According to the report, officials have yet to say what role, if any, those medications may have played in his death.
The investigating county sheriff is seeking help from the Drug Enforcement Administration to determine where the medications came from and what prescriptions Prince had obtained, federal law enforcement officials told NBC News.
The legendary singer was found dead alone at his home and recording studio, Paisley Park, on April 21 at age 57. The autopsy was completed the following day and officials determined that there were “no obvious signs of trauma” and “no reason to believe at this point that this was a suicide.”
There was no cell phone in “close proximity” to Prince when his body was found, Carver County Sheriff Jim Olson had said.
According to a transcript released by the Carver County Sheriff’s Office, the 911 call came in from an unidentified male at the residence who said “the person is dead here” and “the people are just distraught.”
The official cause of death will likely not be released for several weeks, Martha Weaver, spokeswoman for the Midwest Medical Examiner’s Office, told The Hollywood Reporter at the time.
NBC News correspondent Pete Williams discussed the report on Wednesday’s NBC Nightly News with Lester Holt.
