WASHINGTON - Marijuana and several empty bottles of drugs were found at Michael Jackson’s house when it was searched following his death, unsealed search warrants have revealed.

Two bags of marijuana, a bottle of temazepam (used to treat sleeplessness), empty bottles of the sedatives lorzaepam and diazepam, and four empty pill bottles were found in the search, reports People magazine.

According to the warrants, investigators believe Jackson had “received injection of an unknown medication, prior to his death.” Other documents revealed that MJ’s physician, Conrad Murray, had been administering him doses of anesthetic propofol intravenously.

The search warrants were served on June 29, four days after the King of Pop died. The documents also say Dr Murray left the hospital “against the objections of the investigating officers” and that he could not be reached for days after that.

The warrant also discloses that, on the day of Jackson’s death, as investigators were at the house, “family members of the decedent notified Los Angeles County Coroner’s Assistant Chief Ed Winter that they had located a quantity of tar heroin in [Jackson's] bedroom on the second floor of the residence. Winter notified LAPD detectives of the found evidence.” There is no mention in the warrant if the evidence really turned out to be heroin.

However, Winter refused to give any information on the evidence or Jackson’s autopsy report. (ANI)
