Coroner: No Foul Play In Jackson Death

LOS ANGELES - Los Angeles County coroner's spokesman Craig Harvey says determining the cause of Michael Jackson's death will require further neuropathology and pulmonary tests that will take four to six weeks. A source tells the AP that Jackson died of an apparent heart attack.

Harvey says there were no signs of foul play or trauma to the body during the three-hour autopsy. He also says Jackson was taking some unspecified prescription medications.

The spokesman says Assistant Chief Coroner Ed Winter is with Jackson's family.

Harvey says the police department has requested a security hold on the investigation which limits how much the coroner's office can say about the case. He says the death became a coroner's case because there was no doctor to sign the death certificate.

Harvey says the body will be released once the family selects a mortuary.

Michael Jackson apparently suffered a heart attack, a person with knowledge of the situation told The Associated Press on Friday. Police planned to interview the doctor who was with the pop icon during his last minutes and pumped his chest in a vain attempt to save his life.

The person, who was not authorized to speak publicly and requested anonymity, said Jackson had suffered a heart attack. Jackson's brother Jermaine had said the pop singer apparently went into cardiac arrest -- which often but not always happens because of a heart attack.

Authorities said they would speak with the doctor, identified by the Los Angeles Times as cardiologist Conrad Murray, and said they had towed his car from Jackson's rented mansion because it could contain medication or other evidence. Police stressed that the doctor was not a criminal suspect.

Deputy Police Chief Charlie Beck said he hoped the doctor would shed light on the coroner's findings and "lead us to some conclusions."
