Prince may have died hours before he was found

Prince may have died at least six hours before his body was found, and was given fluids intravenously the day before he died, The Minneapolis Star Tribune reported, as new details emerged about the singer's final hours.

Autopsy and toxicology results have yet to be released, but the Star Tribune on Saturday cited sources as saying that Prince grew increasingly agitated following his emergency for an opioid overdose on April 15, despite putting on a calm appearance.

Citing sources with knowledge of the investigation, the newspaper said a responding paramedic told staff, law enforcement officers and others at the scene that Prince may have been dead for at least six hours before he was found unresponsive in an elevator at his Paisley Park complex on April 21.

Authorities have said that the pop star was alone at the time of his death, and that they don't believe suicide or foul play was involved.

Prince's agitated state led one of his staff members to call someone in New York who had recently worked with the musician, seeking advice, on April 20, according to the Star Tribune.

Later that day, Prince was given an intravenous treatment at a local hospital, the report said, citing a source with knowledge of the investigation.

The newspaper said it was unclear whether Prince was given the intravenous treatment before or after a doctor treating him for withdrawal symptoms made a house call on the evening of April 20.
