The Mentalist Episode 1.11 Red John's Friends

An inmate, serving twenty-five to life for murdering his family housekeeper's daughter, contacts Jane about having information on Red John that he'll reveal if Jane will prove his innocence. Minelli disproves of reopening the case, but Jane needs to find out the truth so he quits CBI, and the rest of the team takes a week's suspension to help him. After delving into the Renfrew family affairs, Jane makes a disturbing discovery that Jared's mother committed the murder and framed Jared, after learning he was in love with the housekeeper's daughter and that the girl was her husband's child from an affair. Following the mother's confession, Jared is released, but slips from sight before revealing anything about Red John. When CBI hunts him down in Mexico, they find Red John has gotten to him first, leaving behind only some cryptic words to the information he had.
