It is par for the course that when an individual with a profile matching Brueckners are discovered to be walking among us that the police of every county and every country to which he had access share information and take a very close look at murders and disappearances fitting his modus operandi.
For example

It is standard procedure in most civilised countries ... and the press generally report what is going on unless perhaps the investigation is taking place in a police state.
I think it is known as 'the freedom of the press'.
It is disturbing for me to witness the defenders of this awful man leaping to his defence apparently because he has been associated with Madeleine McCann.
By law he ~ in very stark contrast to what has been suffered by Madeleine's parents for thirteen years ~ is entitled to the presumption of innocence by the same people who heap opprobrium and libels to deny the McCanns their rights under law ... very strange behaviour indeed.
But there you are then ... I think there is a strong case to be made for double standards in operation here. Sadly though, there are those who cannot recognise that.
