OKay after swaying to Ray Haffner for a brief period of time ( Jesus christ Bettyboo!). I really change my mind after I rewatch scenes of each suspect lol, I have finally settled. Okay so we are told by people who have seen the episode Legit, that the clues do add up to Red John. That means that RH description is correct. So this is why I believe that the sheriff is RJ and Yes they did spoil it for us but nevermind. Partridge, Bertram, Stiles, Kirkland and twin brother. Reede are most likely not Red John for obvious reasons...Death, arrested etc.... That leaves the two suspects Ray and the Sherrif.

First things first, I had a hard time with the description because somethings don't add up exactly but you have to use logic. I doubt that Ms R.H would get the height wrong. it's the one thing that doesn't change and she can't see so she uses touch to determine everything. It's pretty certain that that Red John is LESS than six foot. This rules out Ray Haffner who is over the 6 foot. 

The hair was the problem for me and the only problem to be honest. But as we know Hair comes and goes. The sheriff probably had the hair back in the day and it is short so I wouldn't let that throw me off too much. He has hair and it's short nevermind about the balding.

Now onto the positive things.
