Background
Pennington was in a relationship with the victim’s mother when the victim was thirteen to fourteen years old. Beginning with wrestling that progressed to removing her clothing, Pennington engaged in escalating sexual abuse including groping and, on multiple occasions more than once per month, vaginal penetration—sometimes while pinning the victim’s wrists so she could not resist. When the victim disclosed the abuse to her mother, the mother disbelieved her and told her the conduct was “normal” and “fine.” The victim eventually stopped staying with her mother and Pennington. After turning eighteen, the victim reported the abuse to police.
Police and the Division of Criminal Investigation conducted separate investigations. The victim’s disclosures were consistent across multiple interviews. Pennington denied wrongdoing in a ninety-minute police interview and claimed that digitally altered photos of the victim and her siblings pasted onto swimsuit models were a “body image exercise”—an explanation the investigating agent found implausible. The victim’s sister testified she witnessed wrestling between Pennington and the victim but did not witness sexual abuse; she also confirmed Pennington and the victim were sometimes alone together. Police records described the victim’s mother’s history with law enforcement and noted she had previously coached another child into making false allegations against their biological father.
A child protection expert testified about sexual abuse dynamics, including grooming through progressive touch, delayed disclosure in cases where victims fear disbelief, and why abused children may remain in contact with abusers. A jury convicted Pennington of two counts of sexual abuse in the third degree (class C felonies) and one count of indecent contact with a child (aggravated misdemeanor).
The Court’s Holding
The court addressed Pennington’s challenge to the jury instruction on witness corroboration. The district court had instructed: “There is no requirement that the testimony of a complaining witness be corroborated. Likewise, there is no requirement that any other witness, including the defendant’s testimony be corroborated.” Pennington argued the instruction should have simply stated no witness testimony requires corroboration. The Iowa Supreme Court had previously found similar instructions erroneous in State v. Kraai, State v. Mathis, and State v. Ross because they singled out the victim’s testimony as not requiring corroboration while implying other witnesses’ testimony might require it.
The Court of Appeals held the instruction given here was not erroneous because it avoided the asymmetry condemned in prior cases—it universally applied the noncorroboration principle to all witnesses, including both the victim and the defendant. The court noted the instruction’s drafting was imperfect and cautioned that while technically compliant with case law, it was not a “best practice.” The court emphasized that trial courts should follow the Iowa Supreme Court’s preferred formulation: “No witness’s testimony needs to be corroborated to be believed.” Accordingly, the conviction was affirmed on the instructional issue.
Regarding sentencing, the State conceded on appeal that the district court imposed an excessive minimum fine. The court had imposed a $1,370 fine per sex-abuse count, apparently believing that was the applicable statutory minimum. However, the correct minimum fine effective on the offense dates was $1,000. The court vacated only the fine portion of the sex-abuse sentences and remanded for limited resentencing to address those fines only.
Key Takeaways
- Sexual abuse convictions may rest entirely on uncorroborated victim testimony; no corroboration is legally required.
- Jury instructions on witness corroboration must apply universally to all witnesses and avoid singling out victims as not requiring corroboration.
- Trial courts should use Iowa Supreme Court-approved language for noncorroboration instructions going forward, preferring the formulation: “No witness’s testimony needs to be corroborated to be believed.”
- Sentencing courts must apply the statutory minimum fine in effect on the offense date, not a higher minimum that was adopted later.
Why It Matters
This decision clarifies Iowa law on a recurring instructional issue in sexual abuse prosecutions. Although the court found the instruction technically proper, it signaled to trial courts that compliance with case law is not the same as approval, and reinforced the Supreme Court’s preferred approach. For prosecutors, the decision confirms that victim testimony alone—without corroboration—is sufficient to sustain conviction if it meets the reasonable doubt standard. For defense counsel, it emphasizes the importance of preserving specific objections to jury instructions and ensuring trial courts apply correct statutory sentencing minimums.
The decision also illustrates how appellate courts distinguish between errors that are harmless versus those that warrant reversal, and the difference between an instruction that technically avoids reversal and one that represents best practice going forward. The remand on sentencing reflects courts’ increasing scrutiny of compliance with statutory sentencing requirements.
