Cops Are Investigating Whether Prince's Death Was an Overdose

Police have launched an official investigation into how prescription medication may have played a role in Prince's untimely death earlier this month, as the Associated Press reports.

A law enforcement official briefed on the investigation told the AP investigators are looking into whether a doctor was prescribing the musician drugs in the weeks before he was found dead at Paisley Park in Minneapolis. They're also said to be looking into whether a doctor was on the plane that made an emergency landing in Moline, Illinois, six days before his death.

TMZ previously reported that Prince's plane had to make that emergency landing after the star allegedly overdosed on Percocet. The official confirmed to the AP this week that Prince was, in fact, administered a "save shot" of Narcan, which is often used in cases of opioid overdoses, on the tarmac in Moline.

The pop giant's autopsy results are expected to be released within the next three to four weeks. Until then, investigators are probing what kinds of drugs may have been in Prince's home, recording studio, and plane, leaning on the search warrant issued after his death.
