Utah Supreme Court

State v. Castillo

July 30, 20262026 UT 26

Summary

The court affirmed Castillo’s convictions for four counts of aggravated sexual abuse of a child and one count of rape of a child. It held that Castillo waived most of his rule 702 challenges, and that his remaining ineffective-assistance claims failed because counsel’s trial choices were objectively reasonable. The court also rejected Castillo’s plain-error claim concerning the word “victim” and held that his inherent-improbability challenge was unpreserved and that counsel was not ineffective for failing to raise it.
