PHILADELPHIA, PA — Philadelphia investigators say a sprawling case tied to a West Olney house has now linked seven missing women to the property and to brothers Eugene and Raymond “R.C.” Horsch. Police have spent months examining the home, its contents and thousands of digital files while trying to determine what happened to the women who disappeared over more than a decade.
Detectives have urged anyone who spent time inside 417 West Chew Avenue, or who knows anything about activity there, to contact police. They have also asked families who fear a missing loved one may be connected to the residence to come forward as federal and local investigators keep building the timeline.
Early convictions and disappearances stretch back years
The history investigators are now examining reaches back long before the federal search warrants and video evidence of 2026. Court records show Eugene Horsch was convicted in January 2004 of aggravated assault and aggravated battery by vehicle and received a sentence of two to four years.
That same long arc includes multiple missing-person cases in Philadelphia. Gabrielle Amarando, 22, disappeared in 2012. Maribel Fresses, 28, vanished in 2018, while Blair Tonzelli, 35, was reported missing in 2023. Nicole Fusaro, 27, was also reported missing in 2018. Police say the case has become one of the most complex they have handled in recent memory.
Amy McHale’s disappearance put the Chew Avenue house on police radar
One of the earliest and most important links to the Olney house came in June 2016, when Amy McHale, 44, was last seen there. McHale had been married to R.C. Horsch, and her daughter, Amanda Stofer, said McHale left a voicemail the day she disappeared saying she was at the home and was safe.
Stofer said R.C. Horsch told her and her grandmother, and later detectives, that McHale had been at the house and was gone by morning. Family members have said the developments in 2026 pulled their attention back to the same residence, where McHale was last known to be alive.
Investigators have not said publicly what they believe happened to McHale, and her body has not been found. Her case remains one of the central reasons the Chew Avenue property drew intense scrutiny when detectives began searching it again.
A June arrest on Independence Mall added guns, drugs and fake credentials
The investigation accelerated sharply on June 19, 2026, when a federal park ranger noticed a black BMW parked where it should not have been on the 600 block of Market Street near Independence Mall. According to police, the ranger approached the occupants and thought he heard a woman say, “you’re going to hurt me.”
Officials said Eugene Horsch then allegedly showed fake DEA and FBI credentials when asked for identification. Investigators also said the ranger noticed sores on the driver’s arms and face, and a woman in the car appeared agitated and had sores of her own. Police later said two loaded guns, a knife, a cattle prod, a collapsible baton, handcuffs and crack cocaine were recovered from the vehicle.
One of the guns had an obliterated serial number, and the woman allegedly carried identification with Tonzelli’s name and her own photo. She said Horsch gave her the ID, according to investigators.
Chemicals, pipes and handwritten notes turned the house into a major evidence scene
By June 26, police were publicly describing a very unusual scene inside the West Chew Avenue property. Detectives said chemicals, ammunition and drugs had been found, including basement items tied to a 55-gallon drum and water-line connections. Deputy Commissioner Frank Vanore called it a “strange setup.”
Authorities said the volume of chemicals raised concerns because some could create hazards if mixed and ignited. Police also addressed rumors of bodies in the house, saying none had been found at that point. Eugene Horsch’s attorney, Jerry Brown, said the chemicals belonged to Horsch’s father and were not dangerous.
Later, documents obtained by Action News showed zip ties and a handwritten note mentioning serial killer Ted Bundy and ways to dispose of trash. Authorities said the note had no signature. Federal custody followed as the scene stayed secured.
Forensic teams widened the search as the digital cache grew to millions of files
As the case moved into July and August, investigators kept digging literally and digitally. Cadaver dogs were brought to the property, the perimeter was expanded and FBI agents were seen moving in and out of the home. Crews later excavated pipes from the front yard and street to examine them for possible evidence.
Police also said they recovered about 600,000 images and 70,000 videos from hard drives found at the residence. By mid-August, investigators were reviewing more than one million images overall, according to sources. Police said the files included images from inside the home that appeared to show two women dead.
Inspector Ray Evers said that if the images were authentic and unaltered, the medical examiner would believe the people shown were deceased. Investigators identified those women as Gabrielle Amarando and Maribel Fresses, though neither body has been found.
Video, federal charges and renewed searches keep the case active
On Sept. 10, police said they had seen video that allegedly shows R.C. Horsch strangling a woman. Days later, investigators identified Nicole Fusaro as a fifth missing woman connected to the Olney home, and family members said they had been meeting with detectives about the case.
Police said on Sept. 16 that five women appearing injured, lifeless or possibly dead were seen in the digital evidence recovered from the house, bringing the total number of missing women tied to the investigation to seven. Officials also said about 60 people appear in the videos, and some have already spoken with investigators while others have not.
Vanore said some of the footage appears to be playacting while other material may be real, and he stressed that investigators are still working to authenticate what they found. Police said they expect to return to the house again with another search warrant in late September as the federal case continues.
