“I’m not gonna get into exactly what I saw. It’s dark. It’s real dark.”
Philadelphia has no shortage of dark chapters in its history, but an ongoing investigation surrounding a home in the city’s Olney neighborhood is now raising some deeply disturbing questions about what may have happened inside. We’re talking straight S7VEN-style horrors ahead, so be warned.
The investigation began in June after 44 year old Eugene Albert Horsch was arrested following a traffic stop near Independence Mall. Police found firearms, drugs and fraudulent federal identification connected to Horsch. A woman who was with him was also carrying identification belonging to Blair Tonzelli, a Philadelphia woman who has been missing since 2023. That discovery eventually brought investigators to Horsch’s home on West Chew Avenue.
What police discovered inside the property has since transformed the case into something much larger.
Investigators have executed more than 95 search warrants while combing through the house and its contents. They have recovered approximately 600,000 images, 70,000 videos and 10,000 pages of writings, manuscripts and drawings, along with five urns believed to contain cremated remains and more than 20 containers holding unidentified chemicals and oily substances. Authorities also recovered firearms, ammunition, electronic storage devices and other materials that investigators are still examining.
That’s a whole lotta bad in one place, but that’s not even half of it.
TWO MISSING WOMEN APPEAR TO BE DEAD
Police say detectives reviewing one of the hard drives discovered photographs and videos showing two women who had previously been reported missing. They were identified as Maribel Fresses, who was reported missing in February 2018, and Gabrielle Amarando, who disappeared in September 2012. Both women were born in 1990. Investigators say some of the footage shows the women alive and later appears to show them deceased. Their bodies have not been found. All those barrels with chemicals could be a means for liquid cremation ala Jefferey Dahmer status. Which makes the killings/ disappearances even more disturbing.
Philadelphia Police Inspector Raymond Evers stressed that investigators are dealing with an enormous amount of material and that only roughly 5% to 7% of the digital evidence had been reviewed when authorities announced the discovery. Police have described the material as “graphic and dark” and are continuing to determine what is authentic and what it may mean.
That distinction matters.
Horsch has not been charged with the deaths or disappearances of Fresses or Amarando, and authorities have not publicly identified him as a suspect in those cases. Police are still working to establish what happened and who may have been responsible.
THE OTHER MISSING WOMEN
Fresses and Amarando aren’t the only missing women whose names have surfaced during the investigation.
Blair Tonzelli disappeared in 2023, and her identification was allegedly being carried by the woman who was with Horsch when he was stopped in June. Investigators have also been looking at the disappearance of Amy McHale, who was previously married to Horsch’s father, Raymond “R.C.” Horsch, and was last seen at the West Chew Avenue property in 2016. The connection to Raymond Horsch has added another disturbing layer to the investigation.
R.C. Horsch, who died in 2025, was involved in erotic filmmaking, photography and writing, with some of his work focusing heavily on violent and sadomasochistic themes. Investigators are now examining material from the property that dates back through the years the father and son lived there.
An unsigned handwritten document found inside the home reportedly contained references to harming people and mentioned serial killer Ted Bundy, along with references to zip ties and a drum. Investigators have not established who wrote the material. Horsch’s attorney has previously suggested that some of the writings could have originated with his late father.
PHILADELPHIA KNOWS WHAT A HOUSE OF HORRORS CAN LOOK LIKE
The attention surrounding the West Chew Avenue property has inevitably brought up two of Philadelphia’s most infamous killers.
In 1986 and 1987, Gary Heidnik kidnapped six women and held them captive in a basement pit at his North Philadelphia home. Two of those women were murdered. Heidnik was convicted of murder and other charges and was executed in 1999. His crimes later became one of the real life influences behind Buffalo Bill in The Silence of the Lambs.
Around the same period, Harrison “Marty” Graham murdered seven women in Philadelphia between 1986 and 1987. Their remains were discovered inside his apartment, earning the property the grim nickname “Death House.” Graham was convicted of seven murders and ultimately received a life sentence after his death sentences were overturned.
Those cases are part of Philadelphia’s history, but it is important not to blur that history with what investigators currently know about the Horsch case.
Right now, there is no serial murder charge against Eugene Horsch. There isn’t even a body.
What investigators do have is an extraordinary amount of digital and physical evidence, several missing women connected in different ways to the same property and footage that Philadelphia police believe appears to show two missing women after their deaths.
And investigators have barely scratched the surface of what is inside those files.
As the search continues, authorities are still trying to answer the questions that matter most: What happened to these women? Who created the material found inside the house? How much of the evidence is connected to actual crimes, and how much may be disturbing fiction or artwork?
Until investigators finish working through that mountain of evidence, the West Chew Avenue house remains exactly what it has become in this investigation: a place filled with questions, and very few answers.
