I said this after the first episode of this season that Brett Partridge is Red John he is a forensic specialist so he could make his death look real and I will list my other reasons.  First why did he say tyger tyger to Lisbon so far only people connected to Red john have said that.  Second he has been there since the first episode and his voice and other features match.  Third he is the only one besides Bret Stiles who hasn't really done suspicious stuff or associated with the other suspects.  What better way to throw Patrick off his game then to take himself off the list Bruno Heller said the list is real but he never said what rules can be broken with the list and faking his death would be perfect.  When the three suspects Bertram, Mcallister, and Reede are talking they said does he know I think they meant does he know Brett is alive maybe they do work for Red John.  I got a lot of people to disagree with me on this and I do think Mcallister is the only other one that makes a great suspect but I don't think Bruno Heller took us on this 8 season ride to reveal something so obvious so I'm going to stick to my theory that it is Brett Partridge and think about this he knew he was a good suspect from the start even without the list people compared his voice and the description of him so it would make sense that Bruno Heller would take him out the first episode so we would forget about him and focus so much on the others that we are blown away when we find out because we aren't even suspecting him anymore.  I know many will disagree but I won't change my mind and when it is revealed people can go back and see that it made sense. Also I really like everyone's theories on everyone it takes a lot of detailed thinking to come up with these theories I just hope you guys don't bash me too hard and see that it does make some sense that he would kill Red John off the list first episode he kept his word about the list but is still keeping us in the dark.  Thanks for reading my theory.
