Story : A judge, a housewife, and an attorney are all killed by toy-like devices. While searching for the victims' possible connection, Chase and August discover that all three were involved in a court case years earlier in which a woman, working in a college laboratory, was killed in an explosion set off by a radical activist. At the conclusion of the trial, the killer was set free. Afterwards, the woman's husband, Karl Shipman, set out for his own revenge. After killing the man who killed his wife, Shipman was arrested and sent to prison for life. But Shipman wasn't finished with avenging his wife's death yet, and gave the orders for murders from prison.
