Sorry for my English, I'm from Venezuela.
This is not an accusation, but did someone remember the last episode of season 3?
There was 4 suspect on Laroche list and they make us think that one of them is the RJ accomplish, then the dispensable killer goes to the last floor with the intension of goin one floor down and kill Hightower. But there is a funny fact here, what is the dispensable killer was not going to go down just one floor down? What is all four suspect even including Laroche are connected with Red John and they all gave him the address so he could think send the dispensable killer to all floor looking for Hightower since he know all addresses or just sent the killer to Bertram floor so he could distract them for O'laughlin to kill Hightower and then sent Timothy carter to the mall where Jane met with Bertram since Bertram is also an accomplish of RJ he told him they will meet in that mall
