Nothing whatsoever, they shouldn't be using more resources than they would on any other missing child case. What I am saying is that the high majority of folks in the UK can believe in a god they have never seen, believe in miracles etc but cant for one minute believe that someone has played a blinder (relatively speaking) in kidnapping and withholding a child without getting caught?
Only this year think back to the house where three brothers had held some girls against their will for years and years, fathering at least one child etc. It can happen.
Oh, I agree, she may be out there somewhere but I don't think that it will make a blind bit of difference continuing the investigation. Those girls they just found in america were not revealed from police work, it was the lapse of the kidnappers after all those years. As long as the police presence is high in this case I would imagine that anyone who has managed to hide her away until now would take extra care till things have died down. That is if they ever relax and allow the opportunity for escape / discovery.
