If I were Patrick Jane, I would have easily found out who RJ was. Simple, gather all the 5 suspects at his home. Give them coffee or beer or anything to drink with sleeping pill spiked in them. Once all of them fall asleep, check the ones with tattoo and bring Rosalind Harker to identify who Roy is among them. That would solve it. Simple. Bruno Heller does not know how to write stories. Poor him.
I just hope that atleast Reede Smith is not Red John. He does not fit any criteria and the guy who was in Harker's home was thin, even his fingers were thin. Still in the ending, if they portray Reede Smith as Red John, then this will be the worst series ever on TV. All the clues thrown at us were fake. I think it might be Bertram. Remember Red John told that he found out when his good friend in the FBI found out. Both Smith and Bertram are in Tiger Tiger group. And looking at how things might turn out, Bertram might be revealed as Red John, so in a sense all the clues still stick together and yet the fans will be disappointed. I don't see any reason why Reede Smith would be Red John. He wasn't there from the beginning. Only Mcallister was. So the entire logic has been thrown out of the window by Bruno Heller. The reason why nobody is able to predict who Red John is exactly is because everyone is trying to use logic whereas Heller does not have one logical theory. So whatever you do, in the end I just hope that it is not Reede Smith.
Now the list is down to three. Everyone knows that RJ is now a tyger tyger member. But who could Red John be? I guess many of us would believe it to be either Bertram or Mcallister. Very few would think Smith to be Red John. Why, because there is little or no proof to say Smith is Red John. All the clues from Sophie miller and Rosalind Harker prove Smith is not RJ, except for one. Smith has fear of heights. Now everyone would be really disappointed if Smith was RJ. He does not look like one. If there were no clues by Harker or Rosalind, then I would have thought he might be RJ. RJ could be either Mcallister or Bertram. But one question remains, did anyone know about who Red John was in the tyger tyger community. I believe it was Smith who really killed that woman. Let us wait and see who RJ would be. If it is Smith, then I would have to say that all of Heller's clues were wrong and he is nothing more than a sloppy writer.
Without much doubt, I suspect Mcallister because of the following points:
1. He is around 6 feet tall.
2. He has rough hands
3. He is not muscular or soft
4. He has short straight hair.
5. He is very calm in the roughest of times. Look at the next episode, even Brett Stiles got scared when Jane pointed a gun at him but Sheriff looked unmoved.
6. In the room with Bertram and Smith, look closely after Jane leaves, how Sheriff is staring at Bertram. He is the only one in the room who sounds a bit shocked when Jane talks about Sophie Miller. Jane cannot spot he is faking it as he is a pathological liar.
7. He wears the same shoes as RJ.
8. He said he likes to hunt anything with a face. That makes sense.
9. In season 6 episode 3, at the end look at him shooting the suspect, bull's eye. RJ too had shot accurately in season 2 finale
10. He shot with his right hand in the season 6 episode 3, while he uses his left hand to pull up Jane and to use his walkie talkie. Well apart from him, RJ is the only one who can use both hands easily.
11. None of the other suspects have been shown to be smarter than PJ except Stiles. But if you watch the episode 3 of season 2, you can clearly say that Sheriff is a lot smarter. Even Jane was surprised when he climbed the ladder. He said "where did you come from?" Only RJ has been able to outwit Jane till now. Maybe Sheriff got to know when they visited Napa that they had come to investigate him. Thats why he kept a close watch on Jane.
12. His age according to the script will be around 50 by now. So the Kid at that farm would be around 21 years old. Fits it.
13. The kid portraying Sheriff looks very much like him. Its got to be him.
I made some observations, some of which are old and some of which are new. They make me feel that Red John is Haffner.
1. If you see the scene where Rosalind calls Jane and says "Roy is here", RJ sits with tea cup in his left hand. Look at the way he sits. Now compare this with the way Haffner sits when he visits Lisbon in her office. He sits exactly the same way. The camera will show you that for just a few seconds, when he is talking we see only his upper body. I think this could be a vital clue
2. He is a surveillance expert. He can watch people using all his resources, that is why he is ahead of Jane.
3. He was 21 and was in Elliston Farm when he was a member of visualize. He tells Lisbon that he doesn't believe that Brett Stiles is God, but happens to believe in somethings he says. All other members of Visualize believe Brett Stiles to be God, only RJ can say like this.
4. The way he walks in the hospital in Season 6 Episode 2 is exactly the same way Red John walks in Season 2 Episode finale, where he kills RJ copycats.
5. Well built, not too soft or too strong, his hands look exactly like Roy, medium aged man, height is just below 6, short hair, good looking. All this fits him.
I think any of the seven could be Red John. The only ones that match the physical description are Kirkland and Partridge, rest all are either fat, old or a bit tall. Bruno Heller told we will be disappointed when we find out who Red John is and he could already have been cast. Hence it is axiomatic that RJ could be one who is very self-obvious or someone who has not been shown. Hence it could be the two new characters Mccallister, Reede Smith or Partridge or Stiles and not anyone else.
