Shootout In Decker's Diner

The Shootout In Decker's Diner was an incident that occurred in May 2008 in an abandoned diner belonging to retired NCIS 
Special Agent William Decker which was located in the Mojave Desert in California with the gunfight taking place between NCIS Director Jennifer Shepard and four unnamed assassins sent by an old enemy of Jenny's.
The gunfight eventually resulted in the deaths of all four assassins as well as Jenny herself due to the amount of blood loss caused by the injuries she had sustained during the fight.
==Prelude==
In 1999 in Paris, France, Jenny, her lover/partner, future NCIS Special Agent Leroy Jethro Gibbs and Decker participated in a mission in Paris with the assignment being to kill Russian arms dealer Anatoly Zhukov and his fiancé Svetlana Chernitskaya.
While Gibbs succeeded in killing Zhukov in a street in Paris, Jenny hesitated when it came to killing Svetlana before making the decision to let Svetlana go.
Nine years later, in May 2008, Decker's role in the Paris operation was exposed by an unknown source. 
As such, a man under with the alias, Viggo Drantyev and his three men arrived in Los Angeles where they captured Decker before torturing him.
Decker refused to give up any information concerning the operation and instead gave them a code word; Oshimaida, while knowing full-well that he was about to die.
Having gotten nothing but a simple codename, Drantyev and his men then killed Decker (making it look like a simple heart attack) before fleeing the scene.
Decker's remains were later found a few hours later with the local Medical Examiner determining that Decker had died of a heart attack while the main NCIS branch in Washington D.C. was informed of Decker's death.
Shepard who had worked with Decker later flew out to Los Angeles to attend Decker's funeral with NCIS/Mossad Liaison Officer Ziva David and NCIS Senior Special Agent Anthony DiNozzo coming along with her, both having assigned to serve as Shepard's own bodyguards but what they did not know was that Jenny had secretly contacted Gibbs's mentor and former NIS/NCIS Special Agent, Michael Franks for help, Jenny having come to the conclusion that Decker's death was not of natural causes.
Upon seeing Drantyev asking for a man named "Oshimaida", Jenny panicked and responded by taking some photographs of Drantyev getting into an SUV with an unknown blonde-haired woman who was actually Svetlana.
Realizing that she needed to settle this once and for all, Jenny gave both Tony and Ziva the day-off before heading off to a hotel where she met Franks and working together to pursue leads, the two soon found themselves in an abandoned diner in the Californian desert.
Back in Los Angeles, Ziva and Tony grew increasingly concerned over Jenny's whereabouts and attempted to get her location, only for Jenny to constantly ignore their warnings as Jenny chose to handle this crisis herself.
With no options, Ziva and Tony enlisted the help of their colleague, NCIS Special Agent Timothy McGee who eventually sent them the location.
==The Crisis==
Eventually, the four assassins including Viggo who had killed Decker and later, Decker's girlfriend, Sasha Gordon who presumably gave up the existence of the diner before she was murdered found the abandoned diner and arrived there, preparing to invade.
This occurred while Jenny was inside the diner and Franks was outside, getting some water.
The four assassins then split into two separate teams and attempted to strike, only for Jenny to fatally shoot all four men although she sustained wounds in the process.
A while later, with all the four gunmen dead, Jenny herself succumbed to the wounds and died, presumably from blood loss while Franks arrived back and shot the four men to ensure that they were all dead before he too fled, taking the car he and Jenny had used to travel to the diner in the first place.
A few hours later, Tony and Ziva finally arrived and after checking the diner for any further threats, found the bodies of the four men as well as Jenny inside. Tony initially checked for a pulse but was dismayed to realize Jenny was dead, leaving the two stunned. 
Following the grim discovery, the diner was sealed off and processed by Vance who had arrived after being called by the SECNAV with Tony and Ziva helping him while the remains of the four gunmen and Jenny herself were later shipped back to NCIS HQ at the Navy Yard in Washington D.C. where the autopsies on the bodies were performed by NCIS Medical Examiner, Dr. Donald Mallard and his assistant, James Palmer.
As Tony and Ziva as well as the rest of the team struggled to come to terms with the tragedy, Tony personally blaming himself for not following Ziva's belief that something was amiss, the case continued with NCIS Forensic Scientist Abigail Sciuto and McGee soon discovering that the woman Jenny had photographed was "Natasha Lenkov" although they discovered that her real name was Svetlana Chernitskaya.
Having discovered the truth himself, Gibbs later went off the grid and lured Svetlana to Jenny's house where Gibbs learnt that Jenny hadn't been able to kill Svetlana during the mission in Paris but just when Svetlana was about to kill him, she was shot in the back by Franks who had been lying in wait with the shot also ending Svetlana's life.
After a while, the two men made the decision to burn down Jenny's mansion and claim that Svetlana's remains were actually Jenny's so that they could cover up the death and avoid the fallout that would ensure if the true circumstances behind Jenny's death were revealed to the public while presumably ensuring that Jenny had left a positive legacy during her time as NCIS Director and presumably as an NCIS Special Agent.
==Aftermath==
A few days later, Jenny's funeral was held and her remains buried with the NCIS Major Case Response Team including Ducky, Abby and Palmer all attending.
Vance, originally the Assistant Director for NCIS was later promoted to NCIS Director, replacing Jenny on a permanent basis with his first order of business being to reassign Tony, McGee and Ziva and give Gibbs a new team composed of three current NCIS agents: Michelle Lee, Daniel Keating and Brent Langer which would lead to two mole hunts conducted over 2009.
In November 2010, Gibbs discovered that former NCIS agent Riley McCallister was the person responsible for arranging both Decker and Jenny's murders, McCallister having hired Svetlana and Viggo as well as a team of hit-men to kill them with McCallister hoping that the fallout would see him become NCIS Director. McCallister would also later reveal to have been involved in the Paris Mission where Gibbs killed Anatoly Zhukov whose name was to how Gibbs found out about McCallister whose also responsible for Leon Vance's mission in Amsterdam.
Seven years later, in September 2014, several classified NCIS files, including the case file for the shootout ended up being stolen by the Russian/Palestinian terrorist Sergei Mishnev via a computer virus unleashed on the NCIS servers.
Several months later, Mishnev proceeded to use the newly-gained knowledge to his advantage where he, after luring five DOD personnel (four men, one woman) to a fake tax firm and having them lined up and shot, proceeded to line up the bodies in a nearby diner in such a way that mirrored the events of the shootout which occurred during the Season 12; Check (episode).
A year later, after Mishnev had gained access to the files, in October 2015, Operations Manager Henrietta Lange would bring up the shootout during a conversation with DiNozzo in the NCIS: Los Angeles Season 7 episode, "Blame It on Rio".
