The Ninth Circuit affirmed Daekun Cho's convictions for extortion and carjacking, ruling that any evidentiary errors at trial were harmless given the overwhelming proof of guilt. The court also upheld the sentencing enhancement for victim vulnerability, finding that Cho targeted victims based on their immigration status and language barriers.

Daekun Cho was convicted in the Central District of California of extortion and attempted extortion under 18 U.S.C. § 1951(a), as well as aiding and abetting carjacking under 18 U.S.C. §§ 2(a) and 2119(2). The government presented evidence that Cho threatened and attacked victims who failed to pay him, including a specific incident where Cho and an accomplice beat a victim named Yun Soo Shin. Cho appealed his convictions and a sentencing enhancement under U.S.S.G. § 3A1.1(b), arguing that the district court improperly admitted evidence of an uncharged shooting and gang affiliation, and that the court erred in excluding certain group chat messages that he claimed were exculpatory. He also challenged the finding that his victims were unusually vulnerable.

The panel addressed three primary issues. First, regarding the admission of uncharged shooting and gang affiliation evidence, the court assumed for argument's sake that the district court erred but applied the non-constitutional harmless error standard. The court found that multiple victims testified they paid Cho out of fear and that Cho participated in the carjacking. Cho argued the victim testimony was unreliable due to government offers of immigration assistance and inconsistencies in the victim's statements. The court rejected these arguments, noting Cho failed to show the testimony was tainted by immigration assistance and had forfeited arguments regarding the victim's identification of Cho's voice. Furthermore, the court found that the inconsistency in the victim's initial police report was plausibly explained by the administration of strong pain medication, and corroborating testimony from the victim's business partner confirmed the attack. Second, the court addressed the exclusion of group chat messages. While the court acknowledged the district court may have abused its discretion by excluding the messages as hearsay, it found the error harmless because the jury was already aware of the communications and the excluded statements were cumulative of other evidence. Third, the court upheld the sentencing enhancement for victim vulnerability. The court found the district court reasonably determined that the victims' immigration status, language barriers, and lack of familiarity with the legal system made them particularly susceptible to extortion, a factor not already accounted for in the base offense guidelines.

Cho's convictions and sentencing enhancements remain in effect. The decision reinforces the Ninth Circuit's application of the non-constitutional harmless error standard, requiring a showing that an error more probably than not affected the verdict to warrant reversal. It also clarifies that sentencing enhancements for victim vulnerability can be sustained when the record supports a finding that the defendant targeted individuals based on specific vulnerabilities like immigration status, even if those factors are not explicitly incorporated in the offense guidelines.
