Coroners declared on Friday that Michael Jackson's death was a homicide and revealed the singer had a lethal cocktail of six different drugs in his body when he died.
Ending several weeks of feverish speculation that has followed Jackson's sudden death in Los Angeles on June 25, the Los Angeles County Coroner's Office issued a brief statement ruling that the superstar's death was unlawful.
The statement said that while "acute intoxication" from the powerful anesthetic propofol was the primary cause of death, Jackson, 50, had also suffered from having other drugs in his system.
As well as propofol, powerful prescription drugs including lorazepam, midazolam, diazepam, lidocaine and ephedrine were found in Jackson's body.
Jackson's personal doctor Conrad Murray is already under investigation over the star's death.
According to the warrant affidavit unsealed this week, Murray admitted to police that in an effort to help rid Jackson of chronic insomnia, he administered intravenous injections of 50 milligrams of propofol nightly during the six weeks prior to his June 25 death.
The coroner's statement said police investigators and public prosecutors had ordered that the full toxicology report concerning Jackson be withheld until further notice.
