Emmanuel Wallace was convicted by a jury of two counts of sale of marijuana, one count of armed robbery, and one count of possession of a knife during the commission of a felony. Following the denial of his motion for new trial, Wallace appeals, challenging the sufficiency of the evidence and portions of the trial court’s charge. We find no reversible error, and we affirm. 1. We first address Wallace’s contention that the evidence was insufficient to convict him of armed robbery and possession of a knife during the commission of a felony. He argues that the State failed to prove that he used a knife during the robbery. Construed in favor of the verdict, evidence was presented that Gwinnett County Police Department investigator David Borgan made two controlled marijuana buys from Wallace during the summer of 1998. They arranged for a third sale, to take place on November 5, 1998. After Borgan arrived at the designated location for the transaction, he observed Wallace’s vehicle arrive, carrying Wallace and two other men. Wallace exited the vehicle, retrieved a small box from the rear of the car, and began walking toward Borgan’s vehicle. At that time, Borgan heard the other car “start back up.”
Wallace entered Borgan’s vehicle and tossed the box to Borgan. Borgan testified that he “picked up the box” and “realized that it was empty, and by the time I could do anything, that’s when the knife was up to my throat.” Borgan saw the blade of the knife and part of the handle. He described it as “a lock-blade knife” having a handle made of brass and wood. He believed the length of the blade was three inches or more. Holding the knife against Borgan, Wallace demanded money from him. Borgan told him where to find the money, and Wallace took it and Borgan’s keys from the vehicle. As Wallace left the car, Borgan retrieved his own gun and yelled, “Police. Stop. Don’t move. Stop. Police.” Wallace jumped into his own car, and the vehicle left the scene. Wallace was apprehended a short time later.
