Court documents have revealed that Michael Jackson died from lethal levels of the anesthetic propofol.
According to the L.A. Times, a search warrant affidavit confirms that Jackson was taking the powerful drug in the weeks before his death. The search warrant states that Conrad Murray told the LAPD that he had been treating Michael's insomnia with 50 mg of propofol every night.
The court documents also state that Dr. Murray told investigators he feared Jackson was forming an addiction to the drug -- so he stopped administering propofol to him.
Murray admitted to investigators that on the morning of Jackson's death, he gave the pop icon 25 mg of the drug after Michael repeatedly asked for it. The doc confirmed to authorities that after administering the drug, he then stepped away to make phone calls. When he returned, Michael wasn't breathing, and he dialed 911.
There is no word yet on whether Murray's decision to give Jackson propofol outside of a hospital will prompt authorities to charge him with involuntary manslaughter.
