Michael Jackson was killed by a lethal dose of the powerful anesthetic propofol, according to findings unsealed in court documents by the Los Angeles chief medical examiner.

The document was released by the Harris County District Clerk in Houston, where Dr. Conrad Murray's office had been raided by U.S. agents on July 22.

Dr. Conrad Murray, who was in Jackson's personal bedroom on June 25 administering drugs to ease the pop star to sleep, administered a wide range of drugs to Jackson before he died, including a 25-milligram dose of propofol via an intravenous drip at 10:40 a.m. PDT, the state search warrant said.

Jackson went to sleep after Murray administered the propofol, and Murray stayed by his side for about 10 minutes and then left to go to the restrooom and relieve himself, the search warrant said.

Murray was out of Jackson's room for about 2 minutes and when he returned, Jackson was no longer breathing, the warrant said.

Murray's attorney, Ed Chernoff, was not available to comment.

Michael Jackson suffered cardiac arrest and died on June 25 at age 50.

The Los Angeles Police Department also announced on Monday that Michael Jackson's death was homicide, according to MSNBC’s report.
