Investigators Try To Find Prince's Cause Of Death

An autopsy is scheduled Friday to determine what caused the death of the iconic musician Prince, who was found unresponsive in an elevator by sheriff's deputies at his suburban Minneapolis compound a day earlier.

Carver County Sheriff Jim Olson said deputies responded to a medical call at 9:43 a.m. Thursday. Medical personnel performed CPR, but couldn't revive the 57-year-old Prince, who was pronounced dead at 10:07 a.m.

A transcript from a 911 call shows an unidentified male phoned in the emergency, telling the dispatcher "we're at Prince's house" and "the person is dead here," but the caller struggled to figure out the exact address, CBS News correspondent Jamie Yuccas reports.

On the streets of Minneapolis Thursday night, thousands of fans celebrated Prince as he would've wanted them to - with a sing-along and an all-night dance party.

The singer's death came two weeks after he canceled concerts in Atlanta because he wasn't feeling well. He performed April 14 in Atlanta, apologizing to the crowd shortly after coming on stage.

While talking to the crowd between songs, he joked about having been "under the weather," giving a slight smile. His voice seemed a bit weak at times when he spoke, but he sounded fine when singing during the 80-minute show, which featured "Nothing Compares 2 U" and his finale, "Baby, I'm A Star."

He sat at his piano for most of the show, but stood up at times to pound the keys and walked around the piano a couple of times, soaking up cheers.

Following news reports that he had fallen ill while returning from Atlanta to Minneapolis, Prince hosted a dance party on April 16 at his Paisley Park compound in Minnesota.
