In 1983, Tommy was just 9 years old when he was removed from his mother's care and placed in a foster home in Thatcher, Utah. One morning, he went out to feed the dog and never came back in the home. His body was found about a month later. With several other children going missing and being murdered in SLC and Pocatello, ID, police wondered if Tommy's case was related. Arthur Gary Bishop denied involvement and Tommy's killer has never been found.
