The petitioner, Troy Gregg, was charged with committing armed robbery and murder. In accordance with Georgia procedure in capital cases, the trial was in two stages, a guilt stage and a sentencing stage. The evidence at the guilt trial established that on November 21, 1973, the petitioner and a traveling companion, Floyd Allen, while hitchhiking north in Florida were picked up by Fred Simmons and Bob Moore. Their car broke down, but they continued north after Simmons purchased another vehicle with some of the cash he was carrying. While still in Florida, they picked up another hitchhiker, Dennis Weaver, who rode with them to Atlanta, where he was let out about 11 p.m.
