I always though he was one of the more obvious dopers in the sport.
His training partner was Steve Mullings.
But once Tyson had one positive test, he pretty much had to admit to doping at London.
The Olympics is one of the few events where they freeze the test samples and can test for about 8-10 years after the games. Once there was a positive test for Tyson, you can bet they would have been targeting those samples each time they had a new improved test available.
