What is the test for determining whether a victim suffered great bodily injury?

It is a question of fact for the jury to determine whether a victim suffered great bodily injury. (People v. Escobar (1992) 3 Cal.4th 740, 750.) This is not a question of law. (People v. Cross (2008) 45 Cal.4th 58, 64.) On appeal, if sufficient evidence exists to sustain the jury's finding, the appellate court must accept it even if the circumstances might reasonably point to a contrary finding. (People v. Escobar, supra, 3 Cal.4th at p. 750.)
