Jack Ruby was a nightclub owner in Dallas, Texas, who became famous for his role in the assassination of Lee Harvey Oswald, the man accused of killing President John F. Kennedy. On November 24, 1963, just two days after the assassination, Ruby shot Oswald in the basement of the Dallas police headquarters, an act that shocked the nation and was captured on live television.
Ruby's actions led to a highly publicized trial, where he claimed he acted out of grief and anger over Kennedy's death. Ultimately, he was convicted of murder but died of cancer in 1967 while serving his sentence, leaving many questions about his motives and connections unanswered.
