That isn’t even a circumstantial case. Brueckner in or near PDL at the time...so we’re thousands of people and I’m sure several with a history of sexual violence. Not sure what you mean about the witnesses...have any of them identified Brueckner ? TS said the man she saw was extremely ugly and had a pockmarked face, Brueckner is neither ugly nor pockmarked. The another witnesses describe a generic white man with differing hair and yet again none have identified Brueckner or he would have been charged. He used his phone near PDL...yet again not a suspicious act. Not sure what you mean by your last point.
In my opinion, Wolter hasn’t enough evidence even to question Brueckner never mind charge him and I doubt that reality will change.
You really don't know what evidence Hans Christian Wolters has and I think you may be unpleasantly surprised if although I rather think it will be when he decides to press forward with it.
Not forgetting that a great deal of information has come in which all has to be processed which takes time. I think his priority is to find Madeleine whichever 50% category she falls into bearing in mind that without evidence to the contrary Wolters concedes she may still be alive.
In my opinion the only people who have a stake in moving the investigation forward is the McCann family for whom this must be Hell on earth. We are dabblers and dilettantes in other peoples' lives so it really isn't life changing for us as it is for them.
Brueckner is going nowhere for some time yet.
Therefore there is all the time in the world for the Germans to take their time and conduct their case appropriately; and I don't think they are about to be rushed into premature decisions until they are good and ready to proceed.
I think Madeleine and her family deserve that amount of respect.
