Kerri Rawson says that when the FBI informed her that her father, Dennis Rader, was the notorious serial killer BTK, she was convinced they had the wrong man. Rawson says her father was a churchgoer, Boy Scout leader and her best friend, and there was no way the man she loved was binding, torturing and killing innocent people while being a hands-on dad at home.
