Mr. Morton was the husband of Ann Morton.
He was married to Ann Morton, a woman who was possessed by a demon searching for one of Lucifer's Crypts in Lincoln Springs, Missouri; Crowley was having his demons search for the angel tablet. He noticed that his wife had stopped eating and sleeping, and made a scale model of their town in their basement. He also saw her dig numerous holes ten to fifteen feet deep, without breaking a sweat. One day after his wife got home, Mr. Morton saw her eyes turn black. He immediately went to a bar, and when he got home he found her dead.
When Sam and Dean Winchester were investigating a spree of mysterious deaths, they asked Mr. Morton a few follow-up questions on the circumstances surrounding his wife's death. After meeting with the Winchesters, he moved in to his sister's house.
