Cops close in on Michael Jackson doc

Police investigating Michael Jackson's death are closing in on Dr Conrad Murray, the man they believe is responsible.

Police and DEA agents searched Murray's Las Vegas home and office mere days after law enforcement scoured his Houston medical center. Authorities are seeking any and all medical records pertaining to Jackson, especially details on drugs Murray prescribed to the singer.

Complicating the investigation is the fact that Jackson used literally dozens of aliases for his prescriptions, including "Josephine Baker" and the name of his oldest son Prince.

Here is what law enforcement sources are saying about Murray so far: He admitted to giving Jackson the drug believed to have killed him, Propofol, as an IV drip. The drug is very dangerous and should never be administered outside of a hospital without heart and blood gas monitors -- neither of which were found in Jackson's home, let alone anywhere near his body. They think Murray was not monitoring Jackson properly, and the singer died in his sleep.

That's right, in his sleep. Inside sources say they believe Jackson died much earlier than his official hospital time of death -- hours earlier. Their working theory is that Murray himself fell asleep while he was supposed to be monitoring Jackson, and when he awoke, Jackson was already dead.

Bolstering this theory is the fact that Murray called his Houston office around 9 a.m., after which two of his receptionists were seen removing boxes of documents from a company storage facility. That was three hours before EMTs were called to Jackson's home -- and the boxes, as yet unfound, are suspected of containing incriminating records.

The sources also say Murray waited at least two hours, if not more, to call 911 to give himself time to clear out his offices, stash the drugs and come up with a story. They also believe Murray gave Jackson CPR on the bed, instead of a hard surface such as the floor (as is standard), because he knew it wouldn't make any difference -- Jackson was already long gone. They even believe Murray called young Prince into the room so there would be a witness to his "resuscitation" efforts.

So why didn't EMTs call Jackson's death at the scene? Murray's authority as a medical doctor overrode theirs. Again, according to sources in law enforcement, Murray demanded Jackson be transported to the ER so his death would not be called under Murray's name. In fact, video captured by tourists driving by Jackson's house shows the ambulance driving without lights and sirens -- a clear clue that Jackson was already dead. If he was still alive, according to experts, there would have been a much bigger rush to get him to an ER.

Cops also found drugs hidden in the closet of Murray's guest room in Jackson's home.

Looks like Dr Murray could soon face manslaughter charges, at the least.
