If Brett Partridge is dead and he isnt RJ and i say IF because this photo here from s02e08 http://thementalist.wikia.com/wiki/Forum:Red_John_Theories?file=Vlcsnap-2012-10-09-23h24m43s165.png tells me that Partridge is either Red John or a very faithful servant of RJ who accepts to beat till death by real RJ just to misslead Lisbon for RJ to catch her ,then there is only one option.Sherrif Thomas McCallister.First of all he and Partridge are the only ones from the list of 7 who appeared in season 1. Second Dumar(s01e23) was a sherrif more than 10 years as he says.He is too young dont you think?So someone else who is also a Sherrif put him in that place.In s01e02 where McCallister appears we have the same thing with S03e24 where the fake RJ revealed.And of course RJ isnt gonna be Gale Bertram as many of you suggest..Come on you saw that dialogue between him, PJ and Lisbon...Way too obvious!!!!I really cant wait for the next episodes !!!
