Background
Joseph C. Castle, born June 1984, was friends with Michaela R., the mother of L.R., a child born in March 2019. In October 2023, Castle invited Michaela and L.R. to swim at a hotel where he was staying. After Michaela left, L.R. remained alone with Castle. When L.R. had a diaper accident, Castle changed her and touched the outside of her vagina multiple times with his finger. Castle expressed upset about the accident.
In March 2024, after L.R. was placed in her aunt’s care for unrelated reasons, L.R. disclosed to her aunt Amber S. that Castle had hurt her in a hotel room, pointing to her vagina. L.R. made a similar statement to a preschool classmate, prompting a report to the Department of Health and Human Services. A forensic interview at Project Harmony and medical examination confirmed L.R.’s account that Castle had touched only the outside of her vagina.
Castle was charged with attempted first degree sexual assault of a child under Neb. Rev. Stat. §§ 28-319.01 and 28-201. Following a jury trial in July 2025, he was convicted and sentenced in September 2025 to 15 to 20 years’ incarceration.
The Court’s Holding
The Nebraska Court of Appeals affirmed Castle’s conviction on all grounds. The court rejected his challenge to the jury instruction defining “sexual penetration,” holding that the trial court properly omitted inapplicable statutory language and that sexual penetration does not require sexual arousal or gratification. The instruction correctly stated that sexual penetration means “any intrusion, however slight, into the genital or anal openings of a victim by any part of the defendant’s body which can be reasonably construed as being for non-medical, non-health, or non-law enforcement purposes.” The court clarified that while “sexual contact” requires conduct “reasonably construed as being for the purpose of sexual arousal or gratification,” the definition of sexual penetration contains no such limitation.
The court upheld expert testimony from L.R.’s therapist describing general trauma symptoms in children, distinguishing it from impermissible “validation testimony” that would opine on a victim’s credibility. The court also held that a limiting instruction regarding hearsay was not required because Castle’s counsel never requested one, and trial courts have no duty to provide limiting instructions sua sponte. Regarding ineffective assistance claims, the court found counsel was not deficient for failing to object to the nurse practitioner’s treatment recommendation, characterizing it as medical decision-making rather than credibility validation.
Key Takeaways
- Under Nebraska law, sexual penetration of a child does not require proof of sexual arousal, gratification, or sexual intent—touching a child’s genitals satisfies the statute without evidence of sexual motivation.
- Expert testimony about general trauma symptoms in sexually abused children is admissible to help jurors understand abuse dynamics; such testimony does not impermissibly validate a victim’s credibility if it does not opine on the victim’s truthfulness or the truth of specific allegations.
- Trial courts are not required sua sponte to provide limiting instructions on evidence admissibility; absent a request from counsel, failure to give a limiting instruction does not constitute error.
- Medical professionals’ treatment recommendations based on a patient’s reported history do not constitute expert opinions on the patient’s credibility merely because the professional proceeded with treatment rather than questioning the patient’s veracity.
Why It Matters
This decision clarifies an important distinction in Nebraska child sexual assault law: prosecutors need not prove sexual intent or arousal to establish the crime. By holding that sexual penetration is a distinct offense from sexual contact, the court ensures that even touches without sexual motivation can constitute criminal penetration. This interpretation significantly expands the reach of child protection statutes and may make prosecutions more straightforward when physical touching of a child’s genitals occurs, regardless of the defendant’s subjective motivation.
The decision also reinforces boundaries around expert testimony in sexual abuse cases. While permitting helpful context about trauma symptoms, the court maintains the prohibition on experts vouching for victim credibility—a critical safeguard against trial evidence that usurps the jury’s fact-finding role. For practitioners, the ruling underscores the importance of requesting limiting instructions at trial; failure to do so forecloses appellate arguments on that ground.
