"Monster: BTK"

Known by the moniker, BTK – Bind Torture Kill, his notoriety was bolstered by the taunting letters he sent to police, and the chilling phone calls he made to media outlets. BTK's identity was finally revealed in 2005 to the shock of his family, his community, and the world. He was the serial killer next door. From Tenderfoot TV & iHeartPodcasts, this is 'Monster: BTK'.
