Questions linger about Prince's choice of local doctor

MINNEAPOLIS — If Prince was seeking help for a problem with prescription drugs, it would make sense for him to turn to a California addiction specialist known for new ideas on treatment. [...] in the weeks before Prince’s April 21 death, he met twice with Dr. Michael Todd Schulenberg, who worked at a Minnetonka, Minn., clinic a few miles from Prince’s Paisley Park studio and home, according to search warrant documents released Tuesday. The Star Tribune, citing a source with knowledge of the investigation, previously reported that Prince had been receiving treatment for withdrawal symptoms from a doctor who previously worked with Prince’s longtime friend Kirk Johnson.
