In People v. Quintero (2006) 135 Cal.App.4th 1152, 1163, the defendant initially attacked the victim's head, using deliberate uppercut motions to slash his face and holding him by the hair, and stopped his attack once he had severely maimed the victim's face.
The injuries to the victim's arms and hands occurred as the victim tried to protect his face. (Ibid.)
The court concluded that from these facts, the jury could conclude that the attack was guided by the specific intent of inflicting serious injury on the victim's face and head. (Ibid.)
