The Hawaii Intermediate Court of Appeals has upheld the conviction of Justin Joshua Serrano Eugenio for commercial sexual exploitation of a minor. The court's decision, issued on June 19, 2026, confirms the findings of a lower court, which had previously sentenced Eugenio to probation following his conviction in May 2024. This ruling is significant as it reinforces the legal framework surrounding the exploitation of minors in Hawaii and the responsibilities of law enforcement during undercover operations.
The case began when the State of Hawaii charged Eugenio with commercial sexual exploitation of a minor, a serious crime under Hawaii law. The charge stemmed from an undercover operation conducted by the Maui Police Department, where Detective John Surina posed as an underage female prostitute online. The operation aimed to catch individuals attempting to engage in illegal activities with minors. The court's ruling impacts not only Eugenio but also serves as a precedent for future cases involving similar charges and law enforcement practices.
In January 2023, the State filed a Felony Information against Eugenio, accusing him of the crime under Hawaii Revised Statutes § 712-1209.1. The charge was based on evidence gathered during the undercover operation, which included communications between Eugenio and the detective posing as a minor. Following a trial in January 2024, a jury found Eugenio guilty of the charges. He subsequently appealed the conviction, raising several points of error regarding jury instructions and the handling of evidence during the trial.
Eugenio's appeal raised three main arguments. First, he contended that the Circuit Court erred by not providing a jury instruction on the mistake of fact defense. He argued that the police created an impression that the persona was an adult by initially listing her age as 19 and using photos of an adult woman. Second, he claimed that the jury instruction on entrapment was inadequate. Lastly, he argued that the court should have instructed the jury on a specific entrapment defense because of the misleading representations made by law enforcement.
The court ruled against Eugenio on all points. In its opinion, the court stated, "We conclude that there is no credible evidence in the record supporting a mistake of fact defense." The judges noted that Detective Surina had clearly communicated the persona's age as 16 multiple times during their conversations. The court emphasized that Eugenio's responses indicated he was aware of the persona's age, undermining his claim of a mistake of fact.
Regarding the jury instructions, the court found that the instruction on entrapment adequately explained the law. The judges noted that the instruction tracked the statutory language closely and was not misleading. The court stated, "HAWJIC 7.08 adequately and understandably apprised the jury of the law to be applied in its deliberation." This affirmation of the jury instruction reinforces the standards for entrapment defenses in Hawaii.
Additionally, the court dismissed Eugenio's argument concerning the omission of HAWJIC 7.09, which relates to false representations made by law enforcement. The judges concluded that there was no evidence indicating that law enforcement had made false statements that would induce Eugenio to believe his conduct was legal. The ruling clarified that the legality of engaging in sexual conduct with a minor is unequivocal, regardless of the representations made during the operation.
The court's decision has significant implications for future cases involving commercial sexual exploitation and the conduct of undercover operations by law enforcement. It underscores the importance of clear communication regarding the age of individuals involved in such operations and the necessity for defendants to provide credible evidence if they wish to claim a mistake of fact defense. This ruling may also influence how juries interpret entrapment defenses in similar cases, as it establishes a precedent for the adequacy of jury instructions related to these defenses.
Looking ahead, Eugenio may have options for further legal action. However, the court's ruling effectively affirms his conviction, making it more challenging to overturn the decision. The case illustrates the complexities involved in cases of commercial sexual exploitation and the careful balance that must be struck between law enforcement practices and defendants' rights.
In conclusion, the Hawaii Intermediate Court of Appeals has upheld the conviction of Justin Joshua Serrano Eugenio for commercial sexual exploitation of a minor. This ruling reinforces the legal standards regarding the exploitation of minors and the responsibilities of law enforcement in undercover operations. As the legal landscape evolves, this case will likely serve as a reference point for similar cases in the future.
