Law enforcement sources tell us Dr. Murray confessed to LAPD cops two days after the singer's death ... he administered the powerful anesthesia Propofol to Jackson hours before his death.

We've been reporting for two weeks LAPD detectives believe Dr. Murray administered the fatal dose of Propofol. Our sources say Dr. Murray gave Jackson an IV drip of the drug, which means it seeped into his system over a period of time.

Authorities believe Dr. Murray may have fallen asleep during the IV drip and when he awoke the singer may have already been dead from an overdose of the drug. We're told paramedics found an IV stand with an empty IV bag in the room.

As we have already reported, when cops went back to Jackson's house the Monday after his death, they found a stash of drugs hidden in a closet in the room where Dr. Murray was staying -- including the drug Propofol.

Authorities believe Propofol is the cause of Jackson's death.

A DEA agent just spoke to the media outside of Dr. Conrad Murray's office in Las Vegas -- saying Murray was at home the whole time his house was being searched today by a pile of law enforcement agents.

The Assistant Special Agent in Charge said law enforcement officials were now moving on from Murray's home to search his office. The ASAC said the warrants executed this morning were for documents -- meaning anything from papers to computer hard drives.
