I have gone through everything I can think of in my head and still cannot come up with anything definite. But I am still sure that this had to be a targeted abduction.
No one would have broken into 5A at that time of night without first watching the occupants, so must have known that there were three sleeping children inside without a parent for at least half an hour at a time.
So I am still where I have always been. I still don't know who.
At the moment we can only speculate on precisely who the perpetrator of this crime may be. But it having taken from 2013 to 2020 to reach the stage we have today with the German prosecutor turning up a creature like Brueckner who I would say ticks all the requisite boxes, I think it possible he is a worthy suspect.
In my opinion he fits the profile.
Who knows though ~ there might be more than one ~ or two or a whole gang of them; but it was Brueckner's phone which pinged just as did Silva's, Ribeiro's and Rodrigues's who were questioned in 2014.
They were questioned and cleared which might happen when eventually the Germans get round to questioning Brueckner; but I wouldn't bet on it.
