Jackson's doctor left room after sedation

Michael Jackson's personal doctor Conrad Murray left the room the morning the "King of Pop" died after administering the singer a powerful sedative, the Los Angeles Times reported Thursday.

Murray, 51, is identified in court records as a suspect in a Los Angeles police department manslaughter investigation, the newspaper reported, citing three people familiar with the investigation.

Jackson died in Los Angeles on June 25 at age 50 from an apparent cardiac arrest.

Murray had legally obtained a powerful drug, Propofol, from a Las Vegas pharmacy and gave it to Jackson as treatment for insomnia, the unnamed sources told the Times.

The drug is usually reserved for use in operating rooms.

Murray, who began working as Jackson's personal doctor in May, acknowledged to police two days after the singer's death that he obtained and repeatedly gave Jackson the medicine.

One law enforcement source told the newspaper that Jackson had been taking the drug as a sleep aid on and off for a decade.
