I'd like to point out that when you pick up a drink, you usually do it with your weaker hand/arm. Just like many of you right now could be resting your chin in your left palm while laying down or sitting, scrolling. 
Also, Pigeon lady looks familiar, ring matches the same sort of style red john has but it looks like partridge as a transexual and partridge is dead. 
If you were Bruno Heller and his brilliant mind, who would you think up as RJ? 
Also, my money goes on Haffner since he smells of evil. Or Mashburn. 

Just a thought.
