Carver County Attorney Mark Metz said Prince had suffered from pain for years and was addicted to pain medication.
The news comes as the Minnesota doctor who prescribed opioid painkillers to Prince a week before the musician died has agreed to pay out $30,000 United States dollars settlement over a federal civil violation.
The county attorney says despite Schulenberg's decision to issue an illegal prescription there is no evidence the Percocet prescribed had anything to do with Prince's death, or that either Schulenberg or Johnson has ties to the counterfeit Vicodin that killed him. They also showed Schulenberg and Kirk Johnson, who was Prince's close friend and bodyguard, were the main subjects of the investigation.
Schulenberg's attorney Amy S. Conners said in a statement the doctor had made the agreement "in order to avoid the expense, delay, and unknown outcome of litigation". "Prince's death was a tragedy that few could experience more deeply than Kirk Johnson".
But Metz said that the motivation was more to protect Prince's privacy and that there was no evidence that Schulenberg gave the star fentanyl.
Prince died on April 21, 2016, from an accidental overdose of fentanyl, a synthetic opioid. Prince was found unconscious on the plane and was given two doses of naloxone, an antidote used to reverse suspected opioid overdoses. Schulenberg's attorney has disputed that. The day before he died his team reached out with an urgent request for help to an opioid addiction specialist, according to CNN.
Prince was renown for his clean living, hosting several sober parties at his Paisley Park home/recording studio.
Hurricane-ravaged Puerto Rico Again?
Coto noted that around 40,000 power customers on the island still remain without normal electrical service due to the hurricane. Puerto Rico received another blow Wednesday when a blackout hit the entire island leaving millions in the dark once again.
Authorities alleged Schulenberg, a family physician who saw Prince twice before he died, illegally prescribed an opioid to Prince in violation of the Controlled Substances Act.
Associates at Paisley Park told investigators that Prince was recently "going through withdrawals, which are believed to be the result of the abuse of prescription medication", according to an affidavit.
On Thursday, Warner Bros. records and the singer's estate released the original version of Prince's 1984 song "Nothing Compares 2 U", along with a video featuring rehearsal footage, that has never been seen before, of the singer and his band The Revolution practicing their choreography that year.
As the state of Minnesota ends its investigation into Prince's death without criminal charges, federal authorities say they haven't gotten any credible evidence to support charges either.
It was Andrew Kornfeld who discovered Prince's unresponsive body the morning of April 21, 2016, when he arrived at Paisley Park for a meeting on how to proceed with his treatment. Johnson then called Schulenberg on April 14, asking the doctor to prescribe a pain medication for Prince's hip.
"Despite "intensive" investigation", Metz said law enforcement was unable to determine who provided the counterfeit Vicodin laced with fentanyl that killed Prince.
