The cardiologist who reportedly was in Michael Jackson's Los Angeles mansion when the entertainer collapsed practices medicine in at least three states and is the graduate of a medical school in Nashville.
A woman who answered the phone Friday at Dr. Conrad R. Murray's clinic in Houston confirmed to The Associated Press that Murray was Jackson's cardiologist.
The Los Angeles Times reported that Murray was performing CPR on Jackson when paramedics arrived at his home Thursday, and Murray's car was later towed by police from the home.
Los Angeles police want to interview Murray but stress he is not under criminal investigation.
Murray graduated from Meharry Medical College in 1989. Government records show he holds licenses to practice in California, Nevada and Texas. He was licensed in 2001 in Hawaii, but it wasn't immediately clear if that license is current.
State regulators had no records of any disciplinary actions against him.
Murray's office in Las Vegas, Global Cardiovascular Associates Inc., was locked and dark Friday. Reporters gathered in the hallway outside. He did not immediately return messages left on his office voicemail.
Mary Russell, property manager for the sleek, three-story office building across from Desert Springs Hospital, said she had not seen Murray all week.
A reporter who tried to visit Murray's Las Vegas home was turned away by two armed guards at the entrance to the gated community where it's located.
Records show he has had financial trouble. Murray filed for bankruptcy in California in 1992, when he was listed as living in Loma Linda, where he had done graduate work at Loma Linda University. He had several tax liens filed against him in California and Arizona between 1993 and 2003.
