People Editorial Guidelines Published on April 19, 2018 02:25 PM Share Tweet Pin Email No criminal charges will be filed following the investigation into Prince‘s sudden death. Prosecutors in his home state of Minnesota made the announcement Thursday regarding the outcome of the investigation into the music legend’s drug-related passing on April 21, 2016. In a press conference, Carver County Attorney Mark Metz revealedno criminal charges can be filed because of insufficient evidence. “We simply do not have sufficient evidence to charge anyone with a crime related to Prince’s death,” Metz said in the press conference, held at 11:30 AM local time in the Minnesota town of Chaska. BERTRAND GUAY/AFP/Getty During the announcement, the attorney revealed that Prince was addicted to opioid painkillers; while the pills found in his Paisley Park compound were labeled as Watson 853 (or Vicodin), the medication was counterfeit and laced with the potent and addictive drug fentanyl. “In all likelihood Prince had no idea he was taking a counterfeit pill that could kill him,” said Metz, who noted there is no evidence the counterfeit drugs Prince ingested were prescribed by a doctor or that there was “sinister motive to murder Prince.” During the press conference, Metz revealed that Dr. Michael T. Schulenberg — a local physician who prescribed painkillers to Prince’s assistant, Kirk Johnson, knowing the musician would be using them — “is being held accountable.” Per Metz, Schulenberg reached a civil settlement out of court with U.S. Attorney’s office in Minnesota; he was ordered to pay a $30,000 fine and will also be monitored for two years by the U.S. Drug Enforcement Administration.

Prince Had ‘Exceedingly High’ Amount of Fentanyl in His Blood When He Died A toxicology report from the late singer’s autopsy released last month states the concentration of fentanyl in his blood was 67.8 micrograms per liter according to the Associated Press. Fatalities from the drug — which is estimated to be 80 times as potent as morphine and hundreds of times more potent than heroin — have been documented in people with blood levels ranging from three to 58 micrograms per liter. “The amount in [Prince’s] blood is exceedingly high, even for somebody who is a chronic pain patient on fentanyl patches,” Dr. Lewis Nelson, chairman of emergency medicine at Rutgers New Jersey Medical School, previously told the AP. In addition, the toxicology report states the level of fentanyl in the Prince’s liver was 450 micrograms per kilogram and notes that liver concentrations greater than 69 micrograms per kilogram “seem to represent overdose or fatal toxicity cases.” LAMedia Collection/Sunshine/Zuma Prince was 57 when he was found dead in his Paisley Park compound on April 21, 2016. The autopsy was completed the next day. In June 2016, the Midwest Medical Examiner’s Office revealed the singer died of an accidental overdose of fentanyl.
