Tara became pregnant in Chicago, but had an abortion at six weeks .

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 . 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 .
