He also rebutted claims made by disgraced former police officer Goncalo Amaral, who met with Brueckner's defence lawyer Friedrich Fulscher last week in Portugal, that the German was being 'scapegoated.'
The controversial ex-cop, who was removed from the initial Madeleine McCann investigation for criticising British police, is involved in an ongoing legal battle with her parents Kate and Gerry over his insistence she died by accident in their apartment and they covered it up.
He told the RTP channel's Sexta as 9 show: 'I know this former inspector speaks a lot and comments on our work.
'We're not going to get into a war of words. All I will say is that we have carried out a very serious investigation and there is no indication whatsoever Madeleine McCann's parents are linked to her disappearance.
'On the other hand we have a lot of evidence pointing to Christian B killing her.
'Goncalo Amaral knows how he reaches his conclusions and that's not up to us to judge.'
