I'm the fan that has just posted about Charlotte. Now some people believe that Robert Kirkland isn't Red John but here's what I think.

Reason 1 : Patrick clearly states on there first meeting "Do I know you?" as if he should know him.

Reason 2: What if that wasn't there first meeting? What if they have shook hands before, but somehow Patrick has forgotten, maybe when he had the breakdown.

Reason 3: When it flashed back and Robert Kirkland was in that limo with the woman who was talking to Minelli it is clearly a black limo just like the one Wainright was killed in.

Reason 4: Robert clearly knows about Jane's time in the hospital, as Alexa Shultz informed Minelli on the phone.     

I know some people may find this far fetched - But how many children as Red John killed?

All we know is Charlotte...right? 

But what if Charlotte is still alive?

Reason 1: When he used that girl and drew the Red Smiley Face on her hand, that's all he did, he didn't hurt her.

Reason 2: When Jane drank that tea he saw Charlotte and only Charlotte at the age she would be, why not his wife too? Maybe because his wife is dead.

Reason 3: What if that night they were "killed" and he opened the door Red John was there and brained washed Patrick into believing they were both dead - I mean he did brain wash Kristina Frye into believing she was dead.

Reason 4: Maybe when he had that breakdown in the hospital - Charlotte was there too. But his mind believed she was dead.
I mean when he drank the tea he had a vision and he was in a straight jacket and lying on a bed and Charlotte was standing over him.

Was she trying to get him to remember?

Reason 5: Look at the grave stones you'll see there name and only names. Why no date of birth or death?        

Dean Harken maybe.

The name Harkin means dark red.

I'm not sure who RJ is but I wish people would stop accusing every middle aged man who is seen in the distant background.

Nothing is for sure but these people are most likely not RJ.

Robert Kirkland: Are people really that naive that the believe that RJ's identity would be made that obvious.

Ray Haffner: Again, it is way too obvious. I dont doubt that he has something to do with RJ though.

Brenda Shettrick: Fist off, RJ is probably a man. Secondly, she did not seem comforable in helping Volker locate that little boy.

Bret Stiles: He is too old. I think he knows something but not what evrybody is assuming. Remember that episode where that guy at Visualize killed that girl. Stiles slapped him for it.

Craig O'Laughlin: He's DEAD.

Dr. Steiner: Also Dead.

Grace Van Pelt: Saying that she has red hair is not a legitimate clue. Anyway she is too young.

J.J Laroche: He's to slow and monotone to be RJ. He has a secret, but its one that he thinks Jane knows. When he found out Jane "knew" his secret, he gave into Jane's demands. RJ would not do that.

Kimball Cho: Let's get real here. This is cho. He is too Cho-like to be RJ. Also he was there when RJ killed Rebecca. (and it was probably RJ himself who killed Rebecca based on the Joyful expression on her face when she saw him.

Lorelei Martins: It wouldn't make any sense for her be RJ.

Luther Wainright: Dead as well. Let's stop accusing the dead shall we.

Patrick Jane: He does not have multiple personality disorder. It wouldn't make sense for him to be RJ either.

Sam Bosco: He's Dead

Summer Edgecombe: She has nothing to do with the RJ case.

Susan Darcy: She could have something to do with the case but she is not RJ.

Teresa Lisbon: There are many reasons. She is a girl, she was in the cellar when RJ was watching, etc.

Wayne Rigsby: RJ is a controling narcissist. He could never be as silly and sweet as Rigsby is.

Personally i think that evrything Rosalind Harker says is a load of crap. I think she is more evil than we are led to believe.

Also Rosalind Harker... Dean Harker... Perhaps there is some relation... they do both have Red Hair.

ellis mars,
        There was an episode in the earlier seasons in which one prisoner was helped by jane to escape when he said he had information about RJ. This guy was killed by red john along with an hooker. On the walls it was written in blood: "He is mar". He might have been trying to write he is mars. Also, ellis mars gives his contact card to jane on one episode. The card contained some symbol of a tiger burning bright.

DISPROVE
Hey dont accuse anyone in the CBI team again... ok?
 

No more CHO
No more RIGSBY
No more VAN PELT
No more LISBON

THINK

Okay Firstly I'm going to rule a few people out..

1. Patrick Jane - It can't possibly be patrick because he was on the tv show the night his wife and child died.. also in the last ep of season 2, patrick is not talking to himself, red john is, and also if patrick was red john, wouldn't timothy carter recognise him, when they're speaking together?

2. CBI Ron - Although CBI Ron is a really good suspect, he can't possibly be red john, because in the episode where one of the office ladies in the CBI kills all the members of the team that were on the red john case at the time (not patrick's team) and she gets sent to jail.. and as she's being escorted by Cho and Rigsby along the prison corridor, a man passes in prison guard uniform and the lady smiles at him and recognises him because he's rj, and he squirts some posion on her hand and she dies.. but if that was CBI Ron, Cho and Rigsby would've said "hi" or something, or would've at least acknowledged him as he was walking past..

2. Wayne Rigsby - It can't be Rigsby, because the director has shown too much of his personal side, being a caring father and all, and the director is trying to make Red John look like a cold blooded killer, not someone who is kind and caring..

3. Cho - It's not Cho, same reason as for Rigsby, the director shows too much of his personal side, ie. his realationship with Summer, which shows he is caring and viewers just wouldn't be satisfied if they found out that a crazy serial killer was just a nice guy..

I reckon it's a relative of Brett Stiles. It can't possibly be stiles, because Stiles is just an Old man, he's not strong enough to pull off murders like that, but I do believe that it is a relative of Stiles' because he would fit RJ's age group, plus last episode, it was said that Stiles bought a whole dozen farms, and who better to get to work on a farm, then you're own son?

Anyway I'm probably wrong, but it's up to you to believe what you want :)
