Expanded perimeter in place as investigation continues at home in Philadelphia's Olney section
PHILADELPHIA (WPVI) -- Officials continued investigating a home in Philadelphia's Olney section on Monday, with federal agents on scene and an expanded perimeter remaining in place around the property.
Residents said access to the 400 block of Chew Avenue was restricted during the day. One resident said authorities had increased security measures compared with previous days.
"They had streets blocked off. There was no closure yesterday - today there is a closure," a resident said.
Sources said cadaver dogs were brought to the scene to assist investigators. Nearby residents reported seeing a dog searching the area near an orange tarp.
The FBI was also present at the property, with agents seen entering and exiting the home throughout the day.
The investigation is connected to 44-year-old Eugene Horsch, who is facing federal charges.
According to investigators, the federal charges allege Horsch, a convicted felon, was in possession of firearms and fake DEA and FBI credentials.
Aerial footage showed investigators working at the property, where shed doors in the backyard were open.
On the ground, many investigators were wearing protective suits. At one point, a person was seen carrying what appeared to be testing tubes from the property.
The investigation traces back to June 19, when officials said a park ranger noticed a black BMW parked in a prohibited area near Independence Mall.
According to court documents, Horsch and a woman were inside the vehicle, and the woman had identification belonging to a missing person.

Police said a search of the home uncovered an extensive amount of chemicals, drugs, guns and nearly 120 pieces of ballistic evidence.
Documents obtained by Action News show investigators also found zip ties, a handwritten note mentioning serial killer Ted Bundy and references to ways to dispose of trash.
"Every other day there's been a car out front that's it - making sure the scene wasn't being tampered with or going into the house," said one resident.
Investigators also found a 55-gallon drum connected to water lines. On Thursday, workers from the water department were seen at the scene.
Many questions remain as the investigation continues. Horsch is scheduled to appear in court in August.
