9. He might have been ‘Smithman’. The Smiths saw someone, also carrying a child, at 10.00pm. It could well have been the abductor (Tannerman) still carrying his child around Praia da Luz.
No abductor was carrying a child around Luz for 45 minutes. To believe that happened is complete madness. They were heading in different directions. One had long hair, one short. I don't have to explain any further the absurdity of such a claim.
As I have explained earlier, it is possible especially with a break somewhere. The Staff quarters being a few yards up the same road as the Smiths sighting immediately comes to mind.
As for the different directions.
Tannerman was walking towards a rendezvous with the getaway vehicle and in an emergency situatioon kept on walking. Smithman, who could easily be Tannerman was purposely striding it out to what seems was a definite destination. Someone had told poor lost Tannerman where to go. I think that the accomplice at the Staff quarters priobably phoned around for him and relayed instructions. It all fits, but I know that I could be wrong.
Can you come up with a better solution?
