In the season finale, Detectives Goren and Eames suspect an imprisoned white supremacist is behind the shootings of a judge's family, but their investigation widens when an appellate judge is later murdered -- and other recent jurist slayings out West are tied to an embittered man who seeks revenge for controversial judicial decisions. Working with a few faint clues, the detectives' search for a vagabond father with child custody issues -- and a good rifle aim - who might be using his teenaged son to help him carry out his crimes.
