Marilyn Monroe was born Norma Jeane Mortenson on June 1, 1926, in Los Angeles, California. She spent most of her childhood in foster homes and orphanages, and she began her career as a model and actress in the late 1940s. Monroe became a cultural icon and a sex symbol during the 1950s and early 1960s, starring in films such as "Gentlemen Prefer Blondes," "Some Like It Hot," and "The Seven Year Itch."

On August 5, 1962, Marilyn Monroe was found dead in her home in Brentwood, Los Angeles, at the age of 36. The official cause of death was listed as "acute barbiturate poisoning," and the death was ruled a probable suicide. However, over the years, many conspiracy theories have arisen surrounding her death.

One theory suggests that Monroe was murdered by the Kennedy family because of her alleged affairs with both President John F. Kennedy and his brother Robert F. Kennedy. Some also believe that Monroe was killed by organized crime figures because of her connections to them through her former husband, Joe DiMaggio, and her alleged affair with mobster Sam Giancana.

Despite the many conspiracy theories, no evidence has ever been found to support any of these claims, and the official ruling of Monroe's death as a probable suicide remains the most widely accepted explanation.
