What gets me is that she went missing the night the sister she shares a room with happened to be out. I'd like to know how often that happened -- unless it's an awful lot, then I'd lean towards thinking the coincidence is just too great for this to have been a true stranger abduction. That is, either she left "willingly" (I put that in quotes, because that includes circumstances in which she was tricked into leaving by someone she had previously encountered) or someone with intimate knowledge of the family (a family member, a friend of the family/neighbor or someone a family member spoke to) was responsible.
(It's also possible that she was stalked by a stranger who, via their stalking, noticed her sister's absence that night, but that seems less likely to me given the totality of the circumstances -- e.g., she's only 11, she lived in a small town, lived on a main road, no one seems to have noticed anyone, etc).
