I really dislike the theory that Partick is Red john, i think it will loose the point of the plot of the drama, its nice to have faith that Patrick could actually be the only one that can out smart red john. 

I also dislike the theory's on that it is the main characters. 

Wayne Rigsby - I think the way He acts in most of the episodes, is proof that he's not red john, he is a bit too clumsy, and makes allot of mistakes, while i think red john is a bit more careful and meticulous 

Cho - I don't think its cho, He looks so small to fit into the 6" guideline and also, we are also lead to believe that red john is a white man, so this could rule cho out. 

Lisbon + Grace - While many people think that red john could be in fact, a girl, we are lead to believe that  red john raped Miranda before he killed her and the silhouette we see of red john in episodes, is defiantly not womanly, Just because Lisbon is so interested in what Patrick is up to doesn't mean she is a killer, i mean wouldn't anyone want to know what he was thinking about red john? i certainly would! 

While i do think Brett partridge could be a likely suspect to be red john, there are a few reasons why i think this could not be plausible. 

1) He shows an active dislike for Patrick  don't you think red john would be a bit more clever, than going shouting  his mouth of about how he actively dislikes him? 

2) Whenever he's at a crime scene, he is always trying to persuade Patrick that it was red john who committed the murder, when it turns out that it was not red john who did it, or trying to convince Patrick it was red john, when it wasn't, i think red john would be a bit more clever,  Trying to throw Patrick off guard that way, its a bit of an half-hearted attempt isn't it? 

3) He's a bit too easy to find, he works at the CBI in the forensics, while this would explain why no DNA or evidence if ever found leading to red john, (because he knows what he's doing) he's a bit too easy to find, and Lorelei wouldn't of treated it as,much of a task when seeking was him out, if he would be working at CBI in the morning. 

I think Brett Styles could be Red john, as he is good at manipulating people, shown when he nearly convinces grace to join visualize, He has the money and power, and could be quite hard to find when Lorelei was out to get him, as i could see him quite easily being able to disappear without a trace. Also whenever Patrick asks him for a favour, it always turns out in red johns advantage. He wanted Patrick to find kristia Fry, But however, Red john seemed to be angry that Lorelei told Patrick that He had met him. I think If it is not Brett Styles, Red john might of used to be a member of visualize  and may of admitted some things he regrets saying, in one of them one-to-one meetings they have at visualize to "clear their conscience", and scared Bret stiles into being one of his allies.

I also think there is a chance it could be Gale Bertram, Patrick had him as a suspect in the episode "strawberry's and cream", He obviously Has a bit of a dislike for him, and thinks he is capable of killing someone, while Patrick said in an earlier episode that brett styles "could not hurt a fly"

I wish i had put up my personal list before the episode came out.
From the seven names i came up with only 4 were right.
Sheriff Thomas McAllister, Robert Kirkland, Ray Haffner & Brett Partridge.
I thought both Bertram and Stiles were too old to be Red John and Reede Smith was someone i didn't suspect at all.
My main suspect is Thomas McAllister, i always remembered him from the first season because of the actor who played him.
When he showed up in the 30 suspects list,  i had a gut feeling it was him.

Many people have already dismissed him and Reed as Red John but i disagree with their reasonings.
Many refer to the fact he was only in one episode of the show so far but Red John has been stated to be a Waldo type character in terms of appearances on the show.
Most people seem to mistake this as he being a character which shows up every couple of episodes but thats not the case.
The point of being a Waldo type character is that he is always in the background but almost never seen.

This fits with the idea of McAllister being Red John as every other time we have seen him in the show has just been a glimpse of him.
It could have been his back we saw when Rebecca was poisoned as both law enforcement uniforms of her killer and McAllister are similar.
His overall demeanor from the episode he was credited to being in was that he was suspicious and creepy.

Patrick has stated before that Red John is a showman and with this we can premise that him loosing to patrick in rock, paper, scissors and being frustrated and baffled was just an act.
Everyone on that list has been one upped by patrick one way or another whether it by destroying a team to a toothpick in a door.
The idea that Patrick made him look silly, thats why he couldn't be Red John is a stretch as he has done that to others as well and unlike the rest his act was easier to pull off.

Another thing i'll mention is that people state that his actor isn't charming/good looking enough, if you haven't seen how his actor really looks like(without the mustache and the shaven beard) i suggest looking at his imdb page http://www.imdb.com/name/nm0075359/.

I also believe that Reede is an accomplice of Red John and that he wasn't just added to fill up the list.
To me he is so out of left field that i believe he has some connection to Red John i believe the list not only has Red John on it but his contact in the FBI.

I would like to add that i think Todd Johnsons murders of cops ties in to the fact that the Sheriff wanted to get rid of certain individuals in law enforcement that he felt were too suspectful of him as in his personality/behaviour and not that they knew he was Red John.

Finally i would like to mentioned the fact that people state that he was too small time to have that many devoted followers and that some were so high up authority wise for him to be a real possible candidate of red john.
Even for a small time Sheriff, everyone who knew of him throughout the episode he was in thought highly of him even though we as the viewer saw the darker side of his personality which no one else knew of.
I believe this charisma he has and a hypnosis type skill he uses has been the reasons why he has such influence over so many individuals.

As for the fact he knew a personal memory of Jane's, i would say that he was either there when Jane was a kid or most likely got the info out of Jane under hypnosis when Jane was inside the Mental Institution.
On the matter of Red John knowing the list, i would say its a suspension of disbelief as Red John is stated at this moment in time to be smarter then Jane and the fact that Jane was able to come out with 7 names shows that Red John should be able to as well.

I admit I have been wrong all along.  I still don't have any concrete idea as to who it is.  I do however think that a key clue to finding out is determining how Red John knew which names Jane had picked and how he killed someone from his memory (a good memory that made him happy).  To me, it has to be someone that has hypnotized Jane at some point.  Red John has proven time and time again that he is a master hypnotist.  That being said, it must be someone that Jane has spent much time with..........most likely one on one time.

I am thinking Ray may be a good choice because he spent a fair amount of time with Jane alone.  He reasonably fits the description's given as well as age.  His name is Ray which doesn't deviate much from Roy.  Jane had said i a previous episode that people usually pick aliases that are very similar or have a connection to their own name.

Like I said......it is still a huge guessing game at this point.

Not a theory, just some thoughts.

1. We don't know for sure if the "list of 7" is really Patrick's list. Patrick didn't give us his list, he just showed Lisbon (and us) some cards with some faces on them. After he had already seen the Lorelei CD. Maybe it's his real list, maybe it's not. We can't know.

And no, I don't care what Bruno Heller has said. And by the way nowhere does he say "yes, RJ is one of the seven". He just says "no more twists", which could mean anything. 

2. Something is really wrong with Kirkland's name being on RJ's list. 

We all know about the handshake inconsistency here (Lorelei being in prison when Patrick shook hands with Kirkland) and we can safely assume Patrick knows too. Why would RJ list Kirkland's name? Some possibilities:

- Lorelei knew that Patrick shook hands with Kirkland, despite being in prison when it happened. If this is the case, than how did she know? Kirkland told her? Someone else in the CBI saw them shake hands and told her? And by the way, why would anyone tell Lorelei that they shook hands with Patrick at all? Can you imagine RJ visiting Lorelei in prison and telling her "hey, Lorelei, just so you know, I shook hands with Patrick Jane"?

- Patrick's list is real and Red John somehow obtained it. It must have happened before Kirkland had those people break into Patrick's room (Lorelei was already dead at that moment). If this is the case,  than why would Patrick put Kirkland's name on the list, knowing that he shook hands with him when Lorelei was in prison? And one more thing. If Patrick already had a real list by 5x16, then what was he doing in the next episodes? Imitating hard work?

- Patrick's list is a fake that he designed in order to mislead/trap Red John and Red John took the bait. Again, RJ did not get the list from Kirkland.

- Red John is merely guessing and for some reason Patrick makes Lisbon (and us) believe that RJ has the real list. This would probably mean that Patrick suspects Lisbon.

3. How does Red John know about some obscure childhood memory of Patrick's?

Again, possibilities:

- Red John has real "powers". This would mean that Bruno Heller and co have made a turn towards X-Files territory, which seems ridiculous.

- Red John is someone from Patrick's past, someone really close to him, someone who knows him very well. Father, brother, childhood best friend, something like that.

- Patrick has in fact told someone about this particular memory (and probably other things too). Red John recruited this person and/or tortured/hypnotized/whatevered them into telling him things.

- Red John gathered the info from the mental institution, that Patrick was in after Red John murdered his family. Patrick may have shared - willingly or not - some private things with doctors, nurses, other patients.

- Red John has hypnotized Patrick.

- Red John is Patrick.

That's it. Thanks for reading. ;)
