On 22nd November, 1963, President John F. It was decided that Kennedy and his party, including his wife, Jackie Kennedy, Vice President Lyndon B. Johnson, Governor John Connally and Senator Ralph Yarborough, would travel in a procession of cars through the business district of Dallas. A pilot car and several motorcycles rode ahead of the presidential limousine. As well as Kennedy the limousine included his wife, John Connally, his wife Nellie, Roy Kellerman, head of the Secret Service at the White House and the driver, William Greer. The next car carried eight Secret Service Agents. This was followed by a car containing Lyndon Johnson and Ralph Yarborough. At about 12.30 p.m. the presidential limousine entered Elm Street. Soon afterwards a shot was fired. Secret Service agent Roy Kellerman said to the driver, William Greer, "Let's get out of here." However, Greer hits the breaks. More bullets were fired and John F. Kennedy was hit by bullets that hit him in the head and the left shoulder. Another bullet hit John Connally in the back. At this point Jackie Kennedy crawled onto the trunk of the limousine. At the same time Secret Service agent Clint Hill, runs forward from the car behind. As he reaches the limousine he heard her say: "I have a piece of his brain in my hand." Hill managed to get onto the trunk and shove her back into the car, placing his body over hers and the Presidents and 10 seconds after the first shots had been fired the president's car accelerated off at high speed towards Parkland Memorial Hospital. Both men were carried into separate emergency rooms. Connally had wounds to his back, chest, wrist and thigh. Kennedy's injuries were far more serious. He had a massive wound to the head and at 1 p.m. he was declared dead. Witnesses at the scene of the assassination claimed they had seen shots being fired from behind a wooden fence on the Grassy Knoll and from the Texas School Book Depository.
