Who killed Janice Potter?

It was a typical Tuesday night. Janice Lynn Potter, 24, came home from work on April 15, 1986, and ate dinner at her home on Talister Court in Rossville. At the time, Janice was two months pregnant. After dinner, Janice went to the basement living room to watch television. But since the basement wood stove was on, it was quite warm. Before her husband left for his night classes in College Park at 6 p.m., Janice asked him to crack the sliding glass door open so some of the heat could come out.
