Agent Joshua "Josh" Kohn is a fictional character from the FX television series Sons of Anarchy, played by Jay Karnes. He served as one of the main antagonists on the show's first season and is an agent for the Bureau of Alcohol, Tobacco, Firearms and Explosives. The Santa Rosa Press Democrat called the character "terrifically creepy."
Kohn was a federal Bureau of Alcohol, Tobacco, Firearms and Explosives agent from Chicago, Illinois. He dated Tara Knowles, but they split and she returned to her home town of Charming, California to escape him. She also filed a restraining order against him. Tara was pregnant with his child but she had it aborted at six weeks. He then became obsessed with her and tracked her down.
Josh Kohn travelled to Charming to look for Tara, and pretended to be investigating a local motorcycle gang, the Sons of Anarchy, as his reason for being there. He discovered that she had previously been in a relationship with Jax Teller, the Vice-President of the Sons of Anarchy, and began following him and taking photographs. He trailed him out to Indian Hills, Nevada and photographed him having sex with a woman. He then sent these photos to Tara. He also began stalking Tara and phoning her frequently. When Tara told Jax about this, he threatened to kill him if he went near Tara again. Then he defeated on himself. He also reported him to the police, who in turn informed the ATF. Upon learning that Kohn has threatened Abel and the authorities have not yet apprehended him, Jax went and hunted for him himself. He found him at the local barber shop, and a brawl ensued with Jax emerging the victor. Kohn was then arrested for breaching his restraining order on Tara. He was told that his career as an ATF agent was over and taken to the airport in a police car, with instructions to return to Chicago. He returned to Charming in the dead of night, however, and broke into Tara's home. He then attempted to rape her, but she grabbed his pistol and shot him in the stomach. As he lay bleeding, she called Jax and told him to come over and help. Shortly after arriving at her house, Jax took the gun from Tara and shot Kohn in the head. Jax later took his body to the desert and burned it.
Kohn is mentioned to have been declared MIA by the ATF, having failed to arrive in Chicago. Stahl, however, had private suspicions that SAMCRO murdered Kohn. These suspicions are confirmed when speaking with Jax during his time in San Jaoquin County Jail, Jax all-but-confessed to killing Kohn - he casually asks if Stahl ever heard from Kohn, remarking how dangerous it must be to be a federal agent. Stahl immediately realized Jax killed Kohn, yet she "thought (he) was too pretty to be a killer" and hinted that, once her investigation into the True IRA was over, she would look around Charming for Kohn's shallow grave.
