patridge, kirkland are dead. smith works for red john in the tyger tyger organization. so does bertram and mcallister. bret stiles is too famous, i believe, for red john to work with that level of discretion, he would need to be a face in the crowd, someone who you could look at and wouldn't remember. since mcallister and bertram were meeting when Jane interrupted them, and bertram was asked how much jane knew, i think that mcallister and bertram are definitely working for red john. this leaves Haffner. haffner does not stand out too much, seems kind hearted, and according to jane's (and red john's) therapist, red john is a man who conceals his intentions very well, since she said she could sense something dark underneath him. haffner seems capable of that, so i believe it'll be haffner.
