If i remember the spoiler correctly, it was an accident. Technically Nick did shoot her brother while they were wrestling the pistol away from each other (I don’t know why they were wrestling—maybe because they’re enemies?), then the gun goes off & strikes the brother; he dies.
Who really killed the brother? I’m thinking the dad.
