No, you're quite wrong. I know, by Wolters admission, that they have no DNA or forensics.
The 'evidence' against CB is limited to a number of possibilities, which I have previously listed on the evidence against CB thread. The best example of possible evidence suggested by your compatriots was CB's confession to Busching.
Due process has already happened, Wolters has nothing of genuine substance against CB, hence the reason he still hasn't been charged, & won't be getting charged with anything related to Maddie, any time in the forseeable future. That's how concrete the concrete evidence against him is.
Who mentioned "concrete" evidence apart from you and other sceptic bloggers.
As far as I can see concerning the foreseeable future - that belongs to the victims of three aggravated rapes, the child of the German family he subjected to sexual assault on the beach when he laid hands on her and the children he traumatised in the playground - all of which crimes for which he will answer charges to when his legal team has sorted out their procedural objections.
In the interim according to Wikiprdia - festina lente. (Latin: a classical adage and oxymoron meaning "make haste slowly" sometimes rendered in English as "more haste, less speed") the meaning of the phrase is that activities should be performed with a proper balance of urgency and diligence. If tasks are rushed too quickly then mistakes are made and good long-term results are not achieved.
