On November 13, 2022, four students from the University of Idaho are brutally stabbed to death in an off-campus house. After a lengthy investigation and cross-country manhunt, a Ph.D. student from a neighboring university is charged with the crimes. As it turns out, the 28-year-old was majoring in criminology, studying the behavior of killers like the ones he would later be accused of becoming. Did he use his skills to become a real-life Dexter? Were the Idaho victims his first, or was a serial killer hiding in the midst? The producers of The Piketon Massacre explore all sides of the shocking crime in pursuit of the truth.
