NPR:  “Prince's heirs have filed a wrongful death suit against the drugstore chain Walgreens and an Illinois hospital where the singer was treated, then released, the week before his fatal overdose in 2016. Minnesota Public Radio's Matt Sepic reports that attorneys representing Prince's estate allege that Trinity Medical Center, in Moline, Ill., where Prince's plane made an emergency landing on April 15, 2016, failed to appropriately diagnose and treat his overdose.”
