Can you please tell us what you think happened to Claudia all them years ago ?What I am getting at is anyone can jest pluck out scenarios from their imagination - why is she at home? What makes us believe she is at home? What proof do you have confirming she is at home when her mother calls? Alleyway man could be the local pools coupon collector. No one knows who he is (for sure) in 11 years there is no concrete version of events, nothing - no one on here is any nearer than in 2009. And I can be fairly sure no one will be any nearer ten years from now - so save your time and do something else.
Feel free to say ‘not a clue ‘ if this is the case .
