The “NCIS”-verse was unexpectedly vaulted into TV tragedy with the taking pictures dying of Director Leon Vance (Rocky Carroll) throughout the March 24 five hundredth episode, “All Good Things.”
The boxing fanatic Vance is so surreally shocked by his personal dying that his beloved colleague, the young Donald “Ducky” Mallard (Adam Campbell), visits from heaven to ease Vance into acceptance and ship him towards the sunshine. Carroll, who will proceed to direct “NCIS” episodes, was also stunned when he learned about his character’s fate after 18 seasons.
Yet, throughout the CBS procedural’s ongoing 23-season run, “NCIS” has featured heartbreaking deaths earlier than.
“There’s always been an element that you don’t know what’s going to happen on this show,” says Sean Carroll, who has survived as Special Agent Timothy McGee since Season 1. “The ‘NCIS’ world is still dangerous with very high stakes.”
Here are six “NCIS” TV deaths which have develop into much more heartbreaking over time.
Special Agent Caitlin Todd’s surprising Season 2 dying set the ‘NCIS’ tone
The 2005 Season 2 finale dying of Special Agent Caitlin “Kate” Todd (Sasha Alexander) set an early tone for “NCIS.” In the final seconds of the finale, Ari Haswari (Rudolf Martin) shoots Todd useless – still the collection’ most surprising second over the a long time.
“This is the show that Sasha Alexander, who was the female lead for two seasons, took a bullet and died in close-up in the finale,” says Carroll. “That was before ‘Game of Thrones’ when people got used to seeing the leads go away.”
It was Alexander’s decision to leave “NCIS,” going on to star as medical examiner Maura Isles on the TNT crime drama “Rizzoli & Isles” for seven seasons and appearing on CBS’s “FBI” in 2019.
Gibbs’ mentor Mike Franks died in Season 8 action
Former NIS leader Mike Franks (Muse Watson) was Leroy Jethro Gibbs (Mark Harmon) beloved mentor. Called in from Mexico retirement in Season 3, Franks called NCIS living legend Gibbs “Probie” from the coaching days. But in Season 8’s “Swan Song,” Franks was stabbed within the rain attempting to apprehend the infamous Port to Port Killer (Kerr Smith). Even in dying, Franks appeared in Gibbs’ creativeness to give clever counsel.

Season 10 featured a stunning double-tragedy with the shooting death of Director Vance’s wife, Jackie (Paula Newsome), and Mossad Director Eli David (Michael Nouri), the father (and last living family member) of Special Agent Ziva David (Cote de Pablo). An unknown assailant shoots up the Vances’ house during a Shabbat meal, before killing himself with a cyanide cigarette. Ziva breaks down sobbing, cradling her deceased father. Critically wounded, Jackie dies later in surgery. To add insult to emotional injury, Gibbs and his “NCIS” crew are suspected of being part of the deadly plot.
