MINNEAPOLIS (AP) — A Minnesota physician questioned by investigators in Prince's death is an experienced family care physician who until recently worked for a Twin Cities health care system.

A search warrant revealed Tuesday that Dr. Michael Todd Schulenberg treated Prince on April 7 and April 20 and prescribed him medications, though it didn't specify which or say whether Prince took them. Prince was found dead April 21 in his suburban Minneapolis home.

Schulenberg was a primary care physician for North Memorial Medical Center, but he has since left the job. A spokeswoman for the health care system declined to elaborate.

Schulenberg earned his MBA in health care recently from the University of St. Thomas in St. Paul. In a 2012 YouTube video posted by the university, Schulenberg said he was then part of the "leadership group" at Ridgeview Medical Center in Carver County.
