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
