There's a difference between permanent disfigurement and death. The crime he is charged with is assault with a deadly weapon. Assault is defined as the threat or intent to cause bodily injury to another. Clearly, he is guilty of assault. However, I am unaware of anyone who ever died from having a venti coffee spilled or thrown at them. (Now if it were a mega venti, I might agree with the charge.)
If he had lunged at her with a knife or a baseball bat, the charge would be valid. But in this case, I think he is merely guilty of assault.
