Attempted or frustrated murder?

One evening, a man stepped out of his home and was shot by the accused. As his two daughters rushed to his aid, the accused shot one of the girls in the abdomen. The man and his daughter were rushed to the hospital. The man fully recovered after the treatment of his gunshot wound on his right forearm. His daughter however was proclaimed dead on arrival at the hospital.

The accused was charged with murder and frustrated murder, both with the use of an unlicensed firearm. In his defense, the accused claimed that the shooting incident occurred because he had acted in self-defense. He alleged that the man, who was then armed with a gun, challenged him to a fight. The man attempted to shoot him but the shotgun jammed. The accused then tried to wrestle the gun away but during the struggle, the shotgun fired. The accused claimed he did not know if anyone was shot.
