Summary
Serial killer Hadden Clark is one of the most unsettling figures in modern criminal history — a man whose crimes, confessions, and psychological unraveling have baffled investigators for decades. In this episode of UNMARKED , we examine the case through the original record. Former FBI agents, primary documents, and Clark’s own words reveal a deeply fractured personality and a disturbing window into the mind of a killer. Clark’s writings and statements — including letters he sent from prison — offer rare insight into how he saw himself, his crimes, and the strange identities he adopted along the way. But the deeper question remains: when investigators confront someone like Hadden Clark, what are they really looking at — manipulation, madness, or something far darker?
