Episode 151: The Cult of Leon Cunningham and the Exorcism of Davey Weilbacher

Cult leader Leon Cunningham preached the end was near, that the Antichrist was coming and all must repent to ensure their names were written in blood in the Book of the Lamb, otherwise be doomed to eternal damnation and hell fire.

Believing the devil had infiltrated their group, in 1976 Leon and his ragtag cult performed a violent exorcism on three-year-old Davey Weilbacher that ended in horrible tragedy.
