I thnk it depends on which theory you follow /believe.

If you believe she was snatched from bed alive by paedophiles then , the chances of her still being alive after one week would be very slim.

If she walked an wandered and was knocked down by a passing car/found to be dead and was then lifted by the driver...

If she had an accident in the home and died ...

I just cannot see a theory where she would still be alive,unless she was abducted from the street after wandering- she could be a slave of sorts.

But then, her parents and supporters do not want this wandering looking for parents theory. So 95% chance she is not alive. IMO

Thanks for your answer. Can a parent's opinion have any bearing on the event. That is what I find strange about this case, in that we listen to Gerry saying Madeleine didn't get out and wander. How would he know?

I'm more of the thought that we are looking at the "residual possibilities". I don't know if that is a term used before but since so many things have been ruled out, what is left and what are the residual probability Madeleine is alive and it becomes higher, because there are fewer explanations left to work through.

But when it comes to calculating probabilities I've always struggled so I could be very wrong.
