By a twenty-nine count indictment filed in August 1981, appellant was charged with multiple offenses stemming from seven incidents which occurred between July 1980 and April 1981 in upper Northwest Washington. Appellant moved in timely fashion to assign each count a separate trial; instead, the trial court joined the counts so as to provide two separate trials.1 A jury convicted appellant, at his first trial, of two counts of second-degree burglary,2 D.C. Code § 22-1801(b) (1981); one count of pet-it larceny, id. § 22-2202, and one count of destruction of property, id. § 22-403. At appellant’s second trial, a jury found him guilty on all counts, including sodomy, id. § 22-3502; first-degree burglary while armed, id. §§ 22-1801(a), -3202; armed robbery, id. §§ 22-2901, -3202; assault while armed, id. §§ 22-501, -502, -3202; and rape, id. § 22-2801.
Appellant claims error at both trials. As to the first, he cites the trial court’s failure to sever counts.3 Appellant also claims that the evidence supporting one burglary count was insufficient. Challenging the verdict at his second trial, appellant cites as erroneous evidentiary rulings by the trial court. Finding all of these claims unpersuasive, we affirm.
I
Appellant’s first trial concerned offenses which allegedly occurred during two incidents. The type of errors alleged by appellant require a recitation of the facts adduced at trial.
The Koenig Incident
At 4:00 p.m., on July 21, 1980, David McHenry saw a “young black male tampering with” an apartment window in his building, which was located near 17th and P Streets, N.W. The stranger, later identified as appellant, saw McHenry, and quickly boarded a Metrobus. Soon after, however, McHenry again saw appellant near the door of the same apartment; he called the police to report a burglary in progress.4 Standing near the door, McHenry heard someone “rustling around.” As appellant left the apartment, McHenry asked what he was doing. Appellant responded suspiciously.5 McHenry identified appellant to arriving police officers. Appellant was found to possess several items claimed by Mrs. L. Koenig, the tenant of the burgled apartment. Appellant’s fingerprints were found in her apartment, and Mrs. Koenig testified that she had not authorized appellant’s entry.
The Rodenbeck Incident
Early in the afternoon of Halloween 1980, Mrs. A. Rodenbeck noticed a young *764man walk “right by” her as she helped her small son from his carseat. Moments later entering her home in the 3300 block of 19th Street, N.W., she saw the same man in her neighbor’s yard. Mrs. Rodenbeck called the police, and waited for them in her car after she heard the sound of breaking glass in her basement. She gave arriving police officers her house key.
Metropolitan Police Officer Warren Frye circled around to the back of Mrs. Roden-beck’s house. The glass in the basement window had been shattered. Officer Frye looked through the window and saw appellant “peering” from behind a partition. He identified himself as a police officer,6 and asked appellant to state his business. Appellant explained that he was “doing work in the house.” As appellant climbed out of the window, he carried a briefcase and wore a glove on his left hand.7 Appellant was arrested when he attempted to flee before being brought to Mrs. Rodenbeck for identification.
At trial, appellant denied participation in both incidents. His motion to acquit was granted as to a count of first-degree burglary with intent to assault.8
Appellant now alleges error stemming from the trial court’s refusal to grant the motion to acquit as to first-degree burglary with intent to steal. He also alleges error in the refusal to sever the respective counts arising from each incident. We treat each in turn.
A.
A judgment of acquittal must be granted “... if the evidence is insufficient to sustain a conviction.” Super.Ct.Crim.R. 29(a). In addressing such a motion,
the trial judge must consider whether reasonable jurymen must necessarily have a reasonable doubt or whether, on the other hand, the evidence was such that a reasonable mind might fairly have a reasonable doubt or might not have such doubt.
Crawford v. United States, 126 U.S.App. D.C. 156, 158, 375 F.2d 332, 334 (1967) (emphasis in original); see also Curley v. United States, 81 U.S.App.D.C. 389, 392-93, 160 F.2d 229, 232-33, cert. denied, 331 U.S. 837, 67 S.Ct. 1511, 91 L.Ed. 1850 (1947).
The scope of this court’s inquiry is quite narrow. If the record evidence fairly allows a reasonable jury to find guilt beyond a reasonable doubt, then we must uphold the denial of appellant’s motion for acquittal. Dyson v. United States, 450 A.2d 432, 436 (D.C.1982); Byrd v. United States, 388 A.2d 1225, 1229 (D.C.1978). The evidence need not require a guilty verdict; it need only allow for it. Chaconas v. United States, 326 A.2d 792, 798 (D.C.1974). In short, we may only reverse if the conviction is without evidential support. See Hack v. United States, 445 A.2d 634, 639-40 (D.C.1982).
Applying these standards, we are constrained to hold that the denial of appellant’s motion was not error. Contrary to appellant’s assertion, it was not necessary that the jury consider evidence relating to the Koenig incident in order to find an intent to steal from Mrs. Rodenbeck. Evidence of intent in the Rodenbeck incident was circumstantial, but nonetheless probative. See Dyson, supra, 450 A.2d at 436; Massey v. United States, 320 A.2d 296, 299-300 (D.C.1974) (circumstantial evidence of intent to steal); see also Washington v. United States, 105 U.S.App.D.C. 58, 61, 263 F.2d 742, 745, cert. denied, 359 U.S. 1002, 79 S.Ct. 1142, 3 L.Ed.2d 1032 (1959) (defend*765ant’s unexplained presence in victim’s house, after gaining access by “force and stealth” through window, supported intent to steal inference); Johnson v. United States, 293 A.2d 269, 271 (D.C.1972) (possession of gloves and “ordinary accouterments of a burglar” supported inference that defendant was intruder).
B.
Appellant did not renew his severance motion after the incidents were joined at his first trial. Consequently, we look only to see if there was plain error in the refusal to sever. We find none.
D.C.Code § 23-311(a) (1981) and Super.Ct.Crim.R. 8(a) permit joinder if the offenses “are of the same or similar character . ... ” Hackney v. United States, 389 A.2d 1336, 1344 (D.C.1978), cert. denied, 439 U.S. 1132, 99 S.Ct. 1054, 59 L.Ed.2d 95 (1979). A defendant may move, under Super.Ct.Crim.R. 14, to sever joined counts if he establishes that such joinder presents “the most compelling prejudice,” when balanced against the strong social policy to “conserve state funds, limit inconvenience, and avoid delay.” Robinson v. United States, 452 A.2d 354, 358 (D.C.1982) (citing Arnold v. United States, 443 A.2d 1318, 1322 (D.C.1982)). In ruling on the trial court’s refusal to sever, we may reverse only for a clear abuse of discretion. Robinson, supra, 452 A.2d at 358; Warren v. United States, 436 A.2d 821, 831-32 (D.C.1981); Winestock v. United States, 429 A.2d 519, 526 (D.C.1981); Crisafi v. United States, 383 A.2d 1, 5-6 (D.C.), cert. denied, 439 U.S. 931, 99 S.Ct. 322, 58 L.Ed.2d 326 (1978).
Allegations of prejudice will generally be unpersuasive if the evidence relating to one joined count would be admissible in the separate trial of another. Winestock, supra, 429 A.2d at 527; Bowyer v. United States, 422 A.2d 973, 977 (D.C.1980); Hackney, supra, 389 A.2d at 1345; Samuels v. United States, 385 A.2d 16, 18 (D.C.1978). We think that in this case, evidence relating to the Koenig incident would have been admissible in a separate trial of offenses committed at the Rodenbeck house.9 Appellant has not otherwise established the undue prejudice required by our cases. See Bowyer, supra, 422 A.2d at 977. No evidence shows, for example, that the jury was confused as to which incident particular evidence related, or that evidence was improperly cumulated to find guilt.10 See id. *766Indeed, the jury did not even find appellant guilty of first-degree burglary with intent to steal; he was found guilty of a lesser included offense. This belies a finding of prejudice. In any event, we do not find the refusal to sever clearly erroneous.
II
Appellant’s second trial concerned twenty-two counts arising from five incidents which occurred between September 1980 and April 1981 in upper Northwest Washington. Appellant does not contest the joinder of these counts. Rather, he alleges that the trial court erroneously allowed certain witnesses to testify for the government. Appellant argues that the trial court should have evaluated the admissibility of certain circumstantial evidence under standards articulated in Drew, supra, as it related to “prior crimes” or “bad acts.” Appellant also challenges the admission of a prior consistent statement, which was used to rehabilitate a victim’s direct testimony. We review the facts adduced at trial before addressing the merits of these two claims.
A.
The Gallatin Street Incident
On the morning of September 25, 1980, Mrs. J.S.11 was alone in the bedroom of her home, in the 1500 block of Gallatin Street, N.W. A masked intruder, who carried a knife, entered the room, bound her wrists and covered her face with a stocking.12 He forced her into the bathroom and sexually molested her. The intruder thereafter fled. A small amount of cash and a framed pho-tograpn of complainant’s son were subsequently discovered to be missing. The photograph was later recovered from appellant’s house.
The Argyle Terrace Incident
On the morning of October 2, 1980, Mrs. M.R. and her young son arrived at the Argyle Terrace address where she worked as a housekeeper. A masked man pushed his way into the house from behind. There was a struggle, during which the victim removed her attacker’s mask. The man threatened the boy with a saw blade he carried, causing the woman to comply with his demands. The attacker took her into the bathroom and sexually assaulted her. He then fled. At a subsequent lineup, the complainant was unable to positively identify appellant; she thought that he might be the attacker. This tentative identification was repeated before the grand jury. During her videotaped “in-court” testimony,13 the complainant stated that she was certain that appellant had attacked her, and that she had been similarly positive at the lineup and grand jury.14
The Macomb Street Incident
At noontime on November 26, 1980, Mrs. E.S. was attacked shortly after entering her home in the 3200 block of Macomb Street, N.W. Her assailant was a black man, who wore a stocking mask and carried a gun. The complainant was beaten into unconsciousness while resisting her assailant’s advances,15 and was later discovered by police lying nude on her bed suffering from a *767serious head wound.16 A camera was found to be missing from the home.
The witness was unable to identify her attacker, but four children saw a man running from her house shortly after the attack. Two of the children tentatively identified appellant at the lineup.17
The Second Argyle Terrace Incident
At noontime on December 15, 1980, Mrs. J.K. was attacked in her home on Argyle Terrace, N.W., by a man who posed at her door as a salesman.18 The man pushed through the door, grabbed the complainant by the neck, and dragged her into a bathroom. He pulled a stocking mask over his face and covered hers. The man then sexually assaulted her. He took several hundred dollars in cash, credit cards, and the victim’s wallet, which contained photographs of her children. An instamatic camera was later reported missing.
Several days later, the complaining witness received a telephone call from her attacker. The man told her that “the Lord cares,” and he offered to return the stolen items. Several items, enclosed in Christmas cards, subsequently were mailed to her. A police expert matched writing on the cards to exemplars taken from appellant. The witness identified appellant at the lineup, after first hearing him speak.19
The Decatur Street Incident
Shortly after seeing her husband off to work on the morning of April 15,1981, Mrs. V.P. opened the door of her home in the 1200 block of Decatur Street, N.W., for a persistent man who carried a package. The man pushed his way into the house, struck the complainant and forced her into the upstairs bathroom. He raped her there. The assailant left the residence with some silver dollars and assorted change. Later, the complaining witness selected appellant’s photograph from an array,20 tentatively identified him at the lineup, and identified him in court as the rapist.21
Other Circumstantial Evidence
Over appellant’s objection and after a lengthy proffer by the government, the trial court permitted the prosecutor to call other witnesses, whose testimony is recounted here.
Lola Clayton and Bertha Bolden
Lola Clayton testified that on January 27, 1981, she saw appellant peering into her neighbor’s house.22 Later that same afternoon, Mrs. Clayton again saw appellant, this time in her garage, preparing to smash her kitchen window with a brick.23 Mrs. Clayton verbally accosted appellant, and received a suspicious explanation for his presence.24 She called the police.
*768Bertha Bolden testified that she watched appellant walk up to her house near 16th and Farragut Streets on January 28, 1981. Lola Clayton had told her of appellant’s looking into her house on the day before. Mrs. Bolden asked appellant what he wanted. Appellant explained that he was selling tickets, but when Mrs. Bolden threatened to call the police, he walked away.
Robert McGonnell and Michael Baltes
These police officers testified that they spotted appellant walking around 16th and Upshur Streets, N.W., at 10:00 a.m. on January 27, 1981. They stopped appellant and asked what he was doing, after watching him walk out from between two houses on 18th Street, N.W.25 Appellant told the officers that his name was “Quinton Newman,” and claimed that he was on the way to do some yard work. Officer McGonnell saw a nylon stocking sticking out from under appellant’s hat.
Officer Baltes testified that several weeks later appellant was seen at 16th and Decatur Streets, N.W., following a woman who had just stepped off a Metrobus. He was later seen “between two houses in some bushes”26 in the 1500 block of Decatur Street, N.W.27
Christopher L. Enourato
Officer Enourato testified that he saw appellant “just walking up the street” on the 4300 block of Argyle Terrace, N.W., in February 1981, but decided to watch him because he was “acting suspicious. 28 Appellant was seen stepping up to a porch, only to leave a moment later, and then entering a house on 14th Street, N.W., through the front door.29
Thomas Farley
Officer Farley testified that he saw appellant approach several houses on Argyle Terrace, N.W., near Upshur Street, in March or April 1981. Appellant rang doorbells, checked windows, and looked into driveways and garages. Appellant could not fully explain his behavior to the officer when stopped,30 but gave his correct name. No warrants were outstanding for appellant, so he was allowed to leave.
Warren Frye
The officer who arrested appellant at the Rodenbeck house, see ante at 763, testified solely that he “obtained” a UNICEF Christmas card catalog from appellant on the 3300 block of 19th Street, N.W.31 A stipulation that the catalog did not contain the type of cards sent to Mrs. J.K., see ante at 767, was given to the jury.
B.
Appellant does not contend that the five incidents recounted above were improperly joined. He argues that, because the other circumstantial evidence “showed [appellant] engaging in criminal activity, behavior of a nefarious sort, or activity which showed him to be a ‘bad man’ likely to run afoul of *769the police,” the trial judge should have concluded that the evidence was inadmissible under any exception stated in Drew, supra. In short, appellant claims that the circumstantial evidence of appellant’s “bad acts” was relevant only to establish that he had a criminal disposition.32 We disagree.
A fundamental tenet of our jurisprudence is that guilt must be determined by reference to facts pertinent to the specific offenses charged; extraneous criminal behavior may not be used to prove guilt through establishing the defendant’s “general bad character, or his tendency to commit the particular offense charged.” Bridges v. United States, 881 A.2d 1073, 1075 (D.C.1977), cert. denied, 439 U.S. 842, 99 S.Ct. 135, 58 L.Ed.2d 141 (1978) (citing Tinsley v. United States, 368 A.2d 531, 533 (D.C.1976)). In Drew, supra, appellant’s conviction was reversed because the prosecutor “repeatedly referred” to evidence of a completed robbery to establish that appellant probably was involved in an attempted robbery. Both offenses had been joined in the same trial. Id., 118 U.S.App.D.C. at 13, 331 F.2d at 87. The Drew court found that the defendant had been prejudiced by the overlapping of the evidence, because the jury may have become confused as to which evidence could be used to find guilt on each respective count.33 Id., 118 U.S.App.D.C. at 19, 331 F.2d at 93.
Drew teaches, however, that evidence of “prior crimes” may be used to establish propositions other than guilt:
Evidence of other crimes is admissible when relevant to (1) motive, (2) intent, (3) the absence of mistake or accident, (4) a common scheme or plan embracing the commission of two or more crimes so related to each other that proof of the one tends to establish the other, and (5) the identity of the person charged with the commission of the crime on trial. When the evidence is relevant and important to one of these five issues, it is generally conceded that the prejudicial effect is outweighed by the probative value.
Id., 118 U.S.App.D.C. at 16, 331 F.2d at 90; see Brooks, supra, 448 A.2d at 257; Hackney, supra, 389 A.2d at 1344; Bridges, supra, 381 A.2d at 1075. If the evidence may be characterized within one of the enumerated exceptions, the trial court must then determine, using the usual relevancy test, if probative value outweighs prejudicial impact. Samuels v. United States, 385 A.2d 16, 18-19 (D.C.1978). Unless the “prior crimes” evidence fits within an exception, prejudice is presumed. Willcher v. United States, 408 A.2d 67, 75 (D.C.1979).
In this jurisdiction, Drew has been cited predominately in cases involving join-der and severance. E.g., Bowyer, supra, 422 A.2d at 977; Bridges, supra, 381 A.2d at 1075. In these cases and others, the “prior crimes” or “bad acts” evidence concerned defendants’ actions that were, by their nature, criminal offenses. That the acts were not formally adjudicated as crimes did not, of course, weaken Drew’s applicability. See, e.g., Page v. United States, 438 A.2d 195 (D.C.1981); Willcher, supra. Drew analysis has not been used when the circumstantial evidence in and of itself could not be characterized as establishing criminal behavior. E.g., Punch v. United States, 377 A.2d 1353, 1358 (D.C.1977) (possession of hats and stocking masks), cert, denied, 435 U.S. 955, 98 S.Ct. 1586, 55 L.Ed.2d 806 (1978). We conclude that Drew does not control the question of admissibility in the ease before us because, in order to be characterized as Drew -type evidence, the acts portrayed must be minimally in the nature of a criminal offense. The “other” evidence *770in this case does not meet this requirement.34
In deciding to admit the “other evidence,” the trial judge warned both attorneys to avoid elicitation of any reference to appellant’s prior criminal behavior.35 This admonition was scrupulously followed. As reflected in the record, and recounted above, the circumstantial evidence did not show appellant committing any criminal acts. It established that, over a three-month period in a particular neighborhood,36 appellant rang doorbells, peered into windows, wandered between houses and bushes, posed as a salesman and workman, followed one woman, and gave an alias to an inquisitive police officer. This behavior, albeit strange, is not sufficiently “criminal” to fall within Drew’s scope.37
It was, therefore, not error for the trial court to rule that the “other” evidence was admissible, without first making a specific finding that it fit within a Drew exception. We affirm the finding, implicit in the trial court’s ruling, that the evidence was circumstantially relevant to show appellant’s identity: simply, that its probative value on this issue outweighed any prejudice to appellant.38
Additionally, we cannot find that appellant was unduly prejudiced by the trial court’s conclusion that Drew did not bar the introduction, under general relevancy principles, of the “other” evidence. Neither attorney made improper use of the evidence during trial. The trial judge cautioned the jury in his charge, using a standard instruction, that evidence relating to each charged offense should be considered separately as to guilt, and that evidence could be viewed cumulatively only to establish identity, common scheme, or motive.39 The record does not support a finding that the trial court abused its discretion. See Grisafi, supra, 383 A.2d at 5-6.
C.
Appellant finally contends that the trial judge erroneously admitted into evidence *771Mrs. M.R.’s statement to Officer Romaine Jenkins. This out-of-court statement, made immediately prior to the complainant’s trial testimony,40 was consistent with her “in-court” explanation for her earlier uncertain identifications of appellant.
The witness testified on direct that she was positive that appellant had attacked her, and that she had been similarly positive at the lineup and before the grand jury. She explained that she feigned uncertainty on the two previous occasions because it was her belief that such uncertainty would keep her from being called to testify at appellant’s trial.41 On cross-examination, appellant’s counsel attempted to establish that the witness knew, prior to her grand jury testimony, that she would have to testify at trial. Because of a language barrier and the imprecision of defense counsel’s queries, there is now disagreement between the parties as to whether Mrs. M.R. did admit that, prior to her grand jury testimony, she knew that she would be called to testify at appellant’s trial42
After the videotape was played for the jury, the government offered testimony of Officer Romaine Jenkins to whom, on the morning her testimony was videotaped, the witness explained the reason for her earlier uncertain identifications of appellant. Appellant contends that the Jenkins’ testimony, which was consistent with complainant’s own explanation, was irrelevant to rehabilitation of the victim’s (allegedly fabricated) taped statement because it was made only hours before. Appellant reasons that, if the complainant had a motive to lie when she testified, then she had the same motive to lie immediately prior to her testimony. We do not accept the logic of this argument.
The trial court found that the complainant’s testimony was sufficiently undercut on cross-examination to allow introduction of the prior consistent statement reflected in Officer Jenkins’ testimony. This finding of impeachment was a necessary precursor to admitting the rehabilitative statement, for an unimpeached witness’ statement may not be bolstered with prior consistent statements. Reed v. United States, 452 A.2d 1173, 1179 (D.C.1982); Johnson v. United States, 434 A.2d 415, 420 (D.C.1981). The Jenkins statement was admitted to rebut defense attorney’s charge of recent fabrication, i.e., that Mrs. M.R. had lied on direct. This was proper. See Reed, supra, 452 A.2d at 1180. We disagree with appellant’s conclusion to the contrary because he cites no motive for Mrs. M.R. to lie to Officer Jenkins. The only specifically alleged motive — avoiding trial testimony— had dissipated by the time the victim spoke to Officer Jenkins. In order to successfully challenge the admission of the Jenkins testimony, appellant had to do more than vaguely allege that the witness had a motive to lie on the day her testimony was given. See United States v. Sampol, 204 U.S.App.D.C. 349, 401, 636 F.2d 621, 673-74 (1980) (quoting other cases). This, he failed to do.
The trial court’s cautionary instructions to the jury were sufficient to insure proper use of the prior statement. No error was made.
There being no other errors complained of, for the foregoing reasons appellant’s convictions are all affirmed.
Affirmed.
