Suspected Philly Serial Killer's Manifesto Reveals Eco-Anxiety, 'Feminist' Ideals

The late Raymond "RC" Horsch, a Philadelphia-based pornographer and filmmaker suspected of being a serial killer, espoused environmental concerns and a warped sense of feminism in a self-published manifesto, according to an investigation by the New York Post.

Horsch's 2023 book, "Worldview: A User's Guide to the Human Brain," presents him as a Nietzsche-loving atheist concerned with social justice and the environment. In the text, he referred to humans as "an insignificant lifeform" and lamented pollution, writing, "The human species is analogous to a cancer," and expressing distress over "resource rape, pollution and carbon emission."

He also wrote about the urgency of climate change, stating, "The ice is not going to stop melting and sea level is not going to stop rising. Depleted ocean oxygen levels, mostly due to the massive dumping of waste and plastic, are causing irreversible extinctions and loss of entire ecosystems."

Despite these pronouncements, Horsch is linked to the disappearances of at least seven women. Police discovered over a million pieces of graphic digital evidence, chemical equipment, and weapons inside the Olney neighborhood home he owned. The investigation was triggered in June 2026 when Horsch's son, Eugene, was arrested on a minor traffic violation and his female companion produced the identification of a missing woman.

Within the Chew Avenue residence, authorities reportedly found disturbing recordings documenting severe abuse, asphyxiation, and alleged strangulation of missing women. Urns containing ashes and containers of unknown oily substances were also recovered, though no human remains have been positively identified.

Horsch, who died in 2025 at age 82, also referred to himself as a "feminist" and "caring predator." In a 2006 interview with UK's Bizarre magazine, he reportedly stated, "my obsession is sex. Dark, fetid, extreme sex… do I get aroused by young women (some beautiful) shooting heroin? I surely do." His writings also touched on ending racism, advocating for diversity in thought, intellect, social custom, race, ethnic heritage, and gender.

Investigators are examining at least three other self-published works of fiction by Horsch from 2013 and 2014 for clues. In one of these books, "Empathy: The Memoir of an Empathic Serial Killer," the protagonist allegedly smothers a desperate addict named Krista, whom he met in Philadelphia's Kensington neighborhood. The narrative describes disposing of the body with lye and then preserving the memory through photographs.

The protagonist in "Empathy" also hints at suffocating his own elderly mother with a hospital pillow. Little is known about Horsch's biological mother, beyond her role in raising him in Bucks County.

For over 40 years, Horsch used the stolen identity of Dr. Stanley Stokowski, a Stanford University physicist. He reportedly used this alias in the 1980s to obtain employment at a chemical plant in New Zealand while evading U.S. authorities. He also allegedly used the identity for a fake online persona that posted favorable comments about him.

The real Stanley Stokowski, now 83, expressed bewilderment at Horsch's use of his name, noting that Horsch showed an interest in physics and science fiction in his manifesto. Stokowski confirmed he was never contacted by Horsch. A source at "Sesame Street" stated there is no record of Horsch's alleged employment on the show's pioneering 1969 season.

Horsch's past includes a 1984 capture in New Zealand while living under the Stokowski identity and evading U.S. law enforcement after jumping bail for a 1977 meth lab bust. He had previously been arrested and convicted in 1974 for counterfeiting $10 bills totaling $180,000.

A 1985 psychological evaluation described Horsch as an "extremely bright man" who was "erratic but prolific," harboring a desire for a secluded life focused on quantum physics. The evaluator also characterized him as "grandiose, mistrustful, suspicious, and excessively controlling."

In 2014, Horsch exhibited photography at a Kensington gallery, which included depictions of nude women in violent and degrading situations. A review at the time questioned if the exhibit was "a catalog of victims?"

The named missing women linked to Horsch include Gabrielle Amarando (22, missing 2012), Maribel Fresses (26, missing 2018), Nicole Fusaro (27, missing 2018), Blair Tonzelli (35, missing 2023), and Horsch's ex-wife Amy McHale (44, missing 2016).
