13: Hadden Clark: Disturbing Letters from a Serial Killer

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?For those who want to examine the material directly, the complete letters are available inside UNMARKED: Case Files, our research portal, along with ad-free episodes:https://www.patreon.com/Unmarked_TrueCrimePodcastFollow UNMARKED for additional case material, updates, and short-form analysis: • YouTube: @Unmarked_Podcast • Instagram: @unmarked_podcast • TikTok: @unmarkedpodcast • Patreon: /Unmarked_TrueCrimePodcastIf you want to go deeper into the Charles Manson case, my book Charles Manson: The Last Words documents years researching the story and speaking directly with members of the Manson Family — including Charles Manson himself: https://www.amazon.com/dp/B0GQ6QRVQ7UNMARKED: A True Crime Podcast is hosted by Audioboom.
