Singer Prince died of opioid overdose: AP citing law enforcement

Tests show music superstar Prince, who was found dead in his home in a Minneapolis suburb in late April, died of an overdose of opioid painkillers, the Associated Press reported on Thursday, citing a law enforcement official.

The cause of death has so far remained undetermined since the 57-year-old singer died on April 21. Federal authorities, including the Drug Enforcement Administration, have been involved in an investigation into Prince's death.

The news follows earlier reports that Prince had the painkiller Percocet in his system when he died.

Prescription opioid medication was also found at the scene of Prince's death, according to a law enforcement source with knowledge of the investigation but not authorized to speak publicly.
