Tannerman (abductor, if Brueckner) headed towards where one of his vehicles, Jaguar or Westfalia camper, was parked, in the triangular area between Block 6 and the block to the right, say? Then off to his yellow and white hidey-hole cottage up on the foothills of the Rocha Negra. Or possibly walked there, although he and his arms would have been mightily tired by then. Strange way to carry a sleeping child (dead-weight) for a long or even a short distance though, whereas the normal over-the-shoulder position (like Smithman) would be expected if he was a genuine father used to carrying his own three/four-year old.
Joining up with such a vehicle might have been his intention, if Tannerman were Bruckner, but the route he took did not go in that direction as you well know. Seems to me that a vehicle was meant to drive up to the car park entrance of block 5, but Gerry and Jez and Jane got in the way. This altered plans and the car driver took fright seeing Jerry that he shot off with the car in a southerly direction.
Just muddying the water again aren't you? Trying to spread confusion it seems to me.
Oh dear! How people can try to confuse with a little girl missing is beyond comprehension to me. SY will have worked it out anywy.
