Two Families

S2 E21: The team searches for Mark Wilson (J.K. Simmons - "Oz," "Law & Order"), who disappeared while trying to prove the innocence of his death-row inmate son, Ricky (Michael Goorjian), scheduled to die in two days. The father has devoted the past 11 years trying to prove that Ricky was wrongly convicted of killing a young married couple in front of their 5-year-old daughter during a convenience story robbery. While realizing that the despondent dad could have brought harm upon himself, the team members--who question if Mark is right about Ricky's innocence--wonder whether or not Mark's investigation was the cause of his disappearance.
