I can't find the one of the thing staring out of the wall at the photographer... but I do have a copy of the one with the boy standing by the stairs.
His eyes are glowing white, and he looks exactly like John Matthew Defeo (one of the boys who was murdered in the house before the Lutz family moved in)
I haven't been able to find the images online either, but I uploaded that one onto this site here:
