According to the Olive Press half a fingerprint belonging to Brueckner has been in the possession of German police since 2017. It connects him to the rape of an Irish woman in 2004. It was uploaded 'to a computer', apparently.

I wonder if the PJ treated this half a fingerprint as they treated the ones found in 5A? In that case they were passed to all Interpol Offices which found no matches in their databases. Interestingly, Wiesbaden was mentioned. They said there was no match at the time (2007). The BKA is involved in these checks. It's also involved in EWA's. I wonder if it held and used fingerprints to identify those it wanted arresting? If so, it didn't match Brueckner's fingerprints to that sample in 2004.

When Brueckner emerged as the prime suspect in Madeleine's disappearance, detectives took another look at the attack on Ms Behan to find out if he was the assailant, the Portuguese newspaper Jornal de Noticas reported.
However, they came to the conclusion that he was not responsible and ruled him out as a suspect, the report added.
The newspaper reported: “Jornal de Noticias has learnt that the idea it was Brueckner was considered when he became a suspect in the Maddie case.
“Unsolved crimes, like those of Hazel’s, were revisited and the investigators concluded he was not the author.”
Police revisited a number of unsolved crimes to see if Brueckner might have been responsible, the newspaper said.

The evidence trail will surely be most revealing when we eventually find out exactly what it is. Unless you are already in prior knowledge and can let us know now.
