Marilyn Monroe was only thirty-six years old at the time of her death. On August 5, 1962, she was discovered dead in her bedroom by her live-in housekeeper, Mrs. Eunice Murray. Although the official cause of death is listed as an overdose of barbiturates, Dr. Thomas Noguchi (who performed the autopsy) could not find any trace of the drugs in her stomach or intestines, leading some to theorize that they may have been administered to the actress by intravenous injection, perhaps by someone wishing to make her death appear to be a suicide. Many theories have sprung up surrounding the circumstances of her death. Conspiracy theorists have suggested, alternately, that she was murdered by the Kennedys, the Mob, the Communists, or even by her own psychiatrist, Dr. Ralph Greenson. However, a formal investigation by the Los Angeles County District Attorney in 1982 (twenty years after her death) produced no credible evidence of foul play. Marilyn was interred in a crypt at Westwood Village Memorial Park Cemetery. For twenty years, baseball great Joe DiMaggio, one of her former husbands, had a dozen red roses delivered to her grave three times a week. She was also married briefly to playwright Arthur Miller. Other men with whom she was rumored to have had affairs include John F. Kennedy, Frank Sinatra, Howard Hughes, Marlon Brando, Dean Martin, and Orson Welles.
