It's not looking good, is it? Although it's only 10 miles to her dad's house, he says she wouldn't have a clue how to get there on her own; and it sounds as if there's more to him not being in touch than just no money and broken-down cars.
An ex-boyfriend, RIR? I was wondering about the current one - he's only 22, and her mother says she's a "daddy's girl" with him and they play tickling games According to yesterday's Guardian her dad left 4 years ago, which is about when the 22-year-old (then 18-yr-old) arrived.
I agree that the police are holding back on any suspicions they have.
Poor little scrap.
