THE UTAH COURT OF APPEALS

STATE OF UTAH, Appellee, v. MILLER E. COSTELLO, Appellant.

Opinion No. 20230157-CA Filed April 3, 2025

Second District Court, Ogden Department The Honorable Michael D. DiReda No. 171901546

Freyja Johnson, Emily Adams, and Hannah Leavitt-Howell, Attorneys for Appellant Derek E. Brown, Michael D. Palumbo, and William M. Hains, Attorneys for Appellee, assisted by law student Rebecca Barker 1

JUDGE RYAN M. HARRIS authored this Opinion, in which JUDGES MICHELE M. CHRISTIANSEN FORSTER and DAVID N. MORTENSEN concurred.

HARRIS, Judge:

¶1 Miller E. Costello pled guilty to aggravated murder for his role in the abuse-related death of his three-year-old daughter, Ava. 2 Later, after a multi-day sentencing hearing, the district court sentenced Costello to life in prison without the possibility of parole. Costello now appeals his sentence, asserting that the court

2. A pseudonym. State v. Costello

improperly double-counted aggravating factors, failed to adequately consider certain items of mitigating evidence, and generally imposed an inappropriate sentence. We discern no abuse of discretion in the court’s sentencing decision, and we therefore affirm.

BACKGROUND

¶2 In July 2017, law enforcement officers were notified of a child who was unconscious and not breathing. Upon responding, officers observed a small child, later identified as Ava, lying on the floor in a virtually empty living room. They quickly determined that Ava was “deceased,” and they realized “immediately that this was a criminal scene” and that Ava “did not die of any natural causes.” Ava appeared to be “extremely malnourished.” Her face was “extremely thin” and “sunken” and had a “bluish-gray color to it.” Officers observed “bruises and marks all over” Ava’s face, which was “very cold to the touch.” Later, officers discovered that Ava had various “bruises and lacerations” all over her body. She had “a large burn on her chest,” as well as “smaller circular burns on her back, legs, and feet” that were “consistent with cigarette burns.”

¶3 During their ensuing investigation, officers interviewed Ava’s parents—Costello and his wife (Mother)—and Mother “admitted to covering [Ava] with make up to conceal some” of her injuries. For his part, Costello acknowledged an awareness that Ava needed urgent medical attention, but he asserted that Ava “was in the sole care of” Mother. Officers searched the parents’ cell phones, and they discovered “several pictures and videos which showed Ava’s deteriorating health conditions” over a time span of about eighteen months. In the videos, Costello and Mother could be seen taunting Ava by showing her food and then preventing her from eating it. One video shows Costello “using the feet of an infant child to kick [Ava] in the face.” In the videos, Ava is in “an obvious state of emotional duress and distress.”

¶4 After investigation, the State charged Costello with aggravated murder, citing three aggravating factors: (1) the murder was committed “incident to” the commission of child abuse; (2) the murder “was committed in an especially heinous, atrocious, cruel, or exceptionally depraved manner”; and (3) “at the time of death the victim was younger than 14 years of age.”

¶5 Thereafter, a multi-day preliminary hearing was held, at which several officers and experts testified about the severity of the abuse inflicted on Ava. One detective (Detective), specifically trained in investigating child abuse cases, remarked that Ava “looked like a Holocaust victim.” A police investigator testified that Ava’s “malnutrition reminded [him] of pictures you see of kids in concentration camps.” And a medical examiner testified that Ava was “severely malnourished” and that she weighed less than fourteen pounds, placing her in “less than a 1st percentile for body weight.” The medical examiner reiterated several times that Ava’s injuries were caused by “non-accidental trauma” and that Ava suffered injuries on “pretty much every compartment of her external body.” At the conclusion of the preliminary hearing, the district court bound Costello over for trial, and it issued a written decision setting forth its reasoning.

¶6 In the wake of the preliminary hearing, the State filed a notice indicating its intent to seek the death penalty against Costello, and it filed an amended information to that effect. Some time later, Costello entered into a plea agreement with the State, whereunder Costello agreed to plead guilty to aggravated murder and the State agreed to decline to seek the death penalty.

¶7 A few weeks later, the district court held a sentencing hearing, which took place over four days. At that hearing, the State played a recording of a 911 call made by a concerned citizen about five weeks prior to Ava’s death. The concerned citizen had been shopping at a clothing store and had been shocked by Ava’s malnourished appearance. On the call, the citizen reported that

“[t]he dad”—referring to Costello—“said he would wait” at the store for emergency personnel to arrive. But Costello and Mother took Ava and left the store without waiting for responders.

¶8 During the hearing, the State also discussed how the abuse affected not only Ava but also her older brother (Brother), who not only witnessed the abuse visited upon Ava but was, at times, also forced to participate in it. The State presented a report from Brother’s counselor in which the counselor described “some experiences [Brother] went through and continues to struggle with nearly six years later.” The report emphasizes that “[Brother] is now almost 10 and continues to have a very clear memory of what torture he witnessed occurring to his sister and what he participated in with the direction of his parents.” The report states that, at some point, Brother even “became suicidal due to the grief and guilt he felt.”

¶9 Detective testified at the hearing and described the photos and videos found on Costello’s phone that “basically documented” the abuse over an eighteen-month period, including videos of Costello and Mother taunting Ava with food and then refusing to give her any. Detective also stated that, for her, this case had been “a career ender,” explaining that she had decided to leave police work “because of what [Ava] endured and what [Detective] had to watch her go through.” A pediatric physician testified that Ava was old enough to understand “what was happening” when her parents were withholding her food and abusing her. When discussing Ava’s weight, the physician testified that Ava “wasn’t even on a growth curve for a three-year- old, but she was the same weight as a six-month-old at the time of her death” and that “[h]er malnutrition was beyond a stage that we see in the United States.”

¶10 A mitigation specialist (Specialist) testified on behalf of Costello, and she informed the court that Costello “had a very low IQ” and that he had not attended very much school. She also
