The Los Angeles coroner has ruled that singer Michael Jackson's death was a homicide.
The coroner concluded the cause of Jackson's death was acute intoxication from the anaesthetic propofol and that other drugs, including the sedative Lorazepam, were in his system.
The coroner's statement said the drugs Midazolam, Diazepam, Lidocaine and Ephedrine were found.
Michael Jackson suffered cardiac arrest on 25 June at his home in Los Angeles, aged 50.
The coroner's report is the first official statement that the singer's death has been ruled homicide.
Los Angeles police say they are referring the case to prosecutors for possible criminal charges to be filed.
The police investigation into the death is continuing. The inquiry has centered on prescription drugs Jackson had in his system, and has focused on several doctors who were caring for the singer when he died, particularly his personal physician, Dr Conrad Murray.
