SEASON 4, EPISODE 402 - A 2004 case involving the disappearance of a female Iraqi war veteran, Dana Tucker (Lesley Fera), is reopened when her high-tech titanium prosthetic arm is found in a river. When Dana returned from the war after fighting for 93 days, she was not the same. She returned home as a hero to the community--but not to her fellow soldier's widow, who is the prime suspect in Dana's disappearance. Meanwhile, Scotty visits his brother, Mike (recurring guest star Nestor Carbonell), regarding an ongoing child molestation investigation.
