Self-described serial killer Raymond Horsch, whose Philadelphia home connects to seven missing women, allegedly filmed himself strangling Nicole Fusaro

An 82-year-old Philadelphia resident was connected to the disappearance of at least seven women after investigators discovered more than one million explicit photos and videos, authorities said.

Raymond “R.C.” Horsch, who died last year at the age of 82, lived with his adult son at the property in the city’s Olney neighborhood.

Philadelphia police announced the findings on Wednesday, September 16, according to NBC News.

Five of the seven missing women connected to the property are believed dead, police said.

The residence has since been called a “house of horrors,” according to NBC News.

The investigation into the home began after a park ranger spotted the resident’s son illegally parked at Independence Hall in June, according to NBC News.

The son was identified as 44-year-old Eugene Horsch, police said.

The ranger encountered the younger Horsch with a woman who had a missing woman’s identification card, according to police.

That woman, Blair Tonzelli, vanished in 2023, NBC News reported.

Authorities also located guns, drugs, a cattle prod, and a fake badge purporting to belong to a federal drug enforcement agent in the vehicle, The Philadelphia Inquirer reported.

That discovery prompted a weekslong search at the Olney home, according to the newspaper.

Officers searching the residence discovered drugs, weapons, and tubs of unknown fluids, per the newspaper. Investigators also found a 55-gallon drum connected to a water line, according to the report.

The property search unearthed more than one million photos and videos, authorities said.

Many of the files were gruesome images appearing to show several women harmed, dead, or unconscious, according to police.

Investigators have so far identified 58 people shown in the digital images, Philadelphia Deputy Police Commissioner Frank Vanore said.

Four of those identified individuals looked dead or unconscious in the recordings, Vanore said, according to NBC News.

Detectives have located 41 of the people identified in the files, police said. Investigators are still trying to interview 25 of those individuals, according to Vanore.

One video appeared to show the elder Horsch fatally strangling a woman with a zip tie, The Philadelphia Inquirer reported.

The footage reportedly showed the woman consuming drugs before Horsch handed her money, according to Vanore. The elder Horsch was allegedly naked when he handcuffed her to a bed before strangling her, the newspaper reported.

Family members identified the woman in the recording as 27-year-old Nicole Fusaro, the newspaper reported. She disappeared in 2018, according to the outlet.

Other missing women linked to the Olney house include Amy McHale, Raymond’s ex-wife who was reportedly last seen at his home in 2016, according to NBC News. The outlet did not specify McHale’s age.

Investigators also linked 27-year-old Maribel Fresses, who has been missing since 2018, and 22-year-old Gabrielle Amarando to the house, according to NBC News. The identities of two other women have not been shared by law enforcement, authorities said.

Before his death, the elder Horsch had written several books featuring disturbing and sexually explicit subject matter, according to CBS News Philadelphia. In one novel reviewed by the outlet, he wrote of killing a woman and disposing of the evidence using chemicals.

Horsch described himself as an “empathetic serial killer” on a Google Books page for a 2014 memoir titled “Empathy,” according to records.

In an author section for another novel titled “Slaves,” he described himself as an “artist, filmmaker, composer, porn performer,” as well as a “fugitive, sociopath, ex-convict and all-out villain.”

Eugene Horsch was arrested on drug and firearm related charges in connection with his June encounter with a park ranger, according to CBS News. No arrests have been made over the alleged discoveries at the Olney home.

Information on legal representation for the 44-year-old son was not immediately available, according to reports.

To date, no human remains have been found at the house, according to authorities.
