In Johnson v. County of Ventura (1994) 29 Cal.App.4th 1400, the plaintiffs were outside a residence when a mentally disturbed person who had wandered away from the hospital, entered and stabbed the victim. The plaintiffs went inside soon after and witnessed the victim suffering. The plaintiffs failed to show that they were within the class of bystanders who could recover for negligent infliction of emotional distress: "Crediting appellants' theory would blur if not obliterate the bright line rule established by our Supreme Court." (Johnson v. County of Ventura, supra, 29 Cal.App.4th 1400, 1405.)
