Procedural Sentencing Challenges Require Timely Objections; Corroborated Hearsay and Uncontested PSR Facts May Support § 2K2.1(b)(6) Enhancements and Major Upward Variances

I. Introduction

In United States v. Lucero (10th Cir. Mar. 11, 2025), Manuel Lucero III—a convicted felon—appealed a 120-month (statutory maximum) sentence imposed after his guilty plea to one count of felon in possession of a firearm and ammunition. The district court varied upward from a Guidelines range of 57–71 months, applied U.S.S.G. § 2K2.1(b)(6) (firearm possessed “in connection with another felony offense”), and denied a day-of-sentencing continuance request.

The appeal presented three core issues: (1) whether the sentence was procedurally unreasonable (inadequate explanation, reliance on “unsourced” PSR facts, and reliance on officer testimony/“layered hearsay” for the enhancement); (2) whether the sentence was substantively unreasonable (overweighting offense conduct/criminal history and creating unwarranted national disparity); and (3) whether denying a continuance was an abuse of discretion.

II. Summary of the Opinion

The Tenth Circuit affirmed in full. It held that Lucero’s procedural challenges were reviewed for plain error because he did not object after the sentence was imposed, and he failed to show any plain error affecting substantial rights. The court also held the upward variance was substantively reasonable under abuse-of-discretion review given the district court’s § 3553(a) analysis, including the violent nature of the offense conduct and Lucero’s criminal history. Finally, the court held the denial of the continuance was not an abuse of discretion because Lucero was not materially prejudiced, particularly where the judge allowed a proffer of the proposed evidence.

Judge McHugh concurred, emphasizing that substantive-reasonableness review should not be a “rubber stamp,” and discussing the role of U.S. Sentencing Commission JSIN data in § 3553(a)(6) disparity analysis. While noting the district court’s treatment of disparity was thin, the concurrence agreed the sentence should be upheld based on other § 3553(a) factors.

III. Analysis

A. Precedents Cited

  • United States v. Romero, 491 F.3d 1173 (10th Cir. 2007): The court used Romero to define plain-error review and to reject an argument that failure to object necessarily constituted waiver (treating it as “inadvertent neglect” rather than intentional abandonment in similar contexts).
  • Gall v. United States, 552 U.S. 38 (2007): Gall supplied the framework for sentencing review—requiring an individualized assessment under § 3553(a), recognizing discretion to vary, and stating that a “major variance” should be supported by a “more significant justification than a minor one.” Both the majority and concurrence relied on Gall to evaluate the justification for the upward variance.
  • United States v. Chavez, 723 F.3d 1226 (10th Cir. 2013): Cited for the requirement that district courts provide an individualized assessment of how § 3553(a) factors apply to the defendant.
  • United States v. Figueroa-Labrada, 720 F.3d 1258 (10th Cir. 2013) and United States v. Malone, 937 F.3d 1325 (10th Cir. 2019): Cited to emphasize that while courts must give reasoning sufficient to support a variance, they need not provide “extraordinary” facts to justify statutorily permissible findings.
  • United States v. Smart, 518 F.3d 800 (10th Cir. 2008): Cited to reinforce that appellate courts must give “due deference” even for large variances, consistent with Gall.
  • United States v. Barnes, 890 F.3d 910 (10th Cir. 2018): Played a central role on two fronts: (1) district courts may consider facts already accounted for in the Guidelines when applying § 3553(a); (2) the adequacy of § 3553(a) consideration/explanation is “the keystone” of substantive review (as stressed in the concurrence).
  • United States v. Hooks, 551 F.3d 1205 (10th Cir. 2009) and United States v. Robertson, 568 F.3d 1203 (10th Cir. 2009): These cases anchored the court’s rejection of “unsourced PSR facts” arguments where the defendant did not specifically object. Uncontested PSR facts are deemed admitted, and Rule 32(i)(3)(A) allows acceptance of undisputed PSR portions.
  • United States v. Ruby, 706 F.3d 1221 (10th Cir. 2013): Provided the standard for sentencing hearsay: admissible if it bears “some minimal indicia of reliability,” with corroboration often key. This controlled the officer-testimony/incident-report dispute for § 2K2.1(b)(6).
  • United States v. Gonzalez-Huerta, 403 F.3d 727 (10th Cir. 2005) and United States v. Dominguez Benitez, 542 U.S. 74 (2004): Used to define the “affects substantial rights” prong of plain error—requiring a reasonable probability of a different outcome.
  • United States v. Trujillo-Terrazas, 405 F.3d 814 (10th Cir. 2005) and United States v. Mendoza, 543 F.3d 1186 (10th Cir. 2008): Cited for the defendant’s burden under plain-error prong three and for how to show prejudice in the sentencing context; Lucero failed by not developing an argument that a lesser sentence was reasonably probable absent the alleged errors.
  • United States v. Sample, 901 F.3d 1196 (10th Cir. 2018) and United States v. Gross, 44 F.4th 1298 (10th Cir. 2022): Sample provided the substantive-reasonableness standard (reasonableness of length given circumstances and § 3553(a)). Gross supported affirming substantial variances when the district court gives valid § 3553(a) reasons; the concurrence also used Gross to illustrate when violent history reasonably supports a variance.
  • United States v. Cordova, 461 F.3d 1184 (10th Cir. 2006) and United States v. Kelley, 359 F.3d 1302 (10th Cir. 2004): Cited to reiterate that district courts need not address each § 3553(a) factor in ritualistic fashion or use “magic words,” so long as the record shows mindful consideration.
  • United States v. McClaflin, 939 F.3d 1113 (10th Cir. 2019): Controlled review of continuance denial, setting out four factors (diligence, likelihood of accomplishing purpose, inconvenience, and need/prejudice) and requiring “material prejudice” for reversal.
  • Concurrence-specific substantive-review guardrails: United States v. Pinson, 542 F.3d 822 (10th Cir. 2008) (substantive review not a “rubber stamp” and affirming major variance tied to violent history/recidivism); United States v. Allen, 488 F.3d 1244 (10th Cir. 2007) (reversal where unreasonable weight placed on unrelated/unadjudicated/dissimilar actions); United States v. Crosby, 119 F.4th 1239 (10th Cir. 2024) (reversal where court almost entirely focused on one factor); United States v. Cookson, 922 F.3d 1079 (10th Cir. 2019) (reversal for nearly exclusive focus; also cited for inadequacy of brief explanation divorced from record); and United States v. Sample again (overriding reliance on one factor can exceed permissible choice).
  • Disparity statistics / JSIN discussion: Majority cited United States v. Willingham, 497 F.3d 541 (5th Cir. 2007) to deem broad averages “basically meaningless” without individual comparability. The concurrence cited United States v. Garcia, 946 F.3d 1191 (10th Cir. 2020) (nationwide disparities are relevant and bare statistics may be insufficiently comparative), and referenced United States v. Brewster, 116 F.4th 1051 (9th Cir. 2024) (JSIN as a reliable sentencing-data source designed to help judges meet § 3553(a)(6)).

B. Legal Reasoning

1. Procedural reasonableness: plain-error framing matters

The panel’s procedural analysis turned on preservation. Because Lucero did not object “on procedural grounds after his sentence was imposed,” the court applied plain-error review. That lens is often outcome-determinative: even arguable mistakes will not yield relief absent a showing of prejudice (a reasonable probability of a different result).

2. Upward variance explanation: individualized § 3553(a) assessment, not “extraordinary facts”

The court rejected the claim that the judge inadequately explained the variance. It found the record reflected an individualized assessment of § 3553(a): seriousness of the conduct (an “egregious case of felon in possession” tied to threats), history/characteristics (criminal history), deterrence and protection of the public (continued violent and weapon-related conduct). The court emphasized that district courts may rely on facts already reflected in the Guidelines calculation when using § 3553(a) to vary upward.

3. “Unsourced” PSR information: failure to object is effectively a factual admission

Lucero’s appellate attack on PSR descriptions of prior violent conduct failed because he did not specifically object to those facts at sentencing. Under Tenth Circuit practice, uncontested PSR facts are deemed admitted, and the government need not produce additional proof. The decision thus underscores a practical rule: defendants must litigate PSR factual disputes in the district court or lose them on appeal.

4. Sentencing hearsay and § 2K2.1(b)(6): corroboration supplies “minimal indicia of reliability”

To support the § 2K2.1(b)(6) enhancement, the government relied on the investigating officer’s testimony and report summarizing statements from the ex-girlfriend and her mother and other investigative details. The panel applied the sentencing-hearsay standard: hearsay is permissible if minimally reliable, and corroboration is “often key.” Here, the district court found consistency between two witness accounts and corroboration in physical recovery of the Beretta at Lucero’s home. The panel found no error—especially because the report was admitted without objection.

5. Plain-error prong three: no developed prejudice argument, no relief

Even assuming an error, the court held Lucero did not carry his burden to show his substantial rights were affected because his brief did not explain why a lower sentence was reasonably probable absent the alleged procedural flaws. The panel declined to build that argument for him, reinforcing that plain-error review is not self-executing.

6. Substantive reasonableness: violent pattern plus recidivism risk justified statutory maximum

On substantive reasonableness, the court deferred to the district court’s weighing of § 3553(a). The judge connected the large variance to multiple statutory purposes: seriousness, deterrence, protection of the public, and Lucero’s history of similar violent behavior. The panel rejected the claim that national-average data (55–57 months) established unwarranted disparity, reasoning that averages do not establish that defendants are actually “similarly situated,” and noting the district court’s view that any disparity would be warranted given Lucero’s conduct and history.

7. Continuance denial: lack of diligence and lack of prejudice

Applying the four-factor test, the court stressed defense counsel’s lack of diligence (request made at sentencing; evidence left “on the back burner”), uncertainty that a continuance would secure the evidence, the inconvenience of delay after a recent continuance, and—most importantly—the lack of material prejudice because the court accepted and considered the proffer “as if it was brought today in court.”

C. Impact

  • Preservation is critical in sentencing appeals. Lucero reinforces that failing to object to procedural issues and PSR facts can shift review to plain error and treat PSR facts as admitted, dramatically reducing appellate prospects.
  • Corroborated hearsay remains a powerful sentencing tool. The opinion confirms that police reports and second-hand witness statements can support enhancements when corroborated and found minimally reliable, even without trial-level confrontation rights.
  • Major upward variances can be sustained when the record ties them to multiple § 3553(a) purposes. The decision illustrates how district courts can justify statutory-maximum sentences in felon-in-possession cases when the firearm possession is embedded in violent, threatening conduct and a pattern of recidivism.
  • National disparity arguments face headwinds unless comparability is developed. The majority treats averages as non-dispositive; the concurrence suggests JSIN data can be relevant to § 3553(a)(6) but emphasizes the need to integrate the statistics with record-specific comparison. Future litigants should expect to brief comparability (offense conduct, aggravators, and history) rather than rely on headline averages.
  • Continuance requests must show diligence and concrete prejudice. Allowing a proffer can substantially undercut claims of harm from denial.

IV. Complex Concepts Simplified

  • Procedural vs. substantive reasonableness: Procedural reasonableness asks whether the court used the right process (correct calculations, consideration of § 3553(a), adequate explanation, proper factfinding). Substantive reasonableness asks whether the length of the sentence is reasonable in light of § 3553(a).
  • Plain error review: A demanding appellate standard applied when a defendant did not preserve an issue. The defendant must show an obvious error and a reasonable probability it changed the outcome.
  • Presentence report (PSR): A probation-prepared report summarizing the offense, background, criminal history, and Guidelines calculations. Unobjected-to facts are generally treated as admitted.
  • Upward variance: A sentence above the advisory Guidelines range, justified by the judge’s assessment of § 3553(a) factors.
  • U.S.S.G. § 2K2.1(b)(6): An enhancement if the firearm/ammunition was used or possessed “in connection with another felony offense,” even if there was no charge or conviction for that other felony.
  • Hearsay at sentencing and “minimal indicia of reliability”: Unlike trials, sentencing can consider hearsay if it appears reliable enough—often shown through corroboration (consistent accounts, physical evidence, contemporaneous reporting).
  • § 3553(a)(6) disparities and JSIN data: Courts consider avoiding unwarranted sentence disparities nationwide among similarly situated defendants. Statistical tools like JSIN may inform that inquiry, but they do not automatically control the outcome without a showing of genuine similarity.

V. Conclusion

United States v. Lucero is a preservation-and-proof decision with practical sentencing consequences. It affirms that (1) procedural sentencing challenges—especially attacks on PSR facts—must be timely raised or are reviewed under strict plain-error standards, often with PSR facts deemed admitted; (2) corroborated hearsay can support sentencing enhancements like § 2K2.1(b)(6); (3) major upward variances, including to the statutory maximum, will be upheld when the district court ties the sentence to an individualized § 3553(a) analysis emphasizing seriousness, deterrence, protection of the public, and recidivism; and (4) continuance denials will stand absent diligence and material prejudice, particularly where the court allows a proffer.
