My friends,
after almost 6 years of failure, let's be honest, Jane is unable to find RJ's identity !
He's so smart this Dexter Morgan's competitor ! Maybe they are friends on Facebook and spend nights talking on Whatsapp about their kills skills.
At Jane's house, when the suspects are together, a striptease began (to find the tattoo, the latest clue).But no chance, 3 of them have the same tatoo. What to do, only 2 episodes to find RJ?
Red John is supposed to be a great leader, very charismatic, very manly.
Then no time to lose, Jane will order them to continue the striptease, it's obvious that the one who has the longest penis is Red John !
I don't why but I bet on Bertram :D
Maybe there was a gas leak during this meeting, and the explosion is caused by a fart of Sherif McAllister !
Surprise, Red John is actually Bob Kirkland's brother, who was masturbating, watching them getting naked through a window.
That's what we will discover at the 8th espisode: Red John is gay and was in love with Jane.
He illed his wife because he was just jealous.
This is the most realistic theory of this site, or else, I have no else explanations ! ;)
