A Hall County jury convicted Benjamin Herring of sale of cocaine, OCGA § 16-13-30. He appeals from the denial of his motion for new trial, contending the evidence was insufficient to support his conviction, and that the trial court improperly limited his cross-examination of a witness. Finding no error, we affirm. 1. Herring challenges the sufficiency of the evidence, particularly the credibility of the testimony by the undercover agent who purchased drugs from Herring and an accomplice. On appeal from a criminal conviction, the evidence must be viewed in the light most favorable to the verdict, and the defendant no longer enjoys the presumption of innocence; moreover, an appellate court does not weigh the evidence or determine witness credibility but only determines whether the evidence is sufficient under the standard of Jackson v. Virginia , 443 U. S. 307 99 SC 2781, 61 LE2d 560 1979. Conflicts in the testimony of the witnesses, including the State’s witnesses, are a matter of credibility for the jury to resolve. As long as there is some competent evidence, even though contradicted, to support each fact necessary to make out the State’s case, the jury’s verdict will be upheld. The testimony of a single witness is generally sufficient to establish a fact. Footnote, citation, and punctuation omitted. Arnold v. State , 260 Ga. App. 287, 288 581 SE2d 601 2003.
So viewed, the evidence showed that, on May 7, 1996, Herring went to Eberhart’s Cafe in Hall County. At approximately 2:45 p.m., an agent of the Multi-Agency Narcotics Squad “MANS” drove to the cafe after the MANS received a tip that Aunree Faulkner was selling crack cocaine there. The agent had previously purchased drugs at the cafe while undercover, and he went to the cafe to attempt another undercover purchase of drugs. He was dressed in “rough . . . dirty looking” clothes, and drove an older, unmarked, dented car with his window down, so that it would appear that he wanted to purchase some drugs. As the agent slowly approached the cafe, Aunree Faulkner waved at him to pull into the lot. The agent called out to Faulkner that he was “trying to get hooked up,” in other words, trying to purchase crack cocaine. Faulkner asked the agent if he wanted some dope. The agent responded that he wanted “about forty,” meaning forty dollars worth of crack cocaine. Faulkner told him to “hold on.”
