Background
Steven Knox was convicted of second-degree assault and unlawful use of a weapon arising from a stabbing. The alleged victim did not testify. During closing argument, defense counsel emphasized gaps in the state’s proof, including the absence of the victim’s testimony and a complete account of the incident.
In rebuttal, the prosecutor asked the jury to speculate whether the victim might not have testified because she feared for her safety. Defense counsel immediately objected, and the trial court directed the jury to disregard the argument. The court later denied Knox’s motion for a mistrial.
The Court’s Holding
The Oregon Court of Appeals held that the prosecutor’s argument was plainly improper because it relied on facts not in evidence, invited speculation about why the victim did not testify, and made an emotional appeal based on the victim’s supposed fear. The argument was significantly prejudicial because it supplied an unsupported answer to a central question and undercut the defense’s strategy of highlighting the state’s failure to present expected evidence.
The trial court’s general instruction to disregard the comment was insufficient to cure that prejudice. The court explained that an adequate instruction needed to tell jurors why the argument was improper—namely, that they could rely only on evidence introduced at trial and could not speculate beyond the record. The denial of a mistrial therefore deprived Knox of a fair trial, requiring reversal and remand.
The court rejected or found no reversible error in Knox’s other claims likely to recur. Evidence of the victim’s wound, pain, and difficulty breathing made any unpreserved insufficiency claim concerning physical injury not plainly erroneous. The court also held that Knox was not entitled to a less-satisfactory-evidence instruction because both parties had equal power to subpoena the victim, and it rejected his pro se claims concerning a prior conviction, confrontation rights, trial delays, and pretrial detention.
Key Takeaways
- A prosecutor may not invite jurors to explain a missing witness’s absence by relying on speculation or facts outside the evidentiary record.
- A bare instruction to disregard an improper argument may be inadequate when the argument creates an adverse inference, appeals to emotion, and undermines a central defense strategy.
- A less-satisfactory-evidence instruction is not required when both sides have equal access to the allegedly stronger evidence, including through subpoena power.
Why It Matters
The decision illustrates that a prompt objection and a generic curative instruction do not invariably eliminate prejudice from prosecutorial misconduct. When an improper argument supplies an unsupported explanation for a critical evidentiary gap, the trial court may need to identify the specific problem and remind jurors that their decision must rest only on trial evidence.
The opinion is a nonprecedential memorandum opinion under ORAP 10.30 and may be cited only as that rule permits.
