Terry Kinney Hunting Red John On The Mentalist

Terry Kinney has signed for seven episodes in a new recurring role on CBS’ The Mentalist. Kinney will play Agent Sam Bosco, a seemingly flat-footed policeman with a deceptively sharp intelligence. Bosco leads the California Bureau of Investigation’s Serial Crimes Unit and is brought in to assist in cracking the case of the elusive Red John serial killer, whose victims include the wife and daughter of CBI consultant Patrick Jane (Simon Baker).

Bosco and Jane are bound to clash as Bosco’s by-the-book approach is a constant irritation to Jane, while Bosco hates Jane’s unorthodox methods and is determined to oust him from the CBI. Bosco served as Lisbon’s mentor as she was coming up through the ranks, during which they had a relationship and the two share a deep, dark secret.

The Mentalist returns to CBS for a second season September 24 10:00 PM/ET.
