UPDATE: The Midwest Medical Examiner's Office has released the results of Prince's death investigation. His death is listed as "fentanyl toxicity," and was ruled accidental. According to the National Institution on Drug Abuse, "Fentanyl is a powerful synthetic opiate analgesic similar to, but more potent than morphine. It is typically used to treat patients with severe pain, or to manage pain after surgery."
The report also listed the 5'3" star's build as "petite" and weight as 112 lbs. Scars were noted on his left hip and right lower leg.
He was wearing a black cap, shirt, pants and socks, as well as a grey undershirt, at the time of his death.
Law enforcement officials have revealed Prince's cause of death to the Associated Press.
The sources say that the singer died of an opioid overdose.
News of the overdose comes ahead of the release of Prince's official toxicology reports.
Last month, the Minneapolis Star Tribune claimed that Percocet, an opioid, was found in the 57-year-old star's system when he passed away.
It was also recently reported that Prince was seeking help for his alleged drug addiction before his death. Dr. Howard Kornfeld of Recovery Without Walls treatment center was scheduled to meet with Prince at Paisley Park on Friday, April 22, just one day after the music legend was found dead in his elevator.
Kornfeld's son Andrew, an addiction specialist, had flown in from California and was supposed to meet with Prince first, on the day Prince's body was discovered. Andrew is the person who reportedly called 911.
Less than a week before he died, Prince reportedly overdosed on Percocet while on a plane. TMZ reports that EMTs had to administer a so-called "save shot” in order to revive him.
