Los Angeles, Jun 2 (EFE).– U.S. musician Prince died of an opioid overdose, according to the results of the autopsy performed on April 22.

The Midwest Medical Examiner’s Office, located in Ramsey, Minnesota, said the artist died from an accidental overdose of fentanyl, adding in its report that the drug was self-administered.

The artist had been hospitalized six days before his death after overdosing on Percocet, an opioid that is a combination of oxycodone and acetaminophen, the celebrity gossip Web site TMZ reported at the time.

On April 20, a day before Prince passed away at his Paisley Park recording studio and residence in Chanhassen, Minnesota, at the age of 57, Prince’s representatives had contacted Howard Kornfeld, an expert on opioid addictions, seeking urgent medical help for the artist.

Kornfeld could not travel to meet with Prince until April 22 so he sent his son, Andrew Kornfeld, a pre-med student in his 20s, to the residence in his place, attorney William Mauzy, who represents the two men, said in a press conference in Minneapolis on May 4.

Mauzy said Andrew was present at Prince’s home on the day of his death, April 21.

Members of Prince’s staff found the musician unconscious in an elevator and one of them began shouting, Mauzy said, adding that Andrew heard the noise and went to the elevator, where he found Prince to be unresponsive.

Mauzy said at the press conference that Andrew was the person who called 911 to report a medical emergency at Paisley Park.

He emphasized that the younger Kornfeld’s actions were appropriate for a medical emergency and added that people who request aid via 911 for individuals who have overdosed acquire “immunity” for certain actions surrounding their attempts to help the victims.

Andrew Kornfeld was in possession of a small amount of buprenorphine at the time of Prince’s death, but Mauzy said he never administered that drug to the musician.

Local police in Carver County launched a criminal investigation shortly after Prince’s death, a probe in which U.S. Drug Enforcement Administration agents also are involved. EFE
