CNS--Los Angeles police and federal agents today searched the Las Vegas home and office of Michael Jackson's physician, Dr. Conrad Murray.
The search by LAPD officers, Drug Enforcement Administration agents and Las Vegas police is part of the investigation into Jackson's June 25 death, Officer Bruce Borihanh of the Media Relations office said.
The Los Angeles County coroner's office is expected to release the results of post-mortem toxicology tests this week. They are widely expected to show that Jackson had been given propofol, an anesthetic known by the brand name Diprivan, which doctors say should not be administered outside a hospital setting.
Typically, an anesthesiologist is in charge of administering the drug and monitoring the patient.
Murray, 51, a cardiologist, is the focus of what an affidavit in support of a search warrant for his Houston office described as a manslaughter investigation.
Murray was at Jackson's rented Holmby Hills estate when the singer was found unconscious.
The Associated Press quoted a law enforcement official as saying Monday that Murray gave Jackson propofol through an IV on the day he died, and that investigators are working under the theory that the drug caused Jackson's heart to stop. The official told the AP that Jackson regularly received propofol to help him sleep.
In response, Murray's lawyer, Ed Chernoff, said Monday in a statement: "It's a waste of time responding to all these timed `leaks' from `anonymous' sources. I feel like a horse swatting flies. Everyone needs to take a breath and wait for these long delayed toxicology results ..."
TMZ.com reported reported that it was Murray himself who told Los Angeles police detectives -- two days after Jackson's death -- that he had administered the drug hours before the pop star died.
Chernoff has said that his client "didn't prescribe or administer anything that should have killed Michael Jackson."
Craig Harvey of the coroner's office said he would give the news media a one-day advance notice of when the toxicology report would be made public.
Jackson was gearing up for a run of 50 concerts in London when he died.
