Philadelphia 'House of Horrors' Search Intensifies for Seven Missing Women
Authorities are deploying forensic teams, sniffer dogs, and chemical tests in a sprawling investigation linked to a deceased adult film maker and author suspected of serial killings.
Law enforcement officials have intensified their search of a Philadelphia property, dubbed a "house of horrors," as they look for evidence connecting the home to seven missing women. The investigation centers on the former residence of Raymond "RC" Horsch, an 82-year-old adult film maker and author who died last year and is suspected of serial killings.
Investigators have conducted multiple searches of Horsch's two-story brick house in the Olney neighborhood. During an initial sweep, police reportedly discovered over one million images and videos depicting sex, drug use, and at least one snuff film. Authorities have identified at least 58 potential victims within this digital evidence, with at least five women appearing lifeless or unconscious in the footage.
The FBI joined the investigation on Tuesday. On Friday, authorities brought in Cache, a Philadelphia Police Department electronic-sniffing Labrador retriever, along with other K-9 units. Cache is trained to detect hidden data storage devices by sensing the oils on their surfaces. Investigators are also planning to use luminol, a chemical that reacts with iron in blood to emit a temporary blue glow, on Monday evening. This method is intended to detect any trace of blood, even if it has been cleaned.
Heavy equipment is scheduled to be brought to the property on Tuesday to aid in digging for potential evidence. As of Sunday, no bodies had been found at or near the house, and it was not announced if Cache's search yielded additional digital evidence.
Missing women believed to be connected to Horsch include Gabrielle Amarando, Maribel Fresses, and Nicole Fusaro. Horsch's ex-wife, Amy McHale, and another woman associated with him, Blair Tonzelli, also remain unaccounted for. Some footage reportedly shows Horsch strangling Nicole Fusaro.
Ten other individuals seen in the recovered evidence reportedly died of overdoses in various Philadelphia locations. Sixteen other alleged victims were found alive but were reportedly uncooperative with investigators, with three refusing to speak to authorities. Efforts are underway to interview 25 additional identified alleged victims.
The investigation was initiated in June when a park ranger encountered Eugene Horsch, the son of the deceased suspected serial killer, and a woman in a vehicle within Independence National Historical Park. The woman identified herself as Blair Tonzelli, who had been reported missing in 2023.
This encounter led authorities to search Eugene and his father's home, where the extensive collection of disturbing videos and images was found. The residence also contained an illegal firearm, ammunition, chemicals, a counterfeit FBI badge, a marijuana cultivation setup, and five urns with cremated remains. Eugene Horsch is currently detained on drug and gun charges. His attorney has expressed concern that the police activity will lead to the destruction of the house.
