I am Norwegian and I have also lived in Chiang Mai, but that is the only thing we have in common. They managed to spell his last name wrong , so I had to check if he really is Norwegian and sadly he is.
If he is guilty, now it is still a big if, I understand he confessed but you never know what have happened , there could be language problems here etc.
All I know is that the Norwegian embassy already been contacted and he will get some good people to help him there .
As you would expect this is headline news in the Norwegian media, if he is guilty of murder I do not feel sorry for him, but it could have been self defence.
