From the Portuguese programme 'Sexta' Facebook page; 'The German prosecutor adds that he is in close collaboration with the Portuguese authorities and that there will be other crimes, other sexual abuse against children that will also have happened in the Algarve at the same time and that are under the target of the authorities.'
This is why it will take so long to get results, there are other crimes not just Madeleine.
I think they'll end up getting him for some of these other things.
