Investigators will return to the Chew Avenue house in Olney that is connected to the disappearance of seven women. They will be excavating the front yard.
On Tuesday, they dug up the backyard. Workers were also seen hauling away what appeared to be pieces of wood.
Earlier this week, investigators used the chemical luminol to look for bodily fluids around the house. During that process, they say areas of interest tested positive and may be further tested for possible DNA.
The house used to be owned by the late R.C. Horsch. Police say he preyed on women who dealt with addiction and used them in his pornography.
His son, Eugene, is in federal custody but hasn’t been charged in connection with the women who disappeared.
