On Tuesday morning, October 31st, John Hagedorn died peacefully in his home with his family at his side. We deeply mourn the loss of our dear friend and colleague. John had a long-time affiliation with the Great Cities Institute and in 2016 was given the official title at the Institute of James J. Stukel Senior Faculty Fellow. He was also Professor Emeritus from the Department of Criminology, Law, and Justice. We offer our deepest condolences to his wife, Mary, and to his family. We will miss John beyond words, but we will never forget him. May he rest in peace.
