Philadelphia serial killer probe brings in reinforcements to dig through home tied to missing women: report

Investigators have returned to the infamous Philadelphia home of the late Raymond "R.C." Horsch to search the property yet again for any clues in a case involving multiple missing women and a potential serial killer.

Philadelphia police and federal investigators were seen at the home on Monday as they executed a search warrant, FOX 29 Philadelphia reported.

Authorities are ramping up their search of Horsch's home on Chew Avenue in Olney – an effort they said will shut down roads and involve more digging at the property, according to the outlet.

Authorities are working to determine what the disturbing images and videos depict, particularly because Horsch was known for producing violent pornography.

Horsch, an 82-year-old who produced brutally themed pornography and books, died last year.

His son Eugene Horsch, 44, was arrested in June on charges involving unlawful firearms and forgery, which led police to make concerning discoveries at the family home.
