Dimples!
While you are there will you check and see if that big red box thingie (technical word, lol) on top of the 2nd building back has roof access or is just for decorative purposes, please? Not the building that sits kitty-corner and has the trailer but the building behind that one. It has a big red box on top, maybe just decorative but may also be roof access. I can't zoom in close enough to tell in map programs right now if there is a door to the roof on the backside. Can anybody else tell if there is a door or if that is just face front/decoration? Somebody either knew this family or had to have a view to watch them, unnoticed by others, in order to know which room was hers.
Even if that business is closed now it may have been a former employee.
If one were on the roof, I wonder if they could see the whole yard of the Celis' family. Things change a lot when you are higher up - perspective. Even if it appears from the ground that it is not a feasible idea it is amazing how different things look from up higher.
(I baked a cake and decorated it w/my GS today after I ducked out earlier. I feel much better now, lol. Cake and GS time fixes 'perspective'! )
