Philadelphia Police Investigate Suspected Serial Killer's Home, Uncover Extensive Digital Evidence

Investigators are meticulously examining a Philadelphia home connected to Raymond 'RC' Horsch, who died last year at age 82, as they believe five women associated with the property are dead and two others remain missing. The grim discovery stems from an investigation that began in June 2026 when Horsch's son, Eugene, was stopped by police.

During that stop, a woman in the vehicle identified herself as Blair Tonzelli, who had been reported missing in 2023. Police also found illegal drugs and firearms in the car. Eugene Horsch allegedly indicated that Tonzelli would never be seen again, prompting authorities to execute search warrants on his father's Olney residence.

Early searches of the property revealed illegal firearms, a counterfeit FBI badge, a marijuana cultivation setup, and five urns containing cremated remains. A subsequent search uncovered over 50 hard drives containing more than 600,000 images, 70,000 videos, and numerous writings and drawings.

Deputy Police Commissioner Frank Vanore stated that officers have reviewed over 1 million digital images and videos from the home, identifying 58 alleged victims. Five of these women appear lifeless or unconscious in the footage. Sources familiar with the investigation identified three of these individuals as Gabrielle Amarando, Maribel Fresses, and Nicole Fusaro. Amy McHale, Horsch's ex-wife, and Blair Tonzelli are among the missing.

Evidence from the hard drives led investigators to believe Amarando, who disappeared in 2021 at age 22, and Fresses, who vanished in 2018 at age 27, are deceased. Video files dated 2017 show Fresses and Amarando unconscious with visible injuries, though their bodies have not been recovered. Other footage from the same year reportedly depicts Horsch with a woman, identified by sources as Nicole Fusaro, who disappeared in 2018 at age 27, before she appears to lose consciousness after being bound and having a zip tie placed around her neck.

Ten other individuals seen in the videos reportedly overdosed and were found in various locations across Philadelphia. Sixteen others were found alive but were reportedly uncooperative or unwilling to speak with investigators. Authorities are currently attempting to contact 25 additional alleged victims identified from the digital evidence.

The investigation has also prompted a re-examination of the disappearance of Amy McHale, Horsch’s former wife, last seen at the Olney property in 2016. Horsch, known for his work in violent pornography and writing books about serial killers preying on women, has been linked to these disappearances.

Eugene Horsch remains in federal custody on weapons charges and has not been charged in connection with the missing women. Investigators have so far reviewed only about 30 percent of the digital evidence.

Authorities are awaiting test results on chemicals found in the home's basement that could have been used to destroy evidence or dissolve remains. The FBI and Philadelphia Police have pledged a thorough investigation to provide answers to the families of the missing. Anyone with information is encouraged to contact the Philadelphia Police Department.
