Michael Jackson's Death Ruled a Homicide

It's official: The Los Angeles County coroner announced on Friday that Michael Jackson's death has been ruled a homicide.

According to the coroner's report, the singer suffered from "acute propofol intoxication." Other drugs detected in his system included lorazepam (Ativan), midazolam, diazepam (Valium), lidocaine (an anesthetic), and ephedrine.

The homicide finding – meaning death at the hands of another – is only one of five rulings a coroner can make in a death investigation. Among the others: natural, suicide, accident, and "could not be determined."

According to unsealed search warrants, Jackson's personal physician, Dr. Conrad Murray, told LAPD detectives that he had been treating the singer for insomnia for about six weeks, and had been giving Jackson 50 milligrams of propofol every night intravenously. Jackson referred to propofol, a cloudy white fluid, as his "milk," according to the affidavit.

But Murray told police he was worried Jackson was becoming addicted to the powerful anesthetic and tried to ease him off it. But on the morning of Jackson's death on June 25, Murray told authorities that after repeated demands from the singer to give him propofol, the doctor gave in and administered 25 milligrams of propofol diluted with lidocaine to keep him sedated.

Minutes after giving him the drug, Murray found Jackson not breathing. The singer, 50, was pronounced dead at UCLA Medical Center.

LAPD had no comment on Friday regarding the coroner's ruling. Murray's attorneys have denied any wrongdoing on behalf of the doctor.
