The Tannerman sketch shows someone with longish black hair combed to one side, can we be sure it wasn't a women JT saw?
As for the time-line, some believe that the abductor had already entered the apartment and was hiding when Gerry made his check of Maddie.
The only thing is, why would the abductor risk raising the noisy shutters and risk drawing attention to the apartment? Of course they probably thought that Gerry had went straight back to the bar?
Of course this is assuming that Tannerman was the abductor, which does kind of fit with Matt Oldfields statement where he says the kids bedroom seemed to be lighted up from an outside source!
Dr Totman has said he thinks the man JT saw, so-called Tannerman, was in fact himself because the artist's impression by way of physical appearance and clothes worn matched. What more do you want? What are the chances of MM's abductor sharing the same physicality and clothes? Has Dr Totman ever confirmed the direction he was walking in? If he was walking in the opposite direction to the direction JT believes she saw, she may have suffered a false memory. She would have been in a state of shock learning MM had gone missing, the shutters open etc and put 2 and 2 together and got 5! She didn't think at the time 'hey that's someone abducting MM' because had she have done she would have done something about it then and there. She is only thinking it was potentially MM's abductor after the event. The simplest answers are often the correct ones.
We cannot be certain GM actually observed MM. I know he said he did. But initially he said in his WS he entered via the front door (locked) and not the unlocked patio door. Probably because he felt a range of emotions at how stupid his decision was to leave his 3 children under the age of 4, completely unsupervised, in an unlocked holiday apartment. I would say the normal range of emotions would be overwhelming embarrassment, guilt and shame. If he didn't actually observe MM this means she could have been abducted from approx 8.30pm to 10.00pm.
How likely is it the abductor was in the apartment when GM did his check? Not very imo.
It was the first time MO had physically checked inside 5A and looked inside the bedroom so he had nothing to compare with in terms of how dark/light the inside of the room normally appeared. He said there was no draught and/or flapping of the curtains.
How do you know the lifting of the shutter was noisy?
Here's an image of CAT. I think we can safely say CAT and Tannerman are not one and the same.
