First, I think most people would agree Gail Bertrum is not Rj, he is just a well placed pawn in Rj's scheme to stay a step ahead of Patrick. When Bertrum arrives at the crime scene towards the beginning of episode 2x6, he calls for officer Sheridan. Sheridan looks jus like the Rj follower who came in and killed Bosco's secretary in one of the previous seasons. Bertram asks how Lisbon is doing and if he ID the second body. When Sheridan says ya we got Bret Partridge, Bertrums reaction is key and raises suspicion. He stops and looks shocked as if he wants to ask the officer are you sure it's Partridge like he knows that can't be possible seeing how I'm sure he knows Partridge is Rj because he works for him. But the reaction is key GO BACK and watch that scene again and pay attention to Bertrum. He then claims to have slightly known Partridge. But if he slightly knew him he wouldn't have a reaction like he did. Very suspicious in my opinion. I think Bret Partridge will be back. The first responders on scene likely work for Rj like Sheridan mite and falsely confirmed Partridge being DOA. Besides the killer in red dragon faked his death and came back later in the movie. Just a theory
