who kills agent stahl on sons of anarchy
June Stahl In the finale of Season 3, she exposes Jax's deal to the club thinking they would kill him. Her motivation for doing so seems to have been malicious. However, Jax was aware that she could not be trusted and had already informed the other members of the club. This led ultimately to Opie, with the help of Unser, targeting Agent Stahl in retribution for her role in the death of his wife, Donna. During this confrontation Stahl breaks down crying and begs Opie for her life, to which Opie responds, "This is what she felt." He then shoots Stahl in the back of the head with a MAC-10, instantly killing her. After this, Chibs Telford rigs the scene to look as if the real IRA murdered Stahl and Jimmy O'Phelan.
