I think red john is James Roday who plays Shawn Spencer in the show ( Psych 2006 ) check his voice in you tube , there is a scene when he talks about the mentalist in the Psych show , the video name is exactly like that ( Psych Nicknames 2 0 ) without the brackets , and his voice is 100% red john's voice
I Found this interesting theory
i think i have figured out who RJ is..It is Reede Smith aka Reede = RED. Smith = tagliaferro
i think it is a very strange coincidence that smith is the english synonym of the italian word tagliaferro. and that his first name is reede. as they love in that show to make word games, i think it is a strong indicatation that he is red john. also, i dont think red john is a dominant or striking character like partrige, haffner, stiles or bertram. rj is the one you would never guess he would be rj. i am convinced it is reede smith!!!and reed here the quotation on sparknotes on the poem "tyger, tyger" (might be a coincidence, or might not :-):"The poem begins with the speaker asking a fearsome tiger what kind of divine being could have created it: “What immortal hand or eye/ Could frame they fearful symmetry?” Each subsequent stanza contains further questions, all of which refine this first one. From what part of the cosmos could the tiger’s fiery eyes have come, and who would have dared to handle that fire? What sort of physical presence, and what kind of dark craftsmanship, would have been required to “twist the sinews” of the tiger’s heart? The speaker wonders how, once that horrible heart “began to beat,” its creator would have had the courage to continue the job. Comparing the creator to a blacksmith, he ponders about the anvil and the furnace that the project would have required and the smith who could have wielded them."
Why would Lorelei tell RJ that she told PK that RJ and PK shook hands , i mean Lorelei hates RJ now , because RJ raped and killed her sister,and in the RJ video RJ said "Lorelei told me what she told you about shaking my hand" , because he wants to cover on who ever told him which is Lisbon , because Lisbon is the only one who knows that Lorelei told PK that RJ and PK shook hands .
Robert Kirkland. My guess would be him. it appears he is hiding something. He and patrick jane shook hands. Kirkland told him that he knew Patrick Jane when he shook hands. My Final guess would be him and perhaps maybe Bret Partridge could be Red John.
