When can juries infer penetration in sexual assault cases? State v. Patterson Explained
Summary

Practice Areas & Topics
Analysis
In State v. Patterson, the Utah Court of Appeals addressed a critical evidentiary question in sexual assault prosecutions: when can a jury reasonably infer penetration occurred without explicit testimony? The case provides important guidance on the boundary between permissible inference and impermissible speculation in sufficiency of evidence challenges.
Background and Facts
Patterson, age 23, was convicted of object rape involving a 17-year-old coworker. The victim testified that Patterson pushed her into her car’s back seat, removed her pants, and touched her vagina. Crucially, she testified that when Patterson was “trying to put his fingers up” her vagina, he “separated the labia” using “two fingers,” causing pain “I had never felt anything like that before.” However, the victim never explicitly testified that penetration occurred.
Key Legal Issues
The central issue was whether the evidence supported the penetration element of object rape under Utah Code § 76-5-402.2(1), which requires “penetration, however slight, of the genital opening” by a foreign object or body part. Patterson argued the victim’s testimony was insufficient because it never explicitly described penetration occurring.
Court’s Analysis and Holding
The court applied the critical distinction between permissible inference and impermissible speculation. While the victim’s testimony could support either penetration or non-penetration, the court found the testimony was not “equally consistent” with both interpretations. The victim’s description of unique pain, combined with her testimony about digital “separation” of labia and Patterson’s own admission that he was attempting penetration, created sufficient evidentiary foundation for the jury to reasonably infer penetration occurred.
Practice Implications
The decision highlights the importance of specific testimony in sexual assault cases. The court cautioned prosecutors to “elicit specific testimony regarding each and every element” rather than relying on inference. Defense counsel should carefully examine victim testimony for gaps in proof of essential elements, particularly the technical requirements of penetration statutes.
