BTK is the moniker given to a man who killed 10 people in the Witchita, Kansas, area over a nearly 20-year span. Dennis Rader was a dog catcher, a deacon in his church, and by all appearances, a loving family man. This family man, however, liked to bind, torture, and kill.Joining Nancy Grace today:Dr. Katherine Ramsland - Professor of Forensic Psychology at DeSales University, Author of "Serial Killer: The Untold Story of Dennis Rader The BTK Killer"Darryl Cohen - Former Assistant District Attorney; Fulton County, Georgia -Defense AttorneyCloyd Steiger - 36 years with Seattle Police Department, 22-year Homicide Detective, Author of "Seattle's Forgotten Serial Killer-Gary Gene Grant" Dr. Kendall Crowns - Deputy Medical Examiner Travis County, Texas (Austin)Nicole Partin - Crime Online Investigative Reporter
