So why no forensic evidence on the window or sill?
Indeed that is the first question anyone would ask - including the police. It's for that reason that I believe Kate McCann when she said she returned to find her daughter gone and the shutters and window wide open. And as any normal person would think imo - she
assumed, at that very first moment, that someone had broken in via that window and taken her child. She had no way of knowing at that time that no forenics would be found to prove that.
If, as some people claim, she was lying as part of a pre-conceived plan to claim the window/shutters were found to be open - as proof of an abduction, then surely the McCanns would have made damn sure that some damage was done to the shutters and maybe a few scuff marks were made on the cills. And they would have certainly made sure no fingerprints of theirs were left on the window.
IMO we are being asked to believe that the McCanns were so stupid that it did not occur to either of them that if you are going to claim a forced entry - and this is what you are going to hold up as your evidence that a stranger had been in the apartment - then there would need to be some evidence to prove a forced entry had actually occurred.
I do not believe the McCanns were both so idiotically stupid that they would have overlooked that very obvious fact.
It
was the McCanns first belief that a stranger had broken into Madeleine's bedroom via the window and abducted her, but as time went on they realised that it was not the only possible scenario.
