Sorry if it wasn't clear, I meant his addresses being visible on both the input and output of a mixing process but being discovered via separate means, one via tracing where the codes were sold, one via tracing his bank activity after investigating which account generated the codes.
It certainly could be enough to connect him, if they already know the fraudulent codes were generated from his account, and you can see the mixing process and that he was clearly an output of it, that means that he would have had to buy bitcoin from someone who used his account to generate those codes... that's not going to play well to any judge or jury.
