(CNN) —  

A day after Prince’s death stunned his fans and fellow musicians, the work of finding out why the music icon died began in earnest Friday.

Prince Rogers Nelson, 57, died Thursday at Paisley Park of unknown causes. The autopsy was conducted Friday at the Midwest Medical Examiner’s Office in Ramsey, Minnesota, but it could be weeks before results are complete, spokeswoman Martha Weaver said.
