WHILE SEARCHING FOR A MISSING TEEN-AGED BIKE MESSENGER, SAMANTHA TRIES TO UNCOVER WHAT'S REALLY WRONG WITH MARTIN, ON "WITHOUT A TRACE," THURSDAY, MARCH 30

"The Road Home" -- As the team searches for a missing 15-year-old bike messenger, Samantha tries to figure out why Martin's behavior has been so erratic, on WITHOUT A TRACE, Thursday, March 30 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Chad Lowe directed the episode written by David Mongan.

After briefly looking for 18-year-old Brandon, the team realizes that the real missing person is 15-year-old Matt Jameson who was impersonating his former basketball league pal in order to work as a messenger and apprentice locksmith. The team's suspects include a fellow messenger who was found with some of Matt's possessions, a tattooed man who was seen with Matt around his disappearance and a junkie who had recently slashed Matt's arm while burglarizing his apartment. Meanwhile, a concerned Samantha tries to get to the bottom of Martin's sudden tardiness and explosive temper.
