i have posted my thoughts before. There is only person that makes sense. Gale Bertram.
-it cannot be kirkland. He only appeared in season 5.
- partridge is the favorite one but he is not. We know that one suspect is going to die in season 6 and it can only be Partridge.
-Reede, seriously!
-the sheriff coukd be an accomplice nt RJ.
-Ray is not charismatic as RJ.
-stiles is not a killer. I understand why he is on the list.
Gale Bertram is the only one that would make a great red john. They have been working for him all this time.
