I dont think that Tannerman ever intended to walk around PdL with Madeleine in his arms. He expected to be picked up by a get away vehicle parked in the little parking area opposite the Tapas Reception. He probably waited a short time in the dark areas of the fronmt car park ready to be picked up at the entrance to block 5 car park
I think the driver of the vehicle left the car park intent on picking Tannerman and Madeleine up, but saw Gerry talking to Jez in the way so dallied ... and then saw Jane witness Tannerman with Madeleine.
I think that Tannerman, with Madeleine in his arms, was fraught with anxiety at the delay, so was walking to the corner to see what had happened to the get away vehicle .... when Jane suddenly appeared. He made a rapid decision to walk across the road and quickly disappear from her vision.
On seeing this, the get away driver took fright and drove off in the opposite direction (south).
So leaving Tannerman in the lurch ... holding the baby, so to speak.
You're overlooking the (vital) incorrect translation in the statement of the s&r dog handler
http://www.mccannpjfiles.co.uk/PJ/ANTONIO_SILVA.htm*snipped*
That after having given the sniffer dog the towel and next to the residence of the missing girl, more specifically, next to apartment block 5A and 5, the first sniffer dog headed toward the door of that apartment. Immediately afterward, he headed in the direction of block 4, returned around block 5, and came down a road that exists between this block and the leisure area (pools, restaurants, etc).
He turned right; in the direction of the aforementioned apartment and headed toward the main road. There, he crossed the street and next to the wall of block 6, turned right, and headed toward the contiguous parking area. More concretely, he headed next to a light post and sniffed the ground around that post. After this, he crossed the street again and headed toward the access zone to the restaurants and pool area, sniffing the door which was closed at that time. He again went to the parking zone, and at that point, lost the scent.
G-Unit picked up on this before. The translation actually says "turned left" - ie, in the direction of the aforementioned apartment and the main road.
