It doesn't sound like a racial beating to me..with no commotion, no signs of a struggle etc. I would get the FBI involved. It almost sounds like a Shanghai but hopefully we are in the wrong century for that...but if he was taken against his will he would have had to have been doped and taken out through a window or something..have you checked out the window and exit situation there? Of course he could have been threatened and asked to go quietly or they would hurt family or something. Hate to get this way but no stone must be left unturned. Is he from this country? Could he have unsavory connections,involuntary? Could he have been lured to this particular bar? COuld there be old trap doors etc. from previous times?

Of course it could have been totally voluntary and not great reasons, such as another woman, escaping debts, etc., but at least he would be safe if that were the case. mg
