Prince’s best friend could be key in death investigation

According to a search warrant, detectives interviewed Kirk A. Johnson — a former Prince drummer and current manager of the singer’s Paisley Park estate — following the performer’s unexpected death last month. The court document, obtained by the Los Angeles Times, discloses that police seized Prince Rogers Nelson’s medical records from a Minneapolis-area hospital in early May. Investigators were particularly interested in files involving a family-medicine doctor who had treated Prince in the weeks before the singer was found dead April 21 in a Paisley Park elevator.
