Overview
- The three-episode docuseries premiered Monday, July 13, 2026, and centers on Alex Campbell’s 2024–2025 sociology class at Elizabethton High School in Tennessee investigating the decades-old Redhead Murders.
- Students working with the Tennessee Bureau of Investigation helped identify previously nameless victims and produced a suspect profile that the TBI later linked to a deceased truck driver, but no charges followed because the suspect died before prosecution.
- The series highlights the long-identified case of Tracy Sue Walker, who went missing in 1978 and whose Elk Valley remains were named in 2022 through forensic genetic genealogy, a technique that matches DNA to relatives to establish identity.
- The class ran a high-profile public-awareness campaign—yard signs, postcards, a QR-code car wrap, an awareness website and aerial messaging—that TBI says reached more than 24 million views and generated new tips for investigators.
- Murder 101 frames the work as restorative and educational, showing how naming victims and sustaining public pressure can keep cold cases alive even when time, degraded evidence and a deceased suspect limit the prospect of legal closure.
