What is the test for making a criminal threat?

A criminal threat has five elements: (1) the defendant willfully threatened to commit a crime that would result in death or great bodily injury to another person; (2) the defendant had the specific intent that the statement be taken as a threat; (3) the threat was on its face and under the circumstances " 'so unequivocal, unconditional, immediate, and specific as to convey to the person threatened, a gravity of purpose and an immediate prospect of execution of the threat' "; (4) the threat caused the victim " 'to be in sustained fear for his or her own safety or for his or her immediate family's safety' "; and (5) the victim's fear was reasonable under the circumstances.
