LOS ANGELES (AP) - A 911 caller from Michael Jackson's home can be heard saying he wasn't breathing or responding to efforts to revive him.
The Los Angeles Fire Department released Thursday's 911 call.
The caller reported that Jackson was on a bed, he wasn't breathing and wasn't responding to CPR.
The unidentified caller said Jackson only was with his personal doctor at the time.
Jackson was pronounced dead later Thursday at UCLA Medical Center.
Los Angeles County coroner's Lt. Brian Elias says an autopsy began shortly after 9 a.m. Friday and could take three to four hours.
Additional laboratory tests, including toxicology tests, are likely and those results wouldn't be known for several weeks.
The call's release came as a newspaper reports the doctor whose car was towed from Michael Jackson's house is a cardiologist who practices in California, Nevada and Texas.
A woman who answered the phone Friday at Dr. Conrad C. 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 was performing CPR on Jackson when paramedics arrived at the entertainer's home Thursday.
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.
Los Angeles police say they want to speak to the doctor but stressed he was not under criminal investigation.
A Los Angeles police spokeswoman says: "We have not been able to interview the doctor yet. His car was impounded because it may contain medications or other evidence that may assist the coroner in determining the cause of death."
Meantime Jackson's death has led to skyrocketing sales of his music and videos online.
After the pop icon's death was announced Thursday, Amazon.com sold out within minutes all CDs by Michael Jackson and the Jackson 5. That comes Friday from vice president of music and video Bill Carr.
Carr says 60 percent of Amazon's CD orders Thursday were for Michael Jackson music, something he called "stunning."
And Barnes and Noble said that its Web site and brick-and mortar stores are currently sold out of most Jackson CDs, DVDs and books.
Both companies say they are working to get the products back in stock.
