Opinion
ORME, Judge:
¶ 1 Defendant James Gray appeals his convictions on one count of sodomy on a child, three counts of sexual abuse of a child, and one count of object rape of a child. We affirm.
BACKGROUND
¶ 2 In 1999, the victim told her mother that Defendant had sexually abused her since she was six years old. The victim's mother called a family member but did not call the police. A few months later, the vietim told a friend about the abuse, and her friend suggested that she talk with a teacher or school counselor. The next day, the victim talked to her school counselor, who called the police.
¶ 3 Defendant was subsequently charged with one count of sodomy on a child, three counts of sexual abuse of a child, and one count of object rape of a child for conduct that occurred "on or about November 1, 1991 to October 81, 1997."
¶ 4 At trial, the victim testified that the first instance of abuse occurred in 1990 or 1991, when she was around seven years old, and that "it was sunny outside." Defendant called to the victim from inside his bedroom to get him a drink, The victim went to Defendant, who was lying on his bed in his underwear, and he said "he wanted to show [her] something." When the victim got onto the bed, Defendant "took [her] hand and put it down to his penis" under his underwear, and he "(showed her]} how to move up and down."
¶ 5 The victim also testified to another instance of abuse that occurred right before a vacation to Disneyland when she was around twelve years old. At that time, the victim was sleeping in her living room. Around two or three o'clock in the morning, Defendant started touching the victim's breasts over her pajamas, asking her to wake up and calling her name. Defendant also reached down and touched the victim's vagina over her pajamas. This touching lasted for about ten minutes while the victim stayed still and pretended to be asleep.
¶ 6 Another time, when the victim was around eleven or twelve years old, Defendant told her that he wanted to show her something, and he produced a pink dildo. The victim testified that Defendant rubbed the dildo on her breast and then applied a lubricant to the dildo. Defendant then put the dildo "on the outside of [her] vagina." When she asked Defendant to stop, he stopped and said he was sorry. However, Defendant proceeded to pull out a bottle of "strawherry flavored" liquid, which he put on her breasts and then licked off. The victim testified that this was the only time Defendant touched her with the dildo.
¶ 7 Also, when the victim was still eleven or twelve years old, Defendant joined her in the shower and "told [her] to put [her] one
leg up to the side of the tub." Defendant, who was naked, sat down in the tub and told her to hold onto his head while he licked her vagina for around ten minutes. This happened again onee or twice.
¶ 8 The victim further testified that while her family's house was being remodeled, she was in the living room watching a movie when Defendant started to massage her breasts and vagina over her clothing from behind. Defendant asked her if she was aroused, and because she "didn't know exactly what [that] meant," she said, "No."
¶ 9 Finally, the victim testified that, at periodic intervals, Defendant sexually abused her "[albout three times a week" from the time she was seven and that the abuse stopped only after a mutual acquaintance talked to Defendant in the fall of 1997. She also testified that she remembered "flashes" of events. For example, the victim testified that Defendant's penis "sometimes" touched her vagina, "but it never went in." Defendant's fingers went inside her vagina "[olnce or twice," and "it felt really uncomfortable" and "like a little burning." Defendant also told her that "he was teaching [her] how to please [her] husband when [she] would be getting married."
¶ 10 Soon after police learned of the sexual abuse, the victim was examined by a pediatrician, who later testified as an expert witness. At trial, the pediatrician testified about her examination of the victim. Specifically, the pediatrician testified that the victim told her that Defendant had touched her with his hands and his penis, tried to insert his penis into her vagina, and tried to insert his fingers into her vagina. The victim also told the pediatrician that, while "there had been pain," there "had not been bleeding."
¶ 11 The pediatrician testified to taking a behavioral history of the victim, which showed that the victim exhibited signs of depression, that the victim had been missing school and was angry, that she did not seem interested in much of anything, and that she had problems with her appetite when she was younger. The pediatrician testified that "[the different things described in the behavioral history could all have been caused by sexual abuse." She clarified, however, that "the behavioral changes are not specific to sexual abuse [and other] things could cause them [as] well." The pediatrician also conducted a physical examination of the vie-tim and testified that, while the "entire exam was normal," "a normal exam fits the history" the vietim gave.
¶ 12 On cross-examination, defense counsel confirmed with the pediatrician that she had given child abuse talks throughout Utah to prosecutorial offices, that she had been in court around two hundred times, and that about ninety percent of the time she testified for the prosecution. Defense counsel also asked the pediatrician how she came to her conclusions and if she "took [the victim's] word" in making her conclusions, to which the pediatrician replied, "I felt that she interviewed honestly. I took her word and added to that the behavioral changes that existed."
¶ 13 Defendant testified at trial and denied the allegations of sexual abuse. He testified that he found out that the victim was forging checks on his account, the implication being that the claims of sexual abuse were made in retaliation for his expressed anger. At trial, the victim admitted to writing one check on Defendant's account and signing Defendant's name, but she insisted this was done with his permission.
¶ 14 After the State rested its case, Defendant moved to dismiss the charges against him on the basis that there was insufficient evidence to permit the jury to deliberate. The trial court denied the motion and ruled that there was "some evidence as to each element of each count" and that the jury needed to decide the issues. The jury convicted Defendant on all counts. He now appeals.
ISSUES AND STANDARDS OF REVIEW
¶ 15 Defendant raises several issues on appeal. First, Defendant argues that the evidence was insufficient to convict him of sexual abuse of a child.
Second, Defendant argues that the evidence was insufficient to support his conviction of object rape of a child.
When a defendant challenges a jury verdict on the ground that the evidence is insufficient, "[we review the evidence and all inferences which may reasonably be drawn from it in the light most favorable to the verdict." State v. Hirschi, 2007 UT App 255, ¶ 15, 167 P.3d 503 (alteration in original) (citation and internal quotation marks omitted). "We reverse ... only when the evidence, so viewed, is sufficiently inconclusive or inherently improbable that reasonable minds must have entertained a. reasonable doubt that the defendant committed the crime of which he was convicted." Id. (omission in original) (citation and internal quotation marks omitted).
¶ 16 Defendant next contends that the trial court erred in allowing the pediatrician to testify that the victim was honest during her medical exam. "Because [D]efendant failed to raise this issue below, we review his claim for plain error." State v. Baker, 963 P.2d 801, 803 (Utah Ct.App.1998).
¶ 17 Defendant also argues that the prosecutor committed misconduct by referencing uncharged conduct during his opening statement. ."We review a trial court's handling of claimed prosecutorial misconduct for an abuse of discretion." State v. King, 2010 UT App 396, ¶ 13, 248 P.3d 984. However, timely objections to particular statements were not made below, Defendant must establish either plain error or ineffective assistance of counsel to merit reversal." State v. Clark, 2014 UT App 56, ¶ 10, 322 P.3d 761.
¶ 18 Defendant's final argument is that his trial counsel provided ineffective assistance when he failed to object to the pediatrician's testimony regarding the victim's truthfulness. "An ineffective assistance of counsel claim raised for the first time on appeal presents a question of law." State v. Pedersen, 2010 UT App 38, ¶ 9, 227 P.3d 1264 (citation and internal quotation marks omitted).
ANALYSIS
I. Sufficiency of Evidence
A. Sexual Abuse of a Child
¶ 19 Defendant first claims that the evidence was insufficient to support his con
viction for sexual abuse of a child. A person commits sexual abuse of a child if,
under cireumstances not amounting to rape of a child, object rape of a child, sodomy on a child, or an attempt to commit any of these offenses, the actor touches the anus, buttocks, or genitalia of any child, [or] the breast of a female child.
Utah Code Ann. § 76-5-404.1(2) (LexisNexis Supp.2014).
¶ 20 In this case, the jury instructions permitted the jury to find that Defendant committed sexual abuse of a child only if it concluded that such abuse occurred "on or about November 1, 1991 through October 31, 1997." At trial, the victim testified that the first instance of abuse occurred in 1990 or 1991 when she was around seven years old and "it was sunny outside." Defendant argues that the victim turned seven on December 18, 1990, and that "the State was required to prove that [Defendant] had engaged in a sekual act with a child after November 1, 1991." Thus, Defendant argues, because the victim was only seven years old for a few weeks after November 1, 1991, during a time of year when it is not typically sunny, and because she did not remember the exact date of the abuse, her "testimony regarding her age and the weather at the time of [the] alleged abuse makes it very likely that any alleged conduct occurred early on in her seventh year, outside the charged period."
¶ 21 In determining whether the evidence was sufficient to support the jury's verdict, we do not "sit as a second trier of fact." State v. Boyd, 2001 UT 30, ¶ 16, 25 P.3d 985. "It is the exclusive function of the jury to weigh the evidence and to determine the credibility of the witnesses. So long as there is some evidence, including reasonable inferences, from which findings of all the requisite elements of the crime can reasonably be made, our inquiry stops." Id. (emphasis in original) (citation and internal quotation marks omitted).
¶ 22 Here, the jury was presented with some evidence of each element of sexual abuse of a child during the charged period. See id.; State v. Mead, 2001 UT 58, ¶¶ 66-67, 27 P.3d 1115 (concluding that the evidence was sufficient to uphold the defendant's conviction for criminal solicitation where the only evidence to support the jury's verdict was testimony from a single witness). First, the victim testified that "around" 1990 or 1991, when she was "[alround seven," Defendant made her touch his penis under his underwear. But more importantly, she testified that when Defendant was around, he sexually abused her "[albout three times a week" from the time she was seven and that the abuse did not stop until after a mutual acquaintance talked to Defendant in the fall of 1997.
Thus, even if the victim was mistaken as to when the abuse started, her testimony as to other instances of sexual abuse places multiple instances of abuse well within the charged period.
¶ 23 Although Defendant denied having ever abused the victim, the jury's apparent décision to give the victim's testimony "significant weight and credibility was within the prerogative of the trier of fact." See State v. Wilkerson, 612 P.2d 362, 365 (Utah 1980). From the victim's testimony, the jury could properly conclude that Defendant's conduct satisfied all of the elements of sexual abuse of a child, see Utah Code Ann. § 76-5-404.1(2), and that at least one incident of abuse occurred within the requisite time frame, i.e., in the period between approximately November 1, 1991, and October 31, 1997. Because it was within the jury's prerogative to so find, we conclude that the evidence was sufficient to convict Defendant of sexual abuse of a child.
B. Sodomy on a Child
¶ 24 For essentially the same reason, we conclude that there was sufficient evi
dence to convict Defendant of sodomy on a child. A person commits sodomy on a child if "the actor engages in any sexual act upon or with a child who is under the age of 14, involving the genitals or anus of the actor or the child and the mouth or anus of either person, regardless of the sex of either participant." Utah Code Ann. § 76-5-408.1(1).
¶ 25 Here, the jury was presented with some evidence of each element of sodomy on a child. See State v. Boyd, 2001 UT 30, ¶ 16, 25 P.3d 985. The victim testified that when she was eleven or twelve, Defendant, who was naked, joined her in the shower and "lick[ed her] vagina" for ten minutes. The victim stated that she remembered this particular time that Defendant performed oral sex on her "because it was the first time it ever happened to [her]," and "It felt ... really weird that time." She also testified that Defendant did it again "once [or] twice."
¶ 26 Based on the victim's testimony, the jury could properly find that Defendant's conduct satisfied all of the elements for sodomy on a child. See Utah Code Ann. § 76-5-408.1(1). We see no reason to second guess the jury's determination and, therefore, we conclude that the evidence was sufficient to convict Defendant on the charge of sodomy on a child.
C. Object Rape of a Child
¶ 27 Defendant next claims that the evidence was insufficient to support his conviction for the crime of object rape of a child, Specifically, Defendant argues that the State failed to prove "penetration, however slight," under section 76-5-402.8 of the Utah Code. Defendant was charged under the 1995 version of the Utah Code. Under that version, a person committed object rape of a child when the person
cause[d] the penetration, however slight, of the genital or anal opening of. a child who [was] under the age of 14 by any foreign object, substance, instrument, or device, not including a part of the human body, with intent to cause substantial emotional or bodily pain to the child or with the intent to arouse or gratify the sexual desire of any person....
Utah Code Ann. § 76-5-402.3 (Michie 1995). At trial, the victim testified that Defendant put a dildo "on the outside of [her] vagina." According to Defendant, under State v. Simmons, 759 P.2d 1152 (Utah 1988), the State must have proven that the object in question was at least "between the outer folds of [the victim's] labia" during the incident to constitute penetration. Id. at 1154. Defendant argues that because the victim testified that Defendant put the dildo "on the outside" of her vagina, the State could not have proven that the dildo was between the folds of her labia.
¶ 28 In Simmons, the defendant was convicted of rape of a child based on the child's testimony that the defendant had "put the tip of his penis 'on' her labia." Id. at 1153-54. On appeal, the defendant argued that the evidence was insufficient to sustain his conviction because there was no showing of penetration as required under the version of the law then in effect, see Utah Code Ann. § 76-5-407(2) (Allen Smith Supp.1985), and the Utah Supreme Court agreed, see Simmons, 759 P.2d at 1153-54. The Supreme Court noted that the "generally accepted rule is that entry between the outer folds of the labia is sufficient to constitute 'penetration' as that term is commonly used in defining the crime of rape." Id. at 1154. Therefore, the child's testimony in Simmons that the defendant "put the tip of his penis 'on' her labia" was insufficient to constitute even slight penetration, and the Supreme Court reversed the defendant's conviction for rape of a child. Id. at 1154-55.
¶ 29 Defendant's reliance on Simmons is misplaced. At the time Simmons was decided, the relevant section of the Utah Code, which defined " '[p]enetration' or 'touching' sufficient to constitute [the] offense," provided, "In any prosecution for unlawful sexual intercourse, rape, or sodomy, any sexual penetration or, in the case of sodomy, any touching, however slight, is sufficient to constitute the offense," Utah Code Ann. § 76-5-407(2) (Allen Smith Co. Supp.1985). Thus, to be clear, "sexual penetration" was required for most offenses, though "any touching" was sufficient for a sodomy charge. See id. But section 76-5-407(2) has since been amended. In 1989, the Utah Legislature added "rape of
a child, or object rape of a child" to the crimes for which "any touching, however slight" was "sufficient to constitute the relevant element of the offense." See. Act of Feb. 16, 1989, ch. 285, § 2, 1989 Utah Laws 765, 765 (codified at Utah Code Ann. § 76-5-407(2) (Michie Supp.1989)). Thus, at the time Defendant committed his crime, the law provided, "In any prosecution for unlawful sexual intercourse, rape, rape of a child, object rape of a child, or sodomy, any sexual penetration or, in the case of sodomy, rape of a child, or object rape of a child any touching, however slight, is sufficient to constitute the relevant element of the offense." Utah Code Ann. § 76-5-407(2) (Michie 1995) (emphasis added). "Penetration" as defined in Simmons, i.e., "entry between the outer folds of the labia," see 759 P.2d at 1154, was no longer required to commit the offense of object rape of a child; rather, "any touching, however slight" was all that was necessary to constitute the offense, see Utah Code Ann. § 76-5-407(2) (Michie 1995).
¶ 30 At trial, the vietim testified that when she was around eleven or twelve years old, Defendant took out a pink dildo and first rubbed it on her breast. He then applied a lubricant to the dildo and put the dildo "on the outside of [her] vagina." Because "entry between the outer folds of the labia" was no longer required to commit the offense of object rape of a child at the time Defendant put the dildo on the outside of the victim's vagina, Defendant's act was sufficient to establish the requisite "touching, however slight" under section 76-5-407(2) of the Utah Code. As such, Defendant's act was sufficient to constitute the element of "penetration" under the object rape of a child statute then in effect. See Utah Code Ann. § 76-5-402.3 (Michie 1995). We therefore conclude that there was sufficient evidence to support Defendant's conviction for object rape of a child.
II. Expert Testimony
¶ 31 Defendant also claims that the trial court erred in allowing the State's medical expert, the pediatrician who examined the victim, to testify regarding the victim's truthfulness, in violation of rule 608(a) of the Utah Rules of Evidence.
At trial, Defendant's counsel pursued the following line of questioning during cross-examination:
[Defense Counsel]: Simply tell me, if there is nothing to show that this young lady has any physical evidence to show that she has been sexually abused-now, I said physical-how do you arrive to the conclusion that she was sexually abused?
[Pediatrician]: The diagnosis is based on her interview, the statements that she makes, the behavioral changes that are consistent with sexual abuse, the well known fact that 80 percent or more of child sexual abuse cases have normal physical examinations and that physical findings are not the way to make the diagnosis.
[Defense Counsell: But you're not a psychiatrist and you're not a psychologist, so all we have here really comes down to the barest of points, is the fact that you took her word to make your conclusion. Whatever [the victim] told you, you took her word?
[Pediatrician]: I felt that she interviewed honestly. I took her word and added to that the behavioral changes that existed.
Defense counsel did not object to the pediatrician's statements, which were, after all, made in response to his questions.
¶ 32 Generally, "claims not raised before the trial court may not be raised on appeal," and we will not consider them unless "exceptional cireumstances exist or plain error occurred." State v. Holgate, 2000 UT 74, ¶ 11, 10 P.3d 346 (citations and internal quotation marks omitted). Defendant argues the applicability of the plain-error exception to the preservation rule. But under the doe-trine of invited error, Utah courts "have declined to engage in even plain error review when counsel, either by statement or act, affirmatively. represented to the [trial] court
that he or she had no objection to the [proceedings]." State v. Winfield, 2006 UT 4, ¶ 14, 128 P.3d 1171 (alterations in original) (citation and internal quotation marks omitted). The invited-error doctrine "prohibits a party from setting up an error at trial and then complaining of it on appeal." State v. Layman, 953 P.2d 782, 785 (Utah Ct.App.1998) (citation and internal quotation marks omitted).
¶ 33 For example, in In re E.D., 876 P.2d 397 (Utah Ct.App.1994), both parents appealed an order terminating their parental rights. Id. at 398. At trial, two therapists testified that they believed the children had been sexually abused. See id. at 402. On appeal, the parents argued, among other things, "that it was improper for the court to consider testimony bearing upon the perceived credibility of the children." Id. at 401. Specifically, the parents argued that the trial court improperly permitted the testimony of the two therapists, who testified "that they believed the children were telling the truth about being sexually abused." Id. at 402. Because the parents had not objected to this testimony at trial, this court determined that the parents had waived the issue. Id. Moreover, during trial, "counsel for the parents asked three witnesses whether they thought the children were credible." Id. (emphasis in original). Accordingly, this court concluded that "even if it were error to admit the testimony, it was "invited error{[,] which is viewed with disfavor in Utah." Id.
¶ 34 Similar to In re E.D., the pediatri-clan's statement concerning the victim's truthfulness was in direct response to a line of questioning by Defendant's counsel. Defense counsel asked the pediatrician how she arrived at her conclusion and whether she "took [the victim's] word" in her evaluation, and thus, Defendant elicited the very testimony he now protests. Accordingly, we conclude that even if it were error to admit the pediatrician's testimony, it was invited error. Under the invited-error doctrine, Defendant is prohibited from now complaining of an alleged error that he set up. See Layman, 953 P.2d at 785. Accordingly, we decline to further address this argument.
III. Prosecutorial Misconduct
¶ 35 Defendant next argues that the prosecutor engaged in misconduct during his opening statement when he made several references to uncharged, alleged instances of sexual abuse of the victim.
¶ 36 A prosecutor's remarks
constitute misconduct meriting reversal if they "call to the attention of the jurors matters they would not be justified in considering in determining their verdict and ... the error is substantial and prejudicial such that there is a reasonable likelihood that in its absence, there would have been a more favorable result for the defendant."
State v. Maestas, 2012 UT 46, ¶ 159, 299 P.3d 892 (omission in original) (quoting State v. Tillman, 750 P.2d 546, 555 (Utah 1987)). "In assessing whether allowing the prosecution's comments was a harmful error, 'we will consider the comments both in context of the arguments advanced by both sides as well as in context of all the evidence."" Id. (quoting State v. Bakalov, 1999 UT 45, ¶ 56, 979 P.2d 799). However, failure to object to the prosecution's improper remarks at trial "waives the claim unless the remarks reach the level of plain error." State v. Palmer, 860 P.2d 339, 342 (Utah Ct.App.1993). Defendant failed to raise timely objections to the prosecutor's opening remarks at trial, and so he argues that the plain-error exception to the preservation rule applies.
¶ 37 To establish plain error, Defendant must show that "G) [aln error exists; (i) the error should have been obvious to the trial court; and (iii) the error is harmful, ie., absent the error, there is a reasonable likelihood of a more favorable outcome for the appellant." State v. Dunn, 850 P.2d 1201, 1208 (Utah 1993).
¶ 38 Defendant points out that he was charged for conduct "that occurred between November 1991 through October 31, 1997." But during his opening statement, the prosecutor made three references to alleged abuse for which Defendant had not been charged. Specifically, during his opening statement, the prosecutor said:
Now, [the victim] doesn't have exact dates as to when [the abuse] started or when it
ended and that's why the Information that was just read says from November 2, 1991 through October 31st of 1997. The abuse started when she was six. In fact that was 1989. And the allegation is from 1991. Because of [the] statute of limitations, [the] State can only file charges that go back eight years. This case was filed in ... October of 1999. So we go back eight years from there.
The prosecutor also remarked, "And as I indicated, from the time she was six years old to 1997 this type of abuse happened." Finally, the prosecutor told the jury, "You have heard about the six charges. I have explained to you the statute-of-limitation reason why we're not going back to 1989, but going to 1991."
1 39 Each of these statements referred to alleged conduct for which Defendant had not been charged because the conduct was outside of the period specified in the charging document. Defendant therefore argues that "without the remarks there is a reasonable likelihood that [Defendant] would have secured a more favorable outcome" and that the "remarks compel a reversal of [Defendant's] conviction."
1 40 We agree with Defendant that it was inappropriate for the prosecutor to refer to the alleged pre-1991 conduct because it was uncharged and thus called the jurors' attention to matters they were not justified in considering in reaching their verdict,. See Maestas, 2012 UT 46, ¶ 159, 299 P.3d 892. But even assuming that the error should have been obvious to the trial- court, we disagree with Defendant that the requisite prejudice resulted from the prosecutor's statements.
See Dunn, 850 P.2d at 1208.
T 41 The evidence placing Defendant's conduct within the time period for which he was actually charged was overwhelming. Cf. State v. King, 2010 UT App 396, ¶ 35, 248 P.3d 984 (noting that "we more readily find errors to be harmless when confronted with overwhelming evidence of the defendant's guilt"). The jury heard testimony from the victim that Defendant made her touch his penis, that he touched her breasts and vagina, that he licked her breasts and vagina, that he touched a dildo to her vagina, that he touched his penis to her vagina, that he put his fingers in her vagina, and that he abused her "[albout three times a week" during periodic intervals spanning several years within the salient time period. See supre 91 4-9. There is nothing to suggest that the jury would have viewed Defendant more favorably had it thought the extensive abuse lasted a "mere" six years rather than eight or that it otherwise latched on to the prosecutor's statements and relied on them when it found Defendant guilty.
Accordingly, although it was inappropriate for the prosecutor to refer to the uncharged conduct, we conclude, beyond a reasonable doubt, that the prosecutor's statements were not so prejudicial as to warrant reversal.
IV. Ineffective Assistance of Counsel
142 Finally, Defendant, represented by new counsel on appeal, argues that his trial counsel was ineffective for "failing to object to ... [the pediatrician's] testimony" and for failing "to move to strike the testimony as unresponsive, inappropriate and inadmissible." To establish that he received ineffective assistance of counsel, Defendant must show "that counsel's performance was deficient" and "that the deficient performance prejudiced the defense." Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). "If a defendant fails to establish either of the two parts of the Strickland test, counsel's assistance was
constitutionally sufficient, and we need not address the other part of the test." State v. Medina-Juarez, 2001 UT 79, ¶ 14, 34 P.3d 187.
¶ 43 To demonstrate that counsel's performance was deficient, Defendant "must overcome the strong presumption that [his] trial counsel rendered adequate assistance, by persuading the court that there was no conceivable tactical basis for counsel's actions." State v. Clark, 2004 UT 25, ¶ 6, 89 P.3d 162 (emphasis and alteration in original) (citations and internal quotation marks omitted). Defendant's bare assertion that "[Inlo possible tactical reason existed for defense counsel to engage in such a deficient manner" does not overcome this presumption.
¶ 44 "[When viewing 'the variety of circumstances faced by defense counsel, a conscious choice not to object to arguably inadmissible testimony may, at times, fall within 'the range of legitimate decisions regarding how best to represent a criminal defendant.'" State v. Marble, 2007 UT App 82, ¶ 12, 157 P.3d 371 (quoting Strickland, 466 U.S. at 689, 104 S.Ct. 2052). Likewise, a defendant cannot establish that his counsel's performance was deficient under Strickland "by merely showing that counsel elicited arguably inadmissible testimony." Id. Rather, a defendant must still "overcome the presumption that, under the cireumstances, the challenged action might be considered sound trial strategy." Strickland, 466 U.S. at 689, 104 S.Ct. 2052 (citation and internal quotation marks omitted).
¶ 45 Upon reviewing the transcript of defense counsel's eross-examination of the pediatrician in conjunction with his closing argument, we can conceive of a sound tactic served by defense counsel's line of questioning. To begin with, it is reasonable to conclude that defense counsel elicited the pediatrician's testimony to call to the jury's attention that there was no independent physical evidence of abuse. After all, the pediatrician testified that she conducted a physical examination of the victim and that "[hler exam was normal."
¶ 46 In addition, defense counsel's line of questioning may well have been designed to highlight the fact that although the "things described in [the victim's] behavioral history could all have been caused by sexual abuse," the pediatrician readily conceded that "the behavioral changes [were] not specific to sexual abuse" and that "[olther things could [have] caused] them [as] well." Defense counsel also highlighted the fact that the pediatrician had been in court around two hundred times and that she had testified for the prosecution about ninety percent of the time, arguably calling into question her objectivity.
¶ 47 Moreover, defense counsel's strategy in eliciting the pediatrician's statements is illustrated by his closing argument, where he used the pediatrician's statements to question her reliability as an expert witness. Specifically, in closing argument, defense counsel stated:
The prosecutor wants you to give credence to an expert. The instructions tell you you don't have to. I cannot give credence to an expert who says I only teach prosecutors. I cannot give credence to an expert that says I base my findings on hearsay testimony that I did not even confirm myself, personally. I took for face value what was written and what was stated to me.
Based on defense counsel's questioning during cross-examination and his use of the pediatrician's answers during his closing argument, it is reasonable to conclude that defense counsel's line of questioning was designed to demonstrate that the pediatri-clan's testimony was not reliable. Accordingly, the record demonstrates that counsel had a conceivable tactical basis for eliciting the pediatrician's statement regarding the victim's truthfulness. We therefore conclude that Defendant has not shown that defense counsel's performance was deficient under the Strickland test. See 466 U.S. at 687, 104 S.Ct. 2052. Because Defendant has failed to establish deficient performance, "we need not address the [prejudice] part of the test." State v. Medina-Juarez, 2001 UT 79, ¶ 14, 34 P.3d 187.
CONCLUSION
48 We conclude that there was sufficient evidence to find Defendant guilty of both sexual abuse of a child and object rape of a child. We further conclude that any error committed by the trial court in allowing the pediatrician to testify regarding the victim's truthfulness was invited error. In addition, we conclude that the prosecutor's opening remarks were not so prejudicial as to warrant reversal. Finally, we reject the argument that Defendant received ineffective assistance of counsel at trial. We therefore affirm Defendant's convictions.
