (1996), a case involving a constitutional error unrelated to identification, our Supreme Court stated: “[W]e cannot conclude with any degree of certainty that the evidence adduced at trial was so overwhelming that it foreclosed the possibility that the jury may have relied upon the improper mandatory presumption regarding possession rather than upon that evidence.” Id., 363. Additionally, in State v. Gonzalez, supra, 302 Conn. 310, our Supreme Court, adjudicating a claim of improper admission of a statement by the defendant, concluded that the evidence against the defendant was “not so overwhelming that we are convinced beyond a reasonable doubt that the admission of his improperly obtained narration was harmless.” Thus, the state can not prevail in a harmless error analysis simply by demonstrating that the properly admitted evidence, absent the tainted evidence, was merely adequate for a conviction. Id., 306-307.
Even though we are persuaded that the legal posture of the case at hand is indistinguishable from Gordon, we conduct a harmless error analysis. At the outset, we note that the state’s case against the defendant was not overwhelming. To the contrary, there was no physical evidence at the scene, nor was there any forensic evidence. No knife or any dangerous instrumentality was found at the crime scene or connected to this incident, and there were no statements from the defendant. Rather, the state’s evidence consisted, mainly, of the testimony of Otero and Miaño. The state’s additional witnesses, with one exception, were all police officers whose information, in large measure secondhand, came from Otero and Miaño. The one witness for the state who was not a police officer, Rego, an employee of Club Blu, testified regarding the physical layout of the scene and the injury to Otero’s thumb and stomach, evidence that did not, in any manner, implicate the defendant.
*614As to Miaño, a fair review of her testimony reveals that she stated that the defendant traveled with her and others to and from the area of the altercation on the night in question. She placed the defendant at the scene of the altercation and as a participant. However, her testimony regarding the circumstances of the altercation was confused and imprecise, her ability to observe the events accurately was unclear, and her familiarity with Otero together with her relationship with Robert Acevedo reasonably could have put her objectivity in doubt for the fact finders.
Furthermore, Miaño testified that she, together with the defendant and two others, Robert Acevedo and Anna Acevedo,39 arrived at Club NV at approximately 11 p.m. While at Club NV, Miaño did not see the defendant although she did spend time with Otero, giving him a hug, having him take a photograph of her with her camera and later exchanging contact information with him while leaving. Significantly, Miaño acknowledged that, by the time she left the club, she was “tipsy” after having consumed two to three “[s]ex on the beach” mixed drinks containing vodka.
As to the altercation itself, Miaño acknowledged that when she, Robert Acevedo and Anna Acevedo got into the automobile, she was uncertain of the defendant’s whereabouts and was unsure as to whether the defendant had gotten into the automobile before the altercation took place. Although Miaño asserted that the defendant was present during the altercation and that she saw one of the two men push the other, she also acknowledged that she did not see the argument that she claimed occurred between the defendant and Otero, or the physical altercation that she claimed took place *615between them.40 Additionally, although Miaño testified on direct examination that she saw blood on the defendant’s shirt after the altercation, she admitted on cross-examination that she had not, in fact, seen any blood on the defendant. We acknowledge that Miaño testified that earlier in the evening the defendant had indicated that he had wanted to leave his knife in the automobile before going into Club NY and that, although Miano’s testimony regarding the actual altercation was confused and inconsistent, she placed the defendant at the site of the altercation as a participant. From this testimony, the jury reasonably could have concluded that the defendant was a participant in the assault that resulted in Otero’s injuries.
Additionally, from our review of Miano’s testimony, we acknowledge that the jury could have resolved any credibility and impartiality issues in favor of believing her testimony and could have drawn reasonable inferences from it, and, on that basis alone, the evidence may have been sufficient to sustain the jury’s guilty verdict. Our conclusion that the jury could have found the defendant guilty on the basis of Miano’s and other properly admitted testimony should not, however, be equated with a finding that the properly admitted evidence of the defendant’s guilt was so overwhelming that we can determine, beyond a reasonable doubt, that it was not a factor in the jury’s verdict. Indeed, the state’s evidence was far from overwhelming.
As noted, harmlessness must be analyzed in context. Thus, in order to affirm the judgment, we must be able to declare that, in light of the properly admitted evidence, the improperly admitted evidence could not have *616affected the jury verdict. State v. Gonzalez, supra, 302 Conn. 306-307. This is particularly true in a situation involving eyewitness identification. As Justice William J. Brennan, Jr., of the United States Supreme Court observed: “[D] espite its inherent unreliability, much eyewitness identification evidence has a powerful impact on juries. Juries seem most receptive to, and not inclined to discredit, testimony of a witness who states that he saw the defendant commit the crime. [E]yewitness testimony is likely to be believed by jurors, especially when it is offered with a high level of confidence, even though the accuracy of an eyewitness and the confidence of that witness may not be related to one another at all. All the evidence points rather strikingly to the conclusion that there is almost nothing more convincing than a five human being who takes the stand, points a finger at the defendant, and says That’s the one!” (Internal quotation marks omitted.) Watkins v. Sowders, 449 U.S. 341, 352, 101 S. Ct. 654, 66 L. Ed. 2d 549 (1981) (Brennan, J., dissenting). With implicit agreement, our Supreme Court has noted: “Common sense suggests, and research confirms, that eyewitness identification is an important form of evidence.” State v. Ledbetter, supra, 275 Conn. 575. Additionally, the court observed: “Eyewitness identification evidence is particularly persuasive when the witness exhibits confidence in the identification.” Id.
The point made by Justice Brennan and echoed by Justice Richard N. Palmer in his concurrence in State v. Outing, supra, 298 Conn. 105; see footnote 29 of this opinion; was surely not lost on the prosecutor in the case at hand. A review of closing arguments reveals that the prosecutor began his argument to the jury by emphasizing Otero’s identification of the defendant, going to the extent of asking the jury to accept, as credible, Otero’s identification testimony against the testimony of Bilbo that Otero had not made a pretrial *617identification. Indeed, in urging the jury to accept Otero’s identification of the defendant as accurate, the prosecutor argued: “Don’t blame Mr. Otero for the indifference and the incompetence of the Hartford police department.” The prosecutor’s argument to the jury regarding Otero’s identification was neither brief nor incidental. Furthermore, despite Bilbo’s claim that Otero had not identified the defendant when shown his photograph in December, 2008, and in fight of Otero’s testimony to the contrary, the court charged the jury that the state had presented both out-of-court and in-court identification testimony and gave a lengthy charge on the topic of eyewitness identification. Thus, it cannot reasonably be said that Otero’s identification testimony was insignificant to the state’s presentation or to the court’s instructions to the jury. Indeed, from a fair reading of the transcript, it appears that Otero’s out-of-court and in-court identifications of the defendant were key elements, if not the centerpiece, of the state’s case.
On the basis of our review of this record, we are persuaded that there is no reasonable basis to conclude that the jury was not likely influenced by Otero’s improperly admitted out-of-court and in-court identifications of the defendant. We conclude, therefore, that, to the extent the improper admission of unreliable identification evidence is subject to harmless error analysis on appeal, the state has not met its burden of demonstrating beyond a reasonable doubt that the court’s incorrect admission of Otero’s identifications of the defendant constituted harmless error.
The judgment is reversed and the case is remanded for a new trial.
In this opinion PETERS, J., concurred.
