After spending four hours in the examination room, Prince’s body will be released to his family later today. The Midwest Medical Examiner’s Office completed the autopsy at 1 p.m. Friday on the 57-year-old singer, who died Thursday, in order to determine the cause of his death. The full report, including toxicology studies, will take several weeks, according to the examiner’s office. In a news conference today, authorities confirmed that Prince was last seen at 8 p.m. on Wednesday night. There were no signs of trauma, and the police do not suspect a suicide. In the wake of his death, some reports have indicated that Prince’s emergency plane landing last week was brought on by the use or overuse of Percocet, a painkiller. The examiner’s office intends to collect relevant information about his family, medical, and social history before the results are released.
