Philadelphia police and the FBI are zeroing in on a woman identified only as “A.T.” after she was seen with Eugene Horsch during his June traffic stop in the 600 block of Market Street. Court documents obtained by Action News confirm the woman’s initials and note that she has lived in a Northeast Philadelphia neighborhood for years, with neighbors describing her as a longtime resident who has spent time in and out of jail.
Neighbors describe A.T. and her connection to Horsch
One neighbor recalled seeing Horsch waiting for the woman, saying, “He was infatuated with her. He’d wait for hours for her; she made him wait.” The same neighbor later said Horsch would often come to the area to pick her up, but stopped after his June arrest. “I told her she wasn’t welcome anymore and she left,” the neighbor said, adding, “I didn’t like she was bringing people like that around my house.”
Police encounter and evidence found
According to authorities, a federal park ranger spotted a black BMW parked on Market Street and approached the vehicle. Inside, a female voice reportedly said, “You’re going to hurt me.” The ranger’s report led to the discovery that the driver was Eugene Horsch, who was arrested on federal gun charges. During the stop, investigators recovered an identification card bearing the name Blair Tonzelli, a woman reported missing, prompting a broader search of the Horsch family home on Chew Avenue.
Later, agents executed a search warrant at a residence linked to A.T. in November 2024. The search yielded conspiracy and drug‑related charges filed against her the following day, though she has not been charged in the Horsch case itself. Video released by Action News shows agents serving the early‑morning warrant.
Forensic work expands the investigation
Police and FBI investigators have used luminol at the Chew Avenue property, a chemical that can reveal hidden blood traces. Sources told Action News that a positive reaction was observed, though further laboratory analysis is pending. Teams also uncovered a hidden safe behind a wall while dismantling portions of the house.
Investigators have been digging in the backyard, recovering bones that will be tested to determine whether they are human or animal. The Chew Avenue home is already linked to at least seven missing or unidentified women, raising concerns that the property could hold additional evidence.
Next steps
Eugene Horsch is scheduled to appear in court again in March. Authorities say the presence of A.T. during the June traffic stop is considered significant, and they continue to interview neighbors and review surveillance footage to piece together her relationship to the broader missing‑women investigation.
While A.T. has not faced charges related to the Horsch case, the ongoing forensic work and the discovery of the missing‑person ID suggest that her involvement may provide crucial leads for investigators seeking answers for the families of the missing women.
