On October 15, 2026, investigators found bones buried about three feet deep in the backyard of 417 West Chew Avenue in Philadelphia's Olney section, the property of Raymond R.C. Horsch, who died in 2025. The search has since turned up a makeshift crematorium and blue barrels of alkaline solution, a safe containing documents hidden behind a wall, and a letter referencing serial killer Ted Bundy. More than 95 search warrants have been executed in connection with the house. Whether the bones are human and tied to the missing women remains unconfirmed.
