For nearly two decades, Wichita, Kansas, was plagued by a killer who left a bizarre calling card in the treatment of his victims. Between 1974 and 1991, ten people were bound and tortured before eventually being killed, hence the killer’s nickname, the “BTK killer.”
Dennis Rader was arrested in 2005 and openly admitted he was behind the BTK killings. After his arrest, NBC’s Dateline gained access to an exclusive interview with Rader by Harvard-trained forensic psychologist Robert Mendoza. During their discussion, Rader explained his obsession with killing and his inability to control his actions once his mind had fixated on a victim.
Despite pleading guilty to the charges, Rader shies away from blaming himself for the killings, instead choosing to point the finger at potential demons that dwell within him. Rader is currently serving ten consecutive life sentences.
