The culprit seems to be a faulty parachute, but standard investigation reveals that the death might not have been an accident after all.

In his efforts to clear the commander 's record and good name, Gibbs uncovers a turf war between two rival drug gangs and a terrorist 's scheme to knock out the national power grid.

Two former shipmates who served with the deceased come under suspicion for both the murder and the theft.

As the investigation continues, it soon becomes apparent that the killer took steps to prevent the body from being identified. Gibbs quickly comes to believe that the motive for the brutal murder was identity theft and his suspicions are further confirmed when it is revealed that although a submariner is dead, no one has been reported missing, leading Gibbs to believe that an impostor is on one of the submarines. Tony, Abby, and McGee are tasked with identifying the deceased, while Gibbs and Kate are sent underwater on a submarine to vet five possible suspects, one of whom might have been responsible for the murder and to also prevent a possible sarin attack from taking place. 8 8 `` Minimum Security '' Ian Toynton Philip DeGuere, Jr. & Donald P.

Gibbs suspects CIA involvement, and the team soon find themselves tracking a rogue operative who killed the first Marine as a part of a cover - up in regards to a classified mission that ended in disaster and is now attempting to kill off the dead Marine 's partner to make sure that the investigation is wrapped up while he flees with the money the CIA previously paid in an attempt to save the two kidnapped Marines.

But unknown to Kate and the team, Jane is actually lying to Kate as she is already beginning to secretly remember her past and is probably planning something to strike back against her employers, something that might end in bloodshed not only for her but could affect Gibbs and his team as well. 11 11 `` Eye Spy '' Alan J.

McGee manages to track the tip - off to Langley, suggesting that the CIA has been spying on the base. Gibbs and Kate follow the tip - off, coming across a witness who leads the team to several possible suspects. At first the murder seems to be tied in with work the officer was involved in, but Gibbs soon begins to suspect that the motive for the death might not actually be espionage - related and that someone else might be the true killer. 12 12 `` My Other Left Foot '' Jeff Woolnough Jack Bernstein February 3, 2004 ( 2004 - 02 - 03 ) 112 12.31 When the severed leg of a marine is discovered in a dumpster, Gibbs and the team immediately run into a problem -- identifying who the leg belongs to and finding the rest of his body.

The NCIS team decide to investigate closer to home where they uncover a mother and daughter who are both guarding a deep secret. 13 13 `` One Shot, One Kill '' Peter Ellis Gil Grant February 10, 2004 ( 2004 - 02 - 10 ) 113 13.18 When an over-embellishing marine recruiter is killed, the NCIS team quickly discover that a highly intelligent and skilled sniper was behind the attack. Initially, the team believes the sniper had a grudge against the recruiter, but when a second attack occurs the investigation takes on a wider scope and as a result, the FBI are called in, bringing Gibbs into direct conflict with his old friend Fornell. After hitting several dead ends, the team realize that the killer had left a `` calling card '' in the form of a white feather at each scene and was most likely targeting recruiters in revenge for being rejected by the Corps. Hoping to lure out the killer, Gibbs dons his old Marine uniform and takes over the recruitment office with Kate as his new `` commanding officer '', while DiNozzo and the FBI team lie in wait. 14 14 `` The Good Samaritan '' Alan J.

As the team struggle to find a motive or suspects for either case, another murder occurs ; this time a naval aviator. Ducky points out that while the murders appear to follow the same modus operandi and seem to have been carried out by a serial killer, some elements are different, indicating that the murders were not carried out by the same individual which suggests that there is a copycat on the loose. A DNA sample draws suspicion onto the widow of the third victim, but she has an iron - clad alibi, leaving Gibbs and the team with a complex investigation and many loose ends to tie up. 15 15 `` Enigma '' Thomas J.

Ryan later contacts Gibbs, and explains that he has discovered a conspiracy to siphon funds out of Iraq for use on black ops while vehemently denying any responsibility. Gibbs finds himself in a delicate situation as he realizes that Ryan is mentally unstable after the latter kept mentioning a `` Lt. Cameron '', Gibbs 's former company XO who had died in his arms years ago. Gibbs later learns that Lt. Cameron is alive, but only in Ryan 's Head and is working with Ryan to stop the conspiracy. After being arrested for `` pissing off the FBI '', Gibbs, along with Fornell, set out to discover the truth behind the Colonel 's claims in a tense standoff and discover that Ryan had indeed been framed.

Preliminary investigation suggests that the petty officer was killed in the nearby parking lot, and was dressed after his death. Upon checking the victim 's room, evidence surfaces that he might have been taking financial bribes or someone else may have been blackmailing him. Gibbs suspects the victim 's co-workers of involvement in the death when their separate versions of events are too consistent. Forensic evidence links them to the scene, and they eventually confess that their coworker 's death was a result of a prank gone wrong. However, Gibbs believes that the petty officer 's death was more than just an accident. 18 18 `` UnSEALeD '' Peter Ellis Thomas L. Moran April 6, 2004 ( 2004 - 04 - 06 ) 118 10.83 A former Navy SEAL convicted of double homicide escapes from Leavenworth, resulting in Kate and McGee being assigned to protect the son and in - laws of the escaped prisoner. During the night, the SEAL breaks into the house to see his son before fleeing, leaving Todd tied to a chair and unarmed, her weapon having been taken by the SEAL as a form of protection and to be possibly used in another crime of some sort. Using her profiling skills, Kate theorizes that he may actually be innocent and had discovered the identity of the real killer while in jail. At headquarters, the team has to contend with the antagonistic defense and prosecution attorneys, one of which is Lt. Commander Faith Coleman as they review the evidence in order to find the real murderer before the SEAL delivers his own brand of justice : revenge. 19 19 `` Dead Man Talking '' Dennis Smith George Schenck & Frank Cardea April 27, 2004 ( 2004 - 04 - 27 ) 119 11.64 Special Agent Chris Pacci is brutally murdered while investigating a cold case, prompting a guilt - ridden Gibbs to step in and take over the case while attempting to find Pacci 's killer. Picking up from where Pacci left off with McGee 's assistance, the team follows the trail of millions of dollars embezzled by Navy Lt. Cmdr. Hamilton Voss ( who died before trial ), and is led to a mysterious woman named Amanda Reed ( Jamie Luner ) who seems to appear near wherever Voss has been stationed. The agents take shifts conducting a stake - out on the woman 's house, until Tony is caught raiding the mailbox. Forced to improvise, he introduces himself as a resident of the neighborhood and strikes up a conversation based on what he had heard via surveillance. This gives him a chance to get close to the suspect in order to find out more, as he goes on a successful date with her. Meanwhile, Abby makes a shocking discovery which turns the direction of the case and will give Kate something to mock Tony about for time to come. 20 20 `` Missing '' Jeff Woolnough John C.

When skeletal remains of one of the missing men is found chained to a pipe in a small sewer room, Gibbs begins to suspect the unit CO ( the only team member not dead or missing ) as a serial killer. However, when Tony vanishes while tailing the CO from the unit, the investigation takes on a more frantic pace and McGee is called back in from Norfolk to help as Gibbs and Kate work against the clock to find Tony before it is too late. Tony wakes up in a room with the missing marine. Unfortunately, their only hope of finding Tony and the missing marine alive is an uncooperative journalist. Tony and the marine escape their cell and make their way through the sewer system, and soon come across his teammates ; however, he and the marine are forced to keep moving because the killer is right behind them. The team ultimately uncovers a shocking truth about some petty matters of the EOD unit gone wrong over 12 years ago and that the survivor of the fatality was the serial killer. When Tony and the marine become cornered, the killer reveals herself, wanting revenge for what happened to her friends. It is further proved when she shots and kill 's the unit CO in front of DiNozzo 's eyes ; however, thanks to DiNozzo and the team, they save the missing marine. 21 21 `` Split Decision '' Terrence O'Hara Bob Gookin May 11, 2004 ( 2004 - 05 - 11 ) 121 11.07 As Ducky meets his new assistant, Jimmy Palmer who is replacing the injured Gerald Jackson, Gibbs and the team handle the case of a marine found impaled on a tree stump after being shot with a SMAW.

The death is initially dismissed as an equipment malfunction, but Abby discovers that the link attaching the lieutenant to his rappelling rope was made of a weaker material than factory standard, suggesting sabotage and potentially murder. Pressure is applied by the CIA for the investigation to be wrapped up within 38 hours so the operation can continue or else the entire mission, which is of national security importance, will be scrubbed. As the case goes on, Gibbs discovers that the lieutenant had a secret, and that his wife might be holding back vital information about his death.
