STATE of North Carolina
v.
Solomon BROWN.
No. 7621SC32.
Court of Appeals of North Carolina.
May 5, 1976.
Certiorari Denied July 14, 1976.
*194 Atty. Gen. Rufus L. Edmisten by Associate Atty. Norma S. Harrell, Raleigh, for the State.
W. Warren Sparrow, Winston-Salem, for defendant-appellant.
Certiorari Denied by Supreme Court July 14, 1976.
BRITT, Judge.
Defendant's only assignment of error is that the court erred in not requiring the State to disclose the identity of a confidential informant. We find no merit in the assignment.
Evidence presented by the State tended to show: In April of 1975, Martha Owens, an agent of the State Bureau of Investigation, went to Winston-Salem to purchase drugs as an undercover agent. On the afternoon of 17 April she and a female confidential source went to defendant's apartment. The source told defendant that Geraldine (defendant's wife) had sent them to him and that they wanted to buy some heroin. Defendant delivered 15 tinfoil packets to Owens for which she paid him $100.00. Thereafter, an analysis of the contents of the packets revealed the presence of heroin.
Defendant testified that he did not sell heroin on the day in question or at any other time and that he had never seen Agent Owens prior to seeing her in court.
It appears to be well settled that the nondisclosure of an informer's identity must be balanced against the need for effective law enforcement; but where the informer's identity and potential testimony are essential to a fair determination of the case or material to a defendant's defense, the privilege must give way and the informer's name be disclosed if the defendant is to be prosecuted. Roviaro v. United States, 353 U.S. 53, 77 S.Ct. 623, 1 L.Ed.2d 639 (1957); State v. Ketchie, 286 N.C. 387, 211 S.E.2d 207 (1975).
The facts in the instant case are clearly distinguishable from Roviaro and other cases requiring disclosure of the informer's name. Here, the informer had little if any active participation in the actual crimes. The evidence showed that after she told defendant that Geraldine sent them, the informer proceeded to go to and use the bathroom while Agent Owens made the actual purchase from defendant. In Roviaro, for example, the informer made the purchase of drugs while the police officer hid in the trunk of the informer's car and made a tape recording of the transaction.
Furthermore, we do not think defendant made a sufficient showing before the trial court of his need for disclosure of the informer's identity. The record reveals that the only time the question was raised was when Agent Owens was on recross-examination. At that time she was asked, "Who is the source?" The State's objection to the question was sustained. The witness then testified that she did not know the source but she was not an agent; that she met the informer for the first time that afternoon, some hour or so before going to defendant's apartment. Defendant failed to show that the informer's identity and possible testimony were essential to a fair determination of the case or material to his defense. State v. Boles, 246 N.C. 83, 97 S.E.2d 476 (1957), decided subsequent to Roviaro.
We hold that defendant received a fair trial free from prejudicial error.
No error.
VAUGHN and ARNOLD, JJ., concur.
