Bob Kirkland is dead at the hands of Reede Smith. This list is becoming 
interesting. Since there is a "powerful" organization within the CBI, 
FBI, girl scouts of America and the Justice League, I think we need to 
organize the list into two groupings.Powerful Organization
1. Rede Smith
2. Sheriff McCallister
3. Gale BertramVisualize
1. Brett Stiles
2. Ray HaffnerSo
for the first four episode, we have seen which suspect of the list is 
associated too. From episodes 3 and 4, there we establish Kirkland 
stumbled upon a powerful organization, talks to Smith and gets shot. In 
episode 3 Smith is seen talking with Bertram and McCallister.It 
is established from what we have learned from episode 2 that Haffner is 
alined with Visualize as he is tasked with looking out with their best
interests gathered from his conversation with Lisbon.So here is 
the enigma, we know from the Red Barn that more than likely that red 
John is or was associated with Visualize. We have established that Brett
Stiles knows more about Red John than Patrick when we see them sitting 
on the park bench while Jane is there getting the location of Frye. 
However, given the events of episode 4 it begs to question is Red John 
in the Powerful Organization or more closely associated with Visualize?If
we take what Sophie Miller had stated in her notes, Red John is in good
health and middle age. This would potentially eliminate Stiles and 
Smith thus reducing the list down to three people. In looking at who 
would be the best fit, I would say it would have to come down to between
Bertram and Haffner just because both are associated with power and 
greater access. That is not to say that McCallister could have a means 
to position and access, but in looking at his status as a sheriff, I 
would think not.Besides I think this plot vise with the Powerful
organization, it would make since for Heller to save McCallister and 
Smith for this vise post Red John arc.The tiger tiger reference
is quite interesting because of the fact this is a password within this
organization. this phrase has also been associated with Red John as 
well. This would make one think that Red John is at the head of that 
organization and that would make the most since. Thus putting Bertram in
the prime stop light. However, like any organization, it takes great 
money and resources to pull this off. Thus Bertram would have to balance
the books and keep it on the down low. Hence this would bring Haffner 
back into the mix as he might have a great cash flow from Visualize.In
conclusion, I think Heller is setting up the post Red John arc with 
this organization. Patrick may catch the whale, but may realize that the
whale is apart of a pod as he has not demonstrated the knowledge of 
this organization, only Red John.
