OK, I can't find the picture - sigh...on NG last night at the beginning there was video of the back of the trailer. I noticed the A/C unit on the back corner by the back door ramp. Now, if you have ever had your A/C serviced, you know that the guy comes in and out, in and out from the outside unit to the inside.
My suspicion is that he opened and propped the door to do the service. When done, forgot to shut the door behind him because he came into the house to talk to gf about what he did and get a signature, etc. He probably left by the front door.
Maybe he just pushed the door towards closed but since it is hard to close and requires pushing hard to lock, it didn't close all the way. Screen was still propped open with cinderblock...he could have even left through this back door and the door didn't close properly.
I don't think gf did anything other than maybe something mildly neglectful and opportunity was there for the "bad guy/girl"...
Gf maybe didn't check it before bed like she said and is afraid to say so because then this would be her fault in her eyes (and dad's eyes). Or maybe she did check it every night or most nights and just THINKS she did this night. How's this sound?
Only thing that doesn't compute is if she did laundry that night and the laundry room is right by the door - she would have noticed it open...:waitasec: Kitchen light also doesn't compute...
