I saw some theories that some people think it might Be Janes Father. I had an interesting idea hat its possible jane and Red John could be brothers or half brothers. Where is Janes parents anyways? Does anyone know where his father is? Did I miss a clue on the subject?Sometimes I thought at one point Bret stiles might be Red Johns Father.

i have a little twist on things. i think it would be so cool if grace van pelt ended up being red johns accomplice or something and thats why she joined the CBI. because grace was the last to join the team so maybe she joined to get closer to jane and get info to give to red john. just a little cool theory i had and wanted to put out there. it's highly unlikely, i'm just having a big imagination :D

Red John is Duke, Sherrif Dumars deputy. It looks exactly like him leaving the room where he was holding Rosalinds tea cup. Besides, I doubt he would be far away as all the stuff was happening. I think he is Duke, the guy that got hit by Mace Guthrie.

They had an absent mother and an abusive father plus it will cause a dilemma for jayne later on because Lisbon is his friend.It creates a conflict of him not being able to just go out and kill the guy without a moral dilemma for him.

In the episode "Red John's Friends," the Director of the CBI coincidentally leaves "to visit (his) sister in Hawaii" just prior to Red John's murder of the ex-con who at least indirectly knew him. We also found out that Red John has access to the CBI Computer network and can manipulate his way through communications with Patrick and the others. My fiance and I were subsequently thinking that Red John might be the CBI Director. What will need eventually to be explained is who exactly was having "(his) feelings trifled with," the specific context involved and who Patrick himself might think Red John might be. Surely after five years--now six--of agonizing guilt, he remembers in great detail the specifics of the person he was conning and how that person might connect to Red John. Will no doubt be a great television ride...

The writer gave us one too many clues. The Chief of the who CBI is the guy. Near the end of a recent episode, he quoted a line from a William Blake poem. The bald headed guy who has replaced Hightower informed Jane that the quote was a William Blake line when Jane asked. No big deal there. BUT, guess who wrote the poem "Tiger Tiger" burning bright??? WILLIAM BLAKE. Ergo, the boss is either Red John's inside guy, or he is actually RED JOHN. I am betting he is Red John. Cheers!!!
