Jackson stil had pulse when found not breathing

The lawyer of Jackson's personal physician, Dr. Conrad Murray, said that he never prescribed or gave Jackson the prescription painkillers Demerol or OxyContin. A shot of Demerol given to Jackson only hours prior to his death is believed to have contributed to his demise.

Dr. Murray's lawyer, Edward Chernoff, said that the doctor was at the pop icon's rented mansion on Thursday afternoon when he discovered Jackson in bed and not breathing. The doctor immediately began administering CPR.

"He just happened to find him in his bed, and he wasn't breathing," the lawyer said. "Mr. Jackson was still warm and had a pulse," said Chernoff.

"Dr. Murray has never prescribed nor administered Demerol to Michael Jackson," Chernoff said. "Not ever. Not that day. ... Not Oxycontin (either) for that matter."

Paramedics were called to the mansion while the doctor was performing CPR, according to a recording of the 911 call. Medics spent three-quarters of an hour trying to revive Jackson. He was pronounced dead later at UCLA Medical Center.

People close to Jackson have said since his death that they were concerned about his use of painkillers. Los Angeles County medical examiners completed their autopsy Friday and said Jackson had taken unspecified prescription medication.

Murray was interviewed by investigators for three hours Saturday. His spokeswoman called Murray "a witness to this tragedy," not a suspect in the death, and police described the doctor as cooperative.
