An autopsy is scheduled for Prince after he was found dead at his studio compound in suburban Minneapolis.

The Midwest Medical Examiners Office in Ramsey, Minnesota, tweeted that it will perform the autopsy Friday. Officials haven't released a cause of death.

Authorities said deputies who were summoned to a medical emergency Thursday found Prince in an elevator, unresponsive. They say CPR failed.

Prince's death at age 57 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.
