Los Angeles - Police raided the home of Michael Jackson's personal doctor Tuesday, tightening their focus on the physician who reportedly gave the late superstar sedatives that may have killed him.
The raid of the Las Vegas home of Dr Conrad Murray came a day after sources in the investigation told US news media that investigators believe Murray gave Jackson a dose of the hospital anesthetic propofol hours before Jackson died of cardiac arrest.
Celebrity website TMZ.com, which is known for its excellent police sources in Los Angeles, reported that Murray told investigators he gave Jackson propofol, and that authorities believe he simply wasn't paying attention when Jackson's heart stopped.
Last week authorities raided Murray's medical offices in Houston, using a search warrant that authorized them to collect evidence of manslaughter.
The results of two autopsies have not yet been released pending toxicology reports, but investigators reportedly believe that Jackson used propofol administered intravenously as a daily sleep aid. Murray was the doctor hired to be at Jackson's side through his 50 concert comeback engagement in London and was with Jackson when he died on June 25.
Murray's lawyer has previously denied that he gave Jackson any drugs that could have led to his death.
