Dean Harken looks interesting as Red John. A meticulous and highly intelligent man with a god complex and a job that puts him in a great "push-button place" of power with incredibly deadly pathogens under his control. He appears in the episode Code Red. the name Dean means "law" among other things. Harken means "listen", and the surname is of Irish origin. Dean Harken has red hair and is most obviously irish. Roy is another name used by Red John and is also of Irish origin. He Is just under 6'0''. Moreover, Dean Harken is on Jane's list of suspects and if you watch closely his eyes seem to focus on the name before he gives a contemplative expression in the episode "Red Cherry". Any takers...?
