Two other important eyewitnesses to Oswald’s flight were Ted Callaway, manager of a used-car lot on the northeast corner of Patton Avenue and Jefferson Boulevard, and Sam Guinyard, a porter at the lot. They heard the sound of shots to the north of their lot.[C4-546] Callaway heard five shots, and Guinyard three. Both ran to the sidewalk on the east side of Patton at a point about a half a block south of 10th. They saw a man coming south on Patton with a revolver held high in his right hand. According to Callaway, the man crossed to the west side of Patton.[C4-547] From across the street Callaway yelled, “Hey, man, what the hell is going on?” He slowed down, halted, said something, and then kept on going to the corner, turned right, and continued west on Jefferson.[C4-548] Guinyard claimed that the man ran down the east side of Patton and passed within 10 feet of him before crossing to the other side.[C4-549] Guinyard and Callaway ran to 10th and Patton and found Tippit lying in the street beside his car.[C4-550] Apparently he had reached for his gun; it lay beneath him outside of the holster. Callaway picked up the gun.[C4-551] He and Scoggins attempted to chase down the gunman in Scoggin’s taxicab,[C4-552] but he had disappeared. Early in the evening of November 22, Guinyard and Callaway viewed the same lineup of four men from which Mrs. Markham had earlier made her identification of Lee Harvey Oswald. Both men picked Oswald as the man who had run south on Patton with a gun in his hand.[C4-553] Callaway told the Commission: “So they brought four men in. I stepped to the back of the room, so I could kind of see him from the same distance which I had seen him before. And when he came out I knew him.”[C4-554] Guinyard said, “I told them that was him right there. I pointed him out right there.”[C4-555] Both Callaway and Guinyard testified that they had not been shown any pictures by the police before the lineup.[C4-556] The Dallas Police Department furnished the Commission with pictures of the men who appeared in the lineups with Oswald,[C4-557] and the Commission has inquired into general lineup procedures used by the Dallas police as well as the specific procedures in the lineups involving Oswald.[C4-558] The Commission is satisfied that the lineups were conducted fairly.
