Pickers said:Get back in contact with the parents to be honest... You must have SOME contact details? She's still in an unknown place. Appologise to mam for getting her up at 4am. I'll bet any money the mother isnt angry at you at all, and may even offer advice/shed some light.
To be honest though me ringing up and apologising to her is like admitting what I did was wrong - which it wasnt. I never actually got her contact details the police popped round so it would involve another call to them to try and get them to put me through to the ex directory number, think it would cause more hassle then its worth
