Agent Clint Hill testified that he heard one shot, then jumped off the running board of the Secret Service follow-up car directly behind Kennedy (Hill was filmed jumping off his follow-up car at the equivalent of Zapruder frame 308; about a quarter of a second before the president's head exploded at frame 313). Hill then rapidly ran towards the Presidential limo and then another shot hit Kennedy in the head, cracking open the right side of his skull. As the limousine began speeding up, Mrs. Kennedy was heard to scream and she climbed out of the back seat onto the rear of the limo. At the same time, Hill managed to climb aboard and hang onto the suddenly accelerating limo, and Mrs. Kennedy returned to the back seat. Hill then shielded her and the President. Both of the Connallys stated they heard Mrs. Kennedy say, "I have his brains in my hand!" The limo driver and police motorcycles turned on their sirens and raced at high speeds to Parkland Hospital, passing their intended destination of the Dallas Trade Mart along the way, and arriving at about 12:38 p.m. (CST). Governor Connally was also struck by the shots, and his wife pulled him closer to her. He suffered several severe wounds that he survived; a bullet entry wound in his upper right back located just behind his right armpit; four inches of his right, fifth chest rib was pulverised; a two-and-a-half inch sized chest exit wound; his right arm's wrist bone was fractured into seven pieces; and he had a bullet entry wound in his left inner thigh. Although there is controversy about exactly when he was wounded, analysts from both the Warren Commission (1964) and House Select Committee on Assassinations (1979) believed that his wounds had been inflicted nearly simultaneously with President Kennedy's in their theories that the two men were struck by a single bullet. The Commission theorized both men were hit nearly simultaneously between Zapruder film frames 210 to 225, while the Committee theorized it happened at frame 190. Witness James Tague was also injured by the shots when he received a superficial face wound. The Main Street south curb he had been standing 23.5 feet away from was struck by a bullet or bullet fragment that had no copper sheath, and a fragment of the concrete curb or a bullet fragment struck Tague on his right cheek.
