Ari's wave of terror which had started when he invaded the NCIS morgue, triggering a hostage situation and had continued on for nearly two years finally came to a permanent end when he was ultimately killed in a confrontation with Gibbs and Ari's fellow Mossad Officer/half-sister Ziva David in September 2005.
Ultimately, Special Agent Leroy Jethro Gibbs arrived in the morgue per Ari's request, carrying a box of the terrorist's effects, but revealed that Ari's true object -- the smallpox -- had already been confiscated. Ari was impressed with Gibbs's marksmanship for shooting the terrorist from such a distance, and offered him a chance to kill him. Gibbs took it, but was shot in the left shoulder instead and collapsed to the ground, drifting in out and of consciousness. The gunshot wound was a through and through and Gibbs's left arm was left wounded in the process. However in the ensuing invasion of Autopsy, Ari escaped by shooting two H.R.T agents, killing one while the other survived and while disguised as an H.R.T agent, managed to flee NCIS.
Gibbs was later seen in his basement, his left arm in a sling and then proceeded to shoot a picture of Ari and it was shown that the rounds from his gun had hit the photograph dead center, suggesting that Gibbs now sought to kill Ari.
In early May 2005, while on assignment with the FBI to uncover an Al-Qaeda cell in Washington D.C. which he was running, one of Ari's men from the cell broke contact and disguised as a Virigina State Police Officer killed two Navy officers.
Knowing that NCIS would be called to the crime scene, Ari and the group planted a bomb on the car in order to kill members of Gibbs's team. The bomb went off, but no-one was killed thanks to the fact that DiNozzo had noticed it after Kate had kicked him onto the ground and had acted quickly, thus saving the lives of himself, Kate and McGee although the car and the two victims were destroyed or rather burnt beyond any recognition, forcing Ducky and Jimmy to use dental records to get a positive identification on the two bodies.
Shortly thereafter, Ari attempted to kill Gibbs by planting a bomb in a coffee shop. Gibbs spotted the device which had been hidden underneath a table at the last second and was successful in throwing the device in question into a dumpster before it exploded seconds later.
Unfortunately, the celebrations were short-lived as tragedy struck when Kate, having recovered after taking a bullet originally meant for Gibbs died after she was shot in the head, the brutal force and impact of the bullet killing her instantly while also severing and destroying her brain upon impact.
Several hours after Todd's murder, Ari attempted to kill Abigail Sciuto in her lab, but missed the shot thanks to DiNozzo's quick actions. Ari then spent the next two days leading Gibbs and his team on a wild goose chase throughout the city.
As he raised the rifle, however, he was shot, dying instantly as a result. It was later revealed that Ziva who had been listening from the doorway of Gibbs's basement the entire time finally realized that Ari was a rogue and a monster and she decided that she must kill him.
Likewise, Gibbs could not credit Ari's belief that Eli deliberately had Ari's mother killed, just to further his own plans for Ari. Partly this may have been explicable by his distrust of Ari, but also because he could not believe any man would so callously use his own family for the sake of a mission.
Eli, by contrast, is obsessed with his mission of protecting his country, so much that he has raised his own children to be killers, and engaged in various underhanded schemes to ensure their continuing loyalty to him and to Israel. After getting a glimpse of these methods, it appears that Gibbs begins to believe Eli is as ruthless as Ari described.
Gibbs's official report to NCIS stated that he, not Ziva, had killed Ari. The same report was passed on to Mossad, and Gibbs and Ziva kept the actual encounter details a secret, presumably to shield Ziva from any future accusations against her.
However, four years after Ari's death, NCIS Director Leon Vance revealed that Eli had actually become aware of Ari's treachery, and had ordered Ziva to kill him, both to dispose of a rogue Mossad agent and to earn Gibbs's trust.
A few months after that, Gibbs confronted Ziva. She admitted that she had been ordered to kill Ari, but had believed him innocent, and was going to sneak him out of the country instead, until she heard his confession in Gibbs's basement. She swore that when she shot Ari (who was, after all, her own brother), she was not blindly following Eli's orders, but doing it to save Gibbs. Gibbs appeared to accept this.
Despite being dead, Ari reappeared in the diner in which Gibbs's subconscious presented various characters of Gibbs's past, along with a few possible alternate realities. In the diner, Ari was seen playing a game of chess with Leon Vance. It was shown that a different chain of events would have been possible, with Ari failing to deliver the one fatal shot that would kill Caitlin Todd, because his scope was spotted by Gibbs and air support soon zeroed in on Ari's position, forcing him to flee.
Russian terrorist Sergei Mishnev, a friend of Ari's embarked on a campaign of revenge against Gibbs, Mishnev believing that Gibbs was the one responsible for killing Ari. It was later revealed that Mishnev was more than an associate of Ari Haswari: Mishnev also happened to be Ari's half-brother which had in turned triggered Mishnev's desire for revenge against Gibbs.
In "Under Covers" (S3E08), contract killer Marcos Siazon (Eric Steinberg) and his henchman Henry Spivey (Matthew Kaminsky) are both armed with suppressed Beretta 92FS Inox pistols. Later Ziva (Cote de Pablo) relieves Siazon of his Inox and carries it as the team rushes to Tony's rescue.
Gibbs (Mark Harmon) carries a Smith & Wesson Model 37 snub nose revolver with a black finish in an ankle holster as his backup weapon. In "Mind Games" (S3E03), he uses it to threaten sadistic serial killer Kyle Boone (Christopher Shyer). In "Probie" (S3E10), he gives the revolver to McGee, whose weapon has been temporarily confiscated, to back Gibbs up as they go to question a suspect.
In "Mind Games" (S3E03), troopers with the Virginia State Police carry the Remington 870 while escorting serial killer Kyle Boone (Christopher Shyer). In "Ravenous" (S3E17), a Remington 870 Police Magnum Riot shotgun is used by Gibbs as the team hunts a fugitive in the woods.
The onslaught on environmental activists in RondÃnia and across Brazil predates the administration of President Jair Bolsonaro, which came to power at the start of 2019. Many cases from earlier remain unresolved, such as the killing of Indigenous leader and activist Manoel Quintino da Silva Kaxarari in 2017, and the murder of human rights activist Nilce de Souza MagalhÃes in 2016; the alleged perpetrator who confessed to killing Nilce escaped from jail shortly after his arrest.
Authorities in Lake County say this murder investigation was the strangest one they've ever seen. A man faked his own death by killing another man and then assumed the dead man's identity before taking his own life.
Ari Squire killed himself in a Missouri motel room after police had learned the truth. The 40-year-old killed and assumed the identity of a 20-year-old Arlington Heights man in an elaborate scheme that police say was about money. The possible motive was to collect on a $5 million life insurance policy.

As the team attempts to deal with Kate's death, Gibbs clashes with the new NCIS director, who believes that Ari Haswari was not the one responsible for firing the bullet that killed Agent Todd. Ziva David, Ari's Mossad control officer, sides with the director, and causes problems when she arrives in the NCIS office. However, Ziva's motives for defending Ari become murky, when she communicates with him and doesn't tell anyone in the NCIS office. Ari kidnaps Ducky to divert the team's attention away from Ziva.
