¶ 1 A jury fоund Jeremy Millis guilty of one count of intentional or knowing child abuse under circumstances likely to result in death or serious physical injury and one count of first-degree murder, both committed against a victim under age fifteen. Millis was sentenced to life imprisonment without the possibility of release for thirty-five years for murder, to be followed by a consecutive ten-year prison term for child abuse, On appeal, he contends the trial court erroneously precluded expert testimony about his аutism, he was prejudiced by a duplicitous charge, and the court erred by allowing the victim’s mother to be accompanied at trial by a facility dog.
Factual and Procedural Background
¶ 2 “We view the facts and all reasonable inferences therefrom in the light most favorable to upholding the jury’s verdict[s].” State v. Causbie,
¶3 On the morning of January 24, 2013, S.F. changed the diaper of her eight-month-old son, C.K. He had no bruises on him. She later took some pictures of C.K. “having a lot of fun ,.. and being very smiley” in his bouncer, Millis arrived to babysit the boys and she left for work at around 2:00 p.m, Millis was the only person watching the boys while S.F, was at work.
¶4 S.F, arrived home around 11:00 p.m. She looked in on the boys and they appeared to be аsleep. Millis told S.F. that C.K. had been coughing and choking earlier that night, but S.F. was not worried because she knew C.K. had a condition called tracheomalacia, a “floppiness” in the cartilage of the trachea that sometimes caused him to make choking sounds, cough, or wheeze. Millis left and S.F. went to bed.
¶ 5 C.K, woke up at about 2:30 or 3:00 a,m. and S.F. tried to feed him a bottle. He did not eat much, but seemed to go back to sleep after about fifteen or twenty minutes. Then at about 6:30 a.m., C.K. started crying in a way that “didn’t sound right. It wasn’t his normal cry.” S.F. picked him up but he would not open his eyes or respond to his name, and she had to hold his head up.
¶ 6 S.F, rushed C.K. to the hospital, which was across the street from her apartment, When they arrived at the emergency room, the staff took him right away, but he began
¶ 7 C.K, had bilateral subdural hematomas, which caused bleeding on both sides of his brain, bruising, and swelling. Analysis of a CT scan indicated the head trauma had occurred within approximately the last twenty-four hours, and could not have been the result of C.K. merely falling back onto carpet from a seated position. His fontanel was also bulging, and in each eye he had “too many [retinal hemorrhages] to count” across all layers of the retina. C.K. also had bruises on his head, ears, neck, chin, upper arms, shoulders, and “wrap[ping] around” his chest and rib cage. Numerous medical professionals testified that C.K.’s injuries were not consistent with an accidental fall, but were consistent with blunt force head trauma, intentional choking, and violent shaking.
¶ 8 C.K. died on January 30, five days after he was admitted to the hospital. A forensic pathologist opined that the date of the injuries was five to six days prior to death. The pathologist ruled C,K.’s death a homicide and determined the co-equal and interrelated causes of death to bе (1) blunt force trauma to the head, and (2) hypoxic ischemic injury, which is a lack of oxygen and blood to the brain.
¶ 9 S.F. was interviewed by investigating detectives the day C.K. was admitted to the hospital. She showed them her text message exchange with Millis. They located Millis, advised him of his Miranda
¶ 10 At trial, Millis argued the blunt force trauma alone could have causеd the brain swelling, which in turn could have choked off oxygenated blood to the brain, causing the hypoxic ischemic injury notwithstanding any strangulation. However, the forensic pathologist testified that the blunt force trauma alone could not account for certain injuries noted on an MRI. In closing, Millis argued that his choking the baby was not what killed him, that S.F, had inflicted the injuries that caused C.K,’s death after he had left that night, and that “shaking plus impact explains the [whole] universe of injuries that we have.” In the alternative, he argued he had choked C.K. recklessly or negligently, not intentionally.
¶ 11 The jury convicted Millis of all charges and he was sentenced as described above. We have jurisdiction pursuant to A.R.S. §§ 18-4031 and 13-4033(A)(1).
¶12 Millis argues the trial court erred by precluding a defense expert from testifying Millis suffers from autism spectrum disorder (ASD) when it concluded that the proffered testimony was diminished capacity evidence as opposed to character trait evidence. We review a ruling to admit or preclude expert testimony for an abuse of discretion. State v. Wright,
¶ 13 Before trial, defense counsel filed a motion to assess Millis’s competency pursuant to Rule 11.2(a), Ariz. R. Crim. P. Counsel attached to the motion the opinion of Dr. Pablo Stewart, who concluded in relevant part that Millis suffers from ASD without accompanying intellectual or language impairments. Relying on the testimony of two other experts who rejected that diagnosis, the trial court found Millis competent to stand trial.
¶ 14 Millis asked to continue the trial in order to accommodate Dr. Stewart’s schedule so that he could testify about the ASD diagnosis. The state moved to preclude any ASD testimony, which it characterized as evidence of diminished capacity. Defense counsel argued the ASD diagnosis would not be offered to show diminished capacity, but to show Millis had а character trait of “difficulty in understanding how to interact appropriately with others,” which could have made it “more or less likely that he formed the intent required in this particular ease.” After a heai’-ing at which Millis made an offer of proof, the trial court granted the state’s motion to preclude Stewart’s testimony, finding it was offered to support a diminished capacity defense and was not character evidence. The court also denied Millis’s motion to continue the triаl.
¶ 15 Arizona does not recognize a “diminished capacity” defense, in which expert psychiatric evidence about a defendant’s mental incapacity is offered to negate mens rea. State v. Mott,
¶ 16 In Mott, our supreme court affirmed preclusion of evidence that “battered-woman syndrome” and low intelligence diminished the defendant’s capacity to decide to seek medical care for her child.
¶ 18 Millis argues in the alternative that Dr. Stewart should have been allowed to present limited “observation evidence” about Millis’s character traits without mentioning the ASD diagnosis. See Clark,
¶ 19 Millis’s reliance on State v. Christensen,
Duplicitous Charges
¶20 Millis next contends duplicitous charges deprived him of his right to a unanimous jury verdict.
¶ 21 The right to a unanimous jury verdict is established in the Arizona Constitution. Ariz. Const, art. II, § 23. In the context of statutes describing offenses that may be committed in multiple ways—sometimes referred to as “alternative-means” or “single unified offense” statutes—the jury must be unanimous as to whether the charged criminal act has been committed. State v. West,
¶ 22 First-degree murder is a single unified offense. See, e.g., State v. Tucker,
¶ 23 Similarly, child abuse under circumstances likely to produce death or serious physical injury pursuant to AR.S. § 13-3623(A) is also a single unified offense. West,
¶ 24 Here, the trial court instructed the jury that in order to convict Millis of first-degree felony murder, the state was required to prove (1) the victim’s death occurred in the course of and in furtherance of the predicate felony (intentional or knowing child abuse under circumstances likely to produce death or serious physical injury), (2) “the death was proximatеly caused by the acts of the defendant,”
¶ 25 Millis argues even if child abuse under § 13-3623(A)(1) is a single unified offense, he suffered a duplicitous charge pursuant State v. Klokic,
¶26 Finally, even if a duplicity error had occurred, Millis has not met his burden of showing prejudice. Henderson,
Victim’s Use of Facility Dog at Trial
¶ 27 Millis argues the trial court denied him due process and a fair trial by allowing a facility dog and its handler to sit beside S.F. during the trial. In keeping with the trial court’s “broad discretion” in managing trial conduct, State v. Cornell,
¶ 28 Following S.F.’s appearance at various pretrial hearings accompanied by a facility dog named “Blake,” Millis brought a motion in limine to preclude Blake’s presence at trial. He argued Arizona crime-victim law gives a victim a right to be accompanied by a support person, not a support animal, and that the dog would unfairly prejudice him by inviting the jury to base its decision on emotion or sympathy. The state argued Blake would not prejudice Millis, and would help S.F. testify in the midst of difficult circumstances. After a hearing, the trial court found that the dog’s presence would not unfairly prejudice Millis. Although the judge expressed a personal preference that Blake not be present, she saw no “legal basis” to exclude the dog and denied the motion. Millis moved for reconsideration, and the court denied that motion as well.
¶ 29 The state argues we should review the due process aspect of Millis’s claim for fundamеntal error, citing Henderson,
¶ 30 As Millis observed in his motion in limine, Rule 39(b), Ariz. R. Crim. P., gives a crime victim
¶31 Several other states, however, have considered the question and at least five have approved the use of dogs to accompany witnesses under appropriate circumstances. See People v. Chenault,
¶ 32 Millis first asserts that a dog accompanying a victim is “presumptively prejudicial” so as to jeopardize a fair trial in every case, and contends it “presentís] a nonevi-dentiary message” to the jury that the witness is an innocent victim. Other courts have rejected these arguments, as do we. See Chenault,
¶33 Millis further argues the trial court failed to inquire into and weigh the appropriate factors to determine whether a facility dog was appropriate in this particular case and for this particular’ victim, in an abdication of its role in exercising discretion. See State v. Garza,
Disposition
¶ 34 We affirm Millis’s convictions and sentences for the reasons stated above.
Notes
. Although cases refer to victim/witness support dogs using many different terms, see, e,g., People v. Spence,
. See Miranda v. Arizona,
. At another point, Millis told the detective that he had only "squeezed” C.K.’s neck because C.IC was having trоuble breathing and Millis was trying "to see if there was something there, if he could move [the neck] around.”
. This limitation comports with due process. Clark v. Arizona,
. Millis does not argue he faced a duplicitous indictment. See generally State v. Klokic,
. The instruction went on to define proximate causation.
. The knowing or intentional mens rea for child abuse under § 13—3623(A)(1) applies only to the defendant’s actions, not to the "under circumstances likely to produce death or serious physical injury” prong. See Payne,
. In his motion for reconsideration, Millis argued in the alternative that he too should be allowed to have a dog with him during trial as a matter of еqual protection. The state did not oppose Mil-lis’s request, but when the trial court asked Millis if having a dog with him at trial would actually comfort him, he said he did not think so and he did not need one. The court then denied Millis’s request. He does not challenge this ruling on appeal, nor does he raise an equal protection argument.
. It is undisputed that S.F., as C.K.'s mother, is a "victim” under Arizona law. Ariz. Const, art. II, § 2.1(C); A.R.S. § 13-4401(19); Ariz. R. Crim. P. 39(a)(1).
. Dye involved a developmentally disabled adult victim with an IQ of 65 and a mental age ranging from six to twelve years old whо was "very scared" to testify about burglaries of his home.
.The statute also requires a jury instruction in cases involving a facility dog, in order "[t]o ensure that the presence of [the] facility dog ... does not influence the jury or is not a reflection on the truthfulness of any testimony” the witness offers. § 13-4442(C).
. The factors the trial court considered in exercising its discretion in this case are not the only factors a court may properly consider in determining whether to allow witness accommodations, nor are they necessary considerations in every case.
