Michael Jackson had lethal levels of Propofol in his system when he died, this according to a search warrant affidavit that was unsealed in Houston today and obtained by the L.A. Times.

According to the report, Dr. Conrad Murray told cops he had been treating Jackson for 6 weeks for insomnia -- giving him 50 milligrams of Propofol every night through an IV.

Murray told cops he feared Jackson was getting addicted so he reduced the dosage to 25 mg.

The morning Jackson died, Dr. Murray gave Jackson valium at 1:30 AM, according to the report. Murray said the valium didn't work so he gave the singer an IV injection of lorazepam -- an anti-anxiety drug. Murray told cops Jackson was still awake, so he then gave him midazolam -- a sedative.

According to the report, Murray gave Jackson more drugs. He says at 10:40 AM, he administered 25 mg of Propofol. Dr. Murray told cops Jackson repeatedly demanded the drug.

As we first reported, cops found 8 bottles of Propofol in Jackson's house after he died, but they do not know where it was purchased.

According to the report, cops also found Valium, Tamsulosin, Lorazepam, Temazepam, Clonazepam, Trazodone and Tizanidine, along with the Propofol.

According to the report, the various drugs were prescribed by Dr. Murray, Dr. Arnold Klein and Dr. Allan Metzger.

Dr. Murray reportedly told cops after administering Propofol he left the room to call his Houston medical office and family members. When he returned, he says, Jackson wasn't breathing.

Dr. Murray told cops other docs had administered Propofol to Jackson, including Las Vegas Dr. David Adams. Dr. Murray said he was at a cosmetologist's office where Dr. Adams gave Jackson Propofol.

Interestingly, according to the warrant, Dr. Murray refused to sign the death certificate at the UCLA Medical Center.
