I don't accuse Stiles (even though he does seem really likely) but I'm not able to post without accusing anyone
Just a thought, not really accusing anyone. Seeing next week's episode promo, if Jane is going to search each and everyone of the suspects for a tattoo, and supposing only Red John has that tattoo, then the mystery would be solved by the next episode. But seeing that other episodes focus on the remaining suspects, I'm thinking that maybe some or most of the suspects have that tattoo because they're part of they Tyger Tyger conspiracy, which is why Jane won't be able to tell who's Red John and the list will be narrowed down.
