In State v. DeMille, 756 P.2d 81, 83 (Utah 1988) the Court held that the state of mind necessary for a murder conviction was satisfied by expert testimony regarding a child's injuries in a child abuse case. In that case, the evidence showed only that a three-year-old child was in the care of the defendant when she sustained a skull fracture and attendant brain injury that was caused by a blunt object striking "with a force equivalent to a fall from a two- or three-story building."
