MINNEAPOLIS – A law enforcement official tells The Associated Press that investigators are looking into whether Prince died from a drug overdose and whether a doctor was prescribing him drugs in the weeks before his death.

The official said that among the things investigators are looking at is whether a doctor was on a plane that made an emergency landing in Illinois less than a week before Prince died.

The law enforcement official has been briefed on the investigation and spoke on condition of anonymity because he was not authorized to speak to the media.

The official says investigators are also looking into what kind of drugs were on plane and at his house in suburban Minneapolis.

A rundown of calls to police from Prince’s Paisley Park estate in recent years is dominated by incidents like suspicious activity, trespassers or tripped alarms.

The five-year summary released Thursday by the Carver County Sheriff’s Office also includes four calls classified as medical.

One of those came on April 21, the day the 57-year-old musician was found unresponsive and later pronounced dead.

The sheriff’s office didn’t immediately respond to a request for incident reports on the other three calls.

Two of those calls came in the past year, when Carver County authorities say they received no medical calls to help Prince himself from his suburban Minneapolis home and recording studio complex.

The last call classified as medical came on Oct. 23, 2013.

Authorities investigating Prince’s death found prescription opioid medication on him and in his Minnesota home, a law enforcement official told CNN.

The pills are commonly used to treat pain, and investigators have brought in the U.S. Drug Enforcement Administration to help with the case, the source said Wednesday.

Investigators believe a health scare about a week before Prince’s death, which caused an unscheduled landing of his plane in Illinois, was likely the result of a reaction to the pain medication, the official said.

The pilot told air traffic control that a passenger, later known to be Prince, was unresponsive.

Prince was treated for a potential overdose of pain medication, the official said.

The singer was reportedly rushed to a hospital in Moline, Illinois. His publicist, Yvette Noel-Schure, later said he returned home and was fine.

Prince was 57 when he died last week at his home in a Minneapolis suburb.

He was found unresponsive Thursday in an elevator at Paisley Park, his home and studio in Chanhassen, Minnesota. Paramedics performed CPR but were unable to revive him.

Carver County, Minnesota, Sheriff Jim Olson said there were no obvious signs of trauma on Prince’s body when he was found.

Prince was last seen alive was at 8 p.m. Wednesday when he was dropped off at Paisley Park, the sheriff said. He was alone in the complex when he was found, which Olson said was not unusual given the performer’s private persona.

Dr. Sanjay Gupta, CNN’s chief medical correspondent, said opioid medications are widely used.

“There are plenty of people out there who get legitimate pain pills for legitimate pain concerns and they do well,” Gupta said. “They come off of them with no problem, but there’s a certain percentage of people who do become addicted to these, meaning they have to keep taking them.”

He added it’s uncertain that anything similar had happened with Prince.

Investigators are still awaiting results of autopsy and toxicology tests for further understanding of why Prince died.

The Midwest Medical Examiner’s Office in Ramsey, Minnesota, performed the autopsy on the much-loved musician Friday.

Dr. A. Quinn Strobl finished the procedure in four hours, according to the office, but Strobl won’t declare what caused Prince’s death until after the office gathers all the relevant details. Doing so will take weeks.

On Thursday, a Carver County judge sealed a search warrant for Prince’s home and any evidence coming from it, according to court documents.

A prosecutor and sheriff’s deputy who requested the action said disclosure of the details could “compromise this law enforcement investigation,” a sheriff’s deputy and prosecutor said in requesting the action.
