Rheakdsy Mike Yat was convicted of felony murder and possession of a firearm during the commission of a felony arising out of the shooting death of Hieu Tran.1 Because we find the evidence was sufficient to support their convictions and no merit in the remaining errors, we affirm. Evidence adduced at trial established that appellant is a member of a gang called “Asian Gangster Crips” “AGC”. On January 9, 2000, as co-indictee Vandara Ros dined at a Gwinnett County restaurant, he spotted members of a rival gang, the “Insane Gangster Pirates” “IGP”, who were also at the restaurant. The victim, Hieu Tran, was a college student not affiliated with either gang but he was in the restaurant with his two brothers, who were with IGP. Ros telephoned other AGC members and instructed them to get their guns and come to the restaurant. Appellant and co-indictee Albert Kim Tran no relation to the victim were among the three carloads of AGC members who responded. Appellant, Ros, Tran and the other AGC gang members ambushed the victim and the IGP members as they were leaving the restaurant. Ros, knocked to the ground by the victim, fired a .9 millimeter handgun twice without hitting anyone before fleeing the scene. After Tran’s attack with a miniature baseball bat left the victim sprawled on the sidewalk, appellant shot the victim twice in the back with a .38 caliber pistol he had earlier helped to hide in a dumpster behind the restaurant. Two witnesses from the AGC gang testified they saw appellant actually firing the gun, although they could not see the victim. Later that evening appellant admitted to another gang member that he shot the victim twice, claiming he did so in the chest rather than in the back. The .38 pistol was later recovered by police from appellant’s backyard and expert testimony established that it fired the shots that inflicted the victim’s fatal injuries.2
1. Appellant contends that the trial court erred by failing to grant his motion for a directed verdict because the biased testimony of other gang members and the weak circumstantial evidence was insufficient to warrant a conviction for felony murder. However, the credibility of the witnesses was a determination to be made by the jury, including whether the deals made by other gang members with the State rendered their testimony biased to a degree that left them less creditworthy. See generally Brown v. State , 277 Ga. 53 1 586 SE2d 323 2003; State v. Vogleson , 275 Ga. 637 1 571 SE2d 752 2002. The evidence adduced was sufficient to authorize a rational trier of fact to find beyond a reasonable doubt that appellant was guilty of felony murder and the firearm possession charge. Jackson v. Virginia , 443 U.S. 307 99 SC 2781, 61 LE2d 560 1979. Accordingly, the trial court did not err by denying appellant’s motion for a directed verdict. Dorsey v. State , 279 Ga. 534 3 SE2d 2005 standard for reviewing denial of motion for directed verdict of acquittal is same test used for sufficiency of the evidence, i.e., Jackson v. Virginia , supra.
