DNA has been found inside the so-called Philadelphia ‘House of Horrors’ after months of searching, police sources told NBC’s affiliate in Philadelphia.

Search expands across property

The home is connected to several missing women. On Wednesday, federal and local teams are focusing their search efforts on the front yard of the property.

On Tuesday, investigators dismantled a shed in the backyard. As of now, nothing has been officially recovered to help determine what happened to the seven missing women tied to the property’s late owner, Raymond Horsch.

Police believe five of the women are dead.

Luminol reveals possible DNA evidence

Last night, investigators sprayed a chemical compound called luminol on the floors and walls inside the home. Sources said the chemical revealed locations of DNA, but it is unclear if the DNA belongs to any of the missing women.

Investigation draws strong community reaction

“Holy hell. I just couldn’t believe it. I’ve never seen anything so invasive in my life,” Tara Gallucci said.

“God only knows how many bodies are back there, and these are not just bodies or evidence. They’re people. They’re connected to loved ones,” Gallucci said.

Investigators hope to finish this phase of an investigation involving human remains before the end of the week, prompting strong reactions from local residents.
