its simple. look at the seven suspects, and look at the facts, he is a mid age man, there for we eliminate the old ones, and we have ...kirkland , hafftner, smith and partdidge, the last one is dead so we have 3, red john does have a firm body but not very muscle, so smith is out for being fat, we have 2..Kirkland kills Jason Lennon by injecting him with an empty syringe,
causing an air embolus which stopped his heart. He asked Lennon if he
recognized him. Lennon said NOOO. And Kirkland said he was giving him a
peaceful death, lennon knew red john and he never gives peaceful death to nobody.
now we just have one, the one and only RAY HAFFNER
