Okay, so who wants to help me solve the mystery of the board behind Rigsby in the promo for The Great Red Dragon? We see pictures of McAllister, Haffner, and Stiles, and Rigsby points to them as he says: "Red John planted the bomb to kill Jane and the other suspects." We know that Bertram and Smith are still alive, as they are on the guest list for the next couple of episodes. Yet the promo says it is down to three suspects? Three suspects are on the "dead" board, so if Bertram and Smith are the only ones left, who is the third suspect?
Also of interest: There is a picture of the crime scene (bottom right of the board) and three yellow arrows probably pointing to the three dead suspects (or what remains of them.)
But here is the thing I am most curious about: The image to the left of the crime scene with red, blue, and yellow marks. We can also see the layout of the room where the explosion occurred. I can see that some of the marks are labeled as "DNA" but I'm trying to decode what the different colors mean..who is alive and who is dead? Anyone want to help me figure this out? I think it could be a big clue.
