Video: 'KRLD-TV (DALLAS) RAW FOOTAGE: LEE HARVEY OSWALD IS SHOT! (NOVEMBER 24, 1963)'

(Sunday, November 24, 1963, 11:21 a.m. CST) — Lee Harvey Oswald, 24, charged with assassinating President John F. Kennedy, was mortally wounded this morning at the Police and Courts Building in downtown Dallas, Texas, in full view of millions of people watching on television.

Oswald was shot by local nightclub operator Jack Ruby, who emerged suddenly from the crowd of newsmen and policemen witnessing Oswald’s transfer to the county jail and fired his .38 revolver once.

Because his imminent transfer from the police department to the Dallas County jail was being covered on live television by all of the U.S. broadcast networks, millions of viewers were watching as Ruby shot Oswald in the abdomen, at point blank range, with a .38 caliber revolver.

Oswald was rushed unconscious to Parkland Memorial Hospital, the same hospital where doctors tried to save President Kennedy’s life two days earlier. He was taken into surgery but died at 1:07 p.m., never to face trial.

When Ruby was arrested immediately after the shooting, he told several witnesses that he helped the city of Dallas “redeem” itself in the eyes of the public, and that Oswald’s death would spare “…Mrs. Kennedy the discomfiture of coming back to trial.”

Ruby would be convicted of Oswald’s murder, though the decision was overturned on appeal, and Ruby died in prison in 1967 while awaiting a new trial.

After a 10-month investigation, the Warren Commission concluded that Oswald assassinated Kennedy, that Oswald acted entirely alone, and that Ruby acted alone in killing Oswald.

Subsequent federal investigations — such as the Rockefeller Commission and Church Committee — agreed with the Warren Commission’s general findings.
