MINNEAPOLIS -- 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 today (Friday), though preliminary findings weren't immediately released.

The Midwest Medical Examiner's Office said it finished its autopsy on Prince at 1 p.m., roughly four hours after it began. Spokeswoman Martha Weaver says relevant information about Prince's medical and family history is being collected. She adds they won't release findings until all information is in, including results of toxicology tests, which could take weeks.

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.
