You thought that he went overseas to score some drugs?
Most folks that we catch with drugs did not travel overseas with he idea that they would get drugs to smuggle back into the US.
It's just happens while they are vacationing, they discover how easy it is to get the drugs and make a bad decision and think they can get some through customs.
This year alone, I've gone through the bags of 2 very popular movie personalities. It had nothing to do with who they were, but where they had traveled.
Anyone coming back from the Dominican Republic is going to get looked at and especially if they are not flying commercial.
