Review the autopsy report, death certificate, and FBI Vault Files of Marilyn Monroe, who was a talented American actress and iconic sex symbol of the big screen. She starred in hit movies such as Bus Stop, getting a Golden Globe nomination; and winning a Golden Globe Award for Some Like It Hot. Marilyn was married to baseball legend Joe DiMaggio before divorcing him. After her death, Joe had a half-a-dozen red roses delivered to her grave three times a week for 20 years. On August 5, 1962, Marilyn was found early in the morning dead in her bed. Her  psychiatrist, Dr. Ralph Greenson called 911 to report Monroe was found dead at her home. Her toxicology report stated that eight milligram per cent of Chloral hydrate and 4.5 milligram percent of Nembutal were found in her system. Dr. Thomas Noguchi of the Los Angeles County Coroners office recorded cause of death as "acute barbiturate poisoning," resulting from a "probable suicide." There are several conspiracy theories that Marilyn's death was the result of the mafia or CIA; or it was rumored that she had affairs with John and Robert Kennedy. It was supposedly reported that last person who talked to Marilyn was the 35th President of the United States, John F. Kennedy.
