Hi all,
Like most of you I was also convinced that Brett Patridge is Red John. But now that he is dead as confirmed by Bruno Hellor, I checked all 7 suspects again and finally came up with one name - Ray Haffner. My theory is as follows.
1. We have seen that Red John is technically sound as he has hacked into CBI firewall many times. Also, he is very good with surveillance techniques as seen in Episode 1x23.
The same goes for Ray Haffner as seen in Episode 4x02 in which Lisbon describes Haffner's strength as surveillance techniques. Also, being a member of Visualize Ray Haffner is probably connected to some of the big guns of the state as well.
2. A key point which I over looked first time was that In Episode 4x02, Ray Haffner holds his tea cup in left hand while talking to Grace Van Pelt. In the very same season's Episode 4x13, we seen that
Red John also holds tea cup with his left hand. Coincidence???
3. Rosalinh Harker's description of Red John matches exactly like Ray Haffner's. The only difference is the voice which has thrown off most of us. But I think Haffner somehow changes his voice with some devices or gadget, I guess. And this makes complete sense. Would an incredibly careful and clever killer like Red John flaunt his actual voice ???
4. Red John somehow managed to hypnotize Kristina Frye after he captured her. He made her believe that she had died and turned into a spirit.
We know that Ray Haffner was a member of Visualize . I assume that he learned hypnotizing from there.
5. One of the biggest clues about Red John that we found in Episode 6x01 is that he addresses Agent Lisbon as "Teresa". He uses her first name as if he is Lisbon's friend.
Among all the 7 Red John suspects, Ray Haffner is the only person who calls Agent Lisbon as "Teresa".
6. A big question arises in the climax of Episode 6x01. Why did Red John spare Lisbon's life. Patrick Jane feels that Red John got spooked somehow or there was lack of time. It may be true.
But another possibility is that Red John has feelings for Lisbon.
Ray Haffner also expresses his feelings for Lisbon in the very next episode (6x02). He says he likes Lisbon and hopes to have a future with her.
7. And finally we come to know about a habit of Ray Haffner which makes him a very favorable Red John suspect. Sophie miller's notes says Red John is a good whistle blower. And so is Ray Haffner as he whistles in the hospital after meeting Lisbon.
8. Now the biggest clue of them all. Remember Lorelei reads out the list of suspects at the end of season 5. While she reads out the names, she takes a long pause before saying Raymond Haffner. I assume that Lorelei was surprised that the actual name of Red John is in the list.
