what happened to jack ruby

Jack Ruby died of cancer complications while in custody, after his conviction for killing Lee Harvey Oswald had been overturned and a new trial was pending.

Quick Scoop: What Happened to Jack Ruby?

1. Who Jack Ruby Was

• Jack Ruby (born Jacob Rubenstein in 1911) was a Chicago native who later ran nightclubs and strip clubs in Dallas, notably the Carousel Club.

• He had a reputation for a volatile temper, attention‑seeking behavior, and casual ties to local law enforcement, often socializing with officers at his clubs.

2. The Oswald Shooting

• On November 24, 1963—two days after President John F. Kennedy was assassinated—Ruby stepped out of a crowd in the basement of Dallas Police Headquarters and shot Lee Harvey Oswald on live television.

• Oswald was hit in the abdomen, suffered massive internal injuries, and died shortly after at Parkland Memorial Hospital, the same hospital where Kennedy had died.

3. Trial, Conviction, and Appeal

• Ruby was immediately arrested and charged with murder; Dallas DA Henry Wade publicly said he would seek the death penalty, calling Oswald’s killing a “second assassination.”

• At his 1964 trial, Ruby’s defense argued he acted under extreme emotional disturbance and even raised “psychomotor epilepsy” as a theory to explain his actions, but the jury convicted him of murder with malice and sentenced him to death.

• In 1966, an appeals court overturned his conviction and death sentence due to procedural issues, including problems with jury selection and pretrial publicity, and ordered a new trial in another Texas city.

4. Illness and Death

• While awaiting this new trial, Ruby’s health rapidly declined; doctors found he had advanced lung cancer that had spread to other parts of his body.

• On January 3, 1967, at age 55, he died at Parkland Memorial Hospital from a pulmonary embolism and complications related to lung cancer; some sources emphasize pneumonia secondary to the cancer, others the fatal blood clot.

• Because he died before the retrial, his original conviction had been overturned, leading his attorney to note that, technically, “Jack died not a convicted man.”

5. Burial and Aftermath

• Ruby’s body was flown to Chicago and buried in Westlawn Cemetery, in the same cemetery and family plot as his parents, in accordance with Jewish burial traditions.

• He never married and left no children.

6. Motive and Conspiracy Theories

• Ruby publicly insisted he acted alone and out of grief and anger over Kennedy’s death, claiming he wanted to spare Jacqueline Kennedy the ordeal of seeing Oswald on trial.

• The Warren Commission concluded Ruby was not part of a broader conspiracy, though theories tying him to organized crime or shadowy plots have persisted for decades and remain a staple of forum and documentary debate.

• People who knew him, including Dallas reporters, often argued he was too impulsive and talkative to be trusted in any sophisticated conspiracy, which has become a key counterpoint in discussions of his role.

In modern forum and “what really happened” discussions, Jack Ruby is usually portrayed as either a tragic, hot‑headed nightclub owner who acted on impulse—or a possible puzzle piece in the unresolved questions surrounding the JFK era.

TL;DR:
Jack Ruby, a Dallas nightclub owner, shot Lee Harvey Oswald on live TV in 1963, was sentenced to death, won a new trial on appeal, then died of lung cancer complications at Parkland Hospital in January 1967 before that second trial could happen.
