Prince Autopsy Results May Take Weeks, Authorities Say

MINNEAPOLIS (AP) - The Latest on the death of superstar musician Prince (all times local):

3:30 p.m.

The local sheriff says the last time Prince was seen alive was the night before emergency crews found him unresponsive at his home in suburban Minneapolis.

Carver County Sheriff Jim Olson says an acquaintance dropped Prince off at his compound around 8 p.m. Wednesday. Olson says his Prince found unresponsive late Thursday morning in an elevator on this first floor of his home, after staff members were unable to get ahold of the 57-year-old musician.

Olson says Prince was "a very private person" and he didn't think it was unusual for the singer to be alone at his sprawling compound. The sheriff declined to say who made the initial 911 call, saying that information is private.

But he promised to fully investigate the death, saying: "This is certainly a big event internationally and nationally and I can tell you that we are going to leave no stone unturned on this and make sure the public knows what happened."

Minnesota authorities are declining to discuss whether any prescription drugs were found in Prince's home after his death, or to discuss a report that the musician suffered a drug overdose less than a week before he died.

Carver County Sheriff Jim Olson and a medical examiner's office spokeswoman refused to comment Friday when asked about prescription drugs or a possible overdose. Celebrity website TMZ.com, citing "multiple" unnamed sources, has reported that Prince received treatment for a painkiller overdose while traveling home from concerts in Atlanta last week.

TMZ reported last week that Prince's flight made an emergency landing early April 15 in Moline, Illinois, where he was briefly hospitalized.

Representatives for Prince have not responded to requests from The Associated Press for comment on the reports.

Authorities say there were no signs of trauma on Prince's body when he was found unresponsive at his home, and that suicide isn't suspected in the musician's death.

Carver County Sheriff Jim Olson released the information during a news conference Friday.

The sheriff says the investigation is ongoing into the death of the 57-year-old musician, who was found dead Thursday morning at his home in suburban Minneapolis.

An autopsy was completed earlier Friday, though preliminary findings weren't immediately released

Prince's former drummer and protégé Sheila E. says the singer was bothered by the same physical issues that many musicians suffer.

Sheila E. talked to The Associated Press on Friday, a day after the 57-year-old musician was found dead at his suburban Minneapolis home.

She says she knew Prince had issues with his hip and knee from his years jumping off risers and speakers on stage in heels. She says he kept doing it because he loved it.

Still, she says Prince "really took care of himself," including eating well. She says she tried to copy what he did to stay fit.

An autopsy was completed Friday, but the medical examiner's office said results wouldn't be announced for days or weeks.

Authorities say it could take days or even weeks before the public learns the cause of Prince's death.

An autopsy is scheduled for Friday morning, a day after the 57-year-old music superstar was found dead at his studio compound in suburban Minneapolis.

A spokeswoman for the Midwest Medical Examiner's Office says the agency doesn't plan to release any preliminary information until autopsy results are completed.

Spokeswoman Martha Weaver says she expects the process will take days or even weeks for tests to be completed. She also says no preliminary results will be released by her office, and that the office will wait to release findings when all the information is in.

Once the physical autopsy is finished, Prince's body will be released to a designee of his family.

Authorities responded to a medical call at Prince's Paisley Park on Thursday morning to find him unresponsive in an elevator. The local sheriff says first-responders performed CPR, but that Prince couldn't be revived.
