These ridiculously farfetched sighting's are becoming sad now. So this person, who clearly knows that Liam is missing based on the fact he reported it, see's somebody matching Liam's description holding a sign saying "help get me home". They don't talk to the person or report it to the staff at the train station, they then just report it to the police, seemingly later on? And no one else picks up on the fact that an out of place man is standing there in a small village outside a train station holding a homemade sign written in English? And Liam, who based on this news story is clearly aware that he is missing, instead of going to the authorities, or even just telling the staff at the train station, stands there holding a sign hoping for a hitchhiker to pick him up, at a train station?!
Like rehtnap said, we really shouldn't put much credence in this type of press. It hurts to see that there's a new sighting and then having to read rubbish like that.
