On June 19, 2026, a federal park ranger encountered Eugene Albert Horsch in a BMW parked near Independence National Historical Park. A woman accompanying Horsch provided identifying information belonging to Blair Tonzelli, who had been reported missing. Investigators determined that the woman was not Tonzelli.
The encounter led authorities to examine Horsch’s connection to Tonzelli and eventually redirected attention to the West Chew Avenue property owned by Eugene, where his father, Raymond “R.C.” Horsch, had also lived. Raymond died in May 2025, more than a year before the investigation uncovered an extensive archive of digital material associated with the residence.
By September 16, 2026, investigators reported recovering more than one million digital files and examining connections to five missing women. Some recovered material appeared to depict women injured, unconscious or lifeless. Authorities emphasized that the authenticity and circumstances of the recordings still required investigation and that no remains belonging to the missing women had been recovered from the property.
The investigation began when federal Park Ranger Paul Scholtz approached Horsch’s vehicle at 8:00 a.m. on June 19, 2026. According to the federal affidavit, Scholtz heard the woman in the back seat say words indicating that she feared Horsch would hurt her. A records check subsequently established that the name she provided belonged to a missing woman.
During the encounter, rangers recovered two loaded firearms from beneath the driver’s seat, suspected narcotics, and other items. A search of the vehicle also uncovered credentials purporting to identify Horsch as a Drug Enforcement Administration agent. Federal investigators stated that Horsch had never worked for the DEA.
On June 25, 2026, Philadelphia homicide investigators, federal agents and specialized personnel searched 417 W. Chew Avenue. The investigation expanded beyond the firearms and narcotics discovered during the traffic encounter when authorities recovered computers, storage devices and other electronic evidence from the property.
The search also uncovered chemicals, containers and an unusual laboratory and plumbing configuration, prompting additional forensic examination and assistance from federal personnel.
Philadelphia Police, FBI personnel and Philadelphia Water Department crews excavated the front portion of the property and removed sections of underground piping for forensic examination. Investigators examined whether chemicals might have been used to break down biological material. No human remains were reported recovered during the excavation.
Subsequent testing determined that material initially suspected to be blood was not blood. Testing completed by July 24 had also not identified DNA belonging to Amy McHale or Blair Tonzelli inside the residence.
Raymond Charles Horsch, also known as Raymond Hoersch, was a photographer, filmmaker and writer whose work included explicit sexual imagery and violent themes. His documented history included federal convictions involving counterfeiting, controlled substances and firearms.
Raymond established an online photography presence by 1996 through his Eroto website, where he published and sold photographs and videos. Some of the women depicted in his work struggled with substance use, and his archive included material that investigators later needed to distinguish from recordings of possible actual violence.
In October 2007, 417 W. Chew Avenue was transferred to Eugene Horsch. Raymond subsequently lived at the property, which became associated with his photography and extensive collection of electronic material.
Raymond died in May 2025. His death means investigators cannot question or prosecute him concerning evidence discovered during the 2026 searches. Authorities have continued examining material attributed to Raymond to determine whether it documents crimes and whether additional missing women can be identified. Read More
By September 2026, investigators were examining connections between five missing women and the West Chew Avenue property. Their cases involve different circumstances and different levels of recovered evidence. Investigators believe digital material may show three of the women deceased, while the whereabouts of the other two remain under investigation. Read More
The digital archive recovered from the property has become one of the central components of the investigation. Early estimates included approximately 600,000 photographs, 70,000 videos and more than 10,000 pages of writings and drawings. By September 16, authorities reported that the total collection exceeded one million files.
During their September 16 briefing, Philadelphia Police Commissioner Kevin Bethel, Deputy Commissioner Frank Vanore and FBI representatives said investigators had identified 58 people appearing in recovered photographs and videos. Sixteen had been located and interviewed, 25 were known to be alive and investigators were attempting to contact them, and three people contacted by investigators declined to speak. Authorities also determined that 10 people depicted in the material had subsequently died from overdoses.
Five women appearing in the recovered material were of particular concern because the photographs or videos appeared to depict them injured, unconscious or possibly dead. Authorities had identified four of those five women but had not publicly released all their identities.
Investigators have emphasized that Raymond Horsch produced staged photographic and video material. Detectives must establish whether individual recordings depict staged scenes, actual violence or criminal conduct. An image showing someone apparently lifeless does not, by itself, establish that the person died.
Police also disclosed the recovery of five urns believed to contain cremated human remains. Investigators believed three were associated with Raymond Horsch, his sister and a friend. The identities connected to the remaining two urns had not been publicly established. No recovered remains had been confirmed as belonging to any of the missing women.
Eugene Horsch faces a separate federal prosecution arising from the June 19 encounter. A federal grand jury indicted him on charges involving possession of firearms by a convicted felon and possession of fraudulent federal law-enforcement identification documents.
Federal prosecutors alleged that he possessed two firearms despite his prior felony convictions. They also alleged that he possessed credentials purporting to have been issued by the DEA and FBI, although neither agency had issued them. Investigators recovered additional fraudulent credentials and a computer from the Chew Avenue residence.
His defense attorney, Jerome Brown, stated that the defense believed Eugene was innocent. Eugene remained in federal custody as the prosecution proceeded.
As of the September 2026 reporting covered here, Eugene Horsch had not been charged with killing, kidnapping or causing the disappearance of any of the missing women. His pending federal charges concern firearms and fraudulent credentials. Investigators have attributed some of the recovered photographic and video material to his late father, Raymond Horsch.
The investigation remains focused on authenticating the recovered recordings, identifying additional people appearing in the archive, locating the missing women and determining whether any of the material documents criminal acts. Authorities must also establish the circumstances surrounding any suspected deaths without recovered remains.
As investigators continue reviewing the extensive archive, the identities and experiences of the women remain central to the case. Some have families who have searched for answers for years, and the recovery of photographs and videos has raised further questions about when they were last alive and what occurred inside the property.
