Killen was a small community in North Georgia with a small wooden sign on the outskirts of town: Welcome to Killen a little piece of Heaven. Those words rang true for most of Killen's first 200 years. But there was one exception. It was the time that Killen lived up to its name and a little piece of heaven became...a little piece of hell. When Thomas Dalton was 13-years-old, a string of murders in a North Georgia received unwanted national attention.
