Karla Brown was the youngest of three girls in the Brown family. After many failed relationships, Karla became engaged to Mark Fair. The couple began moving into their dream home in June 1978. On the morning of June 20, Mark left for work and Karla remained at home. When Mark and a friend returned home that evening, they found Karla dead. The condition of Karla's body told investigators that she was a victim of sexual assault; she had resisted, struggled, and was killed. The Police questioned Paul Main and John Prante, who lived across the street. They were considered low-level suspects. After a second autopsy, they were able to re-examine bite marks. A Computer enhancement gave a better view of the bite marks, and the science of forensic odontology identified John Prante. On July 15, 1983, five years after the murder, Prante was found guilty and sentenced to 75 years in prison.
