Brenan Hefner was the corrupt port commissioner of Oakland and an antagonist in Season 1. He was responsible for Michael McKeavey's death, having McKeavey beaten and left for dead after a deal went bad. Cameron Hayes was supposed to kill Hefner but, because he was shot, Jax, Bobby and Opie ended up having to do it. Clay told Bobby to make sure Opie killed Hefner (to prove Opie's commitment to the club) but, when the moment came and Opie froze up, Bobby quickly stepped in and gunned Hefner down himself. Eviqua Michaels witnessed the murder and later identified Bobby as the shooter.
