Accomplice Liability Does Not Defeat “Crime of Violence” Status for Pennsylvania § 2702(a)(4) Under the Career-Offender Elements Clause

Introduction

In United States v. Brock Cochran (3d Cir. Apr. 14, 2026) (nonprecedential), Brock Cochran appealed a federal sentence imposed by the U.S. District Court for the Western District of Pennsylvania after he pled guilty to two federal drug-trafficking offenses: attempted possession with intent to distribute 500 grams or more of cocaine, and possession with intent to distribute fentanyl. The dispute on appeal concerned sentencing—specifically, whether Cochran was properly classified as a career offender under U.S.S.G. § 4B1.1.

The career-offender designation depended in part on whether a prior Pennsylvania conviction—aggravated assault with a deadly weapon under 18 Pa. C.S. § 2702(a)(4)—counted as a “crime of violence” under U.S.S.G. § 4B1.2(a). Cochran’s specific argument was narrow but important: even if § 2702(a)(4) is ordinarily a “crime of violence,” it should not qualify when his conviction was predicated on accomplice liability rather than principal liability.

Summary of the Opinion

The Third Circuit affirmed the sentence. Relying on its earlier holding that § 2702(a)(4) “categorically has ‘physical force’ as an element,” the court concluded that accomplice liability does not change the elements analysis: when the substantive offense includes the use/attempted use/ threatened use of physical force as an element, that same force element remains present even if the defendant is convicted as an accomplice.

The court also endorsed an alternative rationale used by the District Court: under Gonzales v. Duenas-Alvarez, aiding-and-abetting liability generally tracks the substantive offense unless the defendant demonstrates that the jurisdiction’s accomplice doctrine is “special” in a way that sweeps more broadly than the generic definition. Cochran made no such showing regarding Pennsylvania law.

Analysis

Precedents Cited

1) Framework for “crime of violence” determinations

  • United States v. Brown, 765 F.3d 185 (3d Cir. 2014): cited for the standard of review—plenary review applies to whether a prior conviction is a “crime of violence” for career-offender purposes.
  • United States v. Ramos, 892 F.3d 599 (3d Cir. 2018): the central precedent. Ramos held (i) Pennsylvania’s aggravated assault statute, 18 Pa. C.S. § 2702, is divisible (supporting the modified categorical approach) and (ii) § 2702(a)(4) qualifies under the elements clause because it categorically requires “physical force” as an element. Cochran does not (and effectively cannot, in this panel posture) relitigate Ramos’s core holding about § 2702(a)(4) itself; instead, he tries to distinguish accomplice-based convictions.
  • United States v. Wilson, 880 F.3d 80 (3d Cir. 2018): cited (via Ramos) for the categorical-approach comparison—elements of the statute of conviction versus the Guidelines definition.
  • Descamps v. United States, 570 U.S. 254 (2013): supplies the definition of a divisible statute and the justification for the modified categorical approach when a statute lists alternative crimes.

2) Accomplice liability and the “force element”

  • United States v. Stevens, 70 F.4th 653 (3d Cir. 2023): the opinion’s key analogical bridge. Stevens held that a conviction for Hobbs Act robbery premised on accomplice liability qualifies as a “crime of violence” under the elements clause of 18 U.S.C. § 924(c). The Stevens logic: under aiding-and-abetting principles, if the substantive offense has a force element, the aiding-and-abetting version necessarily incorporates that same element.
  • United States v. Petersen, 622 F.3d 196 (3d Cir. 2010): quoted in Stevens for the federal aiding-and-abetting elements (knowledge of the offense and intent to facilitate it), reinforcing that aiding-and-abetting liability is a theory of committing the substantive offense, not a distinct “lesser” offense lacking the substantive elements.
  • Commonwealth v. Brown, 375 A.2d 331 (Pa. 1977): used to support the Pennsylvania-law proposition that accomplice liability requires proof that “the commission of the crime” occurred—i.e., the offense’s commission remains an element of the accomplice’s liability.
  • Commonwealth v. Roebuck, 32 A.3d 613 (Pa. 2011): cited for two points: (i) accomplice culpability derives from the mental state required for the principal offense, and (ii) conspiracy and accomplice liability are distinct doctrines under Pennsylvania law.

3) Mens rea limits and inapposite conspiracy precedent

  • United States v. Quinnones, 16 F.4th 414 (3d Cir. 2021): cited for the proposition that an offense requiring mere recklessness is not a “crime of violence.” The panel uses Quinnones chiefly to reject Cochran’s attempt to reframe accomplice liability as “less culpable” in a way that might undermine the elements-clause analysis.
  • United States v. Abreu, 32 F.4th 271 (3d Cir. 2022): held that conspiracy is not a “crime of violence” under the Guidelines. The panel explains Abreu is irrelevant because Cochran’s conviction is for aggravated assault (via accomplice liability), not conspiracy.

4) Alternative “generic accomplice liability” route

  • Gonzales v. Duenas-Alvarez, 549 U.S. 183 (2007): establishes that aiding-and-abetting generally counts toward the generic offense unless the defendant shows the jurisdiction’s accomplice doctrine is “special” (overbroad compared to the generic definition).
  • United States v. Carr, 107 F.4th 636 (7th Cir. 2024) and United States v. Yackel, 990 F.3d 1132 (8th Cir. 2021): cited as examples of other circuits applying Duenas-Alvarez to Guidelines “crime of violence” questions involving accomplice liability.

Legal Reasoning

  1. Start with the elements clause and the modified categorical approach. The panel reiterates the elements-clause inquiry under U.S.S.G. § 4B1.2(a)(1) and confirms that 18 Pa. C.S. § 2702 is divisible, so courts may identify which subsection—here, § 2702(a)(4)—formed the basis of conviction. Under United States v. Ramos, § 2702(a)(4) categorically includes “physical force” as an element.
  2. Accomplice liability does not remove elements of the substantive offense. The court’s core move is to treat “accomplice liability” as a theory of liability for the same substantive offense, not a separate offense with a different element set. Drawing from United States v. Stevens, it reasons: if the underlying offense requires force, then liability for aiding/abetting (or its Pennsylvania analogue) necessarily involves that same force element, regardless of whether the accomplice personally applied force.
  3. Pennsylvania accomplice law is materially similar to the federal aiding-and-abetting framework. Citing 18 Pa. C.S. § 306(c) and § 306(g), plus Commonwealth v. Brown, the panel emphasizes that Pennsylvania requires proof of the offense’s commission and the defendant’s complicity. The “commission of the offense” entails the offense’s elements—so the force element is not “lost” when conviction is based on complicity.
  4. The court rejects efforts to smuggle in a “recklessness” problem. Cochran relied on the idea (recognized in United States v. Quinnones) that reckless offenses are not crimes of violence. The panel responds that § 2702(a)(4) requires intentional or knowing conduct, and, via 18 Pa. C.S. § 306(d) and Commonwealth v. Roebuck, an accomplice must meet the culpability required for the substantive offense.
  5. Conspiracy precedent does not apply. Cochran’s attempt to analogize accomplice liability to conspiracy fails because Pennsylvania law differentiates them (citing Commonwealth v. Roebuck). Therefore United States v. Abreu (conspiracy not a crime of violence) does not undermine treating accomplice-based aggravated assault as a crime of violence.
  6. Alternative rationale: Duenas-Alvarez “special” jurisdiction test. Even if one did not adopt the Stevens-style “elements carry over” framing, the panel agrees with the District Court that Gonzales v. Duenas-Alvarez forecloses Cochran’s argument absent proof that Pennsylvania accomplice liability is unusually broad. Cochran did not attempt that showing.

The opinion also notes (but does not depend on) the 2023 amendment adding U.S.S.G. § 4B1.2(d) clarifying that “crime of violence” includes “aiding and abetting.” The panel treats the case as resolvable without the amendment because, on its analysis, § 2702(a)(4) qualifies under the elements clause even under earlier Guidelines versions.

Impact

Although labeled “NONPRECEDENTIAL,” the decision is practically significant in three ways:

  • Career-offender litigation in the Third Circuit: It signals that defendants cannot avoid Ramos by recharacterizing qualifying violent predicates as accomplice-based convictions. For Pennsylvania aggravated assault under § 2702(a)(4), the force element remains dispositive under the elements clause.
  • Broader “theory of liability” disputes: The opinion reinforces a general approach: where state accomplice liability requires commission of the substantive offense plus intentional facilitation, accomplice liability typically does not change the categorical-elements analysis. That can influence future disputes involving other Pennsylvania violent predicates (and similar state complicity statutes).
  • Doctrinal convergence with other circuits: By endorsing Duenas-Alvarez and citing United States v. Carr and United States v. Yackel, the panel aligns Third Circuit reasoning with a cross-circuit trend: absent proof of an unusually broad accomplice doctrine, aiding-and-abetting convictions are treated as equivalent to principal offenses for predicate-offense purposes.

Complex Concepts Simplified

Career offender (U.S.S.G. § 4B1.1)
A Guidelines enhancement that increases a defendant’s sentencing range if the defendant has specified qualifying prior convictions (typically two) and the current offense is a qualifying felony.
Crime of violence — “elements clause” (U.S.S.G. § 4B1.2(a)(1))
A prior offense qualifies if its legal elements require “the use, attempted use, or threatened use of physical force” against another person. The focus is on what the statute requires for conviction, not the facts of what happened in a particular case.
Categorical approach / modified categorical approach
The categorical approach compares a statute’s elements to the Guidelines definition. If the statute lists multiple alternative crimes (a “divisible” statute), the modified categorical approach allows courts to identify which alternative formed the conviction and then apply the categorical comparison to that specific alternative.
Divisible statute
A statute that sets out multiple, alternative versions of an offense (as described in Descamps v. United States). Pennsylvania’s aggravated assault statute is divisible (per United States v. Ramos).
Accomplice liability vs. conspiracy
Accomplice liability is a way of being held liable for the substantive crime because you intentionally aided or facilitated it. Conspiracy is a separate agreement-based offense. Pennsylvania law treats these as distinct (as emphasized via Commonwealth v. Roebuck).
Duenas-Alvarez “special” accomplice doctrine
Under Gonzales v. Duenas-Alvarez, aiding-and-abetting is generally treated as included within the generic offense unless the defendant shows the jurisdiction’s accomplice doctrine is unusually broad—covering conduct outside the generic definition.

Conclusion

The Third Circuit affirmed Cochran’s career-offender designation by articulating a clear rule for this context: when 18 Pa. C.S. § 2702(a)(4) qualifies as a “crime of violence” under the Guidelines’ elements clause, that conclusion does not change merely because the conviction was obtained on an accomplice-liability theory. Relying on United States v. Ramos and the analytic framework of United States v. Stevens, the court treated accomplice liability as inheriting the substantive offense’s force element. As a backstop, the court also agreed that Gonzales v. Duenas-Alvarez defeats the claim absent proof that Pennsylvania’s accomplice liability doctrine is “special” in an overbroad way—proof Cochran did not offer.
