Minneapolis, MN  (AP)  Authorities say it could take days or even weeks before the public learns the cause of Prince’s death.
An autopsy is scheduled for Friday morning, a day after the 57-year-old music superstar was found dead at his studio compound in suburban Minneapolis.

A spokeswoman for the Midwest Medical Examiner’s Office says the agency doesn’t plan to release any preliminary information until autopsy results are completed.

Spokeswoman Martha Weaver says she expects the process will take days or even weeks for tests to be completed. She also says no preliminary results will be released by her office, and that the office will wait to release findings when all the information is in.

Once the physical autopsy is finished, Prince’s body will be released to a designee of his family.
