L.A. coroner now considers the death of Michael Jackson a homicide

NBC News has confirmed that the Los Angeles County Coroner now consider the death of Michael Jackson a homicide.

And their investigation continues to center on the pop star’s personal physician Dr. Conrad Murray, sources saying he could be charged with manslaughter.

Police searched Dr. Murray’s Texas clinic last month.

New information from search warrant affidavits unsealed today in Houston show Jackson had “lethal” levels of the powerful anesthetic propofol in his blood the day he died.

The warrants from that raid also provide some background.

They indicate that Dr. Murray had been treating the pop star for insomnia for about 6 weeks, giving Jackson 50-milligrams of propofol intravenously every night.

The bigger problem may have come the night before, and in the early morning hours of the day he died, when, according to the warrants Dr. Murrary was apparently worried Jackson was becoming addicted to propofol.

Dr. Murray then tried to lower his dose, while combining the drug with other powerful sedatives.

“This is not a drug to use at home, so by virtue of the fact that he’s using it all is I think dangerous and reckless.  So to then try to titrate it and figure out to make it go better, to use a little less or a little more, mixing with other drugs, it’s a recipe for disaster,“ says anesthesiologist Dr. Howard Nearman.

A disaster that investigators say ended two months ago with Jackson’s death.
