Defendant contends that the trial court committed prejudicial and reversible error in admitting evidence of alleged identification of defendant from fingerprints and photographs taken while defendant was allegedly illegally detained. Defendant also contends that identification of defendant by witnesses for the State in the hallway of the police station during illegal detention deprived defendant of his constitutional rights of due process, and admission into evidence of such identification constituted reversible error.
At the conclusion of voir dire examination with respect to the circumstances surrounding the arrest of defendant, the trial judge found that defendant voluntarily accompanied the police to the police station; that defendant allowed himself to be fingerprinted and photographed while in detention; that defendant was identified in the hallway of the police station and by his photograph taken while in detention; and that defendant agreed to go to Hickory where a warrant for his arrest would be served on him for armed robbery. The trial judge concluded that the in-court identification of defendant by State’s witnesses was not tainted by any outside confrontation but was based upon the identification made from observations during the course of the robberies.
*513 [1, 2] Findings of the trial court upon voir dire are binding on appeal when supported by competent evidence. State v. Wingard, 9 N.C. App. 719, 177 S.E. 2d 330. There was plenary competent evidence to support the trial judge’s findings of fact, and the findings justify the conclusion that there was no illegal detention of defendant. The witnesses’ in-court identification was not tainted by any outside confrontation but was of independent origin. This assignment of error is overruled.
[3] Defendant contends that the trial court committed prejudicial error in allowing the State’s expert witnesses on the lifting and comparison of fingerprints to state their opinions before the State had laid a proper foundation for the admission of such evidence. Specifically, the defendant initially contends that the testimony of Captain O. M. McQuire should have been stricken because of the failure of the trial court to have him qualified as an expert in “lifting” fingerprints. The testimony of Captain McQuire disclosed no opinion or intimation as to whose fingerprints were lifted. It merely described the method used in lifting the prints. This assignment of error is overruled.
[4] Defendant also argues that the trial judge committed prejudicial error in allowing State’s witness Stephen R. Jones to testify as to the comparison of the latent fingerprints submitted by Captain McQuire with the fingerprints of defendant on the fingerprint card taken while defendant was in detention. Defendant does not challenge Jones as an expert witness but rather contends that the State failed to lay a proper foundation for the introduction of this evidence by failing to show a proper “chain of custody.”
The sequence of events constituting the chain of custody shows that Captain McQuire “lifted” the latent prints and placed them on letterhead stationery from Capitol Credit. The stationery was then sent along with a fingerprint card of defendant’s fingerprints to the State Bureau of Investigation in a sealed envelope, first class mail. The envelope was received, unopened, by Jones when his secretary carried the envelope from the S.B.I. mailroom to his desk. Jones then opened the envelope with a letter opener. Jones took the materials within, ran his comparison tests, and concluded that latent prints on the stationery and prints on the fingerprint card were identical.
We fail to see how the chain of custody was broken. This assignment of error is overruled.
*514 [5] Defendant contends that the failure of the trial court to instruct the jury on the affirmative defense of alibi constituted prejudicial error. The recent case of State v. Hunt, 283 N.C. 617, 197 S.E. 2d 513 (1973), holds that the trial court is required to give an instruction as to alibi only when requested by defendant. This decision changes the old law that the trial judge must instruct the jury on the defense of alibi, even absent a request by defendant for such instruction. The Hunt decision, swpra, was rendered on 12 July 1973. The instant case went to trial on 17 July 1973. The earlier date of the two advance sheets containing Hunt, supra, is dated 16 August 1973.
Even if we should concede, which we do not, that defendant does not fall under the scope of Hunt, supra, because of the lapse between the time the decision was rendered and the first report in the advance sheets, we cannot agree with defendant’s contention. The record of the trial reveals that the trial judge, in recapitulating testimony, twice stated alibis proffered on behalf of the defendant. Although the desired form of pattern instruction on the defense of alibi was not offered, in substance, defendant twice received the benefit of the instruction that witnesses testified that he was not at the scene of the robbery on the date and time in question but was elsewhere, and could not, therefore, have committed the act, alone or in concert. This assignment of error is overruled.
For the reasons stated, we find the defendant had a fair trial, free from prejudicial error.
No error.
Judges Morris and Carson concur.
