EXCLUSIVE PHOTOS: PHILADELPHIA — Police have returned again to a home in Philadelphia's Olney neighborhood, where they collected "glass vials," a vacuum cleaner, workout equipment and other items, photographs show.
This is after city police have said they recovered more than a million pieces of digital evidence from the home, described as a "house of horrors" in some reports.
It used to belong to a pornographer named Raymond "RC" Horsch, who died last year at 82.
One evidence bag was photographed with a partially legible label. It listed "glass vials," a "board" as well as references to a bin and drawers.
Investigators were also seen taking out a rowing machine and a vacuum cleaner among boxes and bags of packaged evidence Monday.
"The investigation remains active and ongoing," a Philadelphia police spokesperson told Fox News Digital Tuesday. "Additional information will be released as it becomes available and is appropriate for public release."
Horsch specialized in sadistic themes — some of which may ultimately prove to be nonfiction after investigators say evidence in the home has been linked to seven separate cases involving missing women.
Philadelphia police have repeatedly revisited the building following the June arrest of his 44-year-old son, Eugene Horsch, on drug, firearms and forgery charges.
While searching the home after his arrest, police allegedly found "snuff" videos believed to show multiple missing women, a drum of chemicals hooked up to the water system and five urns that contained what police said might be human ashes.
Four of the seven missing women believed to be connected to the home have been identified in those images, according to authorities.
Only some of them have been publicly identified. Philadelphia police identified Maribel Fresses, 26, who vanished in 2018, and Gabrielle Aramando, 27, earlier in the investigation.
During Eugene Horsch's arrest, the woman with him had an ID for Blair Tonzelli, 38, who was last seen in Philadelphia in February 2023, police told Fox News Digital in September.
Two other women were identified in local reports. Both are listed as missing persons in the National Missing and Unidentified Person System, or NamUs.
One is Horsch's ex-wife, Amy McHale, 54, who was 44 when she was last seen on June 13, 2016, the snuff films."
"The fact that the father was involved in the pornographic industry indicates that there may have been, in addition to the sadistic motives that we usually see in serial murders, that there may have been profit in distribution of so-called snuff films," he told Fox News Digital previously.
The older Horsch was a convicted producer of methamphetamines and an author of sexually explicit and violent books. In one, 2014's "Empathy," there is a chapter about dissolving a murdered woman's body with boiling chemicals.
