Given he's been on the radar for 4 years and no charges relating to MM, i do still believe he's part of a bigger thing.
I still think that the german police are strategically (and have been) releasing tid bits to flush out others within his circle of acquaintances for information, observation or implication and have been trading information for leniency and as a result, MM is not the current focus.
Her disappearance of course is the investigative line but the path can deviate and there hasnt yet been any charges except for those designed to keep him in the jurisdiction.
The police may decide to charge him with multiple cases of child abuse or rape etc etc, which could put him in prison for a long time - even as many as he wouldve received if convicted of MM.
what i dont get is how a prisoner can access 1 to 3 lawyers when they havent had any charge. And if he is allowed a lawyer, wouldnt that only be allowed to be for representation on current matters and not of matters that may or may not materialise
