Utah Court of Appeals
Can evidence of acquittal on underlying charges be excluded in witness tampering cases? State v. Plexico Explained
Summary
Plexico was convicted of witness tampering after allegedly asking a friend to lie to police about an assault. The charges were severed from the underlying assault charges, of which Plexico was later acquitted. The trial court excluded evidence of the acquittal and gave jury instructions on the required mental state.
Practice Areas & Topics
Analysis
The Utah Court of Appeals recently addressed several key issues in witness tampering prosecutions, including the admissibility of evidence regarding a defendant’s acquittal on underlying charges and the sufficiency of evidence required for conviction.
Background and Facts
Shoni Plexico was charged with witness tampering after allegedly asking a friend to lie to police about an assault incident. The friend had initially told police that Plexico hit her boyfriend, leading to assault charges against Plexico. Two hours later, the friend told police that Plexico had asked her to change her statement and deny that any assault occurred. The assault charges and witness tampering charge were severed for trial. Plexico was subsequently acquitted of the assault charges but convicted of witness tampering.
Key Legal Issues
The court addressed three primary issues: (1) whether sufficient evidence supported the witness tampering conviction under Utah Code section 76-8-508; (2) whether the trial court abused its discretion by excluding evidence of Plexico’s acquittal on the underlying assault charges; and (3) whether the jury instructions adequately conveyed the required mental state for the offense.
Court’s Analysis and Holding
The Court of Appeals affirmed the conviction on all grounds. First, the court found sufficient evidence supported the conviction, noting that the witness tampering statute explicitly prohibits attempting to induce someone to “testify or inform falsely” regarding an official proceeding. The court rejected Plexico’s argument that merely asking a friend to lie was insufficient, emphasizing that the statute criminalizes such conduct when connected to official proceedings.
Second, the court held that excluding evidence of Plexico’s acquittal was proper under Utah Rules of Evidence 402 and 403. The trial court correctly determined that such evidence was irrelevant to whether Plexico believed an official proceeding was pending or attempted to induce false testimony. The court noted that allowing such evidence would confuse the jury by inviting speculation about why the previous jury reached its verdict.
Third, the court found no error in the jury instructions, distinguishing the case from State v. Geukgeuzian. Unlike in Geukgeuzian, the trial court here adequately instructed the jury on the required mens rea, explicitly stating that the prosecution must prove the defendant acted “intentionally, knowingly or recklessly with respect to each element of the crime.”
Practice Implications
This decision clarifies several important points for practitioners handling witness tampering cases. Courts will likely exclude evidence of acquittals on underlying charges unless directly relevant to an element of the tampering charge. Additionally, when challenging sufficiency of evidence, defendants must marshal all evidence supporting the verdict—a failure that “almost certainly” dooms the appeal. Finally, jury instructions on mental state requirements must be evaluated as a whole, not in isolation.

Citation

Court
Utah Court of Appeals
Case Number
No. 20140590-CA
Date Decided
June 3, 2016
Outcome
Affirmed
Holding
The trial court properly convicted defendant of witness tampering where evidence showed she attempted to induce a witness to testify falsely regarding an official proceeding, and the court did not abuse its discretion in excluding evidence of defendant’s acquittal on underlying charges or in giving jury instructions that adequately conveyed the required mens rea.
Standard of Review
Sufficiency of evidence is reviewed under a highly deferential standard; trial court’s evidentiary rulings under rule 404(b) are reviewed for abuse of discretion; jury instruction challenges not preserved are reviewed for plain error
Practice Tip
When challenging sufficiency of evidence on appeal, defendants must marshal all evidence supporting the verdict before demonstrating its inadequacy, or the challenge will almost certainly fail.
