Murder 101

A decades-old unsolved Tennessee case stumps top detectives until a high school sociology class breaks it wide open.

There's a voice that has lived inside the case for 40 years; Linda Schacke, the only known survivor of suspected killer Jerry Johns, agrees to speak with the class.

Back home, the students are restless; if the killer isn't clear, maybe the mission can be; Campbell challenges them to transform their research into action, to bring awareness back to the community that forgot.
