The agents of NCIS: Los Angeles are about to be worked out the final cases. The network made the announcement late on Friday that the 14th season of the long-running spinoff of NCIS will end in May. The crime drama will air its 322nd episode and series finale on May 14. It reached the 300-episode mark late in season 13.

“For 14 seasons, NCIS: Los Angeles has been a stalwart of our lineup with characters who were a joy to watch,” CBS Entertainment president Amy Reisenbach said in a statement. “It’s no surprise this show succeeded as a global franchise. From day one, the cast, producers and crew were amazing network/studios partners, and their teamwork, talent and spirit vividly came through on the screen. We are so grateful for the collaboration and remarkable run of these treasured members of our CBS family, and plan to give them the big sendoff they and their fans deserve.”

NCIS: Los Angeles premiered in 2009 and ranked among the top 10 network shows in terms of total viewers in its first five seasons. Despite changing time periods a half-dozen times, it has never fallen below the 30th spot in terms of viewers, where it currently sits this season.

“I want to thank both the network and [CBS] Studios for their partnership and support over the years; [series creator] Shane Brennan for giving us such a great playground; and my partners John P. Kousakis, Frank Military, Kyle Harimoto and Andrew Bartels for their tireless efforts and collaboration episode after episode,” said showrunner R. Scott Gemmill. “Our crew has grown to be a true family, and their hard work and dedication has been fundamental to our success year after year. My deepest gratitude to the cast members, who have brought our characters to life with their impassioned performances — thank you for your talent, professionalism and continuous enthusiasm. And to our loyal viewers who loved our characters and followed their journeys, thank you. We look forward to delivering an end to the series that is both satisfying and does justice to these beloved characters.”

LL Cool J, Chris O’Donnell, Linda Hunt, Daniela Ruah, Eric Christian Olsen, Medalion Rahimi, Caleb Castille, and Gerald McRaney are among the cast members of the series. LL Cool J, O’Donnell, Hunt, Ruah, and Olsen have been in the same group for nearly the entire run; Olsen appeared once more in the first season before becoming a regular in the second.

The CBS Studios series is executive produced by Gemmill alongside Kousakis, Military, Harimoto, Bartels, and Brennan.

NCIS: Los Angeles, which began as a spinoff of NCIS and is itself a spinoff of JAG, is the franchise’s second-longest-running show, trailing only the parent show, which is currently in its 20th season. NCIS: New Orleans ran for seven seasons, and NCIS: Hawai’i is in its second.
