MICHAEL JACKSON's death has been officially ruled as a homicide, according to police.
Law enforcement officials have said the Los Angeles County Coroner has said the singer's death was a homicide, meaning criminal charges against Jackson's doctor are likely.
Forensic tests found the powerful anesthetic propofol acted together with at least two sedatives to cause Jackson's death June 25 in his rented Los Angeles mansion, according to the official, who spoke on condition of anonymity because the findings have not been publicly released.
Dr. Conrad Murray, a Las Vegas cardiologist who became Jackson's personal physician weeks before his death, is the target of a manslaughter investigation by the Los Angeles Police Department. A designation of homicide means that Jackson died at the hands of another, but does not necessarily mean a crime was committed.
A search warrant affidavit unsealed Monday in Houston includes a detailed account of what Dr Murray told investigators.
According to the document, Murray said he'd been treating Jackson for insomnia for about six weeks with 50 milligrams of propofol every night via an intravenous drip. But he said he feared Jackson was forming an addiction to the anesthetic, which is normally used in hospitals only, and was attempting to wean his patient by lowering the dose to 25 milligrams and adding the sedatives lorazepam and midazolam.
That combination succeeded in helping Jackson sleep two days prior to his death, so the next day, Murray told detectives he cut off the propofol - and Jackson fell asleep with just the two sedatives.
Then around 1:30 a.m. on June 25 - the day the singer died - Murray said he tried a series of drugs instead of propofol to make Jackson sleep, but they didn't work.
Murray told detectives that around 10:40 a.m. he gave in to Jackson's "repeated demands/requests" for propofol, which the singer referred to as his "milk." He administered 25 milligrams of the white-colored liquid, - a relatively small dose - and finally, Jackson fell asleep.
Murray remained with the sedated Jackson for about 10 minutes, then left for the bathroom. No more than two minutes later, he returned - and found Jackson had stopped breathing.
When he died, Jackson was skinny but not overly emaciated, and his body had bed sores, the police official claims. The singer is believed to have developed bed sores in the months following his 2005 acquittal of child molestation charges, when he went into seclusion and spent long stretches in bed.
Murray has spoken to police and last week released a video saying he "told the truth and I have faith the truth will prevail."
Jackson's family released a statement Monday, saying it has "full confidence" in the legal process and the efforts of investigators. It concludes: "The family looks forward to the day that justice can be served."
Murray didn't tell paramedics or doctors at UCLA hospital where Jackson was rushed June 25 about any drugs he administered other than lorazepam and flumazenil, according to the affidavit. The document says it was only during a subsequent interview with Los Angeles Police detectives that Murray gave a more full accounting of the events leading up to the 911 call.
The coroner's office has not publicly released its autopsy findings, citing a request from police detectives to withhold results until their investigation is complete.
