She would have killed him in self defense if she hadn’t already killed him by accident? Or was it the other way around? I’m so confused.
“What I meant was I grabbed the gun and pointed it at him to get him to stop. I pointed it at him in self-defense. But I wasn’t going to kill him - I could never do something like that. I just wanted him to stop. But then he grabbed the gun, and it just went off. It was an accident - I just wanted him to stop beating me! I didn’t want him to die!!”
(That would be my “explanation” to the judge anyways.)
Never speak to the cops before talking to a lawyer. People think that if they deny any wrongdoing, they didn't hurt themselves. But once you tell a story, you're stuck with it.
