Philadelphia investigators say the house of horrors on West Chew Avenue just got worse: five missing women are now believed linked to a father-son duo who lived at the modest Olney rowhome, with detectives combing through more than one million photos and videos pulled from the property in search of proof.

The case cracked open in June, when National Park Police stopped 44-year-old Eugene Horsch during a traffic check near 6th and Market streets. A woman in the passenger seat was carrying a fake ID bearing the name of Blair Tonzelli, a woman who vanished in 2023. Officers found illegal handguns, a phony DEA badge and a stash of drugs, and Horsch has since been indicted on federal weapons and false-credential charges, according to ABC News.

What followed was a search of the 400 block of West Chew Avenue that investigators describe as one of the most disturbing in recent city history. Police recovered five urns believed to hold cremated remains, a 55-gallon drum rigged to water lines, hidden compartments stocked with chemicals, a small marijuana grow operation and roughly 120 pieces of ballistic evidence, per 6abc Philadelphia. A handwritten note referencing serial killer Ted Bundy and body-disposal methods was also found inside.

"Believed Deceased"

Investigators have named five women they believe are connected to the property: Nicole Fusaro and Maribel Fresses, both 27 when they vanished in 2018; Gabrielle Amarando, 22 when she disappeared in 2012; Blair Tonzelli, 35, missing since 2023; and Amy McHale, 44, last seen in 2016 and once married to Raymond Horsch, Eugene's late father, who died in 2025 at age 82. Video evidence reportedly shows Raymond Horsch placing a zip tie around one woman's neck, and images pulled from the home appear to show at least two of the women deceased, according to CBS News Philadelphia.

No bodies have been recovered despite months of digging and searching, and police caution that without remains, they cannot issue death certificates. "We have a duty to those families that are concerned about whether their loved one lost their lives in that house, or maybe somewhere else," Philadelphia Police Commissioner Kevin Bethel said at a briefing this week, according to NBC10 Philadelphia.

"There is thousands and thousands of videos that need to be gone through. We need to corroborate what we see."

That warning came from Deputy Police Commissioner Frank Vanore, who said investigators have worked through only about 30% of the more than one million digital files pulled from the property so far. The FBI has added dozens of agents to help authenticate the material, and a forensic lab in Chicago is testing more than 20 containers of unidentified substances found inside the home.

For now, Eugene Horsch remains in federal custody solely on the weapons and fake-credentials charges stemming from his June arrest, not on any charge tied to the missing women, since no bodies or definitive proof of death have surfaced. Philadelphia police have signaled a further update could come within days as the digital evidence review continues, and grieving families are being kept in the loop as investigators race to determine whether that Olney rowhome claimed even more victims than currently known.
