When must Utah defense counsel present impeachment evidence? State v. Salazar Explained

In State v. Salazar, the Utah Court of Appeals addressed a critical question for defense attorneys: when is it constitutionally required to present impeachment evidence against a key witness, even when strategic concerns exist?

Background and Facts

Kevin Salazar was convicted of aggravated sexual assault based primarily on the victim Shannon’s testimony. Shannon experienced significant memory problems at trial, stating “I don’t remember” over 40 times and requiring documents with highlights and sticky notes to refresh her recollection. Critically, Shannon testified under oath at the preliminary hearing and trial that she had no contact with Salazar after the assault, except for a few messages immediately afterward that she reported to police before blocking him.

However, Salazar’s trial counsel possessed Voxer messages showing Shannon had contacted Salazar approximately three months after the incident. Over eight days, Shannon sent twenty voice messages and one text message, inviting Salazar to social events and discussing personal matters including her father’s cancer diagnosis.

Key Legal Issues

The central issue was whether trial counsel’s failure to present the Voxer messages constituted ineffective assistance of counsel under the Strickland standard, requiring proof of both deficient performance and prejudice.

Court’s Analysis and Holding

The Court of Appeals found both prongs of Strickland satisfied. Regarding deficient performance, the court emphasized that in a case hinging on witness credibility, “any reasonable counsel would have presented the Voxer messages to undermine her credibility.” The court rejected the State’s arguments that counsel reasonably avoided the evidence due to authentication concerns or fear of triggering expert testimony on rape myths, noting that the messages went solely to credibility rather than consent.

For prejudice, the court found the messages would have further undermined Shannon’s already problematic credibility. Unlike the prosecution’s characterization, the messages would not have “confirmed” Shannon’s testimony but directly contradicted her sworn statements about post-assault contact.

Practice Implications

This decision reinforces that when a case turns on witness credibility, defense counsel cannot avoid presenting available impeachment evidence due to strategic concerns about prosecution responses. The court made clear that competent representation requires “giving the jury relevant information to help it gauge the credibility of a critical adverse witness.” Utah practitioners should prioritize thorough investigation and presentation of credibility evidence, even when concerned about potential expert testimony or other prosecution strategies.
