The AP is reporting that an anonymous law enforcement source says tests confirm the widely held suspicion that Prince died due to an opioid overdose.

UPDATE (2:45 p.m.) A medical examiner in Minnesota has released the results of Prince’s autopsy, which show that he died from an accidental overdose from the painkiller fentanyl.

A link between Prince and painkillers emerged quickly after his death, with TMZ reporting (and records later confirming) that the singer was administered an opioid-blocking Narcan shot when his plane made an emergency landing in Illinois just days before his passing. It’s been reported that Prince was found with painkillers on his person when his body was discovered in an elevator at his Paisley Park compound, and federal authorities (including the DEA) have reportedly been investigating the doctors and pharmacies that may have been treating him.

He was also allegedly scheduled to see an opioid addiction specialist the day that he died.
