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 trout 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.

In the corner house itself, Mrs. Barbara Jeanette Davis and her sister-in-law, Mrs. Virginia Davis, heard the shots and rushed to the door in time to see the man walk rapidly across the lawn shaking a revolver as if be were emptying it of cartridge cases. Later that day each woman found a cartridge case near the home. As the gunman turned the corner he passed alongside a taxicab which was parked on Patton Avenue a few feet from 10th Street. The driver, William W. Scoggins, had seen the slaying and was now crouched behind his cab on the street side. As the gunman cut through the shrubbery on the lawn, Scoggins looked up and saw the man approximately 12 feet away. In his hand was a pistol and he muttered words which sounded to Scoggins like "poor dumb cop" or "poor damn cop."

After passing Scoggins, the gunman crossed to the West side or Patton Avenue and ran south toward Jefferson Boulevard, a main Oak Cliff thoroughfare. On the east side of Patton, between l0th Street and Jefferson Boulevard, Ted Callaway, a used car salesman, heard the shots and ran to the sidewalk. As the man with the gun rushed past, Callaway shouted "What's going on?" The man merely shrugged, ran on to Jefferson Boulevard and turned right. On the next corner was a gas station with a parking lot in the rear. The assailant ran into the lot, discarded his jacket and then continued his flight west on Jefferson.

In a shoe store a few blocks farther west on Jefferson, the manager, Johnny Calvin Brewer, heard the siren of a police car moments after the radio in his store announced the shooting of the police officer in Oak Cliff. Brewer saw a man step quickly into the entranceway of the
