It looks like Brueckner is exonerated regardless. He is free. The McCann's would be going berserk about Brueckner being free, if they believed he abducted, raped and killed their daughter.
Not a scintilla of evidence exists linking CB with the disappearance of MM. When the story first broke, around mid 2019, I was posting on Red and said straightaway it would not go anywhere.
To understand the case it is necessary to consider the way in which the security to 5A, by way of doors and windows, was left each and every night along with the repetitive nightly habits of McCanns and T7. You then realise this was not a random person happening on 5A but someone who was completely aware of the lack of security, accessible children and window of opportunity. This narrows it down to 3 people: Mrs Fenn, Christopher and Carole Tranmer. Afaik Christopher Tranmer has never even been interviewed by any police force despite the fact it is known he was only meters away from MM around the time she went missing.

During the McCanns visit to Portugal she and her husband visited around the same time, staying about an hours drive away, and visited Ocean Club to visit Carole Tranmer's aunt, Mrs Fenn, who was the only owner occupier at Ocean Club. Her apartment was directly above 5A.
