Prince's death raises numerous questions about prior health

MINNEAPOLIS (AP) — There were no obvious signs of trauma on Prince's body when he was found unresponsive at his home in suburban Minneapolis, and suicide isn't suspected in the superstar musician's death, the local sheriff said today.

Carver County Sheriff Jim Olson said during a news conference that Prince was last seen Wednesday evening, when an acquaintance dropped him off at his sprawling compound, Paisley Park. Olson said Prince was found unresponsive late Thursday morning in an elevator on this first floor of his home after staff members were unable to get a hold of him.

The sheriff noted that the 57-year-old musician was "a very private person," and he said he didn't think it was unusual for the singer to be alone. Olson declined to say who made the initial 911 call, saying that information was private. But he promised to fully investigate the death.

"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," Olson said.
