Opinion
PEARCE, Judge:
{1 Dale R. Beckering appeals his aggravated abuse of a vulnerable adult conviction, which was enhanced to a second degree felony because the jury found he had acted in concert with others. Beckering argues that his trial counsel rendered ineffective assistance by inviting errors in the jury instructions and by failing to object to several instances of alleged prosecutorial misconduct and improper testimony. He also argues that the district courts failure to prevent the prosecutorial misconduct and improper testimony constituted plain error. We affirm.
BACKGROUND
T2 On March 25, 2011, a 22-year-old female (Victim) was found dead in Beckerings house. Victim had resided in the house as the ward of Cassandra Shepard, Beckerings stepdaughter. Victim suffered from fetal alcohol syndrome and functioned at a child-like level. Shepard had been appointed as Victims guardian. Shepard managed Victims behavior by allowing her to earn privileges that Shepard would revoke for bad behavior.
T 3 In February 2010, Shepard sent Victim from South Dakota to Utah to live with Beck-ering and his wife-Shepards mother Sherrie Beckering (Wife)-in their one-bedroom apartment in West Valley City. During this period, Wife usually cared for Victim, but Beckering would tend to her when Wife was working.
T 4 In July 2010, Victim knocked on one of Beckerings neighbors doors and reported that she was being abused and she had escaped. The neighbor had never seen Vice-tim before and was surprised when Victim said she lived in Beckerings apartment. Victim was wearing ragged clothes and showed the neighbor bruises on her wrists, forearms, and upper chest. The neighbor spent the day with Victim and allowed her to make several phone calls Although it is unclear who summoned them, police eventually arrived at the apartment complex. The neighbor told the officers about the reported abuse and directed them to Victim. The officers spoke with Victim and indicated they were going to take her to a psychiatric facility.
15 A week or two later, Victim returned to the neighbors apartment and reported that Beckering had instructed Victim to apologize. The neighbor saw Victim only onee more, when Victim was taking out the garbage. Victims hair was buzzed on one side. She explained that one of the women in the apartment had shaved her head as punishment. Victim also reported that she was given only one cup of rice and a glass of water per day and that she was forced to take pills to make her sleep.
T 6 In September 2010, Victim moved back to South Dakota to live with Shepard. After about a month, however, Shepard and Victim returned to the West Valley City apartment. Victims daughter and Shepards two daughters also moved into Beckerings apartment at that time. Shepard and the girls slept in the living room of the apartment. Victim slept in the laundry room.
T7 Upon her return to Beckerings apartment, Victim was having health problems, including sores that failed to heal and trouble toileting herself. She also found it increasingly difficult to earn new privileges and began to lose existing ones. After she lost her television privilege, she was required to stay in the laundry room so she could not see the television. Eventually, Victim was forced to stay in the laundry room most of the time. Shepard put an alarm on the laundry room door to prevent Victim from escaping.
T8 In December 2010, a couple who lived in the building across from Beckerings began noticing Victim standing alone on the balcony of Beckerings apartment. Although it was cold, Victim would be on the balcony clad only in a t-shirt and shorts or pants. They sometimes saw Victim eating or drinking out of a coffee can; whatever was in the can made Victim gag. Other times, they saw Victim inside the storage closet on the baleo-ny. They could see Beckerings living room through the balconys sliding door. They sometimes observed Beckering using a computer while Victim was outside.
9 Eventually, a neighbor called the police after observing Victim on the balcony, kind of erying and just looking down at me, wanting help. The neighbor knew that Becker-ing was home when the police responded because she saw him on the balcony while officers were in the apartment. Shepard told the police that Victim was on the balcony per doctors orders to reduce swelling in her feet. Thereafter, the neighbors continued to see Victim on the balcony, but she was dressed more warmly.
T 10 In early January 2011, Beckering and the other residents of the West Valley City apartment moved to a house in Kearns. Everyone slept in bedrooms at the Kearns house except Victim, who had lost the privilege of having a room and was forced to sleep .in a coat closet. The closet door was fitted with an alarm and kept shut by a shelf or other object placed in front of the door. Although Victim knew to stay quiet, the girls could sometimes hear her whining.
{11 Victim usually stayed in the closet. She was not permitted to sit at the dinner table and had lost the privilege of playing with the girls. Shortly before Victims death, one of the girls saw Victim being bound and placed in the closet. The girl also witnessed Shepard put tape across Victims mouth.
1 12 On March 25, 2011, police and medical personnel responded to a 911 call reporting a possible overdose at the Kearns home. When they arrived, they discovered Victim lying dead on the living room floor. Shepard was attempting to revive Victim. Officers observed that Victims hands and forearms were wrapped so tightly with bandages that she would not have been able to use her fingers or thumbs. Both of her eyes were bloodshot. Officers found a red pepper flake under her right eyelid. Victim was wearing a very soaked toddler-sized diaper and had wounds on her ankles that matched eut zip ties found near her body.
1 13 In the closet where Victim had slept, police found zip ties attached to the clothing rod such that a person could be bound with outstretched arms. Cardboard on the floor appeared to be stained with blood, urine, and feces. Scented pine cones and baking soda had been placed in the closet in an apparent attempt to mask the resulting odor. Outside the closet, a metal shelf had been mounted on the wall next to the door. The shelf held a Lysol bottle, deodorizer, duct tape, and a saucepan containing a steak knife, pepper seeds, and nylon zip ties, two of which were cut. On the wall of the closet, there was a fairly large drawing of a suffering Jesus with the thorns on his head.
4 14 A post-mortem examination of Victim revealed redness caused by contact dermatitis, possibly the result of exposure to a chemical spray, on her face and inside her mouth. She had a bruise on her forehead and bruises on her left hip and right leg consistent with having been struck by an object. Ulcers had formed underneath the bandages on her hands, which had not healed because the bandages were wrapped tightly. Toxicology testing revealed a toxic and possibly fatal dose of antihistamine-nine times the therapeutic level-in Victims system. Victim was also severely dehydrated. The medical examiner ruled Victims death a homicide caused by physical abuse and neglect.
{15 Police arrested Beckering, Shepard, and Wife. Beckering submitted to a police interview, wherein he consistently denied any knowledge of Victims abuse. Although he initially denied any role in Victims care, he eventually admitted that he sometimes cared for Victim at the West Valley City apartment. He claimed that he kept his distance from Victim because she had falsely accused him of rape and he was afraid that she would do so again. Beckering told police that he and Wife lived primarily in the basement of the Kearns home, that he worked twelve-hour shifts, and that when he returned home from work he might see Victim for five seconds before going downstairs.
116 Beckering admitted that he knew of the bandages on Victims hands, but he told police that he believed Shepards explanation that the bandages were designed to prevent Victim from harming herself. He also told police that he knew Shepard had placed an alarm on the closet door but that he didnt ask why. Beckering knew that Shepard would not allow Victim to eat dinner with the family, and when Shepard would shuttle food into the living room to feed Victim, he could hear Shepard shouting and telling [Victim] to eat it, swallow it, and dont throw it up.
117 The State charged Beckering with being a party to the intentional or knowing aggravated abuse of a vulnerable adult, a second degree felony subject to an in-concert enhancement to a first degree felony. Beck-erings defense at trial was that he did not know about Victims abuse and that he had no duty to act to protect her. Beckering did not testify at trial. The jury convicted Beck-ering of the lesser-included offense of being a party to reckless aggravated abuse of a vulnerable adult, enhanced to a second-degree felony because it was committed in concert with others. The district court sentenced Beckering to one to fifteen years in prison.
ISSUES AND STANDARDS OF REVIEW
{18 Beckering, represented by new counsel on appeal, contends that his trial counsel rendered ineffective assistance by inviting errors in the jury instructions and by failing to object to several instances of prose-cutorial misconduct and improper testimony. When a claim of ineffective assistance of counsel is raised for the first time on appeal, there is no lower court ruling to review and we must decide whether [the] defendant was deprived of the effective assistance of counsel as a matter of law." Layton City v. Carr, 2014 UT App 227, ¶ 6, 336 P.3d 587 (alteration in original) (quoting State v. Tennyson, 850 P.2d 461, 466 (Utah Ct.App.1998)).
119 Beckering also argues that the district court committed plain error by failing to intervene in the alleged prosecutorial misconduct. The plain error standard of review requires an appellant to show the existence of a harmful error that should have been obvious to the district court. State v. Waterfield, 2014 UT App 67, ¶ 18, 322 P.3d 1194; see also State v. Dunn, 850 P.2d 1201, 1208-09 (Utah 1993) (discussing plain error).
ANALYSIS
I. Jury Instructions
120 Beckering identifies several alleged errors in the jury instructions. He did not object to the jury instructions at trial, and the alleged errors are therefore not subject to ordinary appellate review. See State v. Low, 2008 UT 58, ¶ 17, 192 P.3d 867 ( Where there is no clear or specific objection ... the theory cannot be raised on appeal. (quoting State v. Johnson, 2006 UT App 3, ¶ 13, 129 P.3d 282)). Further, Beck-ering concedes that his counsel invited the alleged errors by approving the jury instructions, thereby precluding review for plain error. See State v. Lee, 2014 UT App 4, ¶ 20, 318 P.3d 1164 ((Invited error precludes appellate review of an issue under the plain error standard.); State v. Alfatlawi, 2006 UT App 511, ¶ 26, 153 P.3d 804 (A defendant invites error where he affirmatively ap-provel[s] of the jury instructions at trial. (alteration in original) (citation and internal quotation marks omitted)). Because the alleged errors in the jury instructions are both unpreserved and invited, Beckering argues that his trial counsel provided ineffective assistance by failing to ensure that the jury instructions were correct.
121 To succeed on an ineffective assistance of counsel claim, Beckering must show both that counsels performance was deficient and that the deficient performance prejudiced the defense Layton City v. Carr, 2014 UT App 227, ¶ 12, 336 P.3d 587 (quoting Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984)). Counsels performance will not be deemed deficient unless a defendant can show that counsels representation fell below an objective standard of reasonableness. Id. (citation and internal quotation marks omitted). There is a strong presumption that counsels conduct falls within the wide range of reasonable professional assistance. Id. (citation and internal quotation marks omitted). To establish the prejudice element of an ineffective assistance of counsel claim, the defendant must show that a reasonable probability exists that, but for counsels error, the result would have been different." Id. (citation and internal quotation marks omitted).
122 Beckering first complains that his counsel should have ensured that the elements instructions made clear that each of several terms in those instructions-inelud-ing party to the offense, vulnerable adult, and caretaker-was a separate factual determination that the State needed to prove and the jury needed to decide. Beckering argues that the elements instructions were too conclusory and they incorrectly presented [the terms] as a given rather than let the jury decide such facts for themselves. For example, the instructions on aggravated abuse of a vulnerable adult asked the jury to find, in part, that Beckering ceause[d] a vulnerable adult to suffer serious physical injury. By Beckerings reading, this language concluded that a vulnerable adult did in fact exist even though such a finding should have been made by the jury. *
128 The general rule for jury instructions is that an accurate instruction upon the basic elements of an offense is essential. State v. Bird, 2015 UT 7, ¶ 14, 345 P.3d 1141 (citation and internal quotation marks omitted). To determine if jury instructions correctly state the law, we look at the jury instructions in their entirety and will affirm when the instructions taken as a whole fairly instruct the jury on the law applicable to the case. State v. Painter, 2014 UT App 272, ¶ 6, 339 P.3d 107 (quoting State v. Maestas, 2012 UT 46, ¶148, 299 P.3d 892); cf. State v. Stringham, 2001 UT App 13, ¶ 17, 17 P.3d 1153 (Failure to give requested jury instructions constitutes reversible error only if their omission tends to mislead the jury to the prejudice of the complaining party or insufficiently or erroneously advises the jury on the law." (citation and internal quotation marks omitted)).
124 We generally presume that a jury will follow the instructions given it. State v. Menzies, 889 P.2d 393, 401 (Utah 1994). When a single element in a eriminal-elements instruction contains multiple factual determinations, the element implicitly requires the jury to resolve each of those factual determinations in favor of the State in order to convict. To use the example Beck-ering advances, the element asking the jury to determine whether he cause[d] a vulnerable adult to suffer serious physical injury required the jury to make; at least three subsidiary factual determinations: (1) that Beckering caused an injury, (2) that the injury was a serious physical injury, and (8) that the injured person was a vulnerable adult. We presume the jury did so, see Menzies, 889 P.2d at 401, and we are not convinced that the organization of the instructions mi-sle[d] the jury or insufficiently or erroneously advise[d] the jury on the law, see Stringham, 2001 UT App 13, ¶17, 17 1153 (citation and internal quotation marks omitted).
125 Beckering also provides this court with no authority for his proposition that a defendant is entitled to, and that his counsel provides ineffective assistance by failing to secure, instructions that present each discrete factual inquiry as a separate element of an offense. Instead, Beckering compares this case to Alleyne v. United States, -- U.S. --, 133 S.Ct. 2151, 186 L.Ed.2d 314 (2013). In Alleyne, a jury convicted the defendant, finding that he had [ulsed or carried a firearm during and in relation to a crime of violence. Id. at 2156 (alteration in original). However, the trial court imposed a statutorily enhanced mandatory minimum sentence based on the courts own determination that the defendant had brandished the firearm. Id. The Supreme Court reversed the conviction, holding that because the finding of brandishing increased the defendants sentence, that determination was an element, which had to be found by the jury beyond a reasonable doubt." Id. at 2163.
126 The Alleyne decision primarily addressed sentencing enhancement factors, abrogating a prior distinction between facts that increase the statutory maximum and facts that increase only the mandatory minimum. Id. at 2155. In doing so, it applied and confirmed the pre-existing general rule that each element of a crime [must] be proved to the jury beyond a reasonable doubt. Id. at 2156. Beckering points to nothing in Alleyne that suggests that elements must be presented to a jury in any particular form. The only aspect of Alleyne that appears to apply to this case is the general requirement that elements of crimes be decided by a jury-a requirement that was satisfied here.
127 We see no deficient performance by counsel in allowing the elements instructions to present multiple factual determinations within individual elements, because the instructions taken as a whole fairly instruct the jury on the law applicable to the case. Painter, 2014 UT App 272, ¶6, 339 P.3d 107 (citation and internal quotation marks omitted). Furthermore, even if counsel had acted unreasonably by failing to seek to limit each element to a single factual question, Beckering has not demonstrated prejudice, because the instructions given still required the jury to resolve each individual factual determination in the States favor to find that the State had proven the elements as a whole. Absent a showing of prejudice, Beckering has not established ineffective assistance of counsel relating to this aspect of the jury instructions.
128 Beckering next argues that his trial counsel performed ineffectively by allowing the elements instructions to include language asking the jury to determine whether he acted as a party to the offense, including as a caretaker. Beckering argues that because a party to the offense and a caretaker are two different and unrelated concepts, the language used in the elements instructions created both uncertainties and inconsisten-cles in determining whether the jury had factually found that [Beckering] was a caretaker or a party to the offense. Beckering argues that his trial counsels acquiescence to the instructions wording constituted ineffective assistance.
129 To obtain relief based on ineffective assistance of counsel, Beckering must demonstrate prejudice, i.e., a reasonable probability that but for counsels errors, the result would have been different. Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). In the event it is easier to dispose of an ineffectiveness claim on the ground of lack of sufficient prejudice, we will do so without analyzing whether counsels performance was professionally unreasonable." Archuleta v. Galetka, 2011 UT 73, ¶41, 267 P.3d 232 (quoting Strickland, 466 U.S. at 697, 104 S.Ct. 2052). Here, we proceed directly to the prejudice prong of Beckerings ineffective assistance claim.
180 Beckering argues that, due to the nature of the alleged jury instruction error, we should either presume prejudice or require the State to establish lack of prejudice. However, none of the cases that Beck-ering cites in support of this argument arose in the context of an ineffective assistance of counsel claim. See Alleyne v. United States, -- U.S. --, 133 S.Ct. 2151, 186 L.Ed.2d 314 (2013); Neder v. United States, 527 U.S. 1, 119 S.Ct. 1827, 144 L.Ed.2d 35 (1999); Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967); State v. OBannon, 2012 UT App 71, 274 P.3d 992; State v. Pearson, 1999 UT App 220, 985 P.2d 919. To show prejudice in the ineffective assistance of counsel context, the defendant bears the burden of proving that counsels errors actually had an adverse effect on the defense and that there is a reasonable probability that, but for counsels errors, the result of the proceeding would have been different. State v. Munguia, 2011 UT 5, ¶30, 253 P.3d 1082 (citation and internal quotation marks omitted); see also State v. Cruz, 2005 UT 45, ¶ 18, 122 P.3d 543.
1 831 Beckering fails to articulate a persuasive explanation of how removing or altering the language as a party to the offense, including as a caretaker from the elements instructions could reasonably have led to a more favorable result for him at trial. Beck-ering argues that being a party to the offense was not the same as being a caretaker, but he ignores the instructions use of the word including as a bridge between the two seemingly unrelated terms. The entire phrase as a party to the offense, including as a caretaker can reasonably be read to mean simply as a party to the offense, with the language including as a caretaker included to remind the jury that caretaker status would not preclude convietion so long as the other elements of the offense were satisfied. If other plausible readings of the language exist, Beckering neither identifies them nor explains their relevance to the prejudice analysis.
1 32 Beckering has failed to show prejudice arising from the inclusion of the language as a party to the offense, including as a caretaker in the elements instructions. According ly, he has failed to carry the heavy burden of establishing an ineffective assistance of counsel claim. See State v. Lenkart, 2011 UT 27, 125, 262 P.3d 1. We therefore reject his ineffective assistance of counsel claim relating to the challenged language.
1383 Beckering also argues that his trial counsel permitted the jury instructions to incorporate two mental states into the same charged offense. Beckering argues that the elements instruction for reckless aggravated abuse of a vulnerable adult required the jury to find that he acted both recklessly and intentionally.
34 Beckering contends that the reckless aggravated abuse instruction improperly tasked the jury to find both (1) that Mr. Beckering was a party to the offense (which required an intentional mental state), and (2) that the defendant did so recklessly (which required a reckless mental state). He also argues that the instruction failed to adequately link the different mental states to the individual elements to which they applied. He further argues that, due to the conflicting mental standards, the crime, as decided by the jury, is a legal impossibility.
1135 We do not address these arguments on their merits because they allege errors that were invited below. Instead, Beckering must demonstrate that trial counsels failure to correct the alleged errors constituted ineffective assistance of counsel. To do so, Beckering must establish both deficient performance by counsel and resulting prejudice. See Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). However, his brief does not address either the objective reasonableness of counsels failure to object to the instructions or the likelihood of a different result for Beckering had counsel objected. We will not conduct that analysis on Beckerings behalf. See State v. Robison, 2006 UT 65, ¶21, 147 P.3d 448 {noting that the appellant bears the burden of persuasion on appeal and that an appellate court will not do the heavy lifting for the appellant).
136 We note, however, that the instructions inclusion of both recklessness and party-to-the-offense concepts does not appear to present any inherent error. Utah courts have concluded that accomplice-ie., party to the offense-liability can attach to offenses requiring a reckless mental state. In State v. Jeffs, 2010 UT 49, 243 P.3d 1250, the Utah Supreme Court explained that intent as used in the accomplice liability context is a legal term of art that means the state of mind accompanying an act. It should not be confused with the mental state designated as intentionally. Id. ¶43 (alteration in original) (citation omitted). Rather, accomplice liability adheres only when the accused acts with the mens rea to commit the principal offense. Id. (citation and internal quotation marks omitted); see also State v. Briggs, 2008 UT 75, ¶14, 197 P.3d 628 ([It is not necessary for the accomplice to have the same intent that the principal actor possessed as long as the accomplice intended that an offense be committed.); State v. Binkerd, 2013 UT App 216, ¶¶24-29, 310 P.3d 755. Reading the jury instructions in light of Jeffs, the elements instruction properly informed the jury that it could convict Beckering of aggravated abuse of a vulnerable adult if it found that Beckering had acted with the intent of recklessness. See Jeffs, 2010 UT 49, ¶ 43, 243 P.3d 1250.
187 Beckering has not shown deficient performance of trial counsel or resulting prejudice relating to the elements instructions inclusion of both reckless and party to the offense. He has therefore not established ineffective assistance of counsel arising from the instructions use of those terms.
IL Prosecutorial Misconduct
138 Beckering also contends that the States prosecutorial misconduct entitles him to a new trial. Beckering argues the State solicited inappropriate witness opinion, together with other improperly admitted evidence, from the detective who interviewed Beckering after Victims death. Beckerings counsel did not object to this testimony, and Beckering raises the issue as an ineffective assistance of counsel claim. Beckering also argues that the district courts failure to intervene to prevent or strike the testimony constitutes plain error. See State v. Dunn, 850 P.2d 1201, 1208 (Utah 1998) (explaining that the doctrine of plain error requires an appellant to show that an error exists, that the error should have been obvious to the trial court, and that the error is harmful).
139 During its direct examination of. the detective who interviewed Beckering, the State elicited testimony that the detective did not believe that Beckering could have been unaware of the abuse occurring in his house. Beckering identifies some seven questions and answers that he deems objectionable. For example, Beckering points to the following exchange:
Q: At this point, did you again confront the defendant, so to speak, with the actual conditions that [Victim] was living in, and how it was possible [Beckering] may not have known it, and ... what kind of information you gave to him to confront him with that statement?
A: Basically towards the end of the interview, admittedly Im getting frustrated with how somebody can live in a home, a small home, and not hear or see things that are going on in the home or be aware of it or have questions about whats going on in your own home, and I go over the autopsy, what we found, the conditions of the zip ties in the closet, that sort of thing, and you know, how somebody could not be aware of whats going on, and basically again he just, you know, he doesnt go upstairs, he doesnt do anything to interact with her, has basically no clue about whats going on in the home in regards to [Vice-tim]. The information he was getting was coming from [Wife] and [Shepard].
The detective expressed his frustration with Beckerings answers at least five times, as well as stating, [Mly belief was, I was having a hard time understanding how somebody could not know that that was happening in the home, being in that close proximity. At least twice, the detective characterized Victims treatment as torture, stating that basically shes been tortured in the closet and expressing his belief that when somebodys being tortured to the amount that {Vietim] was being tortured, ... everybody in that home wouldve known.
1] 40 Beckering raises numerous legal theories to explain how these questions and answers implicate plain error and ineffective assistance of counsel. He argues that the State repeatedly and improperly elicited the detectives opinion and feelings about whether Beckering was telling the truth. See State v. Burk, 839 P.2d 880, 883 (Utah Ct.App.1992) (Evidence is unfairly prejudicial{ ] if it has a tendency to influence the outcome of the trial by improper means, ... or otherwise causes a jury to base its decision on something other than the established propositions of the case. (citation and internal quotation marks omitted)). He argues that the States questions asked the detective to comment on the veracity of Beckerings statement, see State v. Davis, 2013 UT App 228, ¶ 38, 311 P.3d 538, and that the answers constituted improper expert testimony about Beckerings credibility, see State v. Perea, 2013 UT 68, ¶40, 322 P.3d 624. He also argues that the answers constituted improper expert testimony about Beckerings mental state. See Utah R. Evid. 704.
T41 Beckerings authorities are distinguishable from the instant case. For example, State v. Davis, 2013 UT App 228, 311 P.3d 538, held that a prosecutor asking a defendant whether another witness was lying was inappropriate because [sluch a question is argumentative and seeks information beyond the defendants competence. Id. ¶¶ 37-38. Here, the State did not ask the detective whether he believed Beckering was telling the truth during the interview.
{42 The detectives testimony also does not resemble that in cases where courts have found that an expert improperly testified as to a witnesss veracity. For example, in State v. Nelson, 777 P.2d 479 (Utah 1989), the Utah Supreme Court reversed a convietion after a family therapist opined that the victim was telling the truth at the time [the therapist] interviewed him. Id. at 481. Similarly, State v. Van Matre, 777 P.2d 459 (Utah 1989), reversed the conviction of a defendant convicted after an expert testified that children who describe sexual conduct are usually telling the truth and that [elhildren typically dont lie Id. at 461 (alteration in original).
43 Here, the detectives testimony never directly asserted that Beckering was lying during the interview. Nor did the detective testify that he could detect dishonesty or that Beckering was being dishonest. Instead, the detective, as part of describing the interview, commented on why he continued to ask Beckering about the abuse despite Becker-ings repeated denials. Beckering also fails to identify any way in which the State took undue advantage of the allegedly objectionable aspects of the detectives testimony to argue for his conviction.
1 44 Beckering also argues that the detectives multiple uses of the word tortured constituted improper comments meant to inflame passion or prejudice in the jury. See Boyle v. Christensen, 2011 UT 20, ¶ 18, 251 P.3d 810. In Boyle, the Utah Supreme Court concluded that defense counsels reference to the McDonalds coffee case in front of a civil jury was improper because it would seem to have the sole purpose of recalling the public outrage over isolated elements of the [McDonalds] case-thus improperly appealing to a jurys passions. Id. 22. In this case, we are not convineed that the isolated references to torture had the sole purpose of creating outrage or improperly appealing to [the] jurys passions. See id.
145 However, even assuming impropriety in the detectives questioning and testimony, Beckering cannot establish either ineffective assistance of counsel or plain error if there was a conceivable strategic reason for Beckerings counsel to allow the questioning without challenge. The Utah Supreme Court has instructed that if the challenged act or omission might be consid-, ered sound trial strategy, we will not find that it demonstrates inadequacy of counsel. State v. Dunn, 850 P.2d 1201, 1225 (Utah 1993). Similarly, [pllain error does not exist when a conceivable strategie purpose exists to support the use of the evidence. State v. Bedell, 2014 UT 1, 1 26, 822 P.3d 697 (citation and internal quotation marks omitted). The district court should take measures to avoid interfering with potential legal strategy or creating an impression of a lack of neutrality. Id.
T 46 There were conceivable strategie reasons for Beckerings counsel to let the detectives testimony proceed without objection. The detectives testimony afforded Beckering the opportunity to present his side of the story to the jury without taking the witness stand and subjecting himself to cross-examination. It was reasonable trial strategy to allow the detective to describe his multiple expressions of frustration and disbelief so that the jury could hear Beckerings repeated and strenuous denials in the face of strong questioning.
147 Similarly, there were justifiable reasons for trial counsel not to object to the detectives description of Victims treatment as torture. Objecting to the isolated references could have been viewed by the jury as-an attempt to minimize Victims suffering. It was sound trial strategy not to contest the States characterization of the abuse but to ask the jury to blame that abuse entirely on Wife and Shepard.
148 In combination, both aspects of the detectives testimony played into Beckerings ultimate trial strategy, which was to acknowledge the severity of Victims treatment while asking the jury to focus on the evidence presented at trial and find that Beckering did not know about the abuse. Indeed, Becker-ings counsel referred to both aspects of the detectives testimony in his closing argument, stating,
[The detective testified,] I dont believe him. You have to know whats going on in your house. Time after time after time, parents dont know that their teenagers are cutting school and hanging out in the house. Time after time after time, they dont know their teenagers are having sex, doing drugs.
... .[T)he real question is, did he know that he had to do something? You heard from the evidence that from December to March, he didnt want anything to do with her. He stayed away from her. Because he was seared of her. He was afraid of the problems. Its as he said to the officers, when he found out-when they said, shes been tortured.
Shes been tortured?
Yes, and thats putting it mildly.
Oh my God, were his words. He said, I wish I wouldve gone up there more. Because maybe he couldve done something about it.
Thus, Beckerings counsel actually made use of both the detectives statements of disbelief and the references to torture in arguing for Beckerings acquittal.
¶49 Because counsels decision to refrain from objecting to the States examination of the detective could be considered a reasonable trial strategy, that lack of objection cannot support a claim of ineffective assistance of counsel. See State v. Lee, 2014 UT App 4, ¶17, 318 P.3d 1164. For the same reason, the district court did not commit plain error by refusing to intervene in the States questioning. See Bedell, 2014 UT 1, ¶26, 322 P.3d 697 (A district court is not required to constantly survey or second-guess [a] nonobjecting partys best interests or trial strategy and is not expected to intervene in the proceedings unless the evidence would serve no conceivable strategic purpose. (alteration in original) (citation and internal quotation marks omitted)).
CONCLUSION
150 Beckering has failed to demonstrate that he received ineffective assistance of counsel at trial. He has also failed to establish that the alleged prosecutorial misconduct and improper testimony constituted plain error. We therefore affirm his conviction of aggravated abuse of a vulnerable adult.
. The jurys fact-finding role in this regard was further emphasized by separate instructions providing definitions of terms including vulnerable adult and caretaker.
. We note that in Alleyne v. United States, - U.S. --, 133 S.Ct 2151, 186 L.Ed.2d 314 (2013), the Supreme Court expressed no discomfort with the verdict form the jury used to find that the defendant had [ulsed or carried a firearm during and in relation to a crime of rar violence, notwithstanding the multiple factual determinations contained in that single finding. Id. at 2156 (alteration in original).
. This reading of the challenged language is consistent with the language and structure of Utah Code section 76-5-111, which defines the crime of aggravated abuse of a vulnerable adult and provides for two separate theories of criminal liability. See Utah Code Ann. § 76-5-111(2) (LexisNexis 2012). Section 76-5-111(2) provides for criminal penalties against any person, including a caretaker, who causes serious physical injury to a vulnerable adult under circumstances likely to produce death or serious physical injury. See id. Section 76-5-111(2) also provides for criminal liability for a person who, having the care or custody of a vulnerable adult, causes or permits the vulnerable adult to be injured or placed in a situation where her person or health is endangered. See id. The statutory language including a caretaker appears to be intended to clarify that, while only a caretaker can be liable for caus[ing] or permit{ting] the harm identified in the second theory of liability, any person, including a caretaker can be liable under the first theory by causling] a vulnerable adult to suffer serious physical injury. See id. (emphasis added). The State charged Beckering under both theories of liability and, like the statute, the elements instructions at his trial clarified that only the causes or permits theory required a jury finding that Beckering was Victims caretaker.
. The jury received a separate instruction defining the concept of party to the offense or accomplice liability. That instruction stated, among other things, that Beckering could not be convicted as an accomplice unless he had the intent that the underlying crime be committed, he intended to aid the principal actor(s) in the offense, and he intentionally aid[ed] in the commission of the crime.
. For example, it would likely have been improper for the State to suggest to the jury that the detectives experience made him an excellent judge of credibility and that if he did not believe Beckering then the jury should not believe him either. But Beckering points us to no such explicit improper use of the detectives testimony.
