Dressed in white haz-mat suits, investigators hauled out two chairs, a couch and a carpet -- each wrapped in brown paper -- from the Kensington living room of the 35-year-old Aron, who was charged in Tuesday's killing and dismemberment of the angelic Borough Park boy.
Over the weekend, two mattresses also had been hauled out of the house Aron shared with his dad, stepmom and uncle.
Police are still working from a search warrant to retrieve more evidence that might yield any DNA that could bolster the murder charges against Aron.
LEIBY'S FAVORITE SINGER PAYS VISIT, TRIBUTE TO FAMILY
Cops believe that the twice-married Aron was "simple-minded" and appeared to have acted on just a bizarre "fondness" for kids, freaking out after snatching the boy, a source familiar with the investigation told The Post.
But "you don't know what you'll find," another law-enforcement source said. "You don't go in with preconceived notions."
Leiby was snatched from the street exactly a week ago after getting lost walking to meet his mother on his way home from Nechmod Day Camp.
The tragic child had asked Aron for directions when he was allegedly abducted by the man.
Aron has claimed that, after grabbing the boy, he drove Leiby 40 miles to a wedding ceremony in Rockland County later that night and then took him back to his apartment and smothered the child the next day in a panic amid the widespread search for the boy, law-enforcement sources have said.
Cops are still poring over wedding video for any signs of the boy there, sources said.
Politicians who visited the grieving Kletzky family said yesterday that Leiby's dad, Nachman, spoke about ways to make the neighborhood safer.
"He's thinking about what we could do about security cameras to make sure there are no more Leibys," said City Councilman Brad Lander.
"He was asking us what it would take to have more security cameras not just in business but homes, what things could we do to make sure that this could never happen again."
Existing security cameras helped crack the case, leading cops to the dental office that Aron had just exited when he came upon the child.
