MINNEAPOLIS — Several news organizations are reporting that prescription drugs were discovered with Prince when he was found dead in his Paisley Park home.

ABC, NBC, CBS, and CNN, citing unidentified law enforcement sources, have reported that prescription painkillers were found on the 57-year-old Prince and in his home. The Star Tribune, also citing unnamed sources, reported that prescription pills were found but that it wasn’t clear whether they were prescribed to Prince.

Prince died April 21. Autopsy results aren’t expected for three to four weeks.

Several outlets also reported Minnesota investigators have asked the U.S. Drug Enforcement Administration for help.

Carver County Deputy Sheriff Jason Kamerud discounted those reports late Wednesday, saying the DEA “is not part of the investigation at this time.” A DEA spokesman in Chicago hasn’t responded to messages.
