Local and federal law enforcement officers have returned to a home in a Philadelphia neighborhood tied to at least seven missing women.
Five of those women are presumed dead, though no human remains have been found.
The home was once owned by Raymond “R.C.” Horsch.
The known erotic photographer and snuff-film maker died in 2025.
On Monday morning, Philadelphia police alongside the FBI were seen at the home preparing to dig for clues.
Sources told our NBC affiliate there that they could be bringing in heavy machinery to the property so teams can take down walls and remove floorboards as they search for evidence.
The work could last as long as two weeks.
The investigation kicked off back in June after the son of R.C. Horsch, Eugene, was arrested.
Eugene’s trial on unrelated felony charges has been postponed until at least March.
Eugene faces no charges connected to the missing women.
