mayb cuz BKK is pretty infamous for missing persons.
My colleague's neighbour went to BKK for honeymoon and lost his
wife there. They both got into a tuktuk and the hubby realised he
forgot something. Left his wife in the tuktuk to go back to the
hotel room and when he's down, both the tuktuk and his wife were
gone. That's the last time he saw his wife. Poor chap.
Have heard similar stories before but they were all hearsay..
untill the above incident.
