Facts

Kuntz and Becker had lived together for about six years and were ending a stormy relationship. After returning home and finding her belongings destroyed and the home trashed, Kuntz said Becker attacked her in the kitchen, grabbing her by the hair, shaking her, and slamming her into the stove; Becker later died from a single stab wound to the chest. Kuntz found Becker unresponsive on the porch, drove to a friend's house several miles away, and called her mother; authorities were apparently summoned by Kuntz's sister-in-law within about an hour after the stabbing. The State amended the negligent homicide charge to allege that Kuntz caused Becker's death both by stabbing him and by failing to call for medical assistance.

Issue

When a person claims she justifiably used deadly force in self-defense, does she nevertheless have a legal duty to summon aid for the wounded aggressor, and can failure to do so support criminal liability or rebut the justification defense? Also, may post-stabbing conduct be used as part of a negligent homicide charge or to challenge justification?

Rule

For criminal liability based on omission, the law must impose a duty to act and the person must be physically capable of performing it. A person who justifiably uses force to fend off an aggressor has no duty to assist the aggressor in any manner that may create a risk of bodily injury or death to herself or others, including remaining in or returning to the zone of risk; her immediate duty is self-preservation by seeking and securing safety. After safety is fully secured, a duty to summon aid may revive if the person knows the facts indicating a duty and is physically capable of acting, but criminal liability for negligent homicide may arise only if the failure to summon aid, rather than the justified use of force itself, is the cause in fact of death and the omission amounts to a gross deviation from a reasonable standard of care.

In Spokane, Nora Ellison was cornered in her apartment hallway by her former live-in partner, Devin Cross, who swung a metal flashlight at her. Nora grabbed a kitchen knife from a nearby counter, stabbed Devin once, and immediately ran out a rear exit to a neighbor's locked unit because she feared he might still be armed.

If Nora's use of force was justified, when did any legal duty to summon aid for Devin first potentially arise?

Explanation. The majority held that a person who justifiably uses force has no duty to assist the aggressor in any manner that may create a risk of bodily injury or death, including remaining in or returning to the zone of risk. The defender's immediate duty is self-preservation by seeking and securing safety. A duty to summon aid may revive only after safety is fully secured, and only if the person knows facts indicating a duty and is physically capable of acting.
