From the clanging of barred doors to the whispers of those who were silenced by cruel treatments, these facilities were meant to heal — but very often harmed, tortured, and killed instead. In this episode, we explore haunted wards, ghostly sightings, and the horrifying realities behind the stories - including lobotomies, electroshock, human experimentation, restraint, and neglect.

Robert Leroy Anderson, infamously known as “The Duct Tape Killer,” was a sexual sadist and murderer whose heinous crimes shocked the Midwest during the 1980s. Anderson kidnapped unsuspecting women, subjected them to brutal torture on a homemade “bondage board,” and ultimately bound and murdered them with duct tape. His horrific acts were fueled by a pathological need for domination and sadistic gratification, blending erotic desire with lethal aggression. This case is both graphic and devastating, so please listen with caution!

Ep143: Snuff Film Killers (Part 1): Wash for us. Clean for us. F*ck for us.

Join our Patreon family! www.Patreon.com/PsychopediaPod You'll get ad free episodes, exclusive content, early access to Girl On Gore, BTS, private group chats, merch discounts, and to guest co-host with Investigator Slater! Few things are rarer, or more terrifying, than a serial-killing duo. And among them, Leonard Lake and Charles Ng (aka The Snuff Film Killers) stand out as one of the most sadistic partnerships in criminal history. In 1983, Leonard built a secret bunker in the hills of California to imprison women as sex slaves and record his twisted “philosophy tape,” which began as a doomsday/survivalist manifesto and eventually spiraled into videotaped kidnappings, assaults, and murders. Alongside fugitive ex-Marine Charles Ng, Leonard Lake unleashed a reign of terror that claimed between 11 and 25 lives, including men, women, and children - some of whose final moments were immortalized on tape. Part 1 of our two-part coverage of The Snuff Film Killers lays the foundation for the nightmare to come, and unpacks the origins, obsessions, and twisted partnership that set the stage for their reign of terror.

EP142: Seven Days of Hell

Join our Patreon family for ad free episodes, exclusive content, early access to Girl On Gore, BTS, private group chats, merch discounts, and to guest co-host with Investigator Slater! www.Patreon.com/PsychopediaPod Welcome to the first episode of Sadistic September. PLEASE LISTEN WITH CAUTION. This case is often described as one of the most sadistic murders in modern UK history. It’s the story of Suzanne Capper, a beautiful 16-year-old girl whose final week on earth was transformed into a living nightmare by six predators who took tremendous joy in inflicting the most horrific forms of torture, degradation, and humilation imagineable. What they inflicted on Suzanne in December 1992 was not "just" physical violence and psychological torment — it was cruelty ritualized. Listener discretion is not just advised, it's essential.

Please SUBSCRIBE to Psychopedia to stay on top of all new content! Join our Patreon family for ad free episodes, exclusive content, early access to Girl On Gore, BTS, private group chats, merch discounts, and to guest co-host with Investigator Slater! www.Patreon.com/PsychopediaPod She doesn’t blink. She doesn’t breathe. She doesn’t need to. Annabelle just waits....a child’s doll with a stitched-on smile wrapped around something patient, ancient, and hungry. For decades, she’s left behind claw marks, bruises, nightmares that crawl out of dreams and into daylight. She’s been blamed for fires, crashes, even death — including the shocking recent passing of investigator Dan Rivera, a man who respected her power more than anyone else. And yet...she’s still touring the country, out of her case, on display for anyone reckless enough to get too close. This isn’t just a haunted doll, it’s a warning. A reminder that some dark energies demand respect — and if you don’t give it, they’ll take it.

EP139: Castration Cult

Please SUBSCRIBE to Psychopedia to stay on top of all new content, bonus episodes, and Investigator Slater’s podcast series, Girl On Gore! Join our Patreon family for ad free episodes, exclusive content, early access to Girl On Gore, BTS, private group chats, merch discounts, and to guest co-host with Investigator Slater! www.Patreon.com/PsychopediaPod What compels a man to slice off his own penis, leg, nipple, and ear…and then turn that compulsion into a business of butchering others who claimed to want the same fate? For Marius Gustavson, a Norwegian man in London, it began with self-castration. From there, his obsession metastasized into a full-blown operation whereby he performed extreme body modifications on dozens of vulnerable men. Marius filmed the mutilations and streamed them on a pay-per-view website, where he also sold severed genitalia to paying customers. His hunting ground was the “nullo” community, composed of individuals seeking genital removal as a radical form of body modification. Many struggled with Body Integrity Identity Disorder (BIID) and turned to Gustavson for help. Instead, they got mutilation, exploitation, and a predator who feasted on their vulnerability — sometimes literally - as Gustavson went on to cannibalize some of the very testicles he cut off. This case is almost too gruesome to believe. But, it isn’t just about mutilation: it’s about control, sadism, consent twisted into theater, and the terrifying lengths people will go to reshape themselves when the wrong hands hold the scalpel.
