More than 1 million digital images, disturbing videos and hidden spaces containing chemicals and other evidence have been uncovered at a Philadelphia home linked to five women who have been missing for years, as police investigate what happened to them.
Investigators searching the Olney property have identified 58 people in the recovered images and videos.
Police said five people appear lifeless or unconscious in some of the material, while investigators believe five missing women connected to the house are dead. However, no bodies have been recovered, and no human remains from any of the women have been confirmed.
The investigation centres on a home owned by Eugene Horsch, 44, whose late father, R.C. Horsch, also lived there before his death last year. Eugene was arrested in June and is facing firearms, drug and other charges unrelated to any confirmed homicide.
How the Philadelphia Home Caught Police's Attention
The investigation began to draw wider attention after Eugene Horsch was arrested in June following an encounter near Philadelphia's Independence National Historical Park.
According to a criminal complaint, a park ranger approached Horsch after seeing him illegally parked. A woman was inside the vehicle, and authorities said her identification documents belonged to Blair Tonzelli, one of the women reported missing since 2023.
A search of Horsch and the vehicle allegedly uncovered a switchblade, two guns, drug paraphernalia and forged documents identifying him as a DEA agent. He was subsequently arrested and faces charges relating to the alleged forged credentials, firearms and drugs.
Police later searched his Olney home.
Inside, investigators found what they described as hidden spaces containing dangerous chemicals, a small marijuana-growing operation and a 55-gallon drum connected to hoses and other piping. Authorities also recovered what police described as 120 pieces of ballistic evidence.
The most significant discovery, however, was the enormous collection of digital material.
Philadelphia Police Department Deputy Commissioner of Investigations Frank Vanore said investigators had recovered more than 1 million digital images. He said the collection contained large numbers of photographs showing women in different positions inside the house.
Police said several of the images appear to show women who have been reported missing and were last seen with Eugene Horsch. Some videos also appear to feature R.C. Horsch. Police said none of the videos reviewed so far include Eugene.
Investigators have identified 58 people in the material. Police said 16 have been found alive but are not cooperating with investigators, while another 25 have been located and have interviews scheduled.
Five people appear lifeless or unconscious in some of the recovered material, according to police. Investigators believe they know the identities of four of them.
Vanore cautioned that the footage does not by itself establish what happened. He said some of the videos appeared to involve 'play-acting', while other events could be real.
Five Missing Women Connected to the Olney Home
Police have identified at least five missing women as being connected to the property. They are Gabrielle Amarando, Maribel Fresses, Nicole Fusaro, Amy McHale and Tonzelli.
Amarando, 27, has been missing since 2012. Police said images recovered from the house show her in material dated to 2017. Fresses, 26, who has also been missing for years, appears in images dated to the same year.
McHale has been missing since 2016. Her family has said she left her daughter a voicemail on the night she disappeared, indicating that she was at the Olney property with R.C. Horsch.
According to McHale's daughter, Amanda Stofer, her mother and R.C. had known each other since the 1990s. They married, later divorced and remained friends, according to the family. McHale reportedly went to his home after an argument with her mother.
One video recovered from the property shows R.C. Horsch with a woman who is naked, according to police. At one point, he appears to handcuff the woman to a bed and place a zip tie around her neck. Vanore said the woman becomes unconscious and appears lifeless in the footage.
This story is INSANE. A father/son generational serial killing duo was uncovered in Philly. These psychos were DISSOLVING the bodies, but kept photo and video evidence. The father died and the son kept on. Please pray for the victims. It wasn’t just five, it’s countless ATP. https://t.co/uuAPg0IG5Q

But the police official stressed that investigators had not recovered a body and still needed evidence to establish what actually happened.
'We still need to find evidence to corroborate what appears to have happened in this video,' Vanore said.
Police also found five urns they believe contain human remains. Investigators believe one may contain R.C. Horsch's remains, while another is believed to contain his sister's ashes and a third those of a friend.
As of Wednesday, however, authorities had confirmed no human remains at the property belonging to any of the missing women.
That leaves investigators working to establish which parts of the digital evidence reflect real events and what ultimately happened to the women whose disappearances have brought renewed attention to the Olney house.
