Sixth Circuit: Upward Variance May Rest on Unobjected-to Pretrial Detention Discipline and a District Court May Deem Resulting National Disparity “Warranted”

1. Introduction

United States v. O'Shane Christopher Smith (6th Cir. July 8, 2026) arises from two federal prosecutions stemming from a single arrest: (1) illegal re-entry under 8 U.S.C. § 1326, and (2) drug-trafficking offenses for conspiring to distribute and possessing with intent to distribute methamphetamine under 21 U.S.C. § 841(a)(1), (b)(1)(A). Smith pleaded guilty to all counts and received a combined sentence of 100 months—an upward variance above the advisory Guidelines range of 70–87 months.

The appeal presented two principal substantive-reasonableness challenges under 18 U.S.C. § 3553(a): (i) whether the district court gave excessive weight to pre-sentencing detention disciplinary incident reports, and (ii) whether the court inadequately considered § 3553(a)(6)—the need to avoid unwarranted sentencing disparities. The Sixth Circuit affirmed, holding that the district court acted within its discretion in relying on undisputed PSR facts about detention misconduct and in concluding that any departure from national averages was warranted.

2. Summary of the Opinion

The Sixth Circuit held that Smith’s above-Guidelines sentence was not substantively unreasonable. The district court permissibly treated Smith’s pretrial detention misconduct—including a fight, possession of a homemade weapon, and possession of a razorblade and pills—as relevant to § 3553(a), especially the defendant’s history and characteristics and the need to promote respect for the law.

The court also rejected Smith’s disparity argument. Although the sentencing judge noted an “average” sentence of 45 months for similarly scored offenders, the judge explained why Smith’s circumstances (two convictions sentenced together; repeated illegal entry tied to serious drug activity) justified a longer sentence. The Sixth Circuit emphasized that identifying which disparities are “unwarranted” lies within the district court’s discretion.

3. Analysis

A. Precedents Cited

  • United States v. Robinson, 778 F.3d 515 (6th Cir. 2015): Cited for the general framework that appellate review of sentencing looks to whether the district court properly considered the § 3553(a) factors. In Smith, this supports the panel’s threshold inquiry into the sentencing record rather than a reweighing of facts.
  • United States v. Rayyan, 885 F.3d 436 (6th Cir. 2018): Quoted for the principle that substantive unreasonableness may occur when a court gives too much weight to some factors and too little to others, but also that weighing is “a matter of reasoned discretion, not math.” Smith relies on Rayyan to uphold the district court’s choice to emphasize detention conduct.
  • United States v. Conatser, 514 F.3d 508 (6th Cir. 2008): Provides the key substantive-unreasonableness formulation (arbitrary selection, impermissible factors, failure to consider relevant factors, or unreasonable weight). Conatser also supplies the interpretation that § 3553(a)(6) focuses on national disparities, shaping the panel’s rejection of Smith’s disparity claim.
  • United States v. Bridgewater, 479 F.3d 439 (6th Cir. 2007): Used to reinforce that not every § 3553(a) factor must carry equal weight and that one or two may “prevail.” Smith uses Bridgewater to defend the district court’s emphasis on custodial misconduct.
  • United States v. Axline, 93 F.4th 1002 (6th Cir. 2024) and United States v. Kumar, 750 F.3d 563 (6th Cir. 2014): Cited for abuse-of-discretion review and the “definite and firm conviction” standard for clear error of judgment. These cases set the high bar Smith had to clear to obtain relief on substantive reasonableness.
  • United States v. Robinson, 813 F.3d 251 (6th Cir. 2016): Cited for the proposition that an above-Guidelines sentence is neither presumptively reasonable nor unreasonable—so the panel must evaluate the specific justification.
  • United States v. Perez-Rodriguez, 960 F.3d 748 (6th Cir. 2020) and Gall v. United States, 552 U.S. 38 (2007): Provide the requirement that a significant variance must be supported by a “sufficiently compelling” justification. Smith applies this by examining whether detention misconduct and other facts were an adequate rationale for the upward variance.
  • United States v. Mitchell, 107 F.4th 534 (6th Cir. 2024): A critical authority: “pretrial conduct is an appropriate consideration under § 3553(a)” because it relates to the defendant’s history/characteristics and respect for law. The panel treats Mitchell as directly validating the district court’s reliance on pre-sentencing detention incidents.
  • United States v. Zobel, 696 F.3d 558 (6th Cir. 2012) and United States v. Young, 847 F.3d 328 (6th Cir. 2017): Used to confirm that a sentencing court may emphasize certain factors so long as it adequately considers all relevant information and explains its decision in a way showing the sentence reflects the § 3553(a) factors.
  • United States v. Hymes, 19 F.4th 928 (6th Cir. 2021): Cited for the proposition that deciding “which disparities are unwarranted” is within the district court’s discretion. In Smith, this supports affirmance even though the sentencing judge acknowledged a lower national average.

B. Legal Reasoning

1) Reliance on detention disciplinary incidents as a § 3553(a) basis.
The district court’s upward variance was explicitly tied to Smith’s behavior “while awaiting disposition,” as recorded in the PSR: a physical altercation, possession of a homemade weapon, and possession of a razorblade and pills. The Sixth Circuit treated those incidents as permissible sentencing considerations under § 3553(a)(1) (history and characteristics) and the need to promote respect for the law, consistent with United States v. Mitchell.

The appellate court also highlighted a procedural reality with substantive consequences: Smith did not object to the PSR and did not present alternative facts at sentencing. Under Fed. R. Crim. P. 32(i)(3)(A), the district court could accept undisputed PSR portions as fact. This made the incident descriptions an appropriate factual foundation for the variance, and Smith’s later appellate reframing (razor from a shaving kit; pills prescribed) could not establish an abuse of discretion on the record actually made.

2) The justification for the magnitude of the variance.
Applying Perez-Rodriguez and Gall, the panel evaluated whether the district court gave a “sufficiently compelling” justification for the move above 87 months to 100 months. It found that the sentencing judge’s explanation—emphasizing a “pattern” of noncompliance in custody, weapons/drug possession while detained, and broader criminal conduct (repeat illegal re-entry linked to drug trafficking)—was detailed enough to justify the variance.

3) § 3553(a)(6) and national disparity.
Smith argued that the district court failed to give weight to avoiding unwarranted disparities. The panel disagreed, pointing to the judge’s explicit acknowledgement of an average 45-month sentence for the same offense level and criminal history category, followed by an explanation of why Smith was different. Under Conatser, (a)(6) is about national disparities among similarly situated defendants; under Hymes, judges have discretion to determine which disparities are unwarranted. The Sixth Circuit viewed the district court’s reasoning as a permissible determination that a disparity was warranted given Smith’s circumstances.

C. Impact

Although “not recommended for publication,” the decision reinforces several practical points likely to shape sentencing litigation in the Sixth Circuit:

  • Pre-sentencing detention conduct can independently support upward variances when tied to § 3553(a) purposes (history/characteristics; respect for law), particularly where the conduct involves weapons or contraband.
  • Unobjected-to PSR facts are potent. The opinion underscores that failing to object to PSR incident descriptions may effectively concede the factual predicate for an upward variance.
  • § 3553(a)(6) does not require convergence with “average” sentences. District courts may acknowledge national averages yet impose higher sentences if they explain why the defendant is not similarly situated, and appellate courts will generally defer under abuse-of-discretion review.

4. Complex Concepts Simplified

  • Substantive reasonableness: Whether the length of the sentence is reasonable in light of the statutory sentencing factors, not whether the court followed correct steps (that is procedural reasonableness).
  • Upward variance: A sentence above the advisory Guidelines range based on the judge’s assessment of the § 3553(a) factors (distinct from a “departure,” which is a Guidelines mechanism).
  • § 3553(a)(6) unwarranted disparities: The goal is to avoid unjustified differences in sentences among similarly situated defendants nationwide; some differences are acceptable when justified by real distinctions.
  • Fed. R. Crim. P. 32(i)(3)(A): If the PSR states facts and neither side disputes them, the judge may treat those facts as true for sentencing.
  • Abuse of discretion: A deferential appellate standard; reversal generally requires legal error, clearly erroneous factfinding, or a clear error in judgment.

5. Conclusion

United States v. O'Shane Christopher Smith affirms that a district court may impose a meaningful upward variance based largely on a defendant’s pre-sentencing detention misconduct—especially when the misconduct involves weapons or drugs—and may do so by relying on undisputed PSR facts. The decision also clarifies that § 3553(a)(6) does not compel alignment with national averages where the court reasonably explains why the defendant is not similarly situated and why any resulting disparity is warranted. In combination, these holdings highlight the centrality of making a factual record at sentencing and the breadth of district-court discretion in balancing the § 3553(a) factors.
