In brief
In June 2026, a U.S. Park Police ranger stopped a BMW near Independence Mall in Philadelphia. The driver, Eugene Horsch, 44, had two loaded handguns and fake federal credentials, and his passenger carried an ID with her own photo and the name of a woman missing since 2023. The stop led investigators to 417 West Chew Avenue in the Olney neighborhood, the house Eugene had inherited from his father, Raymond "R.C." Horsch, an erotic photographer and filmmaker who died there in May 2025. Inside they found chemicals, a 55-gallon drum plumbed into the water lines, five urns of ashes, and more than a million digital files. By September, police had identified 58 people in the images, said several women who appear unconscious or injured in them are missing, and described a 2017 recording in which a woman appears to be strangled. No remains of any missing woman had been found, R.C. Horsch was never charged with harming anyone, and Eugene Horsch has not been charged in connection with any of the women.
Turning pointA deputy commissioner described a 2017 recording, made by two cameras in a bedroom, in which a woman is zip-tied around the neck until she goes limp. Then he added that she only appeared lifeless, and that police could not yet tell staged from real.

Timeline
1973
R.C. Horsch makes his first film. Over the next five decades he photographs women and makes erotic films, alongside convictions for counterfeiting, drug manufacturing and identity theft.
2006
Horsch transfers the Chew Avenue house to his son Eugene. The same year he films Snuff with a friend in a single afternoon, later saying he played the killer and was a natural at it.
2013
Cassandra Barone begins posing for Horsch for money and a place to stay. She later tells NBC10 he cooked for her and washed her clothes, the house smelled, and he told her not to go into the basement.
May 2025
R.C. Horsch dies inside the house, aged 82. A fire there the same month leads to a narcotics search.
June 19, 2026About 8 p.m.
A U.S. Park Police ranger stops Eugene Horsch's BMW on Market Street. Inside are two loaded handguns and credentials falsely identifying him as a federal agent. His passenger's ID bears her photo and the name Blair Tonzelli, a woman missing since 2023.
Late June 2026
Investigators search 417 West Chew Avenue and find weapons, chemicals, a makeshift lab, a 55-gallon drum connected to the water lines, five urns of cremated remains, and dozens of cameras, phones and hard drives.
July 2026
A federal grand jury indicts Eugene Horsch on firearm and false-identification charges. Crews remove a section of sewer pipe from the property. No remains of the missing women are found.
September 16, 2026
Police and the FBI say they have identified 58 people in the files, about 30 percent of which have been reviewed. Deputy Commissioner Frank Vanore describes a 2017 two-camera bedroom recording and says some footage is play-acting and some could be real.
September 2026
The FBI says it plans to return to the house with new warrants, guided by what investigators have seen in the footage.
The full story
A traffic stop
On the evening of June 19, 2026, a U.S. Park Police ranger walked up to a black BMW parked on Market Street near Independence Mall in Philadelphia. The driver was Eugene Horsch, 44. In the car were two loaded handguns, drugs, and credentials claiming he was a federal agent. His passenger handed over an ID with her own photograph on it and someone else’s name: Blair Tonzelli, a woman reported missing in 2023.
The stop led police to a boarded-up, fire-damaged rowhouse at 417 West Chew Avenue in Olney. Eugene had owned it since 2006. Before that it belonged to his father.
The man behind the camera
Raymond “R.C.” Horsch had spent fifty years photographing women and making erotic films, between prison terms for counterfeiting, drug manufacturing and stealing a chemist’s identity. Many of the women he photographed in later years were struggling with addiction in Kensington. He paid them, and some stayed at the house. One of them, Cassandra Barone, told NBC10 he cooked for her and washed her clothes. The only things that bothered her, she said, were the smell and being told never to go into the basement.
His work circled death. A gallery on his website called “Thanatopsis” warned that some images showed women acting out their own deaths, and claimed that others showed real overdose victims. He wrote a book narrated by a serial killer and made a film called Deleted Scenes: A Serial Killer’s Video Journal. In an archival interview he said that playing the killer in a staged film had come naturally to him. He died in the house in May 2025.
What police found
In the basement were chemicals, a makeshift lab and a 55-gallon drum plumbed into the water lines. Elsewhere were five urns of ashes, one of which police believe holds Horsch’s own remains. Crews dug up sewer pipes outside and found no remains of any missing woman. What they did find was an archive: more than 600,000 images, about 70,000 videos, and thousands of pages of writing and drawings.
By September 16, police had identified 58 people in that material. Some were alive. Ten had later died of overdoses elsewhere in the city. Several women who appeared unconscious or injured in images taken in the house, including Gabrielle Amarando and Maribel Fresses, were missing. Deputy Commissioner Frank Vanore described one recording dated 2017, filmed by two cameras in a bedroom, in which Horsch handcuffs a woman to a bed and tightens a zip tie around her neck until she goes still. She appeared lifeless, he said, but that was only how it appeared.
Staged or real
“Some of this is play-acting,” Vanore said. “Some of it we believe could be real, but we’re not there yet.” Investigators had worked through about 30 percent of the archive. The FBI planned to return to the house.
R.C. Horsch was never charged with harming anyone. His son faces federal firearm and false-identification charges only, and police say they have found nothing tying him to the missing women. The question the archive holds, which recordings were staged and which were not, has no answer yet.
What the video couldn't include
The woman with someone else's name
The passenger in the BMW was not Blair Tonzelli. Police say she told them Eugene Horsch gave her the ID. Vanore said there was no evidence Tonzelli had ever been inside the house. She is still missing.
Who is in the files
Of the 58 people identified by mid-September, police said some were alive and ten had later died of overdoses at other places in Philadelphia, not at the house. Among the women police connect to the material are Gabrielle Amarando, missing since 2012, and Maribel Fresses, missing since 2018.
A name for the woman in the 2017 video
In late August, the Philadelphia Inquirer reported that police believe one recording shows R.C. Horsch killing a woman. Relatives and law-enforcement sources later identified her as Nicole Fusaro, 27, missing from Kensington since July 2018. No body has been recovered and no medical examiner's finding has been made.
The ex-wife
Amy McHale, who was married to R.C. Horsch from 2004 to 2008, was last seen at the Chew Avenue house in June 2016. Her daughter has said she believes her mother is dead.
Thanatopsis
Horsch's website gallery "Thanatopsis (Musings on death)" warned that some images showed collaborators imagining and acting their own deaths, and claimed others showed real overdose victims. That claim is his own; police have not confirmed it.
Earlier warnings
In 2009, police in New Britain Township, Bucks County, arrested Horsch at his Chalfont home on marijuana and firearms charges and found the IDs of several women there. The former police chief says he does not know what happened with that evidence afterward.
Eugene Horsch's case
Eugene Horsch is in federal custody on firearm and false-identification charges. Five state charges were withdrawn in August. Police said on September 16 that they had found no evidence connecting him to the dead or missing women. He is presumed innocent.
