Was it suicide? Was she killed? Or was it an accidental overdose, like the death certificate claimed?
Marilyn Monroe was found dead by her psychiatrist, Dr Ralph Greenson, at some point between midnight and four thirty or so on the morning of August 5, 1962. He called another doctor, Hyman Engelberg, and Monroe is certified dead. Only then are the police called.
The proximate cause of her death was poisoning – an acute barbiturate overdose, as the coroner put it. But there were a number of inconsistencies in the nature of the dose and the apparent method of its consumption. Furthermore, in the course of the investigation, witnesses made a number of contradictory statements (in some cases contradicting not just each other, but also reality), and the evidence – what little there is – is ambiguous.
It is widely believed, even today, that she was murdered, but no charges have ever been brought for that crime.
