A law enforcement official close to the investigation surrounding the death of Prince has reported to the Associated Press that the musician died of an opioid overdose. The investigators have also been looking into the doctor who had been prescribing him the pills in the weeks leading up to his passing.

The official was not named and only offered the information on condition of anonymity. Prince was found dead in an elevator in his Paisley Park home in Minnesota in April, and last month it was reported that painkillers were found in his system during the autopsy.

The musician reportedly had to make an emergency landing during a flight home from Atlanta in the week prior to his death, and he was supposedly set to meet with a drug addiction doctor the day after his passing, fueling speculation that he may have succumbed to an overdose of prescribed painkillers. The autopsy reportedly also found that the musician had a dangerously low red blood cell count, pointing to an illness. Representatives for Prince initially reported that the emergency plane landing was due to flu symptoms.

UPDATE:

As TMZ and the Associated Press are reporting, the Midwest Medical Examiner’s has confirmed the findings of their toxicology test that discovered the cause of Prince’s death was an overdose of opioids, specifically the painkiller fentanyl.
