I don't know Portugual at all, but if this was just another Dad, where might this man have been going with his child?
If a holiday maker could records be checked to see if any one was renting down that area? Police seem to think he was on his way to the beach area, where on the beach area could he have been staying, have they checked?
If he was another dad returning from somewhere with his child, not only where was he going but also where did he come from is of interst.
And as the father of a little girl the same sort of age as Madeleine, why hasn't he come forward ? ... any father would feel for Madeleine, especially if he had a daughter of the same age, and he knew the talk was about him and his daughter. I cant believe that such a man would not come forward.
Mainly because of this , I cant help thinking that Smithman was carrying Madeleine and that is why he hasn't come forward. Crechman came forward it seems, so why hasn't Smithman?
