Jack Ruby
Jack Leon Ruby (born Jacob Leon Rubenstein; April 25, 1911 – January 3, 1967) was a Dallas, Texas nightclub owner. He fatally shot Lee Harvey Oswald on November 24, 1963, while Oswald was in police custody after being charged with assassinating United States President John F. Kennedy and murdering Dallas policeman J. D. Tippit about an hour later. A Dallas jury found him guilty of murdering Oswald, and he was sentenced to death. Ruby's conviction was later appealed, and he was granted a new trial. However, on January 3, 1967, as the date for his new trial was being set, Ruby became ill in his prison cell and died of a pulmonary embolism from lung cancer.
