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.

 Today we bring you a truly heart-wrenching story of what is possibly the most brutal crime in modern English history, a murder that sent shock waves throughout the United Kingdom and the world, not just because of the horror and sadism involved, but because of the innocence of the victim, who was just 17 years old. A schoolgirl who found herself in a romantic relationship with a sadistic killer, a story that is every parent’s worst nightmare.

It's the story of the murder of Kelly Anne Bates at the hands of the horrible monster James Patterson Smith.

Listener discretion is advised.
