Some 50 years after her death, Norma Jeane Mortenson remains one of the most iconic and well-loved movie stars ever to have graced the big screen. However, while her legacy with live on thanks to her roles in the likes of the Seven-Year Itch and Some Like it Hot, the fact she was one of the biggest stars of her time, and her status as a beauty icon, there's also another reason she remains a popular figure for discussion: her death, back in 1962, at just 36-years-of-age. She was found dead in her California home, in bed with an empty bottle of sleeping pills in her hand, so it seemed a foregone conclusion that she had committed suicide, and indeed that was the official ruling. She'd allegedly been suffering from depression, so it seemed to fit that was what happened. There are many who refuse to believe that was the case though, and have pointed to some mysterious circumstances before her death. A number of items were apparently taken from her apartment, including a personal diary and a note that could have major implications for the White House. Theories have included that she was murdered by the mafia, or that her death was a government-ordered assassination due to her supposed affairs with John F. and Robert Kennedy. It was later discovered that FBI files on the case had gone missing, and still haven't been recovered to this day, further fuelling speculation she was killed.
