Sentencing After Drug-Quantity Verdicts: Higher Weights as “Overlapping Conduct” Under U.S.S.G. § 1B1.3(c) (and Not Necessarily “Acquitted Conduct”)

I. Introduction

In United States v. Tianna Barber (6th Cir. Aug. 14, 2026), Tianna Barber appealed her convictions and sentence arising from a Toledo-area drug conspiracy tied to a Mexican cartel. The government’s proof included surveillance, controlled buys, wiretaps/jail calls, and cooperating-witness testimony. A jury convicted Barber of conspiracy and substantive drug offenses (and one telephone-facilitation count), while finding comparatively low drug-quantity ranges on the verdict form.

Barber’s appeal raised three core issues: (1) whether a federal agent improperly “interpreted” recorded jail calls; (2) whether playing a controlled-buy video violated the Confrontation Clause because a confidential source did not testify; and (3) whether the district court’s Guidelines calculation improperly relied on “acquitted conduct” when it attributed higher drug quantities than the jury’s quantity findings.

II. Summary of the Opinion

The Sixth Circuit affirmed across the board. The court held that: (1) the agent’s testimony largely involved translating drug jargon and coded language and, to the extent some interpretations were “close calls,” any error was not “plain” and did not affect substantial rights; (2) the controlled-buy video did not violate the Confrontation Clause because the confidential source’s statements were admitted for context rather than for their truth (i.e., they were not hearsay); and (3) the district court did not plainly err in using higher drug quantities from the PSR to calculate the Guidelines because U.S.S.G. § 1B1.3(c) permits consideration of “overlapping conduct.”

Judge Thapar concurred in part and in the judgment, agreeing with affirmance but offering a different, “more straightforward” sentencing rationale: the jury did not “acquit” Barber of the higher drug weights because it never unanimously found the higher quantities did not apply under the verdict-form instructions—so the sentencing court did not rely on “acquitted conduct” at all.

III. Analysis

A. Evidentiary Issues

1. Precedents Cited (Agent “Interpretation” Testimony)

  • United States v. Page, 163 F.4th 385 (6th Cir. 2025): supplied the general abuse-of-discretion standard for evidentiary rulings.
  • United States v. Vonner, 516 F.3d 382 (6th Cir. 2008) (en banc): supplied the governing plain-error framework when objections are not properly preserved.
  • United States v. Cox, 871 F.3d 479 (6th Cir. 2017): reinforced that a new appellate theory for excluding evidence triggers plain-error review.
  • United States v. Kilpatrick, 798 F.3d 365 (6th Cir. 2015): recognized the long-standing permissibility of expert law-enforcement testimony translating drug slang and jargon in intercepted communications.
  • United States v. Maya, 966 F.3d 493 (6th Cir. 2020): supported qualification of experienced narcotics investigators to interpret coded language.
  • United States v. Glenn, 146 F.4th 485 (6th Cir. 2025): imposed a key limitation—experts may not “interpret ordinary English language” merely to “tell the jury the government’s theory” where the communications lack specialized jargon.
  • United States v. Warman, 578 F.3d 320 (6th Cir. 2009): supplied the “reasonable possibility” prejudice test for plain-error review of evidentiary admissions.

2. Legal Reasoning (Agent Testimony)

The court treated Barber’s appellate argument—complaining that the agent interpreted “ordinary words and phrases”—as unpreserved because Barber objected at trial only on speculation/foundation grounds. That choice of review standard mattered: under United States v. Vonner, Barber had to show not only error but a clear/obvious one, plus prejudice and a threat to the fairness/integrity of proceedings.

On the merits, the panel emphasized the agent’s extensive narcotics experience and the recurring use of coded language: “brick,” “paint,” “materials,” and an extended “construction job” metaphor. Under United States v. Kilpatrick and United States v. Maya, this was classic expert translation of jargon beyond ordinary juror knowledge.

The opinion acknowledged “closer call” moments (e.g., “half of that,” “what’s his name,” and “them people”), which could resemble the ordinary-language “interpretation” rejected in United States v. Glenn. But because Barber did not object on Glenn’s theory at trial, the record lacked targeted foundation and clarifying testimony; thus any error was not “clear or obvious.” And in any event, the court found no prejudice under United States v. Warman given “ample evidence” independent of the challenged snippets.

3. Precedents Cited (Confrontation Clause / Controlled-Buy Video)

  • Smith v. Arizona, 602 U.S. 779 (2024): reemphasized that the Confrontation Clause principally bars admission of testimonial hearsay; if a statement is not hearsay, the Clause generally is not implicated.
  • United States v. Harrison, 54 F.4th 884 (6th Cir. 2022): approved admission of out-of-court statements when used to provide context for a defendant’s own statements (not for their truth).

4. Legal Reasoning (Confrontation Clause)

Applying Smith v. Arizona, the panel framed the constitutional question as threshold evidentiary: were the confidential source’s statements hearsay offered for their truth? The court answered no. Barber’s statements were admissible as opposing-party statements under Fed. R. Evid. 801(d)(2), and Murphy’s statements were admitted as co-conspirator statements under Fed. R. Evid. 801(d)(2)(E). The remaining source statements were admitted solely for context—e.g., to make Barber’s and Murphy’s responses intelligible—consistent with United States v. Harrison. With “no hearsay,” there was no Confrontation Clause violation.

B. Sentencing: Drug Quantity, “Acquitted Conduct,” and “Overlapping Conduct”

1. Precedents and Authorities Cited

  • Gall v. United States, 552 U.S. 38 (2007): procedural reasonableness includes correct Guidelines calculation.
  • United States v. Vannelli, 171 F.4th 912 (6th Cir. 2026): restated abuse-of-discretion review for procedural reasonableness, subject to plain-error when unpreserved.
  • United States v. Olano, 507 U.S. 725 (1993): distinguished forfeiture from waiver (“intentional relinquishment”).
  • United States v. Boudreau, 564 F.3d 431 (6th Cir. 2009): recognized that the government can forfeit a waiver argument by not timely raising it.
  • U.S.S.G. § 1B1.3(c) and U.S.S.G. § 1B1.3 cmt. n.10: the opinion’s pivotal authority, permitting consideration of conduct that “also establishes, in whole or in part, the instant offense of conviction” (“overlapping conduct”).
  • Evans v. Michigan, 568 U.S. 313 (2013): defined acquittal as a ruling that proof is insufficient to establish criminal liability.
  • United States v. Golobic, 170 F.4th 515 (6th Cir. 2026): treated a “no” answer to a special interrogatory (given unanimity instructions) as not necessarily an acquittal.
  • Alleyne v. United States, 570 U.S. 99 (2013): drug quantity triggering a mandatory minimum is an element of an aggravated offense that must be found by the jury.
  • Jones v. Thomas, 491 U.S. 376 (1989); Blockburger v. United States, 284 U.S. 299 (1932); Brown v. Ohio, 432 U.S. 161 (1977): provided the double-jeopardy framework for greater/lesser-included offenses.
  • Richardson v. United States, 468 U.S. 317 (1984): retrial after a hung jury does not violate Double Jeopardy.
  • Green v. United States, 355 U.S. 184 (1957): discussed “implicit acquittal” when a jury convicts on a lesser charge after full opportunity to convict on the greater.

2. Legal Reasoning (Majority’s Sentencing Holding)

Barber’s appellate theory was that higher PSR quantities amounted to “acquitted conduct” because the jury found lower quantity ranges. But the panel—reviewing for plain error due to Barber’s sentencing concession—held that even assuming Barber’s premise, U.S.S.G. § 1B1.3(c) permitted the district court’s approach. The jury convicted Barber of conspiracy and distribution involving the same drug types; higher quantities of those same drugs “also establish[], in whole or in part,” the offenses of conviction. In the panel’s framing, this makes the conduct “overlapping,” and § 1B1.3(c) does not bar its consideration.

3. Legal Reasoning (Judge Thapar’s Concurrence: Why It Wasn’t “Acquitted Conduct”)

The concurrence would have affirmed on a different ground: the jury did not acquit Barber of higher quantities because it did not unanimously find the higher quantities absent. Relying on United States v. Golobic and the unanimity mechanics of the verdict form instructions (select the minimum if unanimity cannot be reached on a higher amount), Judge Thapar reasoned that the jury’s selection of the lower quantity range could reflect a holdout juror rather than a unanimous rejection of the higher weight. Under Evans v. Michigan, an “acquittal” requires a jury’s conclusive determination (in practice, a unanimous one) that the government failed to prove that conduct; that did not occur.

Addressing Barber’s double-jeopardy argument, the concurrence explained—via Blockburger v. United States and Brown v. Ohio—that retrial on higher weights is barred because conviction of the lesser-included offense precludes successive prosecution for the greater, not necessarily because the jury acquitted on the greater. The concurrence flagged but did not resolve (citing Green v. United States) whether “implicit acquittals” fall within the Guidelines’ “acquitted conduct” definition, noting the parties had not fully briefed the issue and that the verdict-form instructions complicated any implicit-acquittal inference.

C. Impact

  • Expert testimony after Glenn: The decision clarifies that United States v. Glenn does not disable narcotics experts from translating genuinely coded drug jargon; it principally targets “interpretation” of ordinary language where jurors need no specialized help. It also signals that preservation matters: without a Glenn-based objection, close-call testimony is unlikely to be “plain error.”
  • Confrontation Clause and recordings: Following Smith v. Arizona and United States v. Harrison, the opinion reinforces a practical evidentiary pathway for controlled-buy recordings: confidential source statements may be admissible when used only to provide context for the defendant’s statements, reducing Confrontation Clause exposure.
  • Drug-quantity verdict forms and Guidelines litigation: The sentencing analysis strengthens the government’s position where a jury returns lower quantity ranges but the sentencing court attributes higher quantities of the same drugs. The majority’s reliance on U.S.S.G. § 1B1.3(c) frames many such disputes as “overlapping conduct” rather than classic “acquitted conduct.” The concurrence, meanwhile, offers defendants a cautionary lesson: where verdict-form instructions force “minimum quantities” absent unanimity on higher quantities, the resulting lower finding may not amount to an acquittal of higher weights under United States v. Golobic.

IV. Complex Concepts Simplified

  • Plain error (Fed. R. Crim. P. 52(b)): If a party did not properly object, appellate reversal requires an obvious legal mistake that likely changed the outcome and undermined the proceeding’s fairness.
  • Expert “translation” vs. improper “interpretation” (Fed. R. Evid. 702): Experts may decode jargon (“brick,” “paint”) but generally may not tell the jury what ordinary phrases mean when jurors can understand them unaided.
  • Hearsay vs. context: A statement is hearsay only if offered for its truth. When admitted merely to make another speaker’s responses understandable, it can be non-hearsay “context.”
  • Confrontation Clause: It primarily restricts admission of out-of-court testimonial statements offered as evidence for their truth. Non-hearsay context statements typically do not trigger the Clause.
  • “Acquitted conduct” vs. “overlapping conduct” (U.S.S.G. § 1B1.3(c)): Even if a defendant is not convicted of an aggravated variant (e.g., higher quantity), the same underlying conduct may still be used at sentencing if it also proves (in whole or part) the convicted offense.
  • Unanimity mechanics in special verdicts: If jurors must select the lowest option when they cannot unanimously agree on a higher one, the “lower” selection may not reflect a unanimous rejection of the higher fact—potentially affecting whether the higher fact was truly “acquitted.”

V. Conclusion

United States v. Tianna Barber is significant for two recurring criminal-law pressure points: the boundary between legitimate expert decoding of drug code and improper interpretation of ordinary language, and the admissibility of controlled-buy recordings without live confidential-source testimony. Most notably, it fortifies the Sixth Circuit’s approach to post-verdict drug-quantity disputes by emphasizing that higher quantities of the same drugs may be treated as permissible “overlapping conduct” under U.S.S.G. § 1B1.3(c), while the concurrence underscores that a lower quantity finding produced by non-unanimity instructions may not constitute an “acquittal” of higher quantities in the first place.
