Les as even you appear not to have a clue why you think she is guilty, but you still think she is. That's as logical as saying you believe in Santa Clause because some people have white beards !!!!!!
As I keep saying unless one has an intimate knowledge of the evidence (which probably only the investigating officer has) then it not possible to have a reasonable opinion.
Thus, in this case, any opinion is a wild guess and nothing more. But I don't expect anytime soon Les you will see the logic of that.
If I were to make a 'professional guess' from what I have seen on TV, I would say the Italian police lost the plot and were totally out of their depth and happy to stitch up anyone who was available. In just the way the Portuguese police were in the Maddie McCann case. Incompetent beyond belief.
But as I don't guess ...........
