i hate to say it , please don't hurt me
but IMHO, considering that residents there have said no one locks their doors and leave keys in vehicles ( well maybe not ALL, but that seemed the consensus)
I don't know that it really matters where what door was, or wasn't, or how someone got in...or out for that matter. Or what side of the house they lived or not.
None of us really know where in that house Celina was last...and who was inside the home, or when or nothing.......way too many details not provided by LE....
FYI a lot of people here leave their doors opened and keys in their car. That is NH Life. It is kinda like the 50's..
When my dog was lost we walked a square mile knocking on every one's door. It was the summer and everyone had their screen doors up. All you had to do was push it and you were in, and most of the time no one was home.
The police are being tight lipped.. but I think that may be a good thing.
