Yes, this is also what I think. I thought this since yesterday as I don't believe a live girl would be found by/in the river. The way the river was flowing and the vicinity of the car to it doesn't sit well. Coupled with the fact witnesses have heard reports of tyre tracks on the banks where a car just wouldn't go.
I still hold out some hope and I know there is a hell of a lot of information being held back by the police, I can feel that they know a lot more than they're letting on. The confusion over the vehicles, the fact they're not saying why Mark Bridger is a person of interest etc. I think something is going to break through today. Just have to sit and wait
Also can I just say that I want to punch the Mccans in the face for trying to get involved!
