Upward Variance to Statutory Maximum Upheld Based on Persistent Reoffending and Post-Release Misconduct: United States v. Shiheem Amos

1. Introduction

In United States v. Shiheem Amos (3d Cir. Jan. 21, 2026) (not precedential), the Third Circuit affirmed a 120-month sentence (the statutory maximum) imposed on resentencing for a felon-in-possession conviction. The key dispute was substantive reasonableness: whether the District Court abused its discretion by varying upward from the recalculated Guidelines range (30–37 months) to the statutory maximum, heavily emphasizing Amos’s lengthy criminal history and post-release conduct, while allegedly undervaluing the need to avoid unwarranted sentencing disparities.

The case arose after an earlier Third Circuit decision vacated Amos’s prior 62-month sentence because a Pennsylvania second-degree aggravated assault conviction was deemed not to qualify as a “crime of violence” for a Guidelines enhancement. By the time of resentencing, Amos had completed his prison term, but his conduct after release—including new criminal conduct, failure to pursue mental-health treatment, and absconding—became central to the District Court’s § 3553(a) analysis.

2. Summary of the Opinion

The Third Circuit affirmed. It held the sentence substantively reasonable under the deferential abuse-of-discretion standard, concluding the District Court acted within its discretion in giving significant weight to Amos’s extensive criminal history and demonstrated resistance to deterrence, and in concluding that no meaningful comparator existed for disparity purposes. The panel emphasized that appellate courts do not reweigh § 3553(a) factors and will not vacate a sentence simply because another sentencing court might have imposed a lower one.

Notably, the panel also explained (in background discussion) that intervening Supreme Court authority—Delligatti v. United States—undermined prior Third Circuit omission-based reasoning relevant to “use of force” questions, meaning the “law of the case” doctrine would not lock in the earlier approach. However, because the District Court did not apply the “crime of violence” base offense level at resentencing, the panel expressly declined to decide whether Amos’s Pennsylvania aggravated assault conviction qualifies as a crime of violence under U.S.S.G. § 2K2.1(a)(4)(A).

3. Analysis

3.1. Precedents Cited

  • United States v. Amos, 88 F.4th 446 (3d Cir. 2023)
    The prior appeal vacated Amos’s original sentence because the District Court had treated his Pennsylvania aggravated assault as a “crime of violence” supporting a higher base offense level. In the 2026 opinion, that history sets the procedural stage: resentencing occurred because the initial Guidelines calculation was erroneous under then-controlling circuit law.
  • United States v. Jenkins, 68 F.4th 148 (3d Cir. 2023)
    Jenkins held that “second-degree aggravated assault in violation of 18 Pa. Cons. Stat. § 2702(a)(3) can be committed by a failure to act, so it is not a ‘violent felony.’” The 2026 panel notes that the earlier Amos vacatur relied on this omission-based reasoning. But the opinion treats Jenkins primarily as a now-diminished foundation in light of intervening Supreme Court authority.
  • Delligatti v. United States, 604 U.S. 423 (2025)
    This is the opinion’s most consequential “new law” reference. The Supreme Court clarified that knowing or intentional causation of injury or death—“whether by act or omission”—“necessarily involves the use of physical force against another person.” The Third Circuit invokes Delligatti to explain why omission-based “use of force” analyses (such as those relied upon in Jenkins) no longer necessarily control, and why “law of the case” constraints from the earlier appeal do not dictate the outcome after remand.
  • In re Pharmacy Benefit Managers Antitrust Litig., 582 F.3d 432 (3d Cir. 2009)
    Cited for the “law of the case” principle and its limits. The panel uses it to support the proposition that intervening controlling authority can permit a court to depart from earlier panel reasoning within the same litigation trajectory.
  • In re Krebs, 527 F.3d 82 (3d Cir. 2008)
    Reinforces the exception: a later panel may reevaluate a prior panel’s holding when intervening Supreme Court precedent conflicts. This is used to justify why omission-based “use of force” doctrine from earlier circuit decisions would not necessarily bind the court after Delligatti.
  • United States v. Seibert, 971 F.3d 396 (3d Cir. 2020), opinion clarified, 991 F.3d 1313 (3d Cir. 2021)
    The key Third Circuit authority for deference in substantive-reasonableness review: appellate courts defer to district courts’ weighing of § 3553(a) factors, including credibility and fact-bound judgments, and a defendant’s disagreement with weighting does not make a sentence unreasonable.
  • United States v. Tomko, 562 F.3d 558 (3d Cir. 2009) (en banc)
    Provides the core articulation of the deferential standard and reinforces that district courts are best positioned to weigh sentencing facts. The 2026 opinion quotes Tomko both directly and via Seibert in framing the “no reasonable sentencing court” threshold.
  • Concepcion v. United States, 597 U.S. 481 (2022) (quoting Solem v. Helm, 463 U.S. 277 (1983))
    Used to emphasize role separation: appellate courts do not substitute their judgment for the sentencing court’s assessment of an appropriate sentence. This supports affirmance even if the appellate panel might have chosen a different sentence.
  • United States v. Douglas, 885 F.3d 145 (3d Cir. 2018)
    Supplies the substantive reasonableness framing—reviewing the “totality of the circumstances”—and is used to support the ultimate conclusion that the 120-month variance was within discretion.
  • United States v. Bungar, 478 F.3d 540 (3d Cir. 2007)
    Central to the court’s treatment of repeated criminal conduct as a legitimate basis for above-Guidelines sentencing. Bungar supports the idea that “return to illegal conduct” and an “extensive history of violent criminal offenses” can justify an upward variance.
  • United States v. Johnson, 803 F.3d 610 (11th Cir. 2015) and United States v. Nelson, 793 F.3d 202 (1st Cir. 2015)
    Cited as persuasive authority reinforcing appellate deference to district courts’ weighing of § 3553(a) factors and affirming upward variances when the sentencing judge provides a deliberative rationale.

3.2. Legal Reasoning

The court’s reasoning is structured around substantive reasonableness and deference:

  1. Guidelines were correctly calculated and undisputed. At resentencing, the District Court calculated a total offense level of 12 and criminal history category VI, yielding a range of 30–37 months, and no party objected. That correct baseline reduced the appeal to whether the upward variance to 120 months was nonetheless reasonable under § 3553(a).
  2. District courts may weigh criminal history heavily—especially when it shows deterrence failure. The panel emphasized Amos’s decades-long pattern of serious offenses and, crucially, his post-release conduct (new criminal acts, noncompliance with treatment, absconding). Those facts were treated as strong evidence that previous punishment and supervision had not deterred him, and that incapacitation and public protection were weighty considerations.
  3. Relevant conduct and background facts can be considered even absent a Guidelines enhancement. Although the District Court did not apply a crime-of-violence enhancement, it still treated the violent conduct underlying the prior aggravated assault as a permissible part of Amos’s “background” in the § 3553(a) analysis. The panel approved that approach as consistent with broad sentencing discretion.
  4. Disparity analysis requires “unwarranted” disparity, and comparators must be comparable. The District Court acknowledged § 3553(a)(6) and found no comparable defendants. On appeal, Amos urged comparison to supervised-release violators facing 24-month caps; the panel rejected that as inapt because he was being resentenced for the original felon-in-possession conviction, not sentenced for a supervised-release violation.
  5. Appellate review does not reweigh factors. The panel relied on Tomko, Seibert, and Concepcion to underscore that disagreement with factor-weighting is insufficient; the question is whether “no reasonable sentencing court” would impose the same sentence for the reasons given.

3.3. Impact

Although designated “NOT PRECEDENTIAL,” the opinion has practical significance in three ways:

  • Resentencing can incorporate intervening conduct as powerful § 3553(a) evidence. The case illustrates that post-release misconduct occurring while an appeal is pending can materially shape the resentencing outcome, particularly on deterrence and public-protection rationales.
  • Large upward variances remain defensible with a well-developed record. Even a jump from 30–37 months to 120 months can survive review when the sentencing court documents persistent recidivism, supervision failures, and the inadequacy of lesser sanctions, and ties those facts explicitly to § 3553(a).
  • Delligatti casts a long shadow over omission-based “use of force” analyses. While the panel avoided deciding the crime-of-violence question under § 2K2.1(a)(4)(A), its discussion signals that earlier Third Circuit reasoning that treated omission-capable offenses as nonviolent (as in United States v. Jenkins) may be unstable after Delligatti. Future litigants can expect renewed disputes about how far Delligatti reaches across Guidelines and ACCA contexts.

4. Complex Concepts Simplified

Substantive reasonableness
An appellate check on whether the length of the sentence makes sense given the statutory factors. It is highly deferential: the sentence is affirmed unless it is outside the range of choices a reasonable judge could make.
18 U.S.C. § 3553(a) factors
The required sentencing considerations, including seriousness of the offense, deterrence, protection of the public, the defendant’s history and characteristics, and avoidance of unwarranted disparities.
Guidelines range vs. variance
The Sentencing Guidelines provide an advisory range. A “variance” is a judge’s decision to impose a sentence above or below that range based on § 3553(a).
Statutory maximum
The maximum prison term permitted by Congress for the offense. Here, the District Court varied upward to the 120-month cap.
Law of the case (and the intervening-authority exception)
Generally, courts stick with earlier rulings in the same case. But if a higher court issues an intervening decision that changes the controlling law (here, Delligatti), prior reasoning need not control.
“Crime of violence” enhancements (background concept)
Certain prior convictions can increase the Guidelines calculation if they qualify as “crimes of violence.” Although central to the earlier appeal, the 2026 panel did not decide that issue because the enhancement was not applied at resentencing.
Resentencing vs. supervised-release revocation
Resentencing revisits punishment for the original crime (and can reach the statutory maximum for that offense). Revocation punishes violations of supervised release and is typically subject to separate statutory caps (often 24 months depending on the underlying offense class).

5. Conclusion

United States v. Shiheem Amos affirms a core sentencing principle: when a district court thoroughly grounds its decision in § 3553(a)—especially deterrence, public protection, and a defendant’s demonstrated recidivism—an upward variance to the statutory maximum can be substantively reasonable even where the advisory Guidelines range is far lower. The opinion also highlights the doctrinal significance of intervening Supreme Court authority (Delligatti) in loosening the grip of prior omission-based “use of force” reasoning and limiting “law of the case” constraints in resentencing proceedings.
