Carl Granville was the husband of Alice Cassity, who was oldest sibling of the Cassity family, who came into great wealth through dubious means. Carl and Alice lived on her family's land in Shoshone, Idaho. Sam and Dean Winchester arrived there because they were in search of a hellhound to kill in order to satisfy the first of the Trials. They were fairly certain that since the family's wealth came from oil being struck on their land where no oil had ever been detected before, it was likely that a crossroads deal had been made by someone in the family. When Carl introduced himself to them, he happily described himself as the "trophy husband." They decided that Carl was not the one who would have made a demon deal.
