The First Circuit affirmed Sherriff Cooper’s convictions for sex trafficking of a minor (Count One) and transportation of a minor with intent to engage in illegal sexual activity (Count Two), but vacated his conviction for forced labor (Count Three) and remanded the case for further proceedings. Regarding Count One, the court rejected Cooper’s argument that 18 U.S.C. § 1591(a)(1) is duplicitous because it lists ten alternative acts (“recruits, entices, harbors, transports, provides, obtains, advertises, maintains, patronizes, or solicits”) as separate offenses rather than alternative means of committing a single crime. Applying a de novo standard of review, the court analyzed the statutory text, legislative history, and penalty structure, concluding that Congress intended these acts to be alternative means of the single offense of sex trafficking. Consequently, the indictment provided adequate notice, and no jury unanimity instruction was required regarding which specific act Cooper committed. The court also affirmed the sufficiency of the evidence for Counts One and Two, finding that a rational jury could conclude from J.C.’s testimony and text message records that the crimes affected interstate commerce and that Cooper intended to prostitute the victim during their travel to New York. Regarding Count Three, the court held that the district court committed reversible error by refusing to instruct the jury on venue. While the court agreed with Cooper’s arguments regarding pretrial motions and evidentiary sufficiency for venue were without merit, it applied the framework from *United States v. Perez* to determine that Cooper had properly placed venue “in issue” at trial. By testifying that the forced labor (J.C. working as a stripper) occurred entirely in New York, Cooper created a genuine factual dispute regarding whether the offense began in Massachusetts or New York. Under the majority view of federal courts, when a defendant creates such a factual dispute and timely requests a jury instruction on venue, the issue must be decided by the jury. The court determined this error was not harmless beyond a reasonable doubt because the jury could have convicted Cooper on Count Three based solely on conduct occurring in New York, without ever considering whether the scheme to force labor began in Massachusetts.
