In State v. Casey, 2003 UT 55, 82 P.3d 1106, the Court held that to convict a defendant of attempted murder under Utah's criminal attempt statute, "the prosecution must show that the defendant acted intentionally." The Court explicitly distinguished this from a knowing mens rea. The Court held in Casey that neither a knowing nor a depraved indifference mens rea is sufficient to satisfy the intent requirement of Utah's criminal attempt statute.
