Philadelphia police have linked at least four missing persons cases to a residential property in the city’s Olney neighborhood after seizing roughly 600,000 images, 70,000 videos, and 10,000 pages of text from 44-year-old Eugene Horsch, according to local authorities and media reports. Investigators recovered digital files depicting two missing women as deceased, while the property yielded urns with suspected human remains and a basement setup featuring chemical containers.
Philadelphia Police Seize Hundreds of Thousands of Digital Files in Olney Home Investigation
According to People and NBC reports, law enforcement officials executed a search warrant at the Chew Avenue home formerly owned by Eugene Horsch’s father, Raymond “R.C.” Horsch, who died in 2025. Inspector Ray Evers described the seized material as “graphic and dark” during a press conference covered by People. The haul includes approximately 600,000 photos, 70,000 videos, and 10,000 pages of manuscripts and drawings. Horsch is currently being held in custody, though he has not been formally charged in connection with the missing women. His defense attorney, Jerry Brown, told CNN that his client plans to plead not guilty and dismissed the police search as being “on a wild-goose chase.”
Photographic Evidence Connects Missing Women to the Olney Property
Among the digital images recovered from the home, investigators identified two missing women who appear to be dead, though their bodies have not been located, according to police statements cited by People. The women are Maribel Fresses, who was last seen in February 2018 (with federal databases noting her family last saw her in June or July 2018 at her boyfriend’s home in Philadelphia’s Kensington area), and Gabrielle Amarando, who vanished in September 2012. A medical examiner stated that if the recovered images are authentic and unedited, they indicate the women are deceased. A fourth missing person, Amy McHale, who was married to Horsch’s father and disappeared in 2016 after visiting him, is also linked to the case by investigators.
Traffic Stop Led Authorities to Horsch and Missing Persons Evidence
The investigation began on June 19 when a park guard at Independence National Historic Park intervened in a dispute between Eugene Horsch and a woman inside a vehicle, according to CNN. A passenger in the back seat called out that Horsch was going to harm her. Police searched the car and recovered false Drug Enforcement Administration identifications, a springknife, two un-serialized firearms, narcotics, and a cattle prod. The woman inside the vehicle possessed an identification card bearing the name Blair Tonzelli, a 35-year-old woman who has been missing since 2023. Inspector Evers told People that investigators fear they may never see Tonzelli again.
Basement Lab and Urns Discovered During Chew Avenue Search
During the search of the Olney residence, investigators found five urns containing suspected human remains, a makeshift laboratory in the basement, and containers filled with an unknown oily liquid, according to CBS News. Detectives have been examining the property for traces of alkaline hydrolysis, a chemical process sometimes referred to as wet cremation used to break down human tissue. The elder Horsch, Raymond “R.C.” Horsch, operated as a filmmaker and erotic photographer who produced graphic underground films featuring sadomasochistic themes involving women.
