PHILADELPHIA (WPVI) — Investigators will, once again, descend on the Olney home at the center of a sprawling investigation into missing women in Philadelphia to begin a new phase in the probe on Monday.

The Chew Avenue house is where violent pornographer Raymond Horsch and his son Eugene lived.

Police posted additional “no parking” signs along the street Sunday ahead of the latest extensive search of the now-infamous Horsch home.

Last week, Philadelphia police and FBI began executing a fresh search warrant at the property, where investigators removed items of potential interest from the home to be cataloged as evidence.

Over the next few weeks, the FBI and Philadelphia police plan to bring in heavy equipment and actually take apart sections of the property, as they look for new evidence.

They will be guided in part by what they saw in hundreds of thousands of photos and videos collected from a prior search.

Sources tell Action News that the rest of the home will be cleared out on Monday before they likely bring up some of the floorboards and possibly remove portions of walls.

Sources also say investigators plan to spray luminol, which can reveal traces of blood not visible to the naked eye.

So far, seven missing women have been connected with the home through the recovered videos and images. However, no bodies have been found.

“I think of it like — it’s not like you’re trying to connect a puzzle, where you know what the picture is and you have these large pieces that you have to apply; instead, it’s like — you don’t know what the picture is, and you don’t have large pieces, you have tiny little dots. And every single tiny little dot needs to be connected perfectly so that you can get this picture of what actually happened in that home,” said former prosecutor Michael Noone.

Raymond Horsch died last year. He created movies that often depicted sexualized violence against women.

Now, investigators have to figure out what was staged and what was real.

His son, Eugene, was arrested back in June on firearms and drugs charges.

A subsequent search at his home revealed a more troubling mystery and prompted this massive investigation.

“Number one, you don’t have the body. Number two, you have this gap in time. Number three, you don’t have the actual cause of death. Did they die as a result of someone else killing them or did they die as a result of some other circumstance?” Noone said.

Officials say this portion of the investigation could last through October.
