I think the biggest problem for her parents, if they have no involvement, is that the picture they have painted of their daughter seems to differ massively to what is coming out now. I thought she was a shy, insecure and socially inept young lady, who rarely ventured from her home, unless accompanied. Now it seems that she had a troubled teenage period, bunked school, failed exams, had difficulties with her parents, and has "disappeared" before (or at least been gone a while without them knowing where she is). Why would anyone describe someone who is missing with no relevance to what they are really like, as surely that would impede the investigation?
Hope my initial suspicions are wrong though, and hope she comes home. Doesn't seem very hopeful
