I think he's going to "play dumb", and just stonewall away and repeat he hopes to be exonerated, with a "golly gosh geewhilikers, folks, I don't know what you're talking about, I don't know how my DNA got there, I don't remember a thing about that night", and leave it to his defense team to duke it out with LE and the prosecutors. If a "frameup" does come to mind for his defense, or a case of DNA mixup or whatever that allows him some wiggle room, I'm sure he would probably shrug his shoulders and say, "yeah, it has to be something like that, because... I hope to be exonerated". MOO
