Philadelphia police and the FBI are investigating an Olney home linked to at least five missing women as authorities review more than 1 million digital files recovered from the property.
Philadelphia police say they've identified dozens of people seen in videos they recovered from the Olney house at the center of a massive investigation.

The sprawling investigation centers on a house in the 400 block of West Chew Avenue associated with 44-year-old Eugene Horsch and his late father, Raymond “R.C.” Horsch. Investigators say photographs and videos recovered from the home show dozens of people, including women who appear injured, unconscious or possibly dead.
But police have stressed that no body linked to an alleged victim has been recovered from the property, and investigators are still working to establish what the footage actually shows.
Five missing women are linked to the Olney investigation
The women publicly connected to the inquiry are Gabrielle Amarando, Maribel Fresses, Nicole Fusaro, Amy McHale and Blair Tonzelli.
Amarando disappeared in 2012 and police say she appears in images dated years later. Fresses has also been identified in recovered material. Nicole Fusaro, missing since 2018, became the fifth woman publicly linked to the investigation in September.
McHale disappeared in 2016. Her family says she left her daughter a voicemail saying she was at the Chew Avenue house with R.C. Horsch, her former husband.
Tonzelli has been missing since 2023. Her identification allegedly surfaced during Eugene Horsch’s June arrest, helping lead investigators toward the Olney property.
June arrest opened the door to a much larger case
Eugene Horsch was arrested June 18 after a park ranger approached his vehicle near Independence Mall.
Authorities allege a woman accompanying him possessed identification belonging to Tonzelli. Investigators also allegedly recovered two guns, a switchblade, drug paraphernalia and fraudulent identification portraying Horsch as a federal agent.
Horsch later faced federal firearms and impersonation-related charges. Those charges are separate from the missing-women investigation, and police have not charged him with killing the five women.
Only about 30% of the digital evidence has been reviewed
The search of the Olney property produced computers, hard drives, phones, cameras and an enormous archive of digital material.
Investigators say more than 1 million files are now being examined. The FBI said only about 30% had been reviewed by the September 16 update.
Police have identified about 58 people in the material so far. Sixteen have been interviewed, while another 25 known to be alive are being contacted. Ten other people seen in the files are known to have later died from overdoses elsewhere in Philadelphia.
Five women shown in recovered footage are causing particular concern because they appear injured, unconscious or lifeless. Investigators believe they know the identities of four of them.

Disturbing 2017 video is under investigation
One video described by police is dated 2017 and shows R.C. Horsch with a woman inside the house.
Investigators say she is seen using drugs and receiving money before being handcuffed to a bed. Police say a zip tie is then placed around her neck and she appears to lose consciousness.
Deputy Commissioner Frank Vanore cautioned that the woman’s fate has not been confirmed because no body has been recovered.
Police have also said some recovered footage may involve staged or role-playing activity, making independent evidence and interviews essential before investigators can determine what actually occurred.
Five urns, chemicals and ballistic evidence were found
Searches of the property also uncovered five urns believed to contain human ashes, potentially dangerous chemicals, a 55-gallon drum connected to hoses or piping, drugs and a small marijuana-growing operation.
Authorities also recovered nearly 120 pieces of ballistic evidence and later excavated pipes outside the property.
Police believe one urn contains R.C. Horsch’s remains, another contains his sister’s ashes and a third belongs to a friend. The identities associated with the other two remain under investigation.
Authorities have not said any of the urns contain one of the missing women.
FBI review could still expand the case
The investigation remains far from complete because roughly 70% of the digital archive had yet to be reviewed at the latest briefing.
Investigators are continuing to identify people shown in the files, conduct interviews and determine whether additional searches are necessary.
Anyone with information can contact the Philadelphia Police Department.
The case comes as families elsewhere continue to wait for answers in prolonged missing-person investigations, including the Noah Woods disappearance and Suffolk investigation.
Another recent criminal investigation involved the Westchester Community College stabbing, where authorities similarly relied on witness interviews and developing evidence to establish the sequence of events.
For the families of Amarando, Fresses, Fusaro, McHale and Tonzelli, the central question remains unresolved: whether the growing evidence archive can establish what happened to each woman and whether additional people will ultimately be connected to the Olney property.
