Murder Or Suicide? Chilling Evidence About Marilyn Monroe's Death Exposed — Why Her Tragic Case Could Be Cracked Open Again

Marilyn Monroe was one of Hollywood's most beautiful, but the actress' life was full of secrets — and even darker secrets about some of the most powerful men in the world who she had sex romps with. So when she turned up dead at 36 in 1962, the world only began to learn about Marilyn's secret off-screen life.

So there's no surprise that her tragic death continues to raise the troubling question — did she really commit suicide or was she murdered?

Marilyn's husband, Joe DiMaggio, never healed over the loss of her — even up until his dying day back in March 1999. But a source revealed to RadarOnline that Joe was known for calling a couple of Marilyn's sex partners some nasty names — Frank Sinatra as "The Pimp" and Bobby Kennedy as "The Murderer."

According to FBI documents, Robert Kennedy was caught at the actress' house before she died — but his motive for visiting had ill reasons. The presidential brother was trying to reason with Marilyn about keeping their affairs quiet. When she refused, a suicide was staged by Kennedy and his cronies, plus Kennedy's brother-in-law, Peter Lawford, who allegedly directed the cover-up scene.

Another report claims that Marilyn could have been murdered by another man she trusted, her psychiatrist Dr. Ralph Greenson. Marilyn's housekeeper Eunice Murray told author George Carpozi that she witnessed the shrink giving her an "anal injection." The dark play could have been orchestrated by Bobby Kennedy who threatened Dr. Ralph's career if he didn't "finish off" the actress. But the first injection didn't do the job, so Dr. Ralph injected another syringe into Marilyn's heart, ambulance attendant James Hall told Jay Margolis.
