I believe that the front door was used, both in and out, and the window was an escape route.
There is a flaw in your argument, Kizzy.
If he needed a quick exit and didn't want to seen, then as soon as anyone checking came to the patio door. then if he were as agile as CB obviously is, he would be better going thru the window, To go out through the front door, he would have to come out of the children's bedroom into the living room and potentially come face to face with whoever was checking.. And the checker would certainly see him exiting via the front door, and chase after him.
I wouldn't fancy his chances against Gerry
CB is obvious extremely agile, but the window would not be such a good escape route for your average man
If he needed a quick exit and didn't want to seen,I cant see the logic of opening the bedroom window if CB needed a quick exit. [time wasting and noise]
Surely the quickest exit would have been the front door - in and out in minute/seconds.
Strange too that kmcc although spent 10 mins searching the apartment did not look out the front door.
Also letting twenty-odd people into the search when she knew Maddie was not in there and if abducted there could be evidence.
Hopefully, Friedrich Fulschner will be well aware of what proof there was for an abduction etc.
Although deathly quiet on everything now it could mean as expected the investigation is going to be dropped.
What else can you expect with witnesses like this?
The lawyer for the prime suspect in the Madeleine McCann case Christian Brueckner has said that he does not believe the German will ever be charged in the case.
Friedrich Fulscher has said that the main witness against Brueckner, 43, is a criminal who swapped information for police favours.
