The coroner’s report has confirmed that Prince died of an overdose of Fentanyl. The drug is a powerful painkiller that is stronger than morphine. According to the report, the drug was “self-administered.” Long-time friend and colleague Shelia E. said that he had been in pain for years and had a problem with his hip. He had hip replacement surgery in 2010. Prince had been rumoured to have a problem with Percocet, which he took for the pain.
