John Fitzgerald Kennedy
The 35th President Of The United States

Born: May 29, 1917
Assassinated: November 22, 1963

Note that JFK's head moves forward first.
This is from the impact of a bullet that hits JFK in the back
of the head. A split second later, the head moves violently
up and then back and to the left from the impact of another
bullet fired from the front [sewer drain] into his right temple.
