On November 22, 1963, John F. Kennedy went on a 10-mile motorcade down the streets of Dallas with his wife, Jaqueline Kennedy, and Texas Governor John Connaly who bought his wife. As they passed the Texas school book depository building in a Lincoln convertible, President JFK was struck with three bullets. Connaly was injured as well, but near as close as Kennedy was. Thirty minutes later, Kennedy died. He was 46 years old. Lee Harvey Oswald was the assassin who murdered Kennedy. 2 hours and 9 minutes after Kennedy’s assassination, vice president Lyndon was sworn president of the United States.
When a police officer was questioning Oswald next to his rooming house, Oswald murdered him, but was arrested later on at a movie theatre later on. As the killer of John F. Kennedy walked through the Dallas Police Department, A man named Jack Ruby jumped out of a crowd of reporters and fired a gun at Oswald. Jack Ruby features prominently in the Kennedy-assassination theories. Many people believe he shot Oswald to keep him from revealing a larger conspiracy. During his trial, he claimed he had a psychomotor epilepsy which caused him to shoot Oswald unconsciously. Ruby was found guilty of murder and was sentenced to die. In October 1966, the 
Texas Court of Appeals reversed the decision on the grounds of improper admission of testimony and the fact that Ruby could not have gotten a fair trial in Dallas at the time. In January 1967, while awaiting a new trial, which would have taken place in Wichita Falls, Ruby died of lung cancer in a Dallas hospital.
