A jury found Jerome Granville guilty of obstruction of an officer, interfering with government property, public drunkenness, and aggravated assault. Following the denial of his amended motion for new trial, Granville appeals. In addition to challenging the sufficiency of the evidence, Granville contends that the trial court failed to warn him of the dangers and disadvantages of proceeding pro se and failed to determine whether he was mentally competent to represent himself. Finding no reversible error, we affirm. 1. Granville first contends that the evidence was insufficient to sustain his convictions. On appeal, the evidence must be viewed in the light most favorable to support the verdict, and Granville no longer enjoys the presumption of innocence. Short v. State , 234 Ga. App. 633, 634 1 507 SE2d 514 1998. We do not weigh the evidence or determine witness credibility, but only determine if the evidence was sufficient for a rational trier of fact to find Granville guilty of the charged offense beyond a reasonable doubt under the standard of Jackson v. Virginia , 443 U. S. 307 99 SC 2781, 61 LE2d 560 1979. Id.
Viewed in the light most favorable to the verdict, the evidence showed that the victim noticed Granville’s grandmother walking along a road in the dark and stopped to give her a ride home. When the victim pulled his car over, Granville, while standing outside the victim’s car, pointed a gun at the victim and said “Stop. Give me and my grandma a ride home.” The victim told Granville that he could not get into his car with a gun and that if Granville would put the gun down, he would take them wherever they needed to go. As Granville and his grandmother got into the victim’s car, police officers arrived. The officers had received information that “someone was walking around with a gun, threatening to shoot people.” One of the officers observed Granville in the back seat of the victim’s car and a gun with its hammer cocked back lying on the floor at Granville’s feet. The officers asked Granville to get out of the car, but he refused. As the officers assisted Granville out of the victim’s car, they noticed the strong odor of alcohol coming from Granville’s person. They opined that Granville was under the influence of alcohol or drugs. One of the officers attempted to handcuff Granville but had to be assisted by a second officer because Granville resisted and became belligerent. The officers managed to place him in the back of a patrol car, where he kicked out two rear windows resulting in over $2,000 in damage. When an officer opened the door of the patrol car, Granville flailed and kicked his legs. The officer then pepper sprayed Granville and put leg chains on him to prevent him from hurting himself or the officers.
