State v. Davis
324 P.3d 678
Utah Ct. App.2014Background
- Defendant Dexter Davis, an inmate at Utah State Prison, was charged with third-degree felony assault by a prisoner for an altercation with Sgt. Benjamin Vanzant.
- At trial two corrections officers (including Sgt. Vanzant) testified that Davis was the aggressor and struck Vanzant, producing a visible bruise; the jury saw a photograph of the bruise.
- Davis testified that Vanzant was the aggressor and contended the officers’ accounts were inconsistent and unreliable.
- The jury found Davis guilty; on appeal Davis challenged the sufficiency of the evidence, arguing the officers’ testimony was so inconsistent and unreliable that no reasonable jury could have believed it.
- The appellate court reviewed whether the officer testimony was inherently improbable or otherwise so weak that no reasonable jury could convict, and whether the verdict could stand given the existence of two eyewitnesses.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Sufficiency of evidence to support conviction | Davis: officers’ testimony was so inconsistent/unreliable that no reasonable jury could credit it | State: two eyewitness officers provided evidence and inferences supporting conviction; credibility is for the jury | Affirmed — sufficient evidence existed because two eyewitnesses corroborated the assault allegations |
| Whether testimony was inherently improbable so appellate court must disregard it | Davis: officers’ statements had contradictions, possible collusion, motive to fabricate, subordinate loyalty — testimony inherently improbable | State: inconsistencies were jury issues; testimony was not physically impossible or apparently false | Affirmed — testimony not inherently improbable; appellate court defers to jury credibility determinations |
