THE NCIS TEAM INVESTIGATES A CASE OF IDENTITY THEFT WHEN A PETTY OFFICER IS GUNNED DOWN IN HIS CAR, ON "NCIS," TUESDAY, OCT. 18

"Switch" -- The NCIS team is called in when a Petty Officer is brutally gunned down on the freeway, on NCIS, Tuesday, Oct. 18 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Tom Wright directed the episode from a script by Gil Grant.

As the investigation unfolds, Gibbs and the team discover that the Petty Officer had been living a double life and had switched identities with a former colleague whose job of illegal transporting gives the team their first lead to the murderer. But the break in the case is short-lived when Abby uncovers a message the Petty Office left before dying that leads them in an entirely different direction.
