Marilyn Monroe Murdered by CIA to Protect Kennedy Brothers

Record	OBS-0521
Category	History/Assassinations
Status	DEBUNKED
Summary	Conspiracy theorists claim Marilyn Monroe was murdered by the CIA to prevent her from revealing affairs with John F. Kennedy and Robert F. Kennedy, as well as knowledge of a CIA plot to kill Fidel Castro. They point to a missing red diary, inconsistencies in the autopsy, and alleged pressure on the coroner as evidence. The official ruling was probable suicide from a barbiturate overdose.
Origin	Theories emerged in the mid-1960s, shortly after Monroe's death on August 4, 1962, and gained traction with books and investigations in the 1970s and 1980s.
Claimed	Monroe was murdered by CIA operatives to protect the Kennedy brothers from scandal. Monroe had a red diary containing details of her affairs with the Kennedys and the CIA plot against Castro, which disappeared from the coroner's office. The coroner's report was falsified; no pills were found in her stomach, suggesting injection, and the deputy coroner signed under duress. Monroe's death was not suicide; she was not suicidal at the time.
Evidence / consensus	The official investigation and subsequent reviews have concluded that Monroe's death was a probable suicide from a barbiturate overdose. No credible evidence supports the murder theory, and the missing diary and other anomalies are explained by procedural lapses and the passage of time.

> OBSERVER NOTE:
A classic celebrity-death conspiracy with no substantiating evidence. The missing diary and autopsy quirks fuel speculation, but the official record stands.
