Today’s report from the Midwest Medical Examiner’s Office comes more than a month after the rock icon was found dead at age 57 at his Paisley Park mansion.
The single-page report said Prince “self-administered fentanyl,” referring to a synthetic opioid many times more potent than heroin.
The report was signed by Quinn Strobl, the office’s chief medical examiner.
Earlier Thursday, the Associated Press reported a law enforcement official who is close to the investigation said that tests show Prince died of an opioid overdose. The official said the autopsy results would be released tomorrow.
Investigators have been reviewing whether an overdose was to blame and whether Prince was prescribed drugs in the weeks before his death.
