What is it like to learn that your ordinary, loving father is a serial killer? In 2005, Kerri Rawson heard a knock on the door of her apartment. When she opened it, an FBI agent informed her that her father had been arrested for murdering ten people, including two children. It was then that she learned her father was the notorious serial killer known as BTK, a name he'd given himself that described the horrific way he committed his crimes: bind, torture, kill. As news of his capture spread, Wichita celebrated the end of a thirty-one-year nightmare.
