None of the defendant’s many assignments of error relating to his conviction have merit or requires more than passing discussion, and some require no discussion.
[1] The defendant’s most earnest contention is that the victim’s testimony that defendant told her that if she tried to escape from his control she would end up like “the last white girl” did was in*429admissible because it tended to show only that he had committed murder and thus was a bad man. The defendant misperceives the impact and effect of the testimony objected to. Not only was the testimony relevant to some essential fact that was in issue, it tended to prove the very heart of the State’s case — that defendant maintained dominion over the witness by putting her in fear for her life — and was thus properly received into evidence, notwithstanding its devastating impact. 1 Brandis N.C. Evidence § 92 (2d ed. 1982).
[2] Another contention is that the court erred in charging the jury that time was not of the essence in this case, the prosecuting witness having contradicted herself as to whether the Jacksonville bus station incident occurred on January 29th, 1982, the date given in the indictment, or on January 22nd, 1982 or January 30th, 1982. The instruction was correct, however, since the rule generally in criminal cases is that time is not of the essence except where an alibi, the statute of limitations, or some other defense predicated on time is involved. State v. Bailey, 49 N.C. App. 377, 271 S.E. 2d 752 (1980), rev. denied, 301 N.C. 723, 276 S.E. 2d 288 (1981).
[3] Defendant also cites the following part of the charge as error:
And, so, I charge that if you find from the evidence, and beyond a reasonable doubt, that on or about January 29, 1982, the defendant unlawfully held Donna Lippard at Circle Drive apartments and not allowing her to leave for three days; or that he beat her all over the body and threatened her and had her watched so as to prevent her from leaving Circle Drive apartments; or that he carried Donna Lippard from the bus station to the Circle Drive apartments and that Donna Lippard did not consent, and that this was for the purpose of terrorizing Donna Lippard by beating her and not allowing her to leave, then it would be your duty to return a verdict of guilty as charged.
The contention is that his activities over the three-day period were not separable, and that instead of instructing the jury in the disjunctive, the court should have told the jury that to convict him it would be necessary to find that he did all the intimidating acts and made all the threatening remarks referred to. But the *430court was just following the statute that defendant was being tried under, G.S. 14-39, which provides, in part, as follows:
(a) Any person who shall unlawfully confine, restrain, or remove from one place to another, any other person 16 years of age or over without the consent of such person . . . shall be guilty of kidnapping if such confinement, restraint or removal is for the purpose of:
(3) Doing serious bodily harm to or terrorizing the person so confined, restrained or removed or any other person.
Thus, in order to convict, the jury did not have to find that defendant unlawfully confined, restrained, and removed the witness, but only that he unlawfully did any of those things either for the purpose of terrorizing or doing serious bodily harm to her.
[4] But the defendant’s contention that error was committed in the sentencing process is well taken. The presumptive sentence for the Class E felony that defendant was convicted of is nine years. G.S. 15A-1340.4(f)(3). The thirty year maximum sentence that was imposed was based on three aggravating factors, only one of which was properly found and authorized by the Fair Sentencing Act. The evidence showed and it was properly found that defendant had prior convictions punishable by confinement of sixty days or more. That the State failed to prove that defendant was not indigent or was represented by or waived counsel when those convictions occurred is immaterial, since under State v. Thompson, 309 N.C. 421, 307 S.E. 2d 156 (1983), it was up to the defendant to show that the proven or admitted convictions were improperly obtained within contemplation of the Act, and defendant attempted no such showing.
The first factor in aggravation that the court improperly found was that defendant had “knowingly devoted himself to criminal activity.” This finding is patently ambiguous, and what the court meant by it, we do not know. If it was meant that defendant knowingly committed the crime he was convicted of, the finding is banned by G.S. 15A-1340.4, since “[e]vidence necessary to prove an element of the offense may not be used to prove any *431factor in aggravation.” If it was meant that defendant knowingly committed the other crimes that are the basis for the first finding, it is banned by the same statute, which also provides “and the same item of evidence may not be used to prove more than one factor in aggravation.” If, however, it was meant that defendant had habitually devoted himself to criminal activity over a long period of time — which was shown by evidence that for several years he had not been lawfully employed and had lived off of money received from gambling and prostitutes — that is not what the finding states, and it cannot be so construed. Whether in addition to a prior conviction factor, G.S. 15A-1340.4 also authorizes under appropriate circumstances finding a factor in aggravation that a defendant regularly and habitually led a life of crime, it is not necessary to say, since such a finding is not before us.
The other finding in aggravation improperly found was that the sentence imposed was “necessary to deter others from committing the same crime.” As has been ruled in several cases, since deterrence, a basic purpose of all sentencing, was necessarily considered by the Legislature in establishing presumptive sentences for the various crimes, it cannot also be the basis for trial judges exceeding the presumptive terms. See State v. Chatman, 308 N.C. 169, 301 S.E. 2d 71 (1983) and cases therein cited.
Because of the aggravating factors erroneously found, the resentencing process must be repeated as required by State v. Ahearn, 307 N.C. 584, 300 S.E. 2d 689 (1983).
Thus, in the defendant’s trial there is no error and this matter is remanded to the Superior Court for resentencing.
No error in trial; remanded for resentencing.
Judges Arnold and Johnson concur.
