There has been a lot of speculation about what caused the untimely death of Prince Rodgers Nelson.

Now, fans can finally rest easy in knowing the true nature of Prince’s passing.

Details below…

A law enforcement official leaked the news to the Associated Press that Prince died of a prescription drug overdose.

Tests show that Prince died of an opioid overdose, a law-enforcement official told The Associated Press on Thursday.

The 57-year-old singer was found dead April 21 at his Minneapolis-area estate.

The official, who is close to the investigation, spoke on condition of anonymity because he was not authorized to speak to the media.

The findings confirm suspicions that opioids played a role in the musician’s death. After he died, authorities began reviewing whether an overdose was to blame and whether he had been prescribed drugs in the preceding weeks.

Prince’s death came less than a week after his plane made an emergency stop in Moline, Illinois, for medical treatment as he was returning from an Atlanta concert.

The Associated Press and other media reported that Prince was found unconscious on the plane, and first responders gave him a shot of Narcan, an antidote used in suspected opioid overdoses.

While the superstar had a reputation for clean living, and some friends said they never saw any sign of drug use, longtime friend and collaborator Sheila E. told the AP that Prince had physical issues from performing, citing hip and knee problems that she said came from years of jumping off risers and stage speakers in heels.

At least two doctors’ names have come up in the death investigation being conducted by the Carver County Sheriff’s Office, the U.S. Attorney’s Office in Minnesota and the Drug Enforcement Administration.
