Isn't that what happened very recently with the handbag of Jill Meagher? Wasn't her bag was found down a side street, placed by a car and initially it was thought it could have been put there by the perp to confuse the police investigation? Turns out someone had picked it up, and then left if there when they realised the significance of it ... I think I'm remembering correctly, but correct me if I'm wrong.
Praying little Jessica is found unharmed, and thinking of her poor mother who must be going through hell. I'm a working single mum, and on my days off when the children are at school, I often go back to bed - and could easily sleep through a phone call. I hope she isn't blaming herself, as she did nothing wrong.
