Why should it? Only Kate McCann's fingerprints were found on the children's bedroom window which tends to support the proposition that it was she who opened it to look for a missing Madeleine. She claims she found it open but that could be down to traumatic memory loss, the same affliction suffered by Gerry that night.
No … it happened exactly as Kate McCann described and it is borne out by the evidence that the window was already open when she entered the room. There were no fingerprints lifted from the handle.
VESTIGES COLLECTED5….. Fingerprints….Inside interior window of the children’s bedroom…..DBT…..Suf
Observations: The fingerprint traces collected are identified as being the middle finger of the left hand (3x) and forefinger of the left hand (2x), of the missing girl’s mother,
http://www.mccannpjfiles.co.uk/PJ/FINGERPRINTS.htmThe right hand sliding glass was open.
A person leaning forward to look through would support themselves using their right hand either on the wall or the windowsill. While placing the palm of their left hand on the frame of the already opened sliding section with fingers extending onto the glass to leave fingerprints.
That matches the description of events given by Kate McCann from which she has never wavered. It matches the forensic evidence as recorded in the PJ Files above. There is no forensic evidence that she opened the window, but the forensic evidence supports her statement that she found the window open and she leaned out.
