NCIS: New Orleans Exclusive: LaSalle's Car Knowledge Leads to a Big Clue

NCIS: New Orleans airs its fall finale Tuesday and it's going out with a bang.

That's literally, unfortunately, as Agents Pride (Scott Bakula), LaSalle (Lucas Black) and Percy (Shalita Grant) are called to investigate the fatal crash of a Marine corporal who's an amateur racecar driver. Thanks to LaSalle's experience tracking cars, he has insight that leads to the first clue in the case.

And if you pay close attention at the outset, you'll hear the new father apologizing for something -- a personal issue perhaps? -- that'll be fully explained in Tuesday's episode, too.

NCIS: New Orleans airs Tuesdays at 10/9c on CBS.
