Police search Jackson doctor's home for the second time in a week

Investigators probing Michael Jackson's sudden death raided the home and office of his doctor for the second time in a week, looking for evidence on whether he committed manslaughter by administering a powerful drug to the pop icon that possibly caused his heart to stop.

Police and Drug Enforcement Administration (DEA) agents, carrying search warrants were "looking for a lot of things" when they raided doctor Conrad Murray's Las Vegas premises yesterday, a DEA spokesman said.

Last week, federal drug agents and Los Angeles police searched Murray's Houston clinic and a storage locker and came out with items including 27 tablets of weight loss drug phentermine, a tablet of the muscle relaxant clonazepam, and computer hard drives among other things.

The latest raid came a day after a report revealed that Murray had given Jackson anesthetic propofol -- commonly known as Diprivan -- in the 24 hours before his death, leading to speculation that investigators might be looking for the sedative at the physician's home and office.

Mike Flanagan, Assistant Special Agent in Charge, DEA, said the investigators were looking for documents and computer records but declined to disclose further details, CNN said.

Murray, a Texas-based cardiologist, was at Jackson's rented home in Holmby Hills when the pop star died on June 25.

His lawyer, Edward Chernoff, insists that his client did not prescribe or administer anything that could have killed the pop star.
