According to a US law enforcement official involved in the investigation of music legend, Prince's death, the icon died of an opioid overdose. Prescription painkillers were in the singer's possession following his death, officials told US media in May.
The official reported the results to the Associated Press. After a post-mortem examination, local officials have no reason to believe that Prince's death was suicide.
As far as the doctor(s) in question, detectives have begun questioning the medical professional who saw 57-year-old Prince twice in the weeks before he died.
BBC reported that a police warrant has also revealed that Dr. Michael Schulenberg prescribed medication to the singer the day before he died.
