Etan Patz was last seen alive in 1979 in the area of the bodega.
On Wednesday, the NYPD went into a previously sealed room in the basement, possibly a room used to store coal.
Six bags of evidence were removed from the basement Wednesday.
Investigations determined the evidence removed contained nothing of significance. It was described mostly as old garbage.
Detectives also took new photos of the scene.
The NYPD returned Friday and is continuing their work in that closed area, including collection of more possible evidence and taking photos.
This is approximately the fifth time the NYPD has returned to this location since the Pedro Hernandez arrest. They have so far recovered no forensic evidence linking Hernandez to the death.
The FBI is not involved in today's search.
An assistant district attorney from the Manhattan District Attorney's office and a representative from the Medical Examiner's Office are both present at today's search, but they are also not involved in the searching.
Hernandez has been charged with 2nd degree murder in the case.
