Despite the Los Angeles Police Department’s attempt to keep Michael Jackson’s autopsy results under wraps, an Associated Press source has confirmed the rumors: the singer’s death was a homicide.

According to a search warrant affidavit unsealed today, the King of Pop’s death was a result of lethal levels of the drug propofol (a.k.a. Diprivan). In the 32-page document, Dr. Conrad Murray revealed that he had been administering 50 mg of the drug nightly to help Jackson sleep. This routine went on for approximately six weeks. Fearing Michael would become addicted, other drugs were later introduced by Murray just days prior to June 25th.

On the morning of his death, Jackson was given another 25 mg of propofol “after repeated demands/requests.”

The L.A. County coroner’s Office has had no comment on these recent developments. Homicide is just one of five classifications the coroner’s office can use to label a death. (The others being “natural,” “suicide,” “accidental” and “undetermined.”)

It is not known if and when any manslaughter charges will be filed against Murray.
