On June 19, 2026, a ranger at Independence National Historical Park spotted a black BMW parked in a space reserved for law enforcement, a stone's throw from the Liberty Bell. He walked over expecting a confused or arrogant tourist. Instead he heard a woman's voice from inside the car: "You're gonna hurt me."
The driver was Eugene Horsch. What police later pulled out of his house in Philadelphia's Olney neighborhood has the city asking whether a father and son spent decades getting away with murder.
A badge, a cattle prod, a borrowed name
Both people in the car were covered in sores and, as the police report put it, engaged in illegal drug activity. The search turned up crack cocaine, a switchblade, two guns and a cattle prod. There was also a badge with Eugene's photo on it identifying him as an agent of the DEA, the Drug Enforcement Administration. The passenger's photo was on another ID, but the name belonged to Blair Tonzelli, a woman missing since 2023. Blair often stayed at Eugene's house for long stretches, and it was the last place anyone saw her alive. When her friends reported her missing, they named Eugene and called him a sociopath.
The passenger told police she had no idea who Blair Tonzelli was. Eugene had never hurt her, she said, but he had mentioned that he knew "which chemicals were needed to dissolve a human body." Well, hello, probable cause.
What the basement held
The house on West Chew Avenue had belonged to Eugene's father, Raymond Charles Horsch, known as R.C., who died in 2025. Philadelphia police and the FBI spent weeks digging up sewer lines and prying open hidden compartments. They found vats and barrels of chemicals, 50 containers of an oily substance that went off to a federal lab in Chicago, and a 55-gallon drum hooked up to water lines in the basement. They found Blair's bank card and more fake IDs in her name. They found an unsigned, handwritten letter that described hurting people and gave a shout-out to Ted Bundy. On hard drives, they found 600,000 images and 70,000 videos. Police say some of that footage appears to show two long-missing women dead inside the house: Maribel Fresses, who vanished at 27 in 2018, and Gabrielle Amarando, who was 22 when she disappeared in 2012.
Then there was Amy McHale, R.C.'s third wife. She met him on the streets while she was sick with pneumonia. He was 30 years older and nursed her through it, and her mother said Amy saw him as her savior. The marriage didn't last, but Amy kept coming back. On June 14, 2016, she left her daughter a voicemail saying she was at Ray's and everything was okay. Nobody heard from her again. R.C., who had always picked up when her family called, stopped answering. Eugene was in state prison at the time.
A villain by his own résumé
R.C. Horsch was born in Stroudsburg, Pennsylvania, in 1943. An author's bio called him an "artist, filmmaker, composer, writer, porn performer, drug smuggler" and, further down the list, an "army deserter, fugitive sociopath, ex convict and all out villain." In 1973 he directed a truly odd adult film, The Erotic Memoirs of a Male Chauvinist Pig. He passed bad checks and counterfeit $10 bills and was caught with phony driver's licenses. In 1977, after police found a meth lab, he ran to New Zealand. Posing as Dr. Stanley Stokowski, a man with a doctorate from Stanford, he landed a job at an alternative-fuels company turning whey, a dairy byproduct, into ethanol. He was caught in Florida in 1985. In 2009 it was illegal shotguns and more than 450 pot plants.
His second wife, Anna Ferkuniak, married him under the name Stokowski and gave birth to Eugene, his only child. She died in 1989 at 39. Her obituary blamed a lengthy illness. The real cause was an overdose of codeine and the sedative Doriden. Nobody has proven R.C. killed her. About 25 years later, he published her diary as Annie, complete with a foreword in her voice.
In 2014 came Empathy, which he pitched as an "autobiographical memoir of a caring, empathetic serial killer." In it, he strangles a woman named Krista, buys a 100-pound drum of sodium hydroxide, better known as lye, and lays her body in a bathtub in his basement. "Soon the liquid boils. The heat is good because it greatly speeds the decomposition process. In five or six hours, there'll be nothing left of her." He also liked to ask his readers, "but what if I'm lying?"
R.C. Horsch published a book about a serial killer who dissolves a woman in lye in his basement bathtub. Police later found vats of chemicals and a drum plumbed into his real basement, where missing women were last seen alive, and the method he described leaves no DNA to find.
Like father, like son
R.C. trawled Kensington Avenue under the elevated train tracks, offering women money or drugs to pose for his camera. He ran a website full of violence, with a running theme of young women shooting heroin. He compared himself to the snake in the fable that bites the woman who raised it, "because it is my nature."
Eugene was a straight-A student who never graduated from high school and got into Drexel University in 1999 on a forged diploma. In 2003 he drove drunk, ran a red light and plowed into another car. The other driver spent 16 years in a vegetative state before dying. In 2013 police found $1.9 million worth of cannabis in the house. In March 2025 he was charged with stabbing a man in the stomach at Eighth and Market. The charges were dropped when a witness didn't show up to court.
That same year, three days after R.C. died, a fire tore through the second-floor bedroom of Krista, a woman who lived in the house and had just lost a leg to amputation. Officially, a lit cigarette started it. Krista died of an overdose that August. Eugene posted on her Facebook page that the two of them had been in love and planning to marry. They weren't.
A funeral you could drink
Investigators were looking for signs of wet cremation, known formally as alkaline hydrolysis. A body goes into a heated bath of 95 percent water and 5 percent lye. In four to 16 hours, depending on the heat, the flesh is gone, and the bones are left to be ground into a soft white powder. What's left of everything else is a sterile effluent, a broth of salts, sugars and amino acids that is safe to pour into city sewers and carries no trace of DNA. The process is legal in 26 states, and Archbishop Desmond Tutu asked for it. One Oregon funeral director declared that "you could drink the stuff and be just fine."
That no-DNA part is the problem. Early tests picked up what looked like a lot of blood, but later tests came back negative, and the blood turned out to be fake movie blood. Neither missing woman's DNA turned up on anything tested. In August 2026, a federal grand jury indicted Eugene only on gun and fake-ID charges. He remains in custody, and the house on West Chew Avenue is still giving up its secrets.
