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.
The Midwest Medical Examiner's Office finished its autopsy on Prince at 1 p.m. Friday, roughly four hours after it began. The medical examiner's office says that relevant information about Prince's medical and family history is being collected. The agency says it won't release its findings until all information is in, including results of toxicology tests, which could take weeks. The musician's body will be released to his family later Friday.
Prince's death at age 57 has sparked an outpouring of grief from fans, with hundreds gathering outside his studio and in downtown Minneapolis and many more posting remembrances on social networks. Buildings around the country were lit up Thursday night in his signature purple.
