In season 5 episode 16, Bob Kirkland goes out of his way to get information from CBI. The show doesn't show why Gale Bertram gave Kirkland access, so it's possible that he convinced Bertram. 2 episodes later, he asks Jason Lennon whether he remembered him. Just after Lorelei shot him, Jane said that "he knows who Red John is". The only reason I can think of to explain why Kirkland asked that question is because he's scared that Jason can Identify him. Right before Kirkland killed him, he said, "I just hope, that if I'm ever in your shoes, I have a friend close enough to do this for me."  Kirkland refers to Jason as a friend and most associates of Red John are his 'friends'.

In season 5 episode 5, a woman named Alexis Shultz(?) asks for updates on the Red John case, normally, it wouldn't mean much, but then she turns to Kirkland and says, "Done." As if Kirkland put her up to it.

In Season 5 episode 7, Kirkland goes to Lisbon specifically to ask her to stop pursuing Tommy Volker. It's later revealed that Brenda was a mole in the CBI. She was the reason Tommy Volker knew about the CBI's moves. She may also be tipping RJ off too and he didn't want his leak to be revealed.

Then, in season 5 episode 19, a Jane's attic is broken into, and a man who looks a lot like Kirkland is seen looking at pictures of Jane's evidence board. His face is never directly seen, but his build is clearly visible.

 Everybody says it cant be Bob Kirkland simply because he  was introduced in Season 5 episode 5. However that episode is a throwback episode showing how Jane met Lisbon and eventually was hired as a consultant to the CBI.  When we see Bob Kirkland for the first time its in the back of the limo after Virgil Minelli talks to Alexis Shultz. We then learn that Bob Kirkland has been there since the beginning. We just didnt know that till season 5. 

Now I will ask you this: What was the point of Alexis telling Minelli that Patrick was in an insane asylum? Maybe it was to get Milelli to think think Patrick shouldnt be trusted? Also in the season 4 finale when Patrick when he and "Redjohn" are talking Redjohn mentions the fact that he has a friend in the FBI. Alexis Shultz is in the FBI....coincidence?
 One last thing I must mention. Remember how Bruno Heller mentions the "Where is Waldo?" Game? What does Waldo always wear? Red and white. What does Kirkland always wear? A white shirt and some type of red tie. I dont know for sure if Kirkland is "RedJohn" but it is very good possiblity...

Well, I've been reading a lot of theory, and most of them are discussions of the names on the list (wich is the most likely to be RJ), but... Recently I caught myself wandering how the hell that video from the season 5's finale was made and... Well, it's pretty much impossible if we analyse the facts purely on how they're shown to us.

Like, really! Lorelei was dead just when Jane was still processing his informations to come up with the list! It means that Red John knew EXACTLY how many and what names were on that list BEFORE even Patrick had that! And considering the list could only be made up by the very complete acces to Patrick's memorys of who he shook hands with! Not even a mind reader could do that with such remarkable precision and antecipation.

Some would say that all of the seven suspects are accomplices and that Red John just needed to get those followers who shook hands with Jane, but, for god's sake, Jane eliminated ALL the names of those he shook hands based on alibies for RJ's crimes! Being a accomplice doesn't  leave you without an alibi for the crimes of your master. '-'

Seriously, if you guys can think of anything actually reasonable, clarify my mind because without that I think all of you would agree with me that there's only two other options that explains what happened:

1) The list is fake: Well I don't think this is the case because Bruno Heller said it could be trusted and lying about that would be really wrong >=(

2) Lorelei is alive (or at least didn't die when we thought she did): Now, I really never liked this theory, but... It's the only one I have left! I always thought it would be just WAY too hard to Red John to fake her death like that but recently it just ocurred that Kirkland and the Homeland Security were acually the ones who took care of that crime scene... And if we think that Red John took the list information from Jane's attic, than we do know that our friend Bob did that.
I'm not saying he is the only one that could have done that, but if we look back:
1- He shook hands with Patrick just a few episodes before we got the information that RJ and Jane shook hands (coincidence? Maybe... Maybe not...) and the fact that Lorelei was in jail doesn't mean anything, given the fact that RJ it's not incapacitated at all of ceasing comunication with someone in jail (a.k.a Jared Renfrew);
2- He killed someone that could somehow give a clue about who RJ is, Jason Lennon (don't ask me why the "Do you recognize me?", no clue about that thou it did sounded suspicious as well), and even if some of you would think that was too risky... Well by the time RJ already knew abount Patrick narrowing down some names because of what Lorelei said, so in his place I guess I'd be very worried about any other sudden brake for Jane and being cornered like that...
3- Interest in RJ case since Patrick got into CBI (I mean, com'on! He's a Homeland Security agent!);
4- He fits Rosalind's description (I don't know why Jane didn't exclude half of the suspects because of that description, but he fits it, anyway =p)
5- The whole breaking in Patrick's attic after Lorelei apparently was already dead works very well as a mislead, and I'm sure many of you initially discarted him as a suspect like me after that (so he isn't THAT obvious, like many would say);
6- He is REALLY creepy! (Ok, no need to take this one seriously... =p)


Anyway, that's what I thought. I don't like the idea of Lorelei not being hat by the time we saw her dead but, as I already told you, I can't think of anything else possible...

Robert Kirkland aka Bob Kirkland, an agent for Homeland Security, is one of the 7 suspects for being Red John.

In the "7 Red John Suspects" series I will upload footage containing scenes where the suspects are shown.

Red John is Bret Stiles' son, I'm absolutely convinced about that.

I don't know who that son could be, my favourite choices are Bob Kirkland and Ray Haffner (Bruno Heller: "Suspect list is legit"; both perfectly fit to Rosalind's and especially Jane's descriptions: "very ordinary looking man, mid thirties, medium height, thinning brown hair. He’s methodical and tidy, keep himself very clean. He has a small speech impediment that he’s deeply ashamed of. He works at a clerical job" - points more to Haffner with the clerical thing...). I have chosen Kirkland, cause I think he's the smarter guy: I wished RJ to be really smart and likeable, a totally winning character (which is why I would be disappointed with both Haffner & Krikland: I think, in that way, Stiles would be the best choice so far, although too old...)

Ok, let me know you that I'm from Germany, so I haven't seen the last couple of episodes of season 5 so far, but I know about the list of 7 suspects. Also, I don't know if someone else has already been typing on Red John being Stiles' son, if so, I share his idea.

My 3 reason for RJ being Stiles' son:
 
(1.) Red John has money and influence. Bret Stiles' son would definitely have money, and definitely get access to agencies, high society, etc.
(2.) Bret Stiles obviously knows Red John's identity, but neither is he getting killed by Red John nor seems Stiles to be one of RJ's friends, as he sometimes helps Jane and seems to be afraid of RJ. Stiles is like the father who doesn't want to betray his son though he knows that his son has chosen the wrong path and become someone evil. And: Both, Stiles and RJ have the strong talent to manipulate people... they are totally father & son...
(3.) Every writer needs his inspiration, even if it's a very good writer. I really think that there are some smaller connections between John Katzenbach's thriller "The Analyst" and the RJ story (do not missunderstand that: I absolutely don't want to say (!!!) the RJ-story could be inspired by "The Analyst", there are just some small similiarities): There is some kind of rebirth of the main protagonist as he sees no chance to win the game against his antagonist - Jane pretends to start a new life at the end of  season 4, Rikky (the main character of T.A.) pretends to kill himself; Red John and "Mr. R" (the bad guy in "The Analyst") both are extremely smart guys who seem to have an almost unlimited access to money institutions etc.; RJ and Mr R both regard the fight against Jane/Rikky as a big game; Mr. R. communicates to Rikky using poems (like "Tyger, Tyger"); the big debt Rikky carries with him is that he had not paid attention to people and had used them for getting a career - like the former "visionary"-Jane. And: Mr. R. has a very manipulative father who seems to give Rikky some hints to find Mr. R....

I believe Kirkland is the head of 'Red John,' a cult group of 'subconciously hypnotised' people, brainwashed to carry out his bidding. Theres a long running theme of mind control and this is key to solving the riddle.
Patrick has known Kirkland for most of his life but doesnt realise it, because Kirkland isnt who he appears to be... literally! .... Kirkland has undergone facial plastic surgery to change his identity and is the reason why Lennon doesnt recognise him. The clue is in the trademark smiley face :)
Also, i believe Kirkland actually grew up with Patrick, both from traveller roots, until something happened between them. Kirkland has a list of deciples, all of which are unaware theyre working for 'red John,' until a 'trigger' reveals the truth and a 'Red John' disciple is revealed. Heres the catch... Patrick Jane is the 'trigger' and is unaware hes working for the 'Red John' as well.... weve never seen the crime scene of patricks murdered family and theres a reason for that :)

Well first of all i think it's a great series.My theorie is based on facts.It is impossible that any of the crew or even Patrick(saw this posted with a spilt personality factor) could be Red John because at the end of the last eEP series 3 Red John kills the secretary(his acomplice) on the hallway of the station while the whole team is upstairs filmed in the same place.We get a slight look at RJ's back that lokks very much like Kirkland(hight weight and hair)2nd ofc he has acces to all the files all the facts about the cases and if he can compete with Jane intelectualy he could have figured out the list.The List is not bogus(the director states we can trust that list).If we watch all the scnes with Kirkland we find the one he shackes hands with Jane the first time and it is obvious the director wanted us to notice that.When he and Lisbon interview L.Martins mother is also a scene where he gives away nhis true nature.(take a look at his mimics).It may also be the case he has got more surprise accolites and some even on Jane's list.
