Hello, I know who Red John is, I will divide my proof into several sections:
* REMINDER: THE LIST OF 7 SUSPECTS IS FINAL AND RED JOHN IS ONE OF THEM!

1) Height
As Rosalind Harker said, RJ is under 6", so if we take the 7 suspects real height, based on imdb.com,
we can see that only Brett Stilles, Brett Partridge and Robert Kirkland are under 6" tall.
so we have the final 3 RJ suspects.
Bret Stilles is too old because as according to the visuallize episode, RJ must be around 40,
because he's first or first to be known murder was when he was around 25, and that happened 15
years ago (S5E13 if im not wrong).
Kirkland isn't Red John because Jason Lennon recognized RJ and Lorelei Martins but he didn't
recognize Bob Kirkland becuase BK killed him in his bed.

2) Age
A lot of people thinks that Brett Partridge is young, well maybe he looks that way, but according to
wikipedia, his age is actually 45 (almost 46, Born at: October 30, 1968).

3) Voice
This is a crucial evidence, the voices of RJ and Brett Partridge are almost, if not, identical.

4) Behavior, Hobbies and Basic Knowledge
Well, Brett Partridge is a sick twisted person, as you can see in the crime scenes, he has
absolutely no feelings, he admires RJ's work, and enjoy from the smiley printing on the wall, and
shows exactly how RJ committed his crimes.
So why did Brett Partridge thought that RJ committed the murder, while a copycat actually did it?
Think about it, if you were talking to Patrick Jane, and you know "heh im the killer, if he gets me im
finished", right? how will a smart manipulative serial killer will take everyone away from he's back?
Tell them information that "proves" he has no clue about RJ, which will lead Patrick Jane and the
others into thinking that he's just a twisted guy, nothing more than that.
Brett Partridge read poetry by "William Bake's", and in the ending of season 3, RJ says "tiger tiger",
which also derives from "William Bake's" poetry books.
Brett Partridge and RJ both know spanish, RJ is known to have friends that speak spanish, Brett
Partridge likes to talk in that language,
RJ and Brett Partridge also dislikes Patrick Jane, mainly because of his "medium" power, Brett
Partridge actually laughs and teases Patrick Jane, just like RJ does.

5) Connections
RJ has connections, no doubt about that, Brett Partridge alone can't have connections for as much
as we know, but:
Bob Kirkland and Brett Stilles have these connections.
Bob Kirkland is the hitman and the one who pullis the strings for RJ (Brett Partridge), while it is
unclear how they met, we know for sure that Bob Kirkland is the guy who does the dirty work for RJ.
Brett Stilles has a lot of power, but he can't be RJ for many many reasons, so why would he help
RJ?
Remember that Brett Stilles likes to help to visualize members, and RJ was a visualize member,
so Brett Stilles probably helps RJ, just like he helped Rey Haffner with his invest in a new
bussines.

if the first murder of rj was 25 years ago he is probable over 40 if we asume that rj start killing at a young age. 
i dont know if at any time they say but i dont think that brett partridge is old enough
then we know that rj was on visualize and that haffner is a member but i dont think that its relevant becouse anyone can be a member 

 We all remember when red jhon saved jean life ,then told him the famous poem  "Tyger! Tyger!burning bright.in the forest of the night." http://www.youtube.com/watch?v=ns_DWnqrEdIit seems to me that brett has the same voice and tall as Red jhon  3:) 

I keep reading all these far-fetched and honestly, quite ridiculous theories, and I think,"This is way to complicated! Think back to what Patrick always says! "The simplest answer is usually the correct one."" I honestly don't think Bruno would make it so complicated by making PJ or Lisbon Red John, Lorelei still being alive or more of this nonsense. People made it way to complicated by letting their imaginations loose or thinking of ways the story line could become "interesting." Anyway, lets get to it.


What so we know? We know that RJ is a shade less than 6'0, short, straight black hair and a soft voice. This is based on Rosalind's description in the season 1 finale. Logically, this would rule out Bret Stiles, because of his age and physique. However, even if I rule out a suspect as Red John, I most certainly will not rule them out as a disciple. Bertram is bald and 6'3. Reeder Smith is fat and his physical characteristics are not the same as Rosalind's description. Sherriff McAllister is taller and too unimportant and slightly older than RJ. His characteristics are not those of RJ's. Ray Haffener is 6'1, and even though many people might say that is almost six feet, he does not match the description and does not seem smart enough. Now we get to the last tow who are more believable. Robert Kirkland, a Homelqmd Security agent could very well be RJ. He is definetly a suspect after he murdered Jason. But, he is 5'9, and I'm sorry people, but I don't see him as RJ, even if he is a murderer and probably a disciple. Last but certainly not least, Brett Partridge. His voice. Listen to the voice of Red John from the season 2 or 4 finale, and compare it with RJ's. He could definetly modify it like that, IF he even modifies it. Next, he is 5'11. The exact height Rosalind Harker described. He is the forensics expert on RJ crimes, so he could tidy up after himself, and being with the CBI, he can keep on eye on Jane. I feel that he has a hidden side and he holds something back. He is definetly the serial killer maniac psychopath type of guy. He is more than he lets on. PJ and him naturally hate each other.

Even if I am against the nonsense of many theories, I won't deny there is something fishy about most of these suspects and they are on the list for a reason. For instance, maybe Stiles is the master mind, and he sends his assassins under one symbol to murder. Not saying that is what I think, just saying I won't rule it out.

Anyway, I trust the list and I am certain PJ is not RJ, nor is Lisbon.
Thanks for reading!

GUYS I KNOW WHO IT IS!!! I have proof!! Listen to this: http://www.youtube.com/watch?v=ns_DWnqrEdI starting at 1:18 LISTEN to the voice!!! I checked out all of the 7 suspects from the list and THIS is who it sounds the most like: http://www.youtube.com/watch?v=k26u5EOWWTU They both sound SUPER Similar but NO ONE NONE of the other suspects sound even CLOSE to red john! Plus he knows exacly how red john did this murder in the clip and seems impressed! He is a man JUST under 6 feet tall he has short straight hair all of these which are FACTS to what red john looks like! And he is over 30 years old!! This is him!! BRETT is Red john!! I assure you guys it is him!

Heller confirmed the list to be accurate. What he did not confirm was how many on the list were RJ. Of course nobody thought to ask him, because how would more than one RJ make sense? His seemingly personal grudge against Jane makes it seem like an individual. However there are obvious loose ends from season 5 which point to some amount of unity among them. Kirkland and Bertram in the office, Haffner's invitation to Lisbon, Bertram's invite to Lisbon to join in poker etc. 

Those loose ends point to a few options. 

1. There is a group effort to find RJ off the books before Jane does, so that he can be taken into custody and manage an enormous cover up without knowing that they are being controlled by RJ.
2. The group effort to find RJ is to protect him because of how much he knows.
3. The list of 7 each represents one of the 7 letters in the name RED JOHN, and they are all Red John. The name is not of a person but an organization. Martin only knew 1 of them. Red John knew that Jane would track it down to those 7 because those were the only 7 to track it down to. The buck stopped with them. This is why it was so important that Lennon not recognize Kirkland. Red John could kill endlessly until Jane figured it out and still hold to his (their) own rules. For the writer it also means that they can point clues at everybody on the list without diverging from the story line. Pay attention to descriptions of Red John and you will notice they do not all fit.
4. The list is of the next 6 victims. 
5. The list is of the next 6 accomplices
6. Red John Really does have supernatural powers.
7. 3-6

I think Brett stiles Made the smile face along time ago on the barn, But I think brett partridge is Brett stiles son. Maybe that's how brett stiles is getting all the information
