Harley Jorgeson was the psychotic husband of Stacey Jorgeson and uncle to Emily Jorgeson.
Background
He and his wife ran a gas station in a small town in Indiana. The intended sacrifice would stop there and Harley would spot a "problem" with the car and "fix" it. They would also give directions to the couple where to head next. They captured Dean Winchester and tried to sacrifice him along with Emily Jorgeson to their god. After Dean and Emily escaped, Harley and his wife were killed by the pagan god.
