The deponent remembers that upon reaching the top of the stairs, she looked to her left and saw a man (1) with a female child (2) in his arms, walking along the pavement of Rua 25 de Abril. He was walking in her direction at a distance of, give or take, two metres. (AS)
So Smithman crossed the road to the opposite pavement and was going down when Aoife got to the top of the stairs. So he passed behind her as she started crossing the road. I'm surprised SY haven't got the Smiths back to do a thorough reconstruction. I would do it.
Your second paragraph is not certain, pathfinder. We dont KNOW that he crossed the road.
We certainly dont know whether he went down the steps, or whether he carried on in an easterly direction down Rua 25 Abril. As John says that is in the direction of Sergies.
In fact if the photo previously shown, (by ?Mr Mod) is correct then Sergies flat was just behind the Chinese Restaurant, This is only the second building along and a distance along Rua 25 Abril of just over 30 metres from Aoifes sighting.
I must admit that I thought that Sergies flat was behind the real estate agents, which is the next building along Rua 25 Abril after the drive in gap ... and some 45 metres east from Aoifes sighting.
But I am happy to be proved wrong. As far as I can see there are only three commercial premises along there. Maybe there was a fourth in the gap after the empty shop [on the current GE street scene]
Needless to say, we truly do not know whether Smithman went down the steps or east towards Sergies. 50/50
From Aoifes statemebnt we know he didn't go west tho.
Anyway, I dont want to speculate. It is kind of ex judice.
