Sorry I don't know all the seasons/episode numbers to reference here, but didn't Roy Tagliano (Red John) supposedly travel around in a pick-up truck? Wasn't there a pick-up truck stored at the cabin where Lorelei took Patrick to hide out, she said it had belonged to Red John?

Did anyone find it coincidental that Reede Smith drove up in a pick-up truck when he killed Bob Kirkland? 

Is it possible Kirkland killed Brett Partridge, assuming he was on the "list" Kirkland had? Kirkland is torturing Partridge when Lisbon shows up, pushes Partridge in the closet, hides in the other room, tazers Lisbon from behind, drags her off and paints a copy cat face on Lisbon to cover up the murder?  He has the voice to be a pretend Red John on the telephone with Patrick and he has no reason to kill Lisbon....

I find it coincidental that Kirkland uses a tazer on his victim, drags him off and tortures him...... 

the pick-up truck and the tazer have me wondering.....
