The first conspiracy relating to the Hollywood actress, is that she overdosed on her sleeping pills, purposely taking her own life by an act of suicide. As a young child, she felt unwanted, likely since her own biological mother didn’t keep her (Dorfman 74). Being in and out of foster homes and sexually abused growing up didn’t help either in contributing to her drug addiction (Dorfman 84). In interviews with journalist W.J. Weatherby, she talked about her insomnia, and about taking sleeping pills. Monroe had mentioned suicide: “I tried it once and I was kinda disappointed it didn’t work.” She isolated herself (Dorfman 161). Her doctor, Ralph Greenson, at one point had tried to get her off the ridiculously large number of drugs she was taking out of fear she would overdose and had failed in doing so but, continued to write her prescriptions anyway (Dorfman 124). It's very clear to see that Marilyn battled depression and struggled with addiction throughout her life and this is what ultimately led to her unfortunate demise.  The second conspiracy is that the Kennedy brothers, John and Robert, had her killed because she knew too much information about their plans. Out of fear for his life and from the threat that she would tell their business to the world, Robert Kennedy had her dealt with to protect himself. Journalist, Anthony Scaduto, stated "she had a diary full of incriminating information that she had overheard from the Kennedy's" (Wehn 34). Her infamous red diary contained very detailed conversations she had in private with Robert (Vogel 85). Which, according to Scaduto, caused Robert Kennedy to have her killed to keep her silent (Wehn 32).  He was in the middle of running for the senate when he broke things off with her, but she had threatened to expose it all about his secret plans, because she was hurt by this, so this was certainly not going to be a good look for him. The evening before her death he made a visit to see her and sources say he was one of the last people to see her alive, although his attorney said he was in northern California with his family the entire weekend. He then pushed her drug addiction to the point of “accidental” overdose and covered up her death, thus making it appear to be a suicide. Even the first officer on scene, Sergeant Jack Clemmens, who had been interviewed repeatedly over the years, stated that “Somebody murdered her. It was an in and out case of murder” (Vogel 130). This theory highly suggests that Robert Kennedy and his family had many secrets that they did not want exposed, and knowing that Monroe knew too much information about their personal life, especially that of which was written in her diary, he wanted her permanently out of the picture so he could keep those secrets hidden from the rest of the world. Leaving the world to ponder if he is truly responsible for her death.

 While her death is most certainly a tragic one, there are many different theories speculating what truly happened to Marilyn Monroe the night before she was found dead in her home. Who was the last person to see her? Who was the last person to speak with her?  We may never know the complete truth. There is one thing that is for certain, she was most definitely an addict and ultimately her addiction likely played a role in her death, whether it was accidental or not.
