A potent and lethal dose of propofol was the likely factor that induced the death of pop king Michael Jackson, his personal doctor Conrad Murray told the authorities, the Los Angeles Times reported Monday.
In a search warrant affidavit declassified in Houston, Murray told the Los Angeles Police Department (LAPD) that he had kept giving Jackson 50 milligrams of propofol every night for about six weeks in an effort to treat his insomnia.
U.S. pop star Michael Jackson performs "We are the World" during the World Music Awards at Earl's Court in London November 15, 2006.
The Los Angeles County coroner's office did find large amount of the anesthetics in Jackson's body after his June 25 death, but the conclusion was withheld because the investigation was ongoing.
Fearing an addiction was taking root in Jackson, Murray began to wean him off the drug by reducing the daily dosage by half and mixing it with two other sedatives, lorazepam and midazolam. From June 23 on, he administered only two medications excluding the propofol.
Two days later, Murray tried to help Jackson go into sleep, also without using propofol. From 2 a.m. (0900GMT), he injected lorazepam intravenously twice. He then gave the pop star midazolamsince Jackson was still awake, the report said.
He used various drugs before 10:40 a.m. (1740GMT) when he injected 25 milligrams of propofol after Jackson insisted in getting the drug.
