Michael Jacksons Death - Police search the home of MJ's doctor Conrad Murray.

Police search the home of Michael Jackson's doctor Conrad Murray. It has emerged that the singer died after he was given a powerful, surgical anesthetic through a drip-feed to help him sleep. Officials with the US Drug Enforcement Administration were at Dr Murray's Las Vegas home on Tuesday as part of a manslaughter investigation into the singer's death. Dr Murray, a cardiologist with practices in Las Vegas and Houston, had his Texas office and a storage unit searched last week by DEA agents. Court records show the agents were searching for evidence suggesting that the doctor committed manslaughter.

Police stated that Dr Murray is cooperating and have not labeled him a suspect. Investigations into the King of Pop’s death have revealed that he relied on a strict drugs regime. A doctor would reportedly administer the anesthetic, a strong sedative usually given to patients before surgery, when Jackson went to sleep and turn off the drip at the time Jackson said he wanted to wake up.

On June 25, the day Jackson died, Dr Murray gave him the drug some time after midnight, said an official. Although the authorities are understood to believe that propofol was the ultimate killer, Jackson's body is said to have contained a lethal cocktail of prescription drugs, including OxyContin and Demerol. Edward Chernoff, Dr. Murray's lawyer, has said the doctor never prescribed or administered any drug that "should have killed" the megastar. He has never said whether the doctor gave Jackson propofol, the brand name of which is Diprivan. Bottles of the drug were discovered at Jackson's home and investigators believe he had been using it for approximately two years.

When asked about the latest claims, Mr. Chernoff stated "Things tend to shake out when all the facts are made known, and I'm sure that will happen here as well". Mr Chernoff has already admitted that Dr Murray did not call an ambulance for 30 minutes after he found Jackson unresponsive and instead tried to resuscitate him. "This doctor is in serious trouble," Roy Black, a criminal defense lawyer, told Good Morning America this morning. Mr Black said that, if charged, Dr Murray – who was to have accompanied the singer during his London concerts – would have to prove there was a "sound medical reason" to give Jackson a drug intended for use in the operating room.

Toxicology reports are expected later this week but investigators are working under the theory that propofol caused the singer's heart to stop, an official said. This powerful drug should never have been have been administered in a private home. This sad saga is far from over and our hearts go out to Michael and the loved ones he leaves behind.
