A four-hour autopsy was performed on Prince on Friday, but authorities were unable to determine how the music legend died. The results of the autopsy may take several weeks, said officials.
Carver County Sheriff Jim Olson said the musician's body showed no signs of trauma.
"There was no sign of violence," Olson said at a press conference on Friday afternoon, adding that there is no "reason to believe it was suicide."
Prince Roger Nelson, 57, was found unconscious in an elevator on his compound in Chanhassen, a suburb of Minneapolis, at about 9:42 a.m. Thursday, the sheriff said. Although first responders administered CPR, he was not revived. After 24 minutes, authorities pronounced him dead. It is unknown how long he might have been dead.
While the complete autopsy is performed, the results of the toxicology testing will take days to weeks before Prince's manner of death can be confirmed, said officials.
Rumors point to Prince may have overdosed on prescription pain pills, but the sheriff was unable to give any more information.
"I'm not able to confirm that at this time at all," said Olsen. "There have been so many rumors that I've read about. I don't know if I can dispel all the rumors that are out there."
Prince's body was released to his family and retrieved from the coroner's office Friday afternoon, according to Martha Weaver, spokeswoman for the Midwest Medical Examiner's Office.
Prince's funeral detail have not been announced, but the iconic artist's family are gathering to make preparations for the funeral arrangements, according to Radar Online.
Meanwhile, a Petersburg funeral home is planning to host a day of remembrance for Prince.
According to WWBT, Johnson Funeral and Cremation Services, located at 530 South Sycamore Street in the city, will host the tribute on Thursday, April 28 from 12 p.m. to 6 p.m.
