J. D. Tippit (September 18, 1924 – November 22, 1963) was an American World War II U.S. Army veteran and Bronze Star recipient, who was a police officer with the Dallas Police Department from 1952 to 1963. On November 22, 1963, less than an hour after the assassination of president John F. Kennedy, 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 charged with killing Kennedy, but he was murdered by Jack Ruby, a Dallas nightclub owner, two days later, before he could be tried. In 1964, the Warren Commission concluded that Tippit was killed by Oswald acting alone, though Tippit's murder has spawned alternative scenarios from Kennedy assassination conspiracy theorists.
