Robin Stone, 17, was a good student with a close-knit family, but then she found out she was pregnant. Robin told her parents that the father was a boy from school she had been dating. On August 27, 1991, Robin was 7-months pregnant when she received a call. She told her mom she was going to help a classmate with homework. It was the last time her mom saw her alive. RobinÂs car was found later that evening near Luburgh Lake in Guernsey County, but there was no sign of her. A missing persons investigation quickly got under way, but it wasnÂt until December 28, 1991, that hunters stumbled upon RobinÂs remains near the lake. Her body was so badly decomposed that they were unable to determine the cause of death. When Sheriff Michael McCauley was elected in 2000, he put a renewed focus on cold case investigations and assigned Detective Sam Williams to re-open RobinÂs case. Detective Williams was around the same age as Robin and was attending high school in the next town when she was killed. He remembers the impact it had on the community and is determined to get justice for Robin and her family.
