"Haleigh was discovered missing from her home Tuesday morning by her father's girlfriend, Misty Croslin. The father, Ronald Cummings, said Haleigh had gotten up to use the bathroom, and when she didn't return, Croslin went to look for her and noticed the back door of the mobile home they shared was open."this is the first I've heard that this is a mobile home ... okay that makes it even more suspicious that it was someone on the inside.
Two of my brother's have lived in mobile homes ... the side door is always the main entry, then the emergency exit, or as they call it here the 'back door' is located in the back bedroom ...
even if they had remodelled the home, we are talking about an area that you can cross in maybe 5 paces, oh okay 10 paces at most ... but still the walls are so thin that I can not imagine that anyone could enter without you hearing something.
the walls are little more than a 2X4 frame with wooden paneling used as walls, okay maybe a little foam core but that's it.
either that girlfriend was in on this or the father was ... I'm leaning towards the girlfriend myself ... but you never know.
