John F. Kennedy was shot once in the back and once in head while riding with his wife Jacqueline in a Presidential motorcade through the streets of Dallas, Texas on November 22, 1963. Lee Harvey Oswald was arrested 45 minutes after the shots were fired. After hours of interrogation, in which none of the proper procedures were followed, he was accused of murder. He was killed by Jack Ruby in the garage of the police building on November 24 in front of hundreds of journalists.
On November 29, President Lyndon B. Johnson created the Warren Commission to investigate the assassination. It was headed by Earl Warren, the Chief Justice of the United States, and found that Oswald was the lone shooter and that he did it from the sixth floor of the Schoolbook Depository Building with an Italian Mannlicher-Carcano rifle.
