It definitely has to be him. The young guy who will play Red john of 1988, resembles Thomas Mcallister. The age also matches. The guy looks around 20, and Mcallister according to the script is 45. It would be disappointing for everyone if he turns out to be Red john as he just plays the role of a normal Sheriff. The boots he wear, also tell the same story. Moreover, when Rebecca was killed, he was there. Good posture, middle aged man, excellent whistler and has no family of his own. Jane also said he is not dumb as he looks. He was in the series since the beginning, so I suspect him
