Debbie Fijan was just 10 years old when she was stabbed 19 times and left in an ice-crusted ditch on Lies Road near West Chicago on Feb. 11, 1966. The fifth-grader had stayed after school for a basketball game and was waiting for her mother to pick her up when she disappeared. The last person to see her, her Benjamin Elementary School teacher Loren Schofield, was charged with the killing, but the judge soon realized the evidence didn't match up. The case has been unsolved for 50 years.
