Even the name of Bob Kirkland is deleted from the list because of his death, I believed that his twin brother Michael still alive and we can say Kirkland's picture is on the list. In season 5 episode 18, Kirkland killed Red John's fellow and he exactly asked this "Have you seen me before?" so far it sounded meaningless but we learned 6x4 Kirkland has a twin who knows Red John. And he figured out Michael is alive, he is in doubt in Red John uses his brother for his dirty jobs. That is why he asks all Red John suspects "Do you recognize me?". Up to present, we must have seen Michael in some scenes but we did not realize for now. We thought him Bob.
