Cause of Jackson's death still undetermined but no signs of foul play

Los Angeles County coroner’s spokesman Craig Harvey says determining the cause of Michael Jackson’s death will require further tests that will take four to six weeks.

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

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

Police investigating Jackson’s death Friday were seeking to interview one of the pop king’s doctors and seized a car that they said may contain drugs or other evidence.

As the three-hour autopsy began Friday morning, police towed a BMW from Jackson’s rented home “because it may contain medications or other evidence that may assist the coroner in determining the cause of death,” police spokeswoman Karen Rayner said.

She said the car belongs to one of Jackson’s doctors whom police wanted to interview. Rayner stressed the doctor was not under criminal investigation.

The Los Angeles Times has identified the physician as Dr. Conrad Murray, 51, a Las Vegas cardiologist, and reports that Murray was administering CPR to Jackson when paramedics arrived.

A woman who answered the phone Friday at Murray's clinic in Houston confirmed to The Associated Press that Murray was Jackson's cardiologist. The woman, who refused to give her name, would not confirm the Los Angeles Times report that Murray performed CPR on Jackson.

The Los Angeles Times cites other published reports saying Jackson had received a shot of Demerol before going into cardiac arrest.

The Texas State Board of Medical Examiners Web site shows no complaints filed against Murray in the four years he's been a licensed cardiologist in Texas.

In a 911 call released by fire officials, a caller reports Jackson was on a bed and not breathing or responding to CPR. The unidentified caller said Jackson only was with his personal doctor at the time. The pop star died later Thursday afternoon at UCLA Medical Center.

As stores reported they were inundated with orders for Jackson’s music, a chorus of grief for the megastar spread around the world, from statesmen to icons of music to legions of heartbroken fans.

“I can’t stop crying. This is too sudden and shocking,” said Diana Ross, who helped launch Jackson’s career. “I am unable to imagine this. My heart is hurting.”

Lisa Marie Presley, briefly married to the pop icon in the mid-1990s, said he had confided to her 14 years ago that he worried about facing the same tragic fate as her father, Elvis Presley, who died of a drug overdose at age 42.

“The world is in shock but somehow he knew exactly how his fate would be played out some day more than anyone else knew, and he was right,” she wrote in a long, emotional statement on her MySpace page online.

The White House also weighed in for the first time, with a spokesman saying President Barack Obama saw Jackson as a spectacular performer and music icon whose life nonetheless had sad and tragic aspects. The House of Representatives observed a moment of silence...
