I find Michael Kirkland as likely..... but there's just one thing that doesn't add up, Bob Kirkland clearly told Jane that his brother MET red john and changed because of it, so it kind of rules him out...unless it's like in star wars where obi tells luke that his father supposedly "died" but what he meant was that he had undergone a transformation, Anakin->vader, Michael Kirkland->Red John..hehe
