Seconds later shots resounded in rapid succession. The President’s hands moved to his neck. He appeared to stiffen momentarily and lurch slightly forward in his seat. A bullet had entered the base of the back of his neck slightly to the right of the spine. It traveled downward and exited from the front of the neck, causing a nick in the left lower portion of the knot in the President’s necktie. Before the shooting started, Governor Connally had been facing toward the crowd on the right. He started to turn toward the left and suddenly felt a blow on his back. The Governor had been hit by a bullet which entered at the extreme right side of his back at a point below his right armpit. The bullet traveled through his chest in a downward and forward direction, exited below his right nipple, passed through his right wrist which had been in his lap, and then caused a wound to his left thigh. The force of the bullet’s impact appeared to spin the Governor to his right, and Mrs. Connally pulled him down into her lap. Another bullet then struck President Kennedy in the rear portion of his head, causing a massive and fatal wound. The President fell to the left into Mrs. Kennedy’s lap. Secret Service Agent Clinton J. Hill, riding on the left running board of the “followup” car, heard a noise which sounded like a firecracker and saw the President suddenly lean forward and to the left. Hill jumped off the car and raced toward the President’s limousine. In the front seat of the Vice-Presidential car, Agent Youngblood heard an explosion and noticed unusual movements in the crowd. He vaulted into the rear seat and sat on the Vice President in order to protect him. At the same time Agent Kellerman in the front seat of the Presidential limousine turned to observe the President. Seeing that the President was struck, Kellerman instructed the driver, “Let’s get out of here; we are hit.” He radioed ahead to the lead car, “Get us to the hospital immediately.” Agent Greer immediately accelerated the Presidential car. As it gained speed, Agent Hill managed to pull himself onto the back of the car where Mrs. Kennedy had climbed. Hill pushed her back into the rear seat and shielded the stricken President and Mrs. Kennedy as the President’s car proceeded at high speed to Parkland Memorial Hospital, 4 miles away.
