Criminal activity William Kessler Lilly was born on March 22, 1962, in Springfield, Ohio. He had one younger brother, and according to Children's services, young William had "hostility toward all women he [came] in contact with." When he was nine, his parents divorced, and he and his brother went to live with his father and step-mother, who they later claimed physically and mentally abused them.
Lilly committed his first crime on March 20, 1980, when he was arrested on charges of animal cruelty. The next year, he moved to Jacksonville, Florida, where he was legally adopted by a man named Al Sapp, which caused Lilly to change his last name to Sapp. In 1988, Sapp married a woman named Karen, and together they moved back to Ohio, settling in Sapp's hometown of Springfield and having three children.

Another man, Jamie Turner (born November 11, 1971), was also convicted for his role in Morrow and Leach murders, and he was sentenced to life imprisonment on November 13, 1998.
