In this episode of The Evidence Locker, we delve into the shocking 1971 familicide that forever altered the quiet suburb of Westfield, New Jersey. Accountant and devout Lutheran John Emil List murdered his wife, mother, and three teenage children in their grand Victorian mansion, leaving a meticulously staged crime scene and a five‑page confession letter to his pastor. After vanishing, List assumed the alias Robert Peter “Bob” Clark and eluded capture for 18 years, living a seemingly ordinary life in Colorado and later Virginia.
