The Road Home

S4 E18: After briefly looking for an 18-year-old, the team members realize 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 the time of his disappearance and a junkie who had recently slashed Matt's arm while burglarizing his apartment. Meanwhile, a concerned Samantha tries to find the underlying cause of Martin's recent tardiness and explosive temper.
