Ray Haffner was the lead agent of another team in the Homicide division of the CBI. After the sting operation that resulted in the death of Craig O'Laughlin, Cho, Van Pelt and Jane were temporarily assigned to his team. He later left the CBI to for a private security firm, and repeatedly tried to get Lisbon to join him. He was a member of Vizualize, and the cult was his main client. Jane considered him one of the seven Red John suspects. He was killed by the bombs set by Red John Thomas McAllister.
