OK sorry for my long post but i would appreciate if you could take some time to read it, also if you like it hitting plausible would be so nice! :)This is what I'm gonna do in this theory, I'm going to eliminate all 6 suspects and then I'm gonna stick with the one that cannot be eliminated who is probably Red John.
Bret Stiles.Ok maybe one of the easiest to eliminate, I know some people like him as Red John but i don't think that's plausible. From episode 5x13 "The Red Barn" we know that Red John is born approximately between 1960-1972 which of course makes Bret Stiles too old to be Red John. Additionally Sophie Miller said that Red John has good health but we learn in 6x06 that Bret Stiles has cancer,
Redee Smith.Redee Smith's actor is born in 1976 which makes him about 4 years younger than he should be and he is also a little bit chumby. We have seen ourselves that Red John has a thinner profile and from a spoiler picture Redee propably gonna get executed by the tiger tiger organization in the next episodes. So I dont think Redee is Red John.
Robert Kirkland.Ok many people like him, I like him too but he cant possibly be Red John... neither him nor his twin brother. First of all Lorellai Martins couldn't possibly know that Jane shook hands with him. Jane and Kirkland meet and shake hands for the first time in the end of episode 5x07 and at the beginning of the 5x08 Jane takes Lorellai out of the jail and she has no communication with Red John untill he tells Patrick that he has met with him. So first of all Lorellai could't possibly know that Patrick and Kirkland have met. Secondly Lorellai dies at episode 5x16 and Red John has already recorded the video with Patrick's list (and please dont tell me she is not dead... Patrick checked her himself) BUT Kirkland steals Jane's list in episode 5x19... uh? Why would he do that if you was Red John and already knows the names? He did it for himself because he wants Red John for him as we also discover and my theory gets verified at episode 6x04 where we learn that Kirkland is after Red John indeed. Now his brother being Red John? I don;t think so... Michael found cure at Red John's hand... he found his savior. I'm sure that one of the 2 Kirklands will appear again but I can't be sure if it will be Michael or Bob, we can't be sure which of these 2 got shot dead at the end of the end of the episode of 6x04. So Robert Kirkland is not Red John.
Gale Bertram.Here is the thing with Bertram. First of all he doesn't fit Rosaldin's Description, but if you think that's way too thin to eliminate him then there is more. Gale Bertram is a public figure, he goes on the TV all the time and his name is well known to the public. We know that Red John met Sophie Miller personally, he had a reason to do it, and he met her with the name Jay Roth. Now imagine Gale Bertram going to Sophie Miller's name and telling her that his name is "Jay Roth." weird isn't it? Sophie may have seen in the TV "Gale Bertram director of the CBI" it's really wierd and i dont believe that someone marked but his name could possibly act undercover changing his name all the time as Red John does. I think that;s a pretty big clue that can allow me to eliminate him as Red John.
Brett Partridge. (Oh yeah! :P)Bruno Heller said that it was very important for Partridge to die at 6x01. Enigmatic right? My opinion is that Bruno really check mated us by that move. Partridge's death was not clear and we are not sure if he is dead or not. But I believe that his death was not clear enough so none can be possibly sure that if Partridge is dead or not. Every theory about Partridge being Red John has a big question "And what if Partridge is really dead?" and every Red John theory about anyone else has another big question "What if Partridge is not really dead?". We have lost the game. None can be 100% sure about Red John's ID. That's why i think that Partridge's death was not clear and not because he is not actually dead. I believe Partridge is truly out of the game. But who can now be sure? None.
So we have 2 suspects left: Raymond Haffner and Sheriff Thomas McAlister.Let me explain how we can eliminate the last suspect.Red John had to do something to get one step ahead, he had to do something so he can know Patrick's next move again, so what did he do? He made one on purpose sloppy move to bug CBI by paying an undercover agent to do his job and then he tried to kill her. BUT he left her half-dead and allowed her to see his tattoo on purpose so she can tell Jane about that, Now he is one step. Now he knows that Jane will gather all 5 remaining suspects and he will try to kill him by planting a bomb. But his plan goes wrong this time and Jane doesn't dies but only gets hurt. That's the reason I believe the actual Red John has the 3 dots tattoo, he decided to give Jane a lead, not something really important that would really give away his ID but something that would take him closer by eliminating some suspects and would allow him to kill Jane. But luckily Jane is fine :D
So guess what... only one of our 2 remaining suspects has the 3 dots...
Sheriff Thomas McAlister is Red John!!!
Thanks for taking the time to read my post i hope you enjoyed and as everyone else none can be 100% sure what happened to Bret Partridge but I gave you my explanation on that and that's the reason i think he is dead which leaves McAlister to be Red John!
