Maybe the dead guy knew too much.

Yeah, following his little flashback, I thought Cambodian was a possibility too. I'd expect him to be a product of a location full of strife and bloodshed; some of these options (like Afghanistan, but it's a huge coincidence) fit the bill, I'd say, although he could have been born anywhere and picked up the habit of killing along the way.
As for nationality, I've always seen Gauron as a "citizen of the world", so it didn't matter much. I doubt any country would be proud to have him anyway.
