5 Missing Women Traced to the House of a Serial Killer - Philadelphia Cold Case Solved

When investigators raided a boarded-up rowhome at 417 West Chew Avenue, they walked into a literal house of horrors. Detectives uncovered fake DEA badges, obliterated firearms, over a million digital files of unimaginable violence, and a terrifying basement "laboratory" equipped with 55-gallon drums and highly corrosive chemicals. It was a makeshift apparatus designed for "wet cremation"—a method used to completely dissolve human bodies so no physical trace is ever found. ​But the most enraging part of this investigation isn't just the man they arrested; it is the man who raised him. Raymond RC Horsch, a twisted photographer who spent decades preying on vulnerable women in Philadelphia's Kensington neighborhood, orchestrated the horrors inside that home. In 2014, Raymond literally self-published a memoir detailing exactly how he strangled victims and disposed of them in chemical drums. ​Tragically, the system ignored the glaring red flags for over a decade. Raymond died a free man in 2025, just one year before investigators finally discovered the digital graveyard he left behind. ​In this episode of Vanished Women and Children, we break down the unraveling of the Philadelphia House of Horrors, the systemic failures that allowed a predator to hunt in plain sight, and the heartbreaking stories of the five missing women connected to this address. ​Video Chapters: ​0:00 - A Terrifying Traffic Stop at the Liberty Bell 01:54 - Inside the West Chew Avenue House of Horrors 06:15 - Who Was Raymond RC Horsch? 11:25 - The Published Memoir of a Serial Killer 17:43 - The Missing Women of Kensington 24:29 - What Investigators Found on the Hard Drives 30:26 - Eugene Horsch and the Blame Game 36:36 - How the System Failed These Vulnerable Women ​Join the Discussion: How could a man with a federal criminal record literally publish a book detailing how to dissolve bodies in a basement, while women connected to his address were actively going missing, and no one investigated him?
