Not a theory but an observation and inquiry on my part....
Some people have suggested that it is too obvious that Bob Kirkland is Red john and he is most likely Miranda Martins boyfriend which would explain why he killed Jason Lennon.
However, after watching Red Sails in the Sunset and There Will Be Blood, Miranda Martins was killed something around 2007.
But when we were watching the episode Red Dawn and the particular scene when Alexa Schultz and Bob Kirkland were talking with Virgil Minelli regarding getting updates on the Red John files, that was around 2003-2004.
So my question is that why was Bob Kirkland pursuing Rj when Miranda Martins was still alive anyway? The timeline of events doesn't make sense....
I don't think Bob Kirkland is Rj to be honest but he must have some other motive regarding the Red John case.
What do you al think?
