Marilyn Monroe
The world was shaken on August 5, 1962, when Marilyn Monroe was found dead at 36 in her home in Los Angeles. The cause? A barbiturate overdose that was ruled a probable suicide.
That lead many to doubt the gorgeous star, rumored to have been involved in extramarital affairs with both John F. Kennedy and his brother, Robert F. Kennedy, had taken her own life. Instead, conspiracy theorists have long been suspected Monroe was murdered to keep her from talking about the Kennedy brothers. The CIA continues to maintain files on Monroe’s death, and it is unlikely anyone will ever know what really happened.
