A search warrant affidavit has showed that Michael Jackson had lethal levels of Propofol in his system when he died, the Associated Press reported.
According to the report, Dr. Conrad Murray told investigators he was giving Jackson 50 milligrams of Propofol intravenously every night for insomnia. Murray then later reduced the dosage to 25 milligrams over fears that Jackson could become addicted.
The morning Jackson died, Dr. Murray gave Jackson valium at 1:30 AM, according to the report. Murray said the valium had no effect and he injected the singer with lorazepam -- an anti-anxiety drug. Murray told investigators that Jackson was still awake so he gave him midazolam -- a sedative, TMZ reported.
