Celeb: Marilyn Monroe
Cause Of Death: Possible Suicide
The 36-year-old icon was found dead in her apartment in 1962. Though the autopsy report found a large amount of sleeping pills in her system, it’s been suspected that the Kennedy brothers may be the cause of her untimely death. Allegedly, Monroe had an affair with President John F. Kennedy and his brother Robert Kennedy, both of who were married and didn’t need a celebrity sex symbol tarnishing their image. Some suspect that they paid a hitman to end their relations with Monroe, permanently.
