https://www.jfk-assassination.net/russ/testimony/hill_c.htm Testimony of Clinton J. Hill, Special Agent Secret Service Mr. Specter - What did you observe as to Presidents Kennedy's condition on arrival at the hospital?
Mr. Hill - The right rear portion of his head was missing . It was lying in the rear seat of the car . His brain was exposed . There was blood and bits of brain all over the entire rear portion of the car . Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not , except for the " LARGE GAPING WOUND IN THE RIGHT REAR PORTION OF OF THE HEAD .
Hill's description of the head never made much sense to me. Within that same testimony, he said that Kennedy was "lying face up" in Mrs. Kennedy's lap. How can he see a hole in the back of Kennedy's head when he's lying face up? Mrs. Kennedy cradled his head. In all the pictures taken on the way to Parkland, Mrs. Kennedy is out of view because she's bent over her husband while cradling his head. Hill is still on the rear of the car as the limousine enters the underpass, while Mrs. Kennedy has sunken down into the seat compartment after she toppled back in place. Several factors play into the location of the missing skull. Mrs. Kennedy said--7 days after the assassintion--that the TOP of his head was gone when interviewed by Theodore White.
"I was trying to hold the top of his head down. Maybe I could keep it(the brain) in" She repeated this once more to White. The Nix, Muchmore and Zapruder film all three show the same, exact things: The top of his head flying through the air. The Mary Ann Moorman Krahmer photograpgh shows the top of his head gone, In two of the rare times Charles Brehm described the fatal shot, he said he saw the top of JFK's head fly off. He said this to Larry Sneed, and he said it in Dealey Plaza on video during the 30th anniversary. The autopsy photos of the top of the head show a massive hole on top of the head. By the time JFK entered Parkland Hospital, Mrs. Kennedy had closed up the wound as much as possible, by putting the large flap of skull hanging down in front of JFK's right ear back into place. Clearly, it was the top-not the side or rear-of JFK's head that was shot off.
