The Los Angeles County coroner has ruled Michael Jackson’s death a homicide, an unidentified law enforcement official told The Associated Press Monday.

The finding makes it more likely that criminal charges will be filed against cardiologist Conrad Murray, who was with King of Pop when he died in his rented Los Angeles mansion on June 25.

The official says the coroner determined a fatal combination of drugs was given to Jackson hours before his death. In a search warrant affidavit unsealed today in Houston, TX, a report from the L.A. County coroner’s officials indicated that official found a lethal dose of the powerful anesthetic propofol along with two sedatives in Jackson’s system.
