A Conyers man convicted of shooting and killing his neighbor may be given a new trial if a civil jury finds he was mentally unfit at the time of his conviction. A civil jury has been granted to Bobby Frank Gordon, 58, who was convicted of murder in August 2009, to determine if Gordon was mentally competent at the time of his trial. Retired Superior Court Judge Sidney Nation, who had heard the original 2009 case and sentenced Gordon to life plus five years, temporarily took the bench again Tuesday to hear the new motion.
