How can you say the window wasn't open when Matt did his check 30 minutes later?
Matt says this in his statement -
Consequently, he is convinced that at the time of the second check the blinds were more open than on the first check, given that he considers that the light inside the bedroom, undoubtedly coming from the outside, could not have been coming through it [the blinds] if they had been fully closed.
The window could have been open.
That was the first time in the flat for Matt. There were slats open that explains the streetlight next to the car park entrance shining in.
The outside blinds were closed with only two or three slats open.
http://www.mccannpjfiles.co.uk/PJ/GERRY-MCCANN-10MAY.htmMatt didn't see curtains moving or feel any draught so no window was open at 9:30. No abductor before 9:30 explains the open window.
"I was there to check, erm, no, no funny sort of smells, no sort of funny draughts, no sort of funny sort of noises, no, erm, nothing that I can think of for that. I mean, it was a complete just a shock out of the blue when, you know, I'd been in and then suddenly somebody's saying Madeleine's missing, there was nothing that made me think, oh'."
