Still no takers on this then?
Can't imagine why not.
I have stromg pointers against Bruckner, some mentioned before, but ignored by you.
There are others mentioned by Brietta and others, but ignored by you.
And there are others which I do not intend to share, but I have no actual proof. Therefore as far as I am concerned, Bruckner is innocent . but he is on the Back burner.
I think Bruckner is a driver, climber and enterer of buildings, He may have taken Madeleine up to Porto area, on the day after Madeleine was abducted, as witnessed by Carlos Moreira at the roadside cafe on the N10 (old main road up to Porto). I believe that he might later have transported her eastwards across Portugal, via interesting ...'sighting' towns to Barcelona and the Victiria Beckham look alike there BUT, I DONT KNOW for sure.
Therefore he is innocent. And if involved, he just works to the orders of the real perps. A paid handyman. IMO
I think that Wolters may well have been conned to give respite to the real perps. If I were the Police, I might be looking at some of his superiors to see their connections.
I believe that Madeleine is very much alive. Her outstanding bloodline is a treasure to someone
Everything above is from my opinion only, but based upon a great deal of deep research
