The case of Eugene Albert Horsch has captured national attention after he was arrested at what seemed like a routine traffic stop near Independence Mall.

And for weeks, it has only gotten stranger.

Police say they believe that at least three women were killed in Horsch's Olney home — a dilapidated, mysterious property at the center of the investigation. Horsch, 44, remains in federal custody on illegal gun possession and related charges, and has not been charged with any violent crimes.

For weeks, federal and local authorities have been searching his house on the 400 block of West Chew Avenue, turning up mountains of bizarre evidence. At least two other women connected to Horsch and his late father, Raymond "R.C." Horsch, were last heard from at the property.

Unknown chemicals, falsified law enforcement credentials, urns, and disturbing writings have been uncovered in the home since searches began two months ago. Answers into what exactly was going on there, however, remain elusive as the investigation continues.

Here is how it has unfolded so far:

June 19

Horsch’s arrest

Horsch's initial arrest in the case came after what started as a routine traffic stop near Independence Mall. A U.S. park ranger saw Horsch's black BMW stopped on Sixth Street in a restricted area, and approached the vehicle to speak with the driver.

The ranger, police said, heard a woman in the vehicle say, "You're going to hurt me." She then produced an ID identifying herself as Blair Tonzelli, a 38-year-old woman who was reported missing in February 2023 — an alias the passenger said she used because of open warrants for her arrest, sources told The Inquirer.

Police searched Horsch's vehicle, and recovered two firearms with obliterated serial numbers, along with cocaine, fentanyl, and marijuana, according to an affidavit. Police, sources said, also found a fake U.S. Drug Enforcement badge with Horsch's photo on it next to the name "Eugene Frederick Steiner," as well as switchblade knives, a cattle prod, and a collapsible baton.

Horsch was arrested and charged with illegal gun possession and drug crimes, and was held on $500,000 bail at Curran-Fromhold Correctional Facility. Federal drug enforcement officers, with assistance from Philadelphia police, began searching his Olney home that day.

Searching the Chew Avenue house

After a week of searching, investigators had uncovered a trove of bizarre items. Among them, Inspector Raymond Evers later said, were a home lab in the basement, a marijuana grow operation valued at about $280,000, and a number of containers filled with an unknown oily substance.

Investigators also found an illegal gun, a fake FBI badge with Horsch's photo, five urns containing what police believe are cremated human remains, bottles of liquid investigators could not immediately identify, and a 55-gallon drum with water lines leading to a hole in the ground, according to an affidavit. Additionally, the search revealed bank cards in Tonzelli's name, and an unsigned handwritten document that referenced serial killer Ted Bundy, among other items.

“We just don’t know what he’s doing, if he’s producing something, if he’s making something, if he’s irrigating something," said Deputy Police Commissioner Frank Vanore at the time. "We don’t know."

As the search continued, suspicions were renewed about Horsch's late father, Raymond Horsch, who died last year. The elder Horsch's ex-wife, Amy McHale, was reported missing in 2016, and, like Tonzelli, was last heard from at the Chew Avenue house. Police, however, said that it was too early to say whether any of the evidence recovered would reveal anything related to Tonzelli or McHale.

“This is much ado about nothing,” said Horsch’s attorney, Jerome Brown, of the missing persons investigation at the time. "They're barking up the wrong tree."

June 30

Horsch held in federal custody

Horsch was arraigned on a federal firearms charge in connection with his June 19 arrest. Previously, city prosecutors charged him in the case, but with the federal charge, Horsch would be unable to post bail and would remain detained until trial.

During an appearance in federal court, Horsch spoke little beyond responses to routine legal questions.

About a week later, federal prosecutors formally indicted Horsch for illegally possessing firearms and fake federal law enforcement credentials.

“We believe Mr Horsch is innocent," Brown, Horsch's attorney, said in July.

Excavation at Horsch's home

In the month that federal and local authorities had been examining Horsch's house, investigators used a number of tools, including canine teams from the New Jersey State Police. But by late July, the focus turned to what was beneath the property.

Authorities announced they would unearth a pipe under the house, and examine it for "any evidence that may be present," said Philadelphia police spokesperson Sgt. Eric Gripp. That pipe, Evers later said, was a sewer line.

On the day of the excavation, investigators began digging early, tearing through a small, overgrown garden, as well as the sidewalk and street in front of the property. In the late morning, investigators, with assistance from the Philadelphia Water Department, pulled a piece of pipe from the ground and took it to be examined.

July 24

No blood or DNA found

Earlier in the search of the Chew Avenue house, law enforcement sources said investigators had found what appeared to be a significant amount of blood. That suspected blood, however, was later determined to not be real blood, and forensic testing found no DNA belonging to Tonzelli or McHale, sources said.

Days later, Evers said, more than 20 containers of an unknown substance found in the house were delivered to a lab in Chicago for testing and analysis.

Early August

Two new victims identified

During the search of Horsch's home, investigators discovered about 50 hard drives and other electronic devices, and sent them to the Regional Computer Forensic Lab. In total, those devices contained more than 60,000 images, 70,000 videos, and 10,000 pages of writings and drawings.

In early August, during the search of a hard drive, investigators found what Evers described as images and video of "what appeared to be two deceased females." Those women have been identified as Maribel Fresses, who was 27 when she went missing in February 2018, and Gabrielle Amarando, who was 22 when she went missing in September 2012.

Neither woman had previously been linked to the case, but police believe they were killed inside the Horschs’ Olney home. Investigators, however, had not recovered human remains in the home, Evers said. Police are trying to determine when the women died. They have stopped short of blaming either Horsch.

Evers added that after reviewing the photos and video, the Philadelphia Office of the Medical Examiner said that "if the images and the video are real and not altered in any way," the women were dead.

Aug. 6

Feds take over

The Philadelphia District Attorney's office announced that it had withdrawn the charges it had filed against Horsch. With that change, federal prosecutors were able to take over the case.

Horsch had been in federal custody for more than a month at this time following his arrest in June. Neither Horsch nor his attorney appeared in court during the hearing where Assistant District Attorney Alyssa Amoroso withdrew the charges.

Aug. 12

New developments announced

After nearly two months of the investigation into Horsch's home, police provided an update on the case, and identified Fresses and Amarando as suspected victims.

Hours before a news conference announcing the new developments, authorities contacted the women's families, Evers said. The "graphic and dark" depictions of what appeared to be their dead bodies, he added, seemed to confirm their deaths.

Ricardo Fresses, 61, said that deep down, he knew his daughter Maribel Fresses was dead.

“She called me every day. Absolutely every day she called me, and one day she stopped calling me,” he said. “And as the years went by I knew she was gone.“

Lora Timmons, Amarando’s stepmother, said she was devastated by the news.

”I always hoped I’d see her again," she said. “I didn’t want to think the worst.”

Because their bodies had not been found, the medical examiner's office cannot declare the two women dead. Authorities expect a "protracted" investigation, Evers said, and any declaration of their deaths would likely have to go through Orphans' Court.

In total, Evers said, authorities had served more than 95 search warrants on the property to discover an "astonishing" amount of evidence. Investigators, he added, had only reviewed about 5% of the digital materials, and it was not yet clear when the women died.

“Eugene lived there. He lived there for a long time. His dad lived there for a long time,” Evers said.

Fifth missing woman linked to Olney house

As investigators continued to review digital evidence from the home on Chew Avenue, they found what they believed was video footage showing Raymond "R.C." Horsch killing a woman on camera, law enforcement sources said.

The footage, which police found on a hard drive inside Horsch's house in Olney, appeared to show the older Horsch strangling the woman at his home. Police did not disclose the woman's identity, but notified a relative, the sources said.

Investigators had not recovered the woman's body, and it was unclear when the footage was taken. But with the video's discovery, the woman became the fifth known missing person tied to the Chew Avenue property.

Sources told The Inquirer that police expected the number of missing women connected to the home to grow as the investigation continued.

Latest victim publicly identified

Family members identified the fifth missing woman tied to the Chew Avenue house as Nicole Amanda Fusaro, who had been missing since July 2018.

Fusaro was 27 when she went missing, and was last seen in Kensington. She was raised in Northeast Philadelphia, and attended George Washington High School, according to her Facebook page. A family member told The Inquirer that Fusaro's parents both struggled with addiction, and that she began using drugs in her late teens before drifting to Kensington.

Investigators previously recovered a video on a hard drive taken from Horsch’s home while in search of clues for other missing persons linked to the property. Law enforcement sources said they believed the video shows the older Horsch strangling Fusaro to death.

“Hopefully more attention will be made to missing persons so this doesn’t happen again,” said Jonathan Halloran-Koren, Fuscaro's cousin.

Sept. 16

Seven dead or missing women linked to Olney house

The number of dead or missing people linked to Horsch's Olney home increased to seven after investigators recovered images that appeared to show two more women dead inside the property, Deputy Police Commissioner Frank Vanore said.

Among the images, Vanore added, were photos that showed a 25-year-old woman unconscious inside the home with injuries on her body. Vanore declined to identify the woman at her family's request.

Additional images showed another woman who appeared to be dead inside the property, and investigators have not yet identified her. She appeared to be in her mid-20s, Vanore said.

In total, investigators identified 58 people in digital evidence collected from the home, Vanore said. Of those, 16 were located and interviewed by police, and 25 others were located but not yet interviewed.
