Hill received awards and was promoted for actions that day but for decades blamed himself for then president’s death

Clint Hill, the Secret Service agent who leapt on to the back of John F Kennedy’s limousine after the then president was shot, then was forced to retire early because he remained haunted by memories of the assassination, died on Friday. He was 93.

Hill died at home in Belvedere, California, according to his publisher, Gallery Books, an imprint of Simon & Schuster. A cause of death was not given.
