At the moment we can elimanate the following as Red John
Wayne Rigsby - when Loralie crashed her car in to him in s5e16 she was s angry and wanted to kill RJ if he was RJ then she would have killed him there and then
Patrick jane - Come on its not him so many reason that it is not him one s2e23 how can he be 2 peolpe at once s4e23 how can he be having a comversation with him self its not
him
Bertram and Kirkland - I beleive they are acomplices of RJ not RJ him self
Alex Jane - why would you shake hands with you dad and then be best friends with him
Vanpalt' Hightower' Lisbon' Shettrick' Harker' Frye' Darcy and Shultz - all are female and all of Red Johns acomplices that get caught refer to him as a HE and that he loves them and sttufe he has to be a guy unless they have all been lyeing
Brett Stiles - could be him but i reckon way to obveous
Angela jane ruskin - jane saw her body and said that her toenails were painted with her owen blood so she is dead
Thats all I can think of at the moment but there are defintly more really that leaves us
Cho' Ron' Minalli' Laroche' Ardilles' Halfner' and then the other few peolpe that come and go kinda thing personly I think it is Minalli as in season 5 episode 5 where it shows jane as he first begins at cbi ande he wants the Red John files but theyc ant just give them to who ever wnats them so Minalli as RJ wants Jane to have them so comes up with a plan you renember the other cop that was there i cant renember his name who walked to the elevator with Jane then Jane pissed him off and the other guy punched Jane in the face renember?
Then they took him in sat him down and Manalli especaly was concerned about him presing charges i think thats right well what if the other cop was an acomplice of RJ (Minalli). then Minalli told him to get Jane angry and to punch him so that they could give him the RJ files as like a gift for his word that he wont press charges as he wanted Jane to try and catch him what do you think ?
