S5, E6: In the landmark 100th episode of "Without a Trace," the team searches for a family man, Aaron Gibbs (ERIK LA SALLE - "ER," "One Hour Photo"), who has been emotionally haunted and financially harmed by living through and being displaced by Hurricane Katrina. Aaron's wife, Sherise (LISA GAY HAMILTON - "The Practice," "The Sum of All Fears"), tells the investigators that she last saw Aaron the previous morning when he left their Queens motel room. Supposedly, Aaron had gotten a temporary construction job in New Jersey after being fired from a construction job with his cousin, Chuck Barr (MICHAEL BEACH - "Third Watch," "ER"). But the team learns that Aaron, whose truck was found abandoned and burned, actually quit his cousin's job and lied about having found work in New Jersey. Wondering what else Aaron may have been hiding from his wife, the agents entertain theories of foul play and suicide, as well as the possibility that Aaron chose to run away from his mounting financial woes.
