Background

Jabreon Deshon Mosley appealed his jury-trial convictions and sentence for possessing with intent to distribute at least 500 grams of methamphetamine, at least five kilograms of cocaine, and at least 400 grams of fentanyl.

For the first time on appeal, Mosley alleged that trial counsel was ineffective by admitting that he possessed methamphetamine. He also challenged two sentencing adjustments: a two-level increase for possessing a dangerous weapon in connection with the offense and a four-level increase for knowingly misrepresenting or marketing a fentanyl-containing substance as another substance.

The Court’s Holding

The Fifth Circuit affirmed. It declined to consider Mosley’s ineffective-assistance claim because the record was insufficiently developed for a fair evaluation, leaving him free to raise the claim in collateral review.

The court found no clear error in either sentencing adjustment. The firearms found in Mosley’s residence did not have to be loaded for the dangerous-weapon adjustment to apply, and the government met its burden concerning that enhancement. Significant evidence in the presentence report and record also supported the fentanyl-misrepresentation adjustment, while Mosley offered no rebuttal evidence and did not establish that the relevant findings were unreliable.

Key Takeaways

  • An ineffective-assistance claim first raised on direct appeal may be left for collateral review when the appellate record is not sufficiently developed.
  • A firearm need not be loaded to support the dangerous-weapon adjustment under U.S.S.G. § 2D1.1(b)(1).
  • Unrebutted, reliable evidence in the presentence report and record may support an adjustment for knowingly misrepresenting or marketing a fentanyl-containing substance as another substance.

Why It Matters

The decision reinforces the Fifth Circuit’s usual preference for resolving fact-dependent ineffective-assistance claims through collateral proceedings rather than on an undeveloped direct-appeal record.

It also confirms that unloaded firearms may trigger the drug-offense weapon adjustment and illustrates the importance of presenting rebuttal evidence when disputing factual findings supporting a fentanyl-related sentencing enhancement.
