Summary
This Fifth Circuit per curiam opinion affirms the defendant's convictions for drug conspiracy, distribution, and possession of child pornography stemming from his activities on dark web marketplaces. The court reviews challenges regarding the sufficiency of the evidence for the conspiracy counts, the admissibility of uncharged cryptocurrency transaction testimony and additional child pornography images under Federal Rule of Evidence 404(b), and a sentencing enhancement under the U.S. Sentencing Guidelines. Concluding that the district court did not err, the appellate court affirms the judgment and sentence.

Questions Presented
- Whether the evidence was sufficient to support Shaughnessy’s conspiracy convictions.
- Whether testimony about Shaughnessy’s Bitcoin‑to‑cash transactions with the vendor “Gold” was admissible.
- Whether the district court erred in admitting two uncharged child‑pornography videos under Rule 404(b).
- Whether the sentencing enhancement under U.S.S.G. § 2G2.2(b)(7)(D) was properly applied.
Holdings
- The government presented sufficient circumstantial evidence of a tacit agreement between Shaughnessy and dark‑web marketplace operators and upstream suppliers; a reasonable jury could infer a conspiracy, so the convictions are affirmed.
- The testimony was intrinsic to the drug‑trafficking conspiracy and therefore admissible; the district court did not err.
- The admission was proper because the videos were relevant to Shaughnessy’s knowledge and intent, the probative value outweighed any prejudice, and the limiting instructions mitigated prejudice.
- The district court correctly applied the five‑level enhancement because the evidence established more than 600 images of child pornography; the finding is supported by the preponderance of evidence and is entitled to deference.
Factual background
Shaughnessy operated a multi‑year dark‑web drug‑trafficking enterprise, using pseudonymous vendor accounts on numerous marketplaces, accepting Bitcoin payments, and converting the proceeds to cash via an unregistered vendor. Federal investigations seized narcotics, digital ledgers, and child‑pornography images from his computers and residences.
Procedural history
Shaughnessy was convicted in the Northern District of Texas on two drug‑conspiracy counts, a distribution count, and a child‑pornography possession count. The district court dismissed money‑laundering counts, admitted certain evidence, applied a sentencing enhancement, and sentenced him to 293 months. He appealed the convictions, evidentiary rulings, and sentencing enhancement.
