The idea for this story came to light during a murder investigation. WTVF uncovered evidence linking the child-abuse death of an 8-year-old boy in the Atlanta area to the teachings of his family's church. The church, located just outside of Nashville, was started by Christian diet guru Gwen Shamblin. Despite Shamblin's denials, the investigation uncovered church tapes that documented how she had instructed her followers to severely discipline their children. Among the tapes: a conference call in which the mother was applauded for locking her child in his room for days.
