According to the affidavit, the LA chief coroner "had reviewed the preliminary toxicology results and his preliminary assessment of Jackson's cause of death was due to lethal levels of propofol".
Court records showed that Murray had been giving Jackson 50mg of propofol intravenously every night.
The Press also quotes the unnamed official, who spoke on condition of anonymity, as saying two sedatives were also found in Jackson's system.
Milk
The court document states that Jackson was "very familiar" with propofol, a cloudly white fluid, and referred to it as his "milk".
Other drugs were also found in Jackson's system according to the coroner's toxicology report, but none of them were believed to have been a factor in his death.
According to a report published by Usmagazine.com, Murray told LAPD detectives that he was growing increasingly concerned that Jackson was becoming addicted to propofol. As a result, he'd been lowering the dose he was administering to the star, and mixing the anaesthetic with two other sedatives - lorazepam and midazolam.
Court records show that on June 23 - two days before the star's death - Murray reportedly gave Jackson two medications and witheld propofol. On the day Jackson died - June 25 - Murray, according to the records, gave Jackson a number of sedatives. When neither of them took effect, he said he administered a dose of propofol.
Murray is then reported to have left the star in his bedroom to make some phone calls. When he returned to see Jackson, the star was not breathing.
that Murray waited for up to half an hour before calling paramedics after he found the King of Pop unconscious at his Los Angeles home.
A lawyer representing the cardiologist said in July that Murray had found the superstar stricken in the bedroom of his rented Beverly Hills mansion, and scrambled for up to 30 minutes to find a landline to call 911 as the pop icon lay dying, lawyer
Edward Chernoff
said.
A spokesperson from the law firm representing Murray said the delay in calling 911 stemmed from the doctor not knowing the address of the house he was in.
A statement on behalf of the family published by Usmagazine com, says:
"The Jackson family has full confidence in the legal process, and commends the ongoing efforts of the L.A. County Coroner, the L.A. District Attorney and the L.A. Police Department."
Chatter says the homicide ruling now makes it more likely that criminal charges will be brought against Murray.
"The family looks forward to the day that justice can be served," the statement added.
