Title: Death of Marilyn Monroe
Content:  According to him, her doctors Greenson (psychiatrist) and Engelberg (personal physician) had been trying to stop her abuse of Nembutal. In order to monitor her drug use, they had agreed to never prescribe her anything without first consulting with each other. Monroe was able to persuade Engelberg to break his promise by lying to him that Greenson had agreed to it. She took several Nembutals on August 4, but did not tell this to Greenson, who prescribed her a chloral hydrate enema; the combination of these two drugs killed her. Afraid of the consequences, the doctors and Eunice Murray then staged the death as a

Content:  At 4:25a.m., the LAPD was notified. Monroe died between 8:30 p.m. and 10:30p.m. on August 4, and the toxicology report showed that the cause of death was acute barbiturate poisoning. She had 8 mg% (milligrams per 100 milliliters of solution) chloral hydrate and 4.5 mg% of pentobarbital (Nembutal) in her blood, and 13 mg% of pentobarbital in her liver.

Noguchi explained that hemorrhaging of the stomach lining indicated that the medication had been administered orally, and that because Monroe had been an addict for several years, the pills would have been absorbed more rapidly than in the case of non-addicts. He also denied that Nembutal leaves dye residue. He noted that only very recent needle marks are visible on a body, and that the only bruise he noted on Monroe's body, on her lower back, was superficial and its placement indicated that it was accidental, and not linked to foul play. Noguchi finally concluded that based on his observations, the most probable conclusion is that Monroe committed suicide.

In the 1970s, claims surfaced that Monroe's death was a murder and not suicide. Due to these claims, Los Angeles County District Attorney John Van de Kamp assigned his colleague Ronald H.

Kennedy ended their affair, she threatened to reveal their association. Kennedy and Peter Lawford attempted to prevent this by enabling her addictions. According to Summers, Monroe became hysterical and accidentally overdosed, dying in an ambulance on the way to the hospital. Kennedy wanted to leave Los Angeles before Monroe's death became public to avoid being associated with it, and therefore her body was returned to Helena Drive and the overdose staged as a

There were no signs of external wounds or bruises on the body. The findings of the inquest were published on August 17; Chief Coroner Theodore Curphey classified Monroe's death a "probable suicide".

The Los Angeles County coroner's office was assisted in the inquest by psychiatrists Norman Farberow, Robert Litman, and Norman Tabachnik from the Los Angeles Suicide Prevention Center, who interviewed Monroe's doctors and psychiatrists on her mental state.

At approximately 3 a.m. on Sunday, August 5, she noticed that Monroe had locked herself in her bedroom and appeared unresponsive when she looked into the bedroom through a window. Murray alerted Greenson, who arrived soon after, entered the room by breaking a window, and found Monroe dead. Her death was officially ruled a probable suicide by the Los Angeles County coroner's office, based on precedents of her overdosing and being prone to mood swings and suicidal ideation. No evidence of foul play was found, and accidental overdose was ruled out because of the large amount of barbiturates she had ingested.
