Utah Court of Appeals

Can a defendant claim ineffective assistance for counsel's failure to retain a false confession expert? State v. Streeper Explained

2022 UT App 147
No. 20180337-CA
December 22, 2022
Affirmed

Summary

Streeper was convicted of multiple counts of child sexual abuse after confessing to family members and police that he drugged and sexually assaulted his daughters and other young relatives. At trial, he admitted to some acts but claimed other portions of his confessions were false. On appeal, he argued ineffective assistance for counsel’s failure to retain a false confession expert.

Analysis

In State v. Streeper, the Utah Court of Appeals addressed whether defense counsel’s failure to retain a false confession expert constituted ineffective assistance of counsel in a child sexual abuse case. The court’s analysis provides important guidance on the prejudice prong of ineffective assistance claims involving expert witnesses.

Background and Facts

Streeper confessed to family members and police that he had drugged and sexually abused his three young daughters, half-sister, and niece. The confessions included admissions of rape, sodomy, and digital penetration. At trial, Streeper admitted to some acts but claimed portions of his confessions relating to more serious offenses were false, asserting he had been “ganged up on” and pressured into making false statements. The jury convicted on all counts.

Key Legal Issues

On appeal, Streeper claimed ineffective assistance of counsel for trial counsel’s failure to retain a false confession expert. The court conducted a rule 23B remand to develop the record, hearing testimony from a false confession expert who explained police interrogation techniques and factors that can lead to false confessions.

Court’s Analysis and Holding

The Court of Appeals focused on the prejudice prong of the Strickland analysis. The court identified six key factors demonstrating no prejudice: (1) Streeper’s own testimony already established his claim of false confessions; (2) the expert had no basis to analyze confessions to family members; (3) the consistent, corroborative nature of multiple confessions; (4) extensive independent evidence corroborating the confessions; (5) Streeper’s selective parsing of true versus false confessions strained credibility; and (6) the expert’s limited conclusions would not have meaningfully aided the defense.

Practice Implications

This decision demonstrates that expert testimony claims in ineffective assistance cases must show more than theoretical relevance—practitioners must establish that the expert’s testimony would have created a reasonable probability of a different outcome. Courts will examine whether independent corroborating evidence undermines the potential impact of the proffered expert testimony, particularly in cases involving detailed confessions supported by victim testimony and physical evidence.
