Do we know if the GF and/or Dad are smokers? I am having a hard time buying this we lock the doors all the time thing. Now I am paranoid and don't trust people so my doors are locked and my German Shepherd will tell me you are there long before you can get to the door, but a friend of mine is a smoker with a kid, lives in a much less safe neighborhood than I do and she never locks the door because she is in and out to smoke all the time.
And what was the GF wearing when the cops arrived? I want to see a police report. Was she in worn jammies with hair that had been slept on for five hours? Was she in regular clothes? Or had she quickly thrown her jammies on while trying to figure out where the hell Haleigh was before dad could get there (which is where I think the 30 minutes between discovery and 911 went). She was hoping she was hiding and that she could "fix" this. If she truly rolled out of bed and found the child gone and door open 911 would have been called much faster.
