The U.S. Attorney’s Office and the Drug Enforcement Administration have joined the investigation into the death of Prince, The Hollywood Reporter confirmed.
“They have agreed to provide federal resources and expertise in our investigation,” Jason Kamerud, spokesman for the Carver County Sheriff’s Office said.
Prince was found dead inside an elevator in his Minnesota home the morning of April 21.
Since that time, the Carver County Sheriff’s Office has been investigating the circumstances surrounding the death of the 57-year-old iconic musician.
Since Prince’s death, there have been multiple reports the artist was struggling with an addiction to painkillers.
On Wednesday, the Star Tribune reported that a California doctor and addiction specialist, Dr. Howard Kornfeld, said he was scheduled to meet with Prince on April 22.
Dr. Kornfeld is an opioid addiction treatment specialist.
William Mauzy, a prominent Minneapolis attorney working with the Kornfeld family, told reporters on Wednesday he feared authorities would charge Andrew with a crime because he had medication on his person at the time of his visit to Prince’s home.
However, the attorney contended his client was immune from prosecution under the “Good Samaritan” law because he was the one who called 911.
The Carver County Sheriff’s Office did not provide any additional details on the investigation.
An autopsy was preformed on Prince. The results from that exam are pending.
Prince was cremated and a private service was held for family and close friends the weekend of his death.
