Authorities, including the FBI, have returned to a Philadelphia residence to continue the investigation into a possible serial killer connected to the cases of at least seven missing women. This ongoing probe has already uncovered concerning materials such as “snuff” films and urns filled with ashes.
Recent images depict heavy machinery in the backyard and investigators, equipped with protective gear, working diligently on the property. They’ve erected tents and used tarps to cover certain areas while officials in various forms of protective apparel methodically move in and out.
One investigator was noted for carrying what appeared to be a chemical-spraying device. Additionally, a crime scene photographer was observed on site earlier this week.
The property is surrounded by police tape and officers remain on alert. Joseph Giacalone, a retired NYPD cold case sergeant, remarked on the extensive nature of the investigation. He noted the unusually high number of crime scene technicians involved, which generally reflects the complexity and breadth of evidence in such cases.
Recently, police have made multiple visits, retrieving boxes of evidence, including one labeled “glass vials.” A spokesperson for the Philadelphia Police Department, while refraining from divulging specifics, acknowledged the active and ongoing nature of the investigation.
Investigators are diligently sifting through evidence and exploring leads, although specifics regarding their findings remain undisclosed. Raymond “RC” Horsch, a renowned producer of BDSM-themed content, passed away last year. His son, Eugene Horsch, was arrested earlier this year after being found with a woman carrying an ID connected to one of the missing women.
Previous searches at the home yielded videos and images of four of the missing women, as well as containers of chemicals linked to the house’s water system. In discussions about investigative practices, retired FBI supervisory agent James Gagliano pointed out that discoveries often lead to further scrutiny and repeat visits to crime scenes.
Currently, only a few of the missing women have been publicly named. The police have confirmed that Maribel Fresses, 26, who disappeared in 2018, and Gabrielle Amarando, 27, are two of the cases tied to the investigation. During Eugene Horsch’s detention, a woman accompanying him had the ID of Blair Tonzelli, 38, who was last spotted in February 2023.
Two other women, one being Horsch’s ex-wife, Amy McHale, 54, who vanished in 2016, and Nicole “Nikki” Fusaro, 34, missing since 2019, have also been identified in connection with the case. There’s a recognition that dozens of other individuals have been identified from the recovered images, but no arrests have occurred as the investigation unfolds.
While previous excavations have focused on underground plumbing without any bodies being uncovered, the inquiry remains active. It’s important to note that Eugene Horsch’s arrest was not directly linked to discoveries made at his father’s previous residence, and he has not been charged with any involvement in the women’s disappearances.
