Philadelphia police found a “significant amount” of blood inside the decrepit Olney house linked to the investigation of at least two missing women, multiple law enforcement sources said.
The sources, who spoke on the condition of anonymity to discuss an ongoing investigation, said forensic testing has not yet determined whose blood it is or whether it’s even human — a process that could take several weeks to complete. But, the sources said, police are prepared to excavate the front and backyards of the Chew Avenue home in the coming weeks in search of potential human remains.
Deputy Police Commissioner Frank Vanore declined to confirm or comment on the discovery Monday afternoon, citing the ongoing investigation. Vanore said Friday that police had not recovered any human remains from the home and were awaiting testing of the tubs of chemicals and other materials found in the basement.
The finding marks the latest development in an unusual saga that began after the arrest of Eugene Albert Horsch, 44, the owner of the Olney home now being searched by law enforcement for a second week in connection with the disappearance of at least two women who have been missing for years.
Horsch was arrested June 19 after U.S. Park Police saw him parked in his black BMW near 6th and Market Streets, acting suspicious. When a ranger approached the car, police said, he heard a woman in the back seat say, “You’re going to hurt me” and saw drug paraphernalia. Police searched the car and recovered two guns with obliterated serial numbers, as well as cocaine, fentanyl, and marijuana, a cattle prod, switchblade knives, handcuffs, and a fake U.S. Drug Enforcement badge featuring Horsch’s photo.
The woman with Horsch falsely identified herself to the officers using the name of a 38-year-old woman who had been reported missing in Kensington in February 2023, police said.
The woman, 39, later told investigators she’d given the alias because she had open warrants for her arrest in ongoing drug cases, and that Horsch had made her fake identification cards in that name and said she could use it if she was ever stopped and questioned by police, sources said.
The woman said she did not know the woman whose name she was using or even that she was missing — but the way Horsch spoke about her and other women made her feel like something bad had happened to her, the sources said.
Philadelphia homicide detectives then began reviewing that missing woman’s case, and, alongside federal law enforcement, searched Horsch’s home at 417 W. Chew Ave. last week.

That search produced a trove of bizarre discoveries: a basement with drums filled with chemicals, bottles of unknown substances, the death certificate of another woman, and what appeared to be urns holding at least one of Horsch’s relatives’ cremated remains. Investigators also found another handgun, materials used to grow marijuana, and a 55-gallon drum with connections to waterlines leading into a hole in the ground.
Federal investigators also discovered a multipage, unsigned, handwritten letter that appeared to describe hurting people and referenced the serial killer Ted Bundy, according to the affidavit of probable cause to search the home that was obtained by The Inquirer.
Law enforcement sources said police were working to determine whether the writings were part of a novel or screenplay. Horsch’s late father, Raymond “R.C.” Horsch was a known drug manufacturer and erotic filmmaker who had published several works of fiction with violent, masochistic themes, including one described as an “autobiographical memoir of a caring, empathetic serial killer.”
The probe into the younger Horsch took another twist when investigators learned that Raymond Horsch’s ex-wife, Amy McHale, was last seen at the Olney property in 2016 and has never been found. A lawyer for Eugene Horsch and his father said the two men had nothing to do with McHale’s disappearance and said she struggled with substance abuse and mental illness.
Horsch has been charged with illegal gun possession and drug crimes by Philadelphia authorities.
He is also facing a federal gun possession charge, court records show. The U.S. Attorney’s Office filed a complaint against Horsch on Friday, charging him with possession of a firearm by a felon and centering their allegations on the guns that park rangers found in his car during an encounter in Center City earlier this month.
Horsch has not yet been arraigned in that matter, and he remained in a city jail, held on $500,000 bail as of Monday afternoon. But the case could give federal prosecutors an opportunity to argue to a judge that he remain in federal custody until trial.
