I think red john is a group  of people maybe 3 or 4.
it explains why so many people act suspicious , they want you to try and pick out one when it may be all of them. Also there were 4 people that went to go see that psych that just got killed.
Plus we have seen a few of them that cant stop whistling

Dear all, my name is Red John.

I am not a single person.
I am many, consisted of all individuals who are following my path.
Its a higher path, a nobler existence.

Stop wasting your time on speculating about who I am.
I am in all of you, growing and waiting to erupt.
Stop questioning and find your answers in yourselves.
Take a deep look in your souls and recognise your path.
And then, what you fear, you will become.

You are Tyger, not a lamb.
You are Red John, I am Red John, We are Red John.

Hi

I always like doing a little recap to rethink some of my previous theories. My opinion, since I've seen him, has been that Patrick's father, Alex, is Red John.

I have not seen the second episode yet of season 6, but from what I see it seems to have placed Haffner in the spotlight.

We need to remember that even though someone may fit a set of clues down to the last detail, there must be a reason for someone to have been written in as the main antagonist of any story. When taking this into consideration, Haffner does not seem to be a good candidate as he showed up from nowhere into the story and has been pretty inactive when it comes to the main story line.

I am of the opinion that more than one person is involved in this saga. I will list some of my less likely scenarios in a moment, but first I want to look at recent things which I feel are significant:
1) Partridge's death - honestly, I've watched it over and over a few times but I just can't make out what happens to Teresa at the end of episode 1 in season 6. It seems like she falls over, from where she stands there is a window behind her, either Red John is outside that window or on the floor . . . . . . . ? I know Partridge was announced dead in episode 2 but we know Red John has influence on the goings on in the CBI. If Brett were RJ, it may be that he staged his murder to get PJ off his trail, as Patrick asks him earlier in the episode whether he really has no idea why Patrick is looking at him like that.
2) The list of seven - So Red John does this neat thing where he calls out Patrick's list two months before Patrick has the final list of seven. But when Patrick realizes someone broke into his room, he smiles. Did he lead Red John to these 7 names? Was this his way of weeding out Red John's helpers? 

Red John was said to have contacts in the CBI and FBI. This kind of primarily excludes him from actually working for the CBI.  But then again Red John obviously is not one person working alone. So lets ask ourselves again, what would the reason be (for undoubtedly, if he were real) the most successful serial killer, would overthrow a whole police department to torture Patrick Jane?  It MUST be extremely personal.

I will, until it is revealed to be otherwise, stick to believing that Alex Jane (Patrick's father) is the mastermind behind the Red John group. He is Red John. My theory is as follows:
1)Patrick runs away from a life shared with his father, conning people for financial gain, with his wife. This may have enraged his father and made him hate Patrick's wife and family as he feels they 'stole' Patrick away from him.
2) The Tyger - This poem revolves around the question that why would God create something like the devil who is the exact opposite of what God is.  This could mean that after Jane left his father, his father may have taken on another 'student' or 'students', this may be where one of the seven comes in. Or more than one.  Patrick's father may have taught someone in the list what he taught Patrick, and they are working together.
3) Red John must be old enough to have been in visualize for many years, or been in visualize many years ago. Patrick's father would fit that clue, and Brett Stiles said he knew Patrick's father.
4) The only person who may be able to match what Patrick can do, would be the one who taught him what he knows (once again refer to The Tyger). His father would know what his next move(s) would be and thus it may seem as though he's 'psychic'.
5) The childhood memory - The lady that is killed by Red John is revealed to have been a source for a happy childhood memory of Patrick. Who else would know about this but his father? 
6) Just as a general point, I think we've seen enough of his father, been told little enough about what happened to him and that he is a big enough blindside for him to be revealed as Red John and have everyone be surprised.

One of the scenario's I considered was that Patrick may corner one of the seven suspects and in their death or in the moment he has them in his hands, that person reveals that his father is Red John, and the particular suspect was either his father's prodigy or even Jane's brother he did not know about.

As I said, I will stick with my theory until the reveal is made, but before you submit another theory, just remember that you have to think story-wise what Bruno Hellar's move would be. Would he really dedicate the build up to the reveal piling on evidence for one person so we know beforehand who Red John is, or does he want to keep us guessing until the reveal? I think that if an episode points to someone, we can safely say that it is a red herring. 

Red John will be someone who no one has supected and who may have been dismissed on multiple occasions.  

At the end of S6 E2, while listening to Sophie Miller's record, we see that all of the suspects have different sides which we haven't known. Thomas McAllister, Ray Haffner and Reede Smith, they all whistled in that episode too. This must be an obvious clue.

'He is mar'.. still may be 'He is many'. When Jared Renfrew was about to die he must have written on the wall, sth that would matter.

Consider you were killed and in your last breath what would you waste it for? For the killer for sure. Since the list was too long to mention, Brett Partridge just said 'Tyger Tyger'.(Just like Todd Johnson). This phrase must be like a symbol for Red John society I guess.

It must be a community. Then why would McAllister, Gale Bertram and Reede Smith would make that talk in S6 E2? It's getting more and more obvious that they're all involved. Working as a team, there must be only one killer since the differences on the bodies would be understood by the police. However, we aren't only looking for the killer.

going into this 2nd episode, haffner was my prime
suspect. his fondness for lisbon seems to give him the best reason
for keeping her alive, when killing her appears to be a pretty
obvious and immediate way to hurt jane. maybe red john is constantly
'playing' with jane in order to humiliate him – to show he's
'unworthy' of lisbon, and/or the other women in his life? haffner
seems to me the most likely person to be able to walk through cbi's
halls, and poison rebecca after she was caught killing bosco's team.
he's shown an interest in playing agents off other agents, as when he
unsuccessfully appealed to cho to spy on jane. that could be a way to
squeeze increasingly suspicious cbi ron into the plot – as one of
haffner's moles. right now the only compelling thing working against
my suspicion of haffner, for me, is the whistling thing. it seems too
'apparent' as to be purposely misleading. i may be in the minority,
but even after how weird it was for lisbon to go into the house alone
in the premiere, i actually DID enjoy lisbon at the hospital saying
to haffner 'turns out red john's not that tough,' which was obvious
baiting. it shows she's willing to put herself in harm's way if it
would mean uncovering red john's identity, which is noble,
courageous, and the last f%$#ing thing I would do. ;) 


it probably doesn't make any sense, but i either feel like haffner
is the most likely red john candidate, OR the most likely person to
be the next victim of red john. i just have this vision of him in a
pool of blood calling to lisbon, with a subsequent subplot of her
feeling 'guilty' that she suspected him. i believe he's the only
person on the list, after partridge, that lisbon would feel guilty
about suspecting.
 

when rigsby and cho are talking in the truck, it shows how
everyone thinks red john is someone with “influence,” because of
the mysterious things he can do. but we get one 'mystery' solved when
we learn he used the psychiatrist to learn about jane's memory. i
think heller's comment about being disappointed at red john's
identity has more to do with the general nature of storytelling. the
reveal is never as fun as the mystery. we'll be disappointed to find
red john is only a man, when he has perpetuated such heinous crimes
and clever manipulation. but in reality, his biggest asset is that no
one looking for him knows who the hell he is. that's how he can hide
his tracks: no one knows whose tracks they are trailing. so while
they mention stiles and bertram as being the most influential men, it
seriously makes me question them as viable suspects.
 

my strong hunch after episode 6.02 is that we can eliminate
everyone in bertram's office as being red john: bertram, mcallister,
and smith. i'm guessing the plot line will be that they are somehow
crookedly involved in the drug ring which they pretend to fight.
kirkland sounded similarly suspicious asking bertram of lisbon, 'can
we trust her?' so he may also be in on it.





they might want to be kept informed on the red john case either 1) to
jump in at the last minute and take the glory, as a cover for their
shady dealings, or 2) just because knowing the red john case is over
means jane would likely stop working at cbi. they want jane gone so
that he doesn't figure out their illegal activities, because he's so
perceptive. maybe suspects on that “fake list” in upcoming
episode 4 are dying because kirkland is 'speeding the process' of
whittling down the list, in order to 'solve' the red john case for
jane, so he goes away and doesn't discover the “crooked cop”
ring. i guess i haven't ruled out that they are working for red john.
drugs could more meaningfully tie into his story. we already know
speed was floating around the red barn...




lack of faith part one: i'm not sure i trust rosalind harker's
description, because she loves red john. the whole series we've been
shown crazy, damaged people who seem normal on the surface, but will
do dark things out of their 'love' for red john...including killing
themselves. maybe he's using drugs as part of that control process. i
really want more explanation on that part – not how he gets the
disciples, because we already know he either charms them, or finds
them in states of vulnerability that he occasionally creates. but the
actual turning process.



the last of the 3 men working the red barn, the one that the 16
year old daughter is shown to shoot in the flashback to protect her
mother, could have been an early 'experiment' in mind control. he was
so amped up he shot the pig in the heat of an argument. maybe red
john killed the other 2 men because they proved less tractable. the
drugs were given to him by that small town sheriff, whose 'scary
people' suppliers were connected to the drug ring that bertram and
company perpetuate.




lack of faith part two: thing is, i don't completely trust the
psychiatrist's comments at the end of 6.02, either. red john has been
shown, either through disciples or his own efforts, to be reasonably
tech-savvy. i find it hard to believe he'd miss a tape recorder in
her desk's top drawer. it could be manipulated information, meant to
be found. we don't know what he did to her before decapitating her.
she may have made the recording under duress.




it is genuinely fun to watch how lisbon, jane, and the team try to
act 'naturally' around the suspects. but 2 episodes into the season,
a very strong suspect has seemingly been eliminated, and the writing
is going out of its way to make everyone left appear extra
suspicious. i understand that's part of the 'fun' for us to figure it
out, but it seems like some sort of collective red herring. while
we've been told partridge is dead, seen a body bag, and been told
that it was partridge's blood on lisbon's face, i just can't take him
off the list. i know that is lame, but it's fun. i support the 'network of individuals' theory for the same reason. plus, red john has
made bodies disappear before. maybe i've read too many comic books
where the characters come back from the dead. ;)




but my third lack of faith is: i don't trust bruno heller. in the
interests of a good story, i suspect he'd lie. not my original line,
but it has been said, “all writer's are liars.” :)

Just a thought, not really a specific theory per se. But, did anyone else think that maybe the psychiatrist's recorded messages were forced by RJ to completely set Jane off course in terms of the description of RJ? I say this because I feel RJ wouldn't be careless enough to leave that recorder lying in the desk so obviously and easily found by Jane.
