My theory is just that, a theory. I think he was caught because of 2 things. 1. he was flagged for bringing in tons of chemicals from outside the country 2. he was snitched on. He did have over 120k on him, yet he had to get a public defender. (that was from the news article about his arrest). A guy with his volume needs to have a good chunk of money put a way in a safe place for a kick ass attorney/bond. If they found that amount in his possession, you would have to think that he has done millions in business. so one would have to conclude that he was a bad business man, etc. He use only one post office (apparently). He did many many things wrong.
