THE PEOPLE,

Plaintiff and Respondent, G064423

v. (Super. Ct. No. 19NF1490)

GABRIEL AGUILLON, OPINION

Defendant and Appellant.

Appeal from a judgment of the Superior Court of Orange County, Michael J. Cassidy, Judge. Affirmed as modified. Joanna McKim, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Charles C. Ragland, Chief Assistant Attorney General, Arlene A. Sevidal, Assistant Attorney General, and Arlyn Escalante, Deputy Attorney General, for Plaintiff and Respondent. * * * Defendant Gabriel Aguillon was convicted of multiple counts involving the sexual abuse of his then eight-year-old niece. On appeal, he challenges the admission of one line of an expert witness’s testimony, and portions of the prosecutor’s closing argument, which he claims constitutes misconduct. We find no error. Aguillon also argues, and the Attorney General agrees, the abstract of judgment must be amended to make clear the trial court found an inability to pay fees and fines, and to provide the correct number of prejudgment credit days. We will instruct the trial court to make the necessary changes to the abstract of judgment. As so modified, the judgment is affirmed. FACTUAL AND PROCEDURAL BACKGROUND1 C.N. (the victim) is Aguillon’s niece. At the time of the incidents at issue here, she was between six and eight years old. The victim testified she loved and trusted Aguillon and was close to him; they lived in the same home (owned by the victim’s grandmother, Aguillon’s mother), and spent time together playing video games, watching movies, and going to the park. After the victim’s family moved out of her grandmother’s home, the victim continued to see Aguillon regularly. The victim’s mother would drop her off at her grandmother’s home during the day while her mother was at work.

Given the limited nature of the issues raised by Aguillon on 1

appeal, our presentation of the facts of the case is also limited.

2 The victim testified Aguillon did all of the following to her: touched her “inappropriately” on her upper thighs; touched her vagina underneath her clothes; grabbed her face and kissed her on the lips; touched her breasts over her clothes; showed her pornographic videos on his laptop computer and told her that “was going to be me and him”; pulled her onto his lap while sitting on his bed and watching pornographic videos, during which she could feel his penis; pulled his penis out of his pants and showed it to her, and then pushed her head toward it; and touched her vagina with his mouth and tongue. The victim underwent an examination by a sexual assault response team (SART) about two days after the last act of abuse by Aguillon. The SART examiner testified she would not expect to find injury on a child after two days because the anogenital area heals quickly. As part of the examination, DNA swabs were collected. The victim was interviewed by the Child Abuse Services Team (CAST) a few days after the last act of abuse. The victim told the CAST interviewer that Aguillon showed her a “disgusting” video, showed her his “private part,” touched and licked her “private part,” and placed his finger inside her “bottom.” She could feel his “private part” on her “bottom.” He also put his “private part” in her mouth and touched her breasts. The victim’s mother placed a covert call to Aguillon around this time, which was taped by the police. Although Aguillon initially denied everything, he ultimately admitted the victim had seen pornographic videos on his laptop, and that he had touched the victim’s vagina over her clothes. He claimed the victim had been looking up pornography on his laptop, and had taken advantage of him by placing his hand inside her pants, placing his penis in her mouth, and essentially forcing him to orally copulate her.

3 Aguillon was interviewed by the police shortly thereafter. He claimed the victim saw a web browser on his laptop which was open to a pornographic website and started asking him about oral sex. Aguillon claimed his eight-year-old niece “took advantage” of him by pulling his pants down while he was asleep and orally copulating him, so he began orally copulating her. No significant DNA findings were made, meaning there was no clear evidence of Aguillon’s DNA on the victim. A forensic scientist from the Orange County Crime Lab testified the lack of DNA on a victim does not mean that a sexual assault did not happen. She testified that the passage of time, bathing, or transferring DNA to another person can all affect whether or not DNA will be detected. An amended information charged Aguillon with two counts of oral copulation with a child 10 years old or younger (Pen. Code, § 288.7, subd. (b); counts 1, 2), digital penetration of a child 10 years old or younger (ibid.; count 3), and two counts of committing a lewd act on a child under 14 years old (§ 288, subd. (a); counts 4, 5). The information alleged as factors in aggravation that Aguillon took advantage of a position of trust, and the victim was particularly vulnerable. (Cal. Rules of Court, rule 4.421(a)(3), (11).) A jury found Aguillon guilty on all counts. In a bifurcated proceeding, the trial court found true the aggravating factors. The trial court sentenced Aguillon to 30 years to life: 15 years to life on counts 1, 2, and 3, and six years on counts 4 and 5. The sentence on count 3 was to run consecutively to the sentence on count 1, and counts 2, 4, and 5 were to run concurrently. The court found Aguillon had no ability to pay the criminal conviction and court operations fees. It imposed a restitution fine and parole revocation restitution fine of $300 each, and suspended the

4 latter. (Pen. Code, §§1202.4, subd. (b), 1202.45.) The court credited Aguillon with 1,829 actual custody days and 274 good conduct credit days, for a total of 2,103 credit days. Aguillon filed a timely notice of appeal. DISCUSSION I. EXPERT TESTIMONY Aguillon argues the trial court prejudicially erred by permitting an expert witness to testify to an ultimate issue in the case. Whether opinion testimony should be admitted is an issue left to the sound discretion of the trial court. (People v . Clark (2019) 43 Cal.App.5th 270, 293.) The prosecutor asked her expert witness on DNA: “So just because DNA is not detected on a victim of a sexual assault, for example, does that mean the sexual assault, did not happen?” Defense counsel objected on the grounds the opinion lacked foundation. The court overruled the objection, and the witness responded, “No.” We disagree with Aguillon’s initial assumption that the expert testified regarding an ultimate issue in the case. The expert did not testify that a sexual assault occurred in this case; rather, she testified that the lack of DNA on the victim did not mean a sexual assault had not occurred. It remained for the jury to determine whether the alleged assaults did or did not occur. Here, the witness testified about how surfaces are tested for DNA evidence and the factors that may affect whether DNA may be found, including washing, bathing, using the bathroom, and whether the surface has been touched multiple times. The expert also testified that some individuals are “shedders,” who deposit large amounts of DNA, while others are “non- shedders,” who deposit little or no DNA. The expert’s challenged testimony
