i was not sure before but now i am. it is clear that the producers were not gonna let us now who is the real red john among those seven suspects, so when i saw that Virgil Minelli wasnt on the list, it made me reinforce my theory. he is someone unexpected, he fits the physical conditions described, he has appeared from the beggining of the show, since season 1, and he suddenly resigned the cbi. jason lennon, who was a friend of RJ, liked to fish, and Virgil has also been seen fishing, 

Red John is VIRGIL MINELLI
