    EP206: Inside Philadelphia's House of Horrors: The R.C. Horsch Case
    Oct 21 2026
    The Olney House of Horrors in Philadelphia has recently become the center of a truly disturbing investigation into Raymond Horsch, a pornographic filmmaker suspected of harboring secrets far more sinister than anyone could have imagined. Behind the walls of his home, investigators uncovered a disturbing collection of sexually explicit photographs and videos, raising horrifying questions about whether some of the violence he filmed was staged- or whether countless women were actually murdered on camera. With seven missing women reportedly linked to the investigation, allegations of snuff films, and authorities searching the property for possible human remains, the line between sexual fantasy and sadistic reality has become terrifyingly blurred. Was Raymond Horsch simply a man with a depraved imagination, or was Philadelphia's so-called House of Horrors hiding evidence of a serial killer?FOLLOW/SUBSCRIBE wherever you are listening!Join our Patreon family!

  • EP205: The Suitcase Killer: Sarah Boone

    EP205: The Suitcase Killer: Sarah Boone
    Oct 14 2026
    Sarah Boone, infamously known as “The Suitcase Killer,” zipped her boyfriend inside a suitcase, laughed as he desperately begged to be let out, and recorded his final pleas for help on her cellphone. What she later described as an innocent game of hide-and-seek ended with 42-year-old Jorge Torres Jr. suffocating to death inside a suitcase in their Florida apartment. As investigators uncovered chilling cellphone footage, bruises and cuts on Jorge's body, and a deeply troubled relationship, Sarah launched into a years-long legal circus involving countless attorneys, outrageous courtroom demands, and a defense that seemed almost too bizarre to believe. In the end, the most damning witness against Sarah Boone....was Sarah Boone herself.PLEASE VOTE FOR ME in the 2026 Signal Listener's Choice Award!

  • EP204: The Genesee River Killer: Arthur Shawcross

    EP204: The Genesee River Killer: Arthur Shawcross
    Oct 7 2026
    Arthur Shawcross, the “Genesee River Killer,” murdered two children and after serving just over 14 years in prison, he was released back into society. Then women started disappearing. Their bodies began turning up around Rochester, New York, many near the Genesee River, as police searched for a serial killer they had already caught once before. By the time investigators finally connected the murders to Shawcross, he had been free for less than two years and 11 more people were dead. This is the horrifying story of a convicted child killer who was released from prison, the victims who paid the ultimate price, and how one devastating second chance allowed Arthur Shawcross to become one of New York’s most notorious serial killers.PLEASE VOTE FOR ME in the 2026 Signal Listener's Choice Award!

I saw this title and the two hosts and I admit that I thought oh this is a 'Joe Rogan does true crime' right wing podcast. I was ABSOLUTELY proved wrong almost instantly as the intelligently researched crime stories, expertly delivered by investigator Slater and interjected with thoughtful, considered and empathetic remarks from the admittedly 'jacked' Tank Sinatra. That's not to say there isn't humour and 'in jokes' that when you know, you know. Tanks love of hip hop and obviously meme culture comes through in the episodes. Brooke Slater (an actual investigator in her day job working with human trafficking among other things) has a real knack for researching all the key elements of a case and humanising victims as well as her 'pop quizzes' that she posits to Tank and the listener which is a novel feature i personally love. overall an excellent True Crime podcast that only gets better as it goes on and I think will shine through as one of the top of it's genre. Crimedy Chaos Completed supremely.

It is a doozy, great true crime comedy cohorts.
