Human DNA Found Inside Philadelphia “House of Horrors” as Investigators Search for Answers in Cases of Seven Missing Women

A disturbing discovery inside a Philadelphia home has intensified an already chilling investigation involving seven missing women. Authorities have confirmed that human DNA was found at the property, known as the “House of Horrors,” where investigators have spent months searching for evidence that could explain the women’s disappearances. The discovery has raised fresh hopes that forensic testing may help detectives uncover what happened inside the house, although officials have yet to find human remains or file homicide charges connected to the missing women.

The property, located on West Chew Avenue in Philadelphia’s Olney neighborhood, was previously owned by Raymond “R.C.” Horsch, a filmmaker and photographer who died in 2025. His son, Eugene Horsch, 44, now owns the house and was arrested in June 2026 on separate drug and weapons charges. What initially began as an investigation following Eugene’s arrest has since expanded into a complex case involving a massive collection of digital evidence, suspicious equipment and several women who have reportedly vanished after being connected to the residence.

Investigators reportedly discovered more than one million photographs and videos stored inside the property. Authorities have identified 58 individuals in the recovered material, and some of the images appear to show women who were later reported missing. Police believe five of the seven missing women linked to the home may be dead, although their deaths have not been officially confirmed because investigators have not recovered their bodies. The women connected to the investigation include Blair Tonzelli, Amy McHale, Maribel Fresses, Gabrielle Amarando and Nicole Fusaro. Detectives are continuing to examine the digital files in an effort to establish what happened to them.

The latest breakthrough came after investigators used luminol, a chemical that can help reveal traces of blood that are not visible to the naked eye. Police sources told CBS Philadelphia that human DNA was discovered in several areas of the home following the testing. The samples are now expected to undergo further forensic analysis. Investigators hope the results may help determine whose DNA was found and whether it can be connected to any of the missing women. However, the discovery alone does not establish that a homicide occurred at the property or identify anyone responsible for a crime.

The search has uncovered other troubling evidence, including firearms-related materials, fake federal identification documents, chemical containers, urns and a large drum connected to pipes in the basement. Investigators have also removed sections of sewer piping for laboratory examination and are continuing to inspect areas of the building that may contain additional evidence. Authorities have not publicly confirmed that the equipment or materials were used in a killing, but their discovery has prompted a much deeper examination of the property.

The case first attracted widespread attention after Eugene Horsch was stopped near Independence National Historical Park in June. During that encounter, authorities allegedly discovered firearms, drugs and identification documents connected to the investigation. A woman who was with him reportedly possessed identification belonging to Blair Tonzelli, who had been missing since 2023. That discovery helped investigators establish a potential link between the property and the missing-women cases. Eugene remains in federal custody on charges stemming from the June incident, but he has not been charged with any homicide connected to the missing women. His attorney has previously disputed aspects of the allegations surrounding the property.

As investigators continue testing the DNA and examining the enormous collection of digital evidence, families of the missing women are still waiting for answers. Detectives must determine whether the material recovered from the house can establish what happened to the women and whether any criminal acts took place inside the property. For now, the DNA discovery represents a significant development in a case filled with disturbing unanswered questions. Authorities are urging anyone with information about the residence or the missing women to come forward as the search for the truth continues.
