Authorities Raid Home, Second Office of Michael Jackson's Doctor

Suspicion surrounding the involvement of Michael Jackson's doctor, Dr. Conrad Murray, in the pop star's death intensified this morning, as several DEA agents and Los Angeles police detectives arrived at Murray's Las Vegas medical office and home armed with a search warrant.

Federal and local investigators are searching the Las Vegas home and office of Dr. Conrad Murray, Michael Jackson's physician, who authorities believe may have injected the singer with a lethal dose of anesthesia the day he died, law enforcement sources told ABC News.

Uniformed Metro Las Vegas officers accompanied the federal drug agents and LAPD investigators as they entered Global Cardiovascular Associates on Flamingo Road in Las Vegas.

A locksmith has arrived at Murray's house, an ABC News producer on the scene reports.

The scenes are similar to a raid on Murray's other medical office in Houston, TX last week. A storage shed there used by Murray was also searched.

Officials said the search warrant obtained for last week's raid was based on the preliminary results of Jackson's autopsy, which showed the cause of death to be connected to the anesthetic drug Propofol. Murray reportedly administered Propofol to Jackson on the day he died. The warrant stated that authorities were looking for "implements and instruments used in the commission of a crime and for property or items constituting evidence of the offense of manslaughter that tend to show that Dr. Conrad Murray committed the said criminal offense."

Today's search is another sign that Murray continues to be the focus of the investigation into Jackson's sudden death. He has been interviewed twice by investigators but has not responded to questions of possibly administering Propofol, a drug normally only used in hospital operating rooms, to Jackson.

In a statement issued before last week's raid, Murray's attorney Ed Chernoff said Murray was cooperating with the investigation.

"The coroner wants to clear up the cause of death, we share that goal," Chernoff said. He has said that Murray "should not be a target of criminal charges."

Murray is the cardiologist and "personal physician" who was by Jackson's side on the day of his death. Murray's attorney Edward Chernoff previously told Good Morning America that it took Murray a while to find anyone in Jackson's rented mansion to help him call 911 after he failed to revive the superstar.

"We can't tell you exactly when 911 was called," attorney Edward Chernoff told "Good Morning America" last week.
