I think Michael Kirkland is still alive I'm not saying he's RJ but I think he did what Hightower is doing faked her death and disappeared maybe he got his acted together and realized he messed up. It's like loralie I think RJ would have killed Michael and made it obvious , I think Patrick will research about Michael and find him to get information about Red John and I think Patrick owes Bob at least finding out what did happen to his brother, RIP BOB
