Gerald McCann made an initial statement on 4th May and a more detailed one on 10th May. His later statement includes two interesting details;
That, between Monday and Wednesday, not knowing the precise date, when they left the residence by the main door, to place the children in the respective creches, MADELEINE left [went] running to the left to the extreme opposite of the residential blocks where they were lodged, playing with the twins. That they had gone down to the furthest point away from those blocks, not knowing exactly how, the three children got into the gardens at the rear [of the blocks]. Then they followed the inside corridor [pathway] at the rear, next to the hedges [fences] up to the street that led to the secondary reception.
After going through the side gate, and while on his way to the secondary reception entrance, less than 10 metres from the gate, he saw JEZ coming up the street on the opposite pavement bring with him a baby carriage with his youngest child. He crossed the road in JEZ's direction who would come up on the right-hand side [when viewed] from the ascending direction, both having chatted for 3 to 4 minutes, about tennis, holidays and children.
http://www.mccannpjfiles.co.uk/PJ/GERRY-MCCANN-10MAY.htmThe comment about Madeleine and the twins running away and going along the pathway between the apartments and the Tapas enclosure was probably his answer when asked why he thought the sniffer dogs both went that way when tracking Madeleine's scent. Without Gerald's explanation there was no reason for the dogs to go that way. They should have come out of the front door of G5A and turned right, tracking the person seen by Jane Tanner. Thanks to DCI Redwood, of course, we now 'know' that the person seen by Jane wasn't carrying Madeleine, so the dogs would have no reason to track him. It's possible therefore that the dogs were right and the trail they followed was the correct one. Unfortunately Gerald's explanation supported the Tanner sighting and the other route was ignored.
The other strange thing is Gerald's insistence that he crossed the road to speak to Jeremy Wilkins, although Jeremy and Jane Tanner were quite sure that he was next to the entrance to the path. He was so insistent that he made Jane cry during their reconstruction. Why was it so important, I wonder, that he stuck to his version and refused to accept that of the other two? It shouldn't have mattered where they spoke, what difference could it make? Why not just accept that he could have been mistaken? I can only assume that it was important to him.
My conclusion is that Gerald McCann didn't want either himself or his daughter to be associated with that pathway on the evening of 3rd May.
