In Keck v. Jackson, 122 Ariz. 114, 593 P.2d 668 (1979), the court enumerated three factors that must be established to recover for emotional distress from witnessing harm to another: (1) "the shock or mental anguish of the plaintiff must be manifested as a physical injury"; (2) "the emotional distress must result from witnessing an injury to a person with whom the plaintiff has a close personal relationship, either by consanguinity or otherwise"; (3) "the plaintiff/bystander must himself have been in the zone of danger so that the negligent defendant created an unreasonable risk of bodily harm to him." Id. at 115-16, 593 P.2d at 669-70.
