In the ongoing investigation of Michael Jackson’s death and all things preceding, Dr. Conrad Murry is now under scrutiny.

Murray, who is reportedly in Las Vegas at the moment, served as Jackson’s personal physician and was with the star when he died; he is licensed in California, Nevada and Texas and, according to his lawyer, has been nothing but cooperative with investigators.

According to reports, several dozen Drug Enforcement Administration agents, along with local uniformed police officers, turned up at the Houston offices of the doctor to carry out a search warrant this morning.

Just yesterday, Murray’s lawyer, Ed Chernoff, released a statement reiterating that Murray was not, and should not, be a suspect, and that investigators recently requested additional medical records from the doctor.
