For those who believe your suspect could still be Red John: Someone as careful and calculating as RJ could have
planned/planted DNA or faked evidence if tyger tyger is really as deep
as they make it sound. Confirmation of the deaths
from the blast is brought to light and accepted as fact during the show before
mistrust in other law enforcement is placed. Forensics and all 'facts' that are not in front of us are up for debate. I do, however think that Partidge is dead. It makes no sense that CBI agent Cho would somehow not recognize a former colleague or look at his face to be absolutely certain it's him. Especially when there is so much mistrust going around. I give the writers more credit than that. That being said, the "DNA evidence" is not anything concrete that we can trust. This leaves Mcallister, Haffner and Stiles all available to possibly be alive. It is a fair guess assume that Patrick Jane isn't convinced that RJ is Bertram. Bertram is an evil man so PJ doesn't care about the pressures or situation Bertram is in now with the finger pointed at him, but he isn't RJ. Patrick wants RJ all to himself. That being said, I have no idea who RJ is but my hat is off to the creator for making such an interesting finale and finally bring this wonderful mystery to a satisfying close. Right until the very end.
