Trying to expose an original theory, which probably you haven't read yet.
Let's take the list of the seven suspects:
Dead ones:
-Brett Partridge
-Ray Haffner
-Bob Kirkland
-Thomas McAllister (but according to the 6x08 Promo Trailer he is probably still alive, but of course for many reasons that you can found in other RJ-theories, he is not Red John)
-Bret Stiles
Alive ones:
-Gale Bertram (oh please, if he is Red John, I am Walter White)
-Reede Smith (of course, he is not Red John)
No fake deaths. It would be so boring and artless.
But, in the list of the dead ones, there is a man who could be dead and alive at the same time.
Bob Kirkland. In fact, according to Bruno Heller who said that the list of the suspects is correct, he is the only one which could still be Red John.
And this is possibile if the one who has been killed is not Bob but Michael Kirkland, his twin brother.
A simple man replacement with the help of the Blake Association and Reede Smith killed the wrong Kirkland, who probably agreed with his brother to sacrifice himself to help him (to remember how clever is Red John to manipulate people for his own purposes).
What do you think about this theory? Personally, paradoxically, I think it is not true, for the simple fact that I myself have other possible and interesting theories like this, as many of you.
