There was mention of his name in the responses to the 2013 showing of Crimewatch in Germany, but I don't think anyone was named as coming forward with information?
There was mention of his name in response to the abortive attempt to locate him in 2007. Nor was there any mention of trying to check out home invasion crimes. In particular the molestation of children in their beds and the horrific rape of DM in her home in very close proximity to the McCann apartment.
SnipAmaral, 60, said: “I have been told by colleagues, who are retired like me, that they had come knocking on the door. That person was not at home.”
He said he was not aware if any more inquiries were made after the visit, which was made shortly after Madeleine vanished in Praia da Luz, aged three.
Amaral’s comments, in a TV interview on Portugal’s TVI, came after it emerged last week Brueckner told a judge he was a paedophile when he was in court in 2006, charged with petrol theft.
But officials in Portimao apparently failed to pass that on to the Policia Judiciaria – which Amaral was in charge of.
Lisbon-based Amaral said on TVI that police did not know Brueckner, 43, was a convicted paedophile.

all the available information including the Praia da Luz rape two years previously and a couple of minutes distance away but who didn't co-ordinate it.
