Background

Montgomery McKernan went to a Salvation Army food pantry without a scheduled pickup appointment. After a receptionist told him he would need to wait, he repeatedly used profane and derogatory language toward her. A manager testified that McKernan also threatened to choke the receptionist. Employees repeatedly directed him to leave.

A patron intervened after hearing McKernan’s language. The State’s witnesses testified that McKernan shoved her to the floor, causing bruising; McKernan testified that she pushed him first and that he acted in self-defense. A jury convicted him of assault causing bodily injury.

The Court’s Holding

The Iowa Court of Appeals affirmed. The district court did not abuse its discretion by denying McKernan’s ninth continuance request, made two days before trial after numerous prior delays and after he missed the court’s deadline to waive speedy trial. McKernan did not show good cause or resulting injustice from proceeding to trial.

The court also upheld the self-defense instructions. Substantial evidence supported instructing the jury that McKernan may have been engaged in disorderly conduct through threatening and abusive epithets likely to provoke a violent reaction, which could trigger a duty to retreat. In any event, the general verdict was supported by other theories rejecting justification, including evidence that the patron did not use force first. The court further found no abuse of discretion in refusing a spoliation instruction concerning alleged photographs that were not shown to exist, or in denying an on-site jury view where photographs and diagrams could present the relevant layout.

Key Takeaways

  • A last-minute continuance may properly be denied after repeated prior delays and a missed court-ordered deadline.
  • Targeted, repeated abusive epithets and a reported threat may support a disorderly-conduct instruction in a self-defense case.
  • A spoliation instruction requires substantial evidence that the allegedly destroyed evidence actually existed.

Why It Matters

The decision illustrates that Iowa’s stand-your-ground protection does not eliminate a duty to retreat for a defendant engaged in unlawful activity. It also confirms that, when a jury returns a general guilty verdict on multiple theories, the conviction stands if sufficient evidence supports at least one instructed theory.
