Six of Prince’s siblings are suing Iowa Health System, UnityPoint Health, Walgreens, North Memorial Healthcare and Minnesota physician Michael Schulenberg.
The lawsuit alleges that in the weeks immediately preceding Prince’s death, he received professional health care services from the defendants identified by the suit.
It also outlines the dates in which Prince visited each of the facilities or people mentioned and then alleges that “all of the defendants had an opportunity and duty during the weeks before Prince’s death to diagnose and treat Prince’s opioid addition and to prevent his death. They failed to do so.”
