On Februrary 11, 1987, 15-year-old Tim Masters walked through the field behind his house on the way to the school bus stop in Fort Collins, Colorado. There he discovered the body of Peggy Hettrick who was lying face up with her shirt pulled up and her pants pulled down around her knees. She had been stabbed and mutilated. The investigation that would follow would span over a decade and be bungled so severely that it saw an innocent man behind bars. Many suspects, some more obvious than others, would come to the surface. Will we ever know who killed Peggy Hettrick?
