Donald Connor was a New York City Judge. He was the Chief Justice of the Appellate Court, and also worked for The Castelletti Family.
During his time in the employ of The Castellettis, he learned enough to put all of the ranking members to put them away for a long time. This knowledge would eventually be his undoing, as it would make him a target of The Greco Family during the The Castelletti/Greco War of 1919. He was captured by The Grecos, and forced to give over the location of Papa Joe’s Safe House during the war. Judge Connor was rescued from his captors, but would later be executed for his betrayal of The Family’s trust.
