Approximately 14 minutes later, and just 45 minutes after the assassination, another violent shooting occurred in Dallas. The victim was Patrolman J. D. Tippit of the Dallas police, an officer with a good record during his more than 11 years with the police force. He was shot near the intersection of 10th Street and Patton Avenue, about nine-tenths of a mile from Oswald’s roominghouse. At the time of the assassination, Tippit was alone in his patrol car, the routine practice for most police patrol cars at this time of day. He had been ordered by radio at 12:45 p.m. to proceed to the central Oak Cliff area as part of a concentration of patrol car activity around the center of the city following the assassination. At 12:54 Tippit radioed that he had moved as directed and would be available for any emergency. By this time the police radio had broadcast several messages alerting the police to the suspect described by Brennan at the scene of the assassination--a slender white male, about 30 years old, 5 feet 10 inches and weighing about 165 pounds. At approximately 1:15 p.m., Tippit was driving slowly in an easterly direction on East 10th Street in Oak Cliff. About 100 feet past the intersection of 10th Street and Patton Avenue, Tippit pulled up alongside a man walking in the same direction. The man met the general description of the suspect wanted in connection with the assassination. He walked over to Tippit’s car, rested his arms on the door on the right-hand side of the car, and apparently exchanged words with Tippit through the window. Tippit opened the door on the left side and started to walk around the front of his car. As he reached the front wheel on the driver’s side, the man on the sidewalk drew a revolver and fired several shots in rapid succession, hitting Tippit four times and killing him instantly. An automobile repairman, Domingo Benavides, heard the shots and stopped his pickup truck on the opposite side of the street about 25 feet in front of Tippit’s car. He observed the gunman start back toward Patton Avenue, removing the empty cartridge cases from the gun as he went. Benavides rushed to Tippit’s side. The patrolman, apparently dead, was lying on his revolver, which was out of its holster. Benavides promptly reported the shooting to police headquarters over the radio in Tippit’s car. The message was received shortly after 1:16 p.m. As the gunman left the scene, he walked hurriedly back toward Patton Avenue and turned left, heading south. Standing on the northwest corner of 10th Street and Patton Avenue was Helen Markham, who had been walking south on Patton Avenue and had seen both the killer and Tippit cross the intersection in front of her as she waited on the curb for traffic to pass. She witnessed the shooting and then saw the man with a gun in his hand walk back toward the corner and cut across the lawn of the corner house as he started south on Patton Avenue.
