Overview
- Eugene Albert Horsch was arrested following a June 19 encounter in Center City that led officers to search his Olney rowhouse and seize weapons, drugs and a fake DEA badge.
- Searches of 417 W. Chew Ave uncovered large quantities of unknown chemicals, a 55‑gallon drum rigged to water lines, urns, multiple firearms and an unsigned multi‑page note referencing violence and Ted Bundy.
- Police reported a significant amount of blood inside the house but said forensic tests have not yet determined whether it is human or whose it is.
- The FBI, Hazmat teams and Philadelphia forensic units have collected materials for laboratory analysis, have begun sewer inspections, and say they may excavate yards as testing continues.
- Horsch was arraigned on a federal charge of being a felon in possession of a firearm and ordered detained while investigators probe possible links between items found in the home and at least two women who disappeared in 2016 and 2023.
