I read,, I believe, that she was the oldest of 4 children, I wonder if she shared a room with a sister.<modsnipped> If she left voluntarily with her phones, she must have been meeting someone, because there is no logical place for her to walk to between midnight and 4 AM (google maps). That sort of eliminates her being picked up randomly by someone, because why would she be out there and how would they know it. To much coincidence for me. Also, if her phone pinged just over the border in Kentucky, all that means is that the phone was there and doesn't prove it was in her possession,unfortunately.
I wonder if she had a friend who could drive, from her last home in Georgia, who came and picked her up.
