Can Utah courts admit evidence of other acts of child molestation? State v. Alvarado-Rodriguez Explained

In State v. Alvarado-Rodriguez, the Utah Court of Appeals clarified important aspects of admitting evidence of other acts of child molestation under rule 404(c) of the Utah Rules of Evidence. The case provides crucial guidance for practitioners handling child sex abuse cases.

Background and Facts

Aaron Alvarado-Rodriguez was convicted of sexually abusing his eleven-year-old stepdaughter Rachel in 2001. The State sought to introduce evidence that Alvarado-Rodriguez had also sexually abused another child, Alison, when she was eight years old in the late 1990s. While the specific acts differed—Rachel’s case involved forced touching of defendant’s penis, while Alison’s involved digital penetration—both occurred in similar circumstances with the defendant entering the children’s bedrooms while they slept.

Key Legal Issues

The central issue was whether the trial court properly admitted evidence of Alvarado-Rodriguez’s abuse of Alison under rule 404(c). Defendant argued the evidence should be excluded under rule 403 because the acts were dissimilar and carried high risk of unfair prejudice, describing “more serious conduct of object rape compared to Rachel’s charges of aggravated sexual abuse.”

Court’s Analysis and Holding

The court affirmed admission of the evidence. Under rule 404(c), evidence of other acts of child molestation may be admitted “to prove a propensity to commit the crime charged” without requiring articulation of a non-propensity purpose. The court found Alison’s testimony had significant probative value despite differences in the specific acts, noting similarities in the victims’ ages, timeframe, and circumstances. The court rejected arguments about unfair prejudice, emphasizing that differences in specific acts do not meaningfully reduce probative value when both incidents constitute child molestation.

Practice Implications

The decision confirms that rule 404(c) evidence retains substantial probative value even when the specific sexual acts differ from the charged conduct. Practitioners defending against such evidence should focus on extraneous “technicolor details” beyond the propensity inference rather than mere differences in the acts themselves. The case also clarifies that delayed reporting and lack of prior conviction do not diminish the probative value of other-acts evidence under rule 404(c).
