New details link 4 missing women to the Olney ‘House of Horrors” as investigators continue to sort through evidence

There’s a case playing out right now at a home on Chew Avenue in Olney that keeps getting more disturbing the deeper investigators go, and it’s worth laying out plainly because of how staggering it’s become.

Philadelphia police say detectives found graphic digital evidence inside the home of 44-year-old Eugene Horsch that appears to show two missing women deceased. The two are 27-year-old Maribel Fresses, last seen in 2018, and 22-year-old Gabrielle Amarando, who hasn’t been seen since 2012.

Investigators say injuries were visible in the images, but here’s the chilling part: the medical examiner can’t issue an official cause of death, because neither woman’s body has been recovered. Police believe these women are dead, and they don’t have them.

At least 4 missing women have been linked to the Olney home so far…

What makes it even harder to wrap your head around is that police say they’ve only reviewed a small fraction of what was on that hard drive. The full amount is more than 600,000 images, 70,000 videos, and over 10,000 pages of writings, manuscripts, and drawings.

That’s an almost incomprehensible volume of material, and investigators are openly bracing for a long, sprawling case. They haven’t ruled out more victims, either.

The whole thing came to light almost by accident.

Back in June, police arrested Horsch in Center City after finding him and a woman in a vehicle with drugs, two loaded guns, and a fake DEA badge. The woman was carrying a fake ID belonging to Blair Tonzelli, who had herself been missing for years.

That single traffic stop is what led investigators to the Olney home, and everything they’ve uncovered since has only gotten darker. Detectives are now working alongside special victims and missing persons units and comparing DNA against women who’ve gone missing from Kensington.

Amy McHale, missing since 2016, is also tied to the home, though police say they haven’t yet found digital evidence connecting her or Tonzelli to the scene.

From the portion of footage they’ve reviewed so far, Inspector Ray Evers said some of the people seen in the videos are alive and have already been interviewed. Others are still missing.

That detail alone tells you how wide this thing could get. The property remains cordoned off, the investigation is nowhere close to finished, and police fully expect to return to the house as they keep digging.
