I

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 their 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. A short time late the four men interrupted their journey for a rest stop along the highway. The next morning the bodies of Simmons and Moore were discovered in a ditch nearby.

On November 23, after reading about the shootings in an Atlanta newspaper, Weaver communicated with the Gwinnett County police and related information concerning the journey with the victims, including a description of the car. The next afternoon, the petitioner and Allen, while in Simmons' car, were arrested in Asheville, N. C. In the search incident to the arrest a .25-caliber pistol, later shown to be that used to kill Simmons and Moore, was found in the petitioner's pocket. After receiving the warnings required by Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966), and signing a written waiver of his rights, the petitioner signed a statement in which he admitted shooting, then robbing Simmons and Moore. He justified the slayings on grounds of self-defense. The next day, while being transferred to Lawrenceville, Ga., the petitioner and Allen were taken to the scene of the shootings. Upon arriving there, Allen recounted the events leading to the slayings. His version of these events was as follows: After Simmons and Moore left the car, the petitioner stated that he intended to rob them. The petitioner then took his pistol in hand and positioned himself on the car to improve his aim. As Simmons and Moore came up an embankment toward the car, the petitioner fired three shots and the two men fell near a ditch. The petitioner, at close range, then fired a shot into a head of each. He robbed them of valuables and drove away with Allen.

A medical examiner testified that Simmons died from a bullet wound in the eye and that Moore died from bullet wounds in the cheek and in the back of the head. He further testified that both men had several bruises and abrasions about the face and head which probably were sustained either from the fall into the ditch or from being dragged or pushed along the embankment. Although Allen did not testify, a police detective recounted the substance of Allen's statements about the slayings and indicated that directly after Allen had made these statements the petitioner had admitted that Allen's account was accurate. The petitioner testified in his own defense. He confirmed that Allen had made the statements described by the detective, but denied their truth or ever having admitted to their accuracy. He indicted that he had shot Simmons and Moore because of fear and in self-defense, testifying they had attacked Allen and him, one wielding a pipe and the other a knife.
