I think the list is not fake, in the preview we see the 5 suspects all together. so what does this say..
that the list is right. one of them is red john, heller also said it himself.
so dont post theories that Bob Kirkland, Brett Partridge, Patrick Jane is red john because that is just foolish.
My money is on McAllister, i dont know exactly why but...
 - Reede Smith, to fat, and he is part of the Tyger Tyger group if their is a group. also can be a distraction. but he is not red john.
 - Bret Stiles, he is old and why would he feel the need to be a serial killer, he is smart enough but he is the leader of visualize. that is everything for him everything he has fought for so hard. If patrick discover him as red john he wil lose everyting.
 - Gale Bertram, leader of CBI, possibility, a logical suspect for red john but he is a bad poker player, so he is a great actor and manipulater or just not red john, i go for the last one. he is not stupid but i think not smart enough.
 - Ray Haffner, he was my number 2, but my reason that he is not red john is that he once allready fel for a trick of PJ when he was his boss and if he was red john that would be a perfect possition i think so why give up on it, because he is not red john. 
if McAllister is not red john i give Haffner a good chance

so my conclusion is Thomas McAllister

tnx for reading am a great fan of the show and i really looking forward to the Red John episode

(sorry for the bad english)

Does anyone remember the episode where they show RJ holding a cup of tea with his left hand? If you zoom in on his hand you can clearly see what looks like a wedding ring.

Only two of the suspects wear a wedding ring: Gale and Tom.
Though Bertram doesn't strike me as a killer type persona, I'm still suspicious about him.

Thomas was just down right creepy when he started hitting on Van Pelt and when the blond lady from the 6x03 episode walked by him, he looked at her with this strange grimace on his face. I don't know if it's just me, but whenever I see the sheriff, I just get the impression he's having the time of his life playing a dumb cup wearing a dumber costume.

Synopsys of 6x08 (Red John) :

Patrick Jane finally comes face-to-face with Red John, the serial killer he's tracked since the man murdered his wife and daughter . For 10 years, Jane has droggededly hunted his nemesis in his search for justice.

So... we'll finally know. Just 3 weekends. 

From the beginning i always thought Red John could be Brett Partridge, because of his voice and skills, etc. But now that he is dead (confirmed by Heller and Plotnick), i guess Red John could possibly be McAllister, im just still curious about Kirkland's Brother, after all Bob Kirkland's voice is very alike RJ's voice on the phone. 

Truth is, none of us have the ideia of who could be RJ right now, Heller finally confused everyone hahahahahaha... 

Sorry if i type anything wrong, im from South America. 

In my previous post I stated that I believe Haffner or McAllister are Red John and I went with Haffner. But now I have to adjust that to McAllister. So here is my summary again:

http://www.whoisredjohn.com/See-a-theory-Red-John/5451

So yes, I now firmly believe McAllister is Red John. Same reasoning as stated above.
Have a nice Day :)

The moment they showed us Haffner's fear of spiders, I concluded that Sheriff Thomas McAllister is the bloody killer. It's so obvious at this point that Haffner is just a big fat red herring. Why would RJ risk being exposed as a visualize member? Why would he deliberately talk about his phobia issues to someone involved in the case (Lisbon)?  RJ is smarter than that.

In 6x03, as McAllister leaves the cliff/hill/view thing whistling. Sophie Miller made it a point that the person she interviewed was a good whistler.

Coincidence?

In regards to the new interview where Robin Tunney was surprised at who Red John is, read her statement from May re: The List of 7.

From: http://redblog-thementalist.blogspot.com/2013/05/spoiler-exclusive-mentalist-postmortem.html?m=1

"When you learned where the finale was going, were you surprised that Jane and Lisbon would be this close to catching Red John?
Robin Tunney: I was really surprised. I was also really shocked at some of the names on the list! They weren't revealed to me until we shot the scene. I assumed Bret Stiles and Michael Gaston's character would be on the list. But Xander Berkeley, who was in our second episode and Jack Plotnick — I was pretty shocked. It'll make for a really exciting sixth season."
