in the last episode jane plays a game with the police officer who got caught as tyger tyger member..
jane said he asks him questions and he has to answer it with his mimic etc.

so jane asked him if reede smith is red john, but he knew its not true cause of his face mimic
then he asked if it's gale bertram and he saw again in his mimic its not true..

so jane was sure its one of the "dead suspects" but he didn't tell anyone cause he wants to catch red john himself and cause he wants red john make think that he really dont knows it so red john doesn't pay attention cause he thinks jane dont knows..but im sure red john is smart enough to know that jane knows its not gale bertram..

i think red john is brett partridge, since they showed us mcallister in the promo it would be too obvious if he's red john..

they said mcallister died but i think mcallister had the bomb under his hat that he left on the couch so bret stiles and ray haffner died..cause mcallister was the only one who knew about the bomb he prepared to escape from jane's house..but that does not mean that mcallister is red john! maybe mcallister was with red john in the car that we saw when lisbon arrived to janes house..

sorry for my bad english, i hope you know what im talking about

Anybody else find it interesting that McAllister, Smith and Bertram were standing right next to each other during the blast, and yet Smith and Bertram are alive and McAllister was confirmed "dead"? Exactly how did the bomb kill Haffner and Stiles, who were on the other side of the room AND McAllister, while Bertram, Smith and Jane are unharmed?  Anyone care to explain the physics of that? I sure can't!  There is no way McAllister could be dead.  

More importantly, how can we assume that ANY of the suspects actually died?  The Blake Association has people everywhere, probably in forensics, given that Partridge was most likely a member.  Who confirmed Haffner, Stiles and McAllister to be dead? Forensics!  Why on earth should we trust their word?  For all we know, NOBODY was killed and they're all in on it somehow!

We thought things were narrowed down, but lots of Tiger, Tiger people in Forensics opens up a huge can of worms.  How can we trust that anyone is dead at this point?  We can't even be sure of Partridge or Kirkland!  My money is still on McAllister, but I'm starting to think it's anyone's game!

Uh... Im really tired of Partridge's theories... I know he would be a great Red John, I thought he was Red John till the beginning of season 6 and then I started looking at facts, reading interviews and putting things together.

OK Jack Plotnick (Partridge's actor) said that he was playing Partridge as he was Red John the whole time. That's why everyone is so convinced that its him.

Its a trick that Heller played to us so everyone will believe its him till season 6, and yes he has too many fans that still stick to him.

Additionally, the actor that plays Red John said he was stunned and fluttered when he learned that he will play Red John, which ofc doesn't fit with Plotnick who was playing Partridge like he was Red John.

I try to minimize the people that write Partridge theories because its getting annoying, Partridge is not Red John please choose someone else and stick with him otherwise you will be really disappointing.  

Please read his interview here: http://www.tvequals.com/2013/09/23/exclusive-interview-the-mentalists-jack-plotnick-talks-playing-brett-partridge-being-a-red-john-suspect-flies/

I wanted to note that Red John didn't just killed Partridge but he also hit him, he had bruises on his faces which is a little bit weird. For me it indicates that he did something wrong and Red John punished him. Best thing i can guess is that he gave away himself as not being Red John and reducing Jane's list to 6 suspects when Patrick looked him in the eye.
Sorry if my post disappointed you,,, but please dont trick yourself, open your eyes, do not just see what you wanna see otherwise you will be blind to the truth.
