He may have taken a detour for whatever reason.
Do you think it likely that a father carrying a sleeping child on a cool blustery evening would make a detour?
Children, even young children, get heavy after a while
He wasn't coming from the OC creche. There is nothing up that road, Rua d'Escola, really except for the Staff Quarters ... and further on the Estrelas appartment bloc ... then further on still block 5 Ocean Club and Madeleines bedroom.
The whole length of Rua d'Escola, on its Eastern side past the Smiths, is fenced in waste land or a bit of car park. Fenced in shaley, hilly waste land and dangerous to walk on, I found.
The route that he appears to have taken is very quiet and as it bends in an eastern direction, (directly towards OC blocks 4 and 5), there is also a school whose playground takes up a portion of the northern part of the road.
There's nobody likely at 10pm at the school and just a house or maybe two en route. Very very quiet route except for maybe the apartment Estrelas and The Staff Quarters.
Personally I think that he had a room, or a friend (accomplis?) at the Staff Quarters and that he called in there after his pick up vehicle let him down, and he had to walk. According to the forum, The 3A's, a scream was heard coming from there. A long sleeved top could have been picked up there too. Dunno
These are just thoughts and may have no substance, but then again may.
They explain some anomolies in the case, such as the time gap between Janes sighting and The Smiths sighting and the long sleeves.
