J. D. Tippit (September 18, 1924 – November 22, 1963) was an American police officer who served as an 11-year veteran with the Dallas Police Department. About 45 minutes after the assassination of United States President John F. Kennedy on November 22, 1963, Tippit was shot and killed in a residential neighborhood in the Oak Cliff section of Dallas, Texas. Lee Harvey Oswald was initially arrested for the murder of Tippit and was subsequently arrested for killing President Kennedy. Oswald was charged with both crimes shortly after his arrest but was killed by Jack Ruby two days later.
