Police question Michael Jackson's doctor

MOSCOW, June 28 (RIA Novosti) - Los Angeles police have held an "extensive interview" with the cardiologist who tried to resuscitate Michael Jackson before his death, amid uncertainty over the causes of the pop legend's cardiac arrest.

Dr Conrad Murray reportedly disappeared several hours after Jackson's death at the age of 50 on Thursday, and failed to sign a death certificate.

"Dr. Conrad Murray, the physician who was with Michael Jackson at the time of his collapse, voluntarily contacted the Los Angeles Police Department," a police statement released on Saturday night said.

Detectives "met with Dr. Murray and conducted an extensive interview. Dr. Murray was cooperative and provided information which will aid the investigation."

The death of the 'King of Pop' has dominated the global media over the past three days, and social networking and video sites have been flooded with tributes. While grieving fans have been celebrating Jackson's musical legacy, several questions have arisen over the circumstances of his death.

The Rev Jesse Jackson, a long-serving politician who has been maintaining close contact with Michael Jackson's family, told reporters that the doctor had failed to speak to relatives after the death, and that many questions remained unanswered.

"When did the doctor come? What did he do? Did he inject him? If so, with what? Was he on the scene twice? Did he use the Demerol? It's a very powerful drug. Was he injected once? Was he injected twice?"

However, a lawyer for Murray insisted that his client was not being treated as a suspect in Jackson's death.

"It's a human tragedy and he's upset obviously over the loss of Mr. Jackson. But he is not a suspect in the death of Mr. Jackson," Matthew Alford said
