United States v. Malave: Broad Digital-Warrant Searches, “Teaching Expert” Testimony, and Substantial-Step Attempt Liability in RICO/Sex-Trafficking Prosecutions

Court: U.S. Court of Appeals for the Third Circuit
Date: September 15, 2026
Disposition: Affirmed (nonprecedential)

I. Introduction

This consolidated appeal arose from a wide-ranging federal prosecution targeting a violent criminal ecosystem centered on a “boarding house” in Reading, Pennsylvania. The government alleged that the boarding house functioned as a hub for drug distribution, prostitution, and violence and that two defendants (Shaquile Newson and Alexander Malave) founded a gang known as “The Sevens,” which imposed control over residents, drug sellers, and sex-trafficking activity.

After a jury trial, defendants James Goode, Karvarise Person, Alexander Malave, and Shaquile Newson were convicted of various offenses including RICO conspiracy, sex trafficking and sex-trafficking conspiracy, assaults, and firearm offenses. They received severe sentences (including life-plus terms for Malave and Person).

On appeal, the defendants pressed challenges spanning (i) severance, (ii) evidentiary rulings (including expert testimony), (iii) sentencing guideline calculations and relevant conduct, (iv) Fourth Amendment suppression issues tied to a digital-device search, (v) a constitutional vagueness challenge to 18 U.S.C. § 1591(c), and (vi) sufficiency of the evidence. The Third Circuit rejected all claims and affirmed.

Although designated “NONPRECEDENTIAL” under 3d Cir. IOP 5.7, the opinion is a useful synthesis of recurring issues in complex conspiracy trials: joinder/severance, “teaching expert” admissibility under Rule 702, breadth of digital search warrants and good-faith reliance, relevant-conduct attribution for leaders in conspiracies, and attempt-liability framing under the “substantial step” test.

II. Summary of the Opinion

  • Appellate jurisdiction despite untimely notice: The court exercised jurisdiction over Newson’s late notice of appeal because the government did not object, citing Manrique v. United States.
  • Severance denied: No abuse of discretion in trying Goode jointly with more violent co-defendants; limiting instructions and lack of mutually antagonistic defenses defeated the claim.
  • Evidence admitted (guns/drugs): Contraband seized from Goode’s home was relevant to proving his participation in the charged conspiracy.
  • Guidelines challenges (Goode): No clear error in drug quantity estimate or enhancements (violence; drug-premises), and any hypothetical error would be harmless because the guideline range would not change.
  • Rule 702 “fit” satisfied: Expert testimony on gang dynamics and sex-trafficking methods properly assisted the jury as “teaching experts.”
  • 18 U.S.C. § 1591(c) vagueness not reached: The jury found Person knew or recklessly disregarded the minor’s age, making any vagueness argument irrelevant to the conviction.
  • Digital search warrants upheld (Malave): The 2018 state warrant had a sufficient nexus and justified a broad extraction; alternatively, good faith applied. Evidence found “in plain view” supported a later 2022 federal warrant.
  • Authentication of jail messages: Under Rule 901(a), the government made the “slight” prima facie showing required; no plain error.
  • Relevant conduct (Malave): The district court did not clearly err in attributing co-conspirator conduct to Malave, given his leadership role and the Collado scope/furtherance/foreseeability framework; in any event, any error was harmless because the offense level still produced life.
  • Sufficiency of evidence: All challenges failed under the deferential standard; the court reaffirmed its “substantial step” approach to attempt (rejecting the Fourth Circuit’s probability-focused language in United States v. Engle).

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. Appellate timing and discretionary hearing of late appeals

  • Manrique v. United States, 581 U.S. 116 (2017): The panel relied on Manrique for the proposition that a Rule 4(b) defect is not jurisdictional in the strict sense and that an appellate court may proceed when the government does not object. The court used this to avoid penalizing Newson for counsel’s failure to file a timely notice despite a timely fee payment.

2. Severance, joint trials, and compartmentalization in multi-defendant conspiracies

  • United States v. Heatherly, 985 F.3d 254 (3d Cir. 2021): Supplied the abuse-of-discretion standard for severance denials.
  • Zafiro v. United States, 506 U.S. 534 (1993): Framed the tension between prejudice risk in joint trials and the preference for joint trials; also clarified that “mutually antagonistic defenses are not prejudicial per se.”
  • United States v. Urban, 404 F.3d 754 (3d Cir. 2005) (quoting Zafiro): Reinforced the “fundamental principle” favoring joint trials for efficiency and consistent verdicts.
  • United States v. Voigt, 89 F.3d 1050 (3d Cir. 1996): Heightened preference for joint trials in conspiracy cases because they help the factfinder see the conspiracy’s full scope and prevent tactical disadvantage from forced disclosure.
  • United States v. Savage, 85 F.4th 102 (3d Cir. 2023): Provided the “heavy burden” language imposed on appellants seeking severance.
  • United States v. Sandini, 888 F.2d 300 (3d Cir. 1989): Addressed the logic supporting severance where defenses are irreconcilable and mutually exclusive; here, the absence of such defenses undercut Goode’s argument.

Together, these authorities structured the court’s severance analysis: despite graphic evidence of violence attributable more strongly to some defendants than others, limiting instructions and the lack of mutually exclusive defenses kept the trial within permissible joint-trial boundaries.

3. Evidence admissibility and discretion

  • Affiliated Mfrs., Inc. v. Aluminum Co., 56 F.3d 521 (3d Cir. 1995): Provided the abuse-of-discretion standard for evidentiary decisions, supporting affirmance of admitting Goode’s guns and drugs as probative of his conspiracy participation.

4. Guidelines review, enhancements, and harmless error

  • United States v. Grier, 475 F.3d 556 (3d Cir. 2007) (en banc): Supplied the review framework—de novo for guideline interpretation, clear error for sentencing facts.
  • United States v. Rodriguez, 40 F.4th 117 (3d Cir. 2022): Influenced the application of the U.S.S.G. § 2D1.1(b)(12) drug-premises enhancement by recognizing “supervising” or “protecting” a distribution site can suffice even without ownership.
  • United States v. Isaac, 655 F.3d 148 (3d Cir. 2011): Anchored the harmless-error conclusion where the guideline range would remain unchanged (Goode), and later where Malave’s offense level would still exceed the de facto maximum (43) yielding life.

5. Rule 702 experts: qualification, reliability, and “fit”

  • United States v. Schiff, 602 F.3d 152 (3d Cir. 2010) (quoting Pineda v. Ford Motor Co., 520 F.3d 237 (3d Cir. 2008)): Supplied the three-part Rule 702 formulation—qualification, reliability, and fit.
  • Heller v. Shaw Indus., Inc., 167 F.3d 146 (3d Cir. 1999): Standard of review (abuse of discretion) for Rule 702 rulings.
  • United States v. Perez, 280 F.3d 318 (3d Cir. 2002): Validated “teaching expert” testimony explaining criminal methods unfamiliar to jurors (there, gangs’ use of communication devices; here, gang cohesion and sex-trafficking control tactics).

The court used these precedents to reject the defendants’ “fit” objections. It emphasized that general expert context can assist the jury on legally salient elements (e.g., RICO “enterprise”; sex-trafficking “force, fraud, or coercion”) even absent case-specific opinions.

6. Fourth Amendment: particularity, nexus, digital searches, good faith, and plain view

  • United States v. Ritter, 416 F.3d 256 (3d Cir. 2005): Provided the dual requirements for warrants—particularity and probable cause/nexus—and the appellate review approach (plenary for legal determinations; deference to the issuing magistrate’s probable-cause finding).
  • United States v. Stabile, 633 F.3d 219 (3d Cir. 2011): A key digital-search precedent supporting broad imaging/extraction where it is not knowable in advance where evidence may be found and where segregation is practically difficult in digital environments.
  • United States v. Loy, 191 F.3d 360 (3d Cir. 1999) (quoting United States v. Leon, 468 U.S. 897 (1984)): Supported the good-faith exception; even if a defect existed, suppression would not follow unless the warrant was so facially deficient that reasonable officers should have recognized illegality.
  • United States v. Yamba, 506 F.3d 251 (3d Cir. 2007) (quoting Minnesota v. Dickerson, 508 U.S. 366 (1993)): Supplied the “plain view” doctrine’s elements and validated using items discovered in plain view during a lawful search to support later warrants.

The Malave suppression analysis is built on two reinforcing pillars: (1) a robust nexus (Malave himself pointed officers to his phone for an alibi) and (2) the practical realities of digital searches under Stabile, which can justify broad downloads when evidence could be distributed across apps, media, and deleted data. The court then added doctrinal redundancy: even if overbroad, Leon/Loy good faith would salvage the search; and because the initial search was lawful, plain-view discovery could support a later warrant under Yamba/Dickerson.

7. Authentication and plain-error review

  • States v. Womack, 55 F.4th 219 (3d Cir. 2022): Provided plain-error review because Malave did not object at trial.
  • United States v. Turner, 718 F.3d 226 (3d Cir. 2013): Stated that the authentication burden under Rule 901(a) is “slight” and requires only a prima facie showing.
  • United States v. Goichman, 547 F.2d 778 (3d Cir. 1976): Reinforced that once a prima facie showing is made, authenticity becomes a jury question.

8. Relevant conduct attribution in conspiracies

  • United States v. Collado, 975 F.2d 985 (3d Cir. 1992): Supplied the key limiting framework—only conduct within the scope of the jointly undertaken activity, in furtherance, and reasonably foreseeable may be attributed, and the inquiry depends on the defendant’s degree of involvement.
  • United States v. West, 643 F.3d 102 (3d Cir. 2011): Provided clear-error review for relevant-conduct determinations.

The court applied Collado in a way that highlights leadership: the more the sentencing court finds that a defendant shaped the venture’s norms (here, violence and sex trafficking), the easier it becomes to treat co-conspirators’ acts as within the jointly undertaken activity and foreseeable—provided the district court makes fact findings tying leadership to scope and furtherance.

9. Sufficiency of the evidence and attempt liability

  • United States v. Lore, 430 F.3d 190 (3d Cir. 2005): “Extremely high” burden on sufficiency challenges.
  • United States v. Cothran, 286 F.3d 173 (3d Cir. 2002): The governing lens—view evidence in the light most favorable to the government; sustain if any rational juror could find guilt beyond a reasonable doubt.
  • United States v. Pawlowski, 682 F.3d 205 (3d Cir. 2012): Central to attempt liability; requires intent plus a “substantial step.”
  • Gov't of V.I. v. Isaac, 50 F.3d 1175 (3d Cir. 1995): Conflicting testimony does not equal insufficiency; credibility belongs to the jury.
  • United States v. Engle, 676 F.3d 405 (4th Cir. 2012): Cited (and implicitly rejected) for a probability-of-completion gloss; the Third Circuit reiterated it has not adopted that standard.
  • United States v. Lee, 612 F.3d 170 (3d Cir. 2010): Plain-error review for sufficiency theories not preserved below (applied to Newson).

10. Interstate commerce evidence (sex-trafficking conspiracy)

  • Hotel & Restaurant Emps. & Bartenders Int'l Union Loc. 54 v. Danziger, 709 F.2d 815 (3d Cir. 1983): Supported the proposition (in the panel’s plain-error posture) that activity involving hotels/places of public accommodation affects interstate commerce.
  • United States v. MacEwan, 445 F.3d 237 (3d Cir. 2006): The Internet is a channel/instrumentality of interstate commerce, supporting jurisdictional elements where online ads were used.

B. Legal Reasoning

1. Joinder and trial management in violent multi-defendant conspiracies

The court treated joint trial as the norm, especially in conspiracies, and prejudice as something typically curable through instructions and adversarial presentation. The key reasoning move is institutional: juries are presumed to follow limiting instructions, and severance is exceptional. Goode’s theory—spillover prejudice from graphic violence—was not enough without stronger indicators such as irreconcilable defenses, inability to segregate evidence, or trial structures that effectively prevented individualized consideration.

2. “Teaching experts” and the Rule 702 “fit” requirement

The defendants’ central Rule 702 attack was that the experts spoke in generalities and indirectly vouched for victim-witnesses by describing patterns resembling the prosecution’s narrative. The panel responded by tying the generalities to statutory elements: gang dynamics to whether an “enterprise” exists under RICO; sex-trafficking dynamics to whether conduct constitutes “force, fraud, or coercion” under 18 U.S.C. § 1591. This “element-linking” approach is crucial: it frames general testimony as helping jurors understand terms and patterns beyond ordinary experience rather than commenting on credibility.

3. Digital search warrants: nexus, breadth, and practical necessity

Malave’s suppression arguments attacked both the nexus (why his phone was connected to the assault) and the scope (whether police exceeded an “alibi-checking” mission). The court’s resolution rested heavily on Malave’s own conduct: he directed officers to his phone as an alibi source, which supplied nexus. For scope, the warrant application described the realistic possibility that evidence could reside anywhere across the device, including media and deleted data. Under United States v. Stabile, that justified a broad extraction.

The court then layered fallback doctrines: even if the warrant were defective, officers were entitled to rely on it absent obvious defects (United States v. Loy; United States v. Leon). And because the original search was lawful, evidence found “in plain view” could support a later federal warrant (United States v. Yamba; Minnesota v. Dickerson).

4. Sentencing: enhancements, relevant conduct, and harmlessness

For Goode, the panel emphasized deference to sentencing factfinding (clear-error review) and underscored harmlessness: even if multiple guideline disputes were resolved in Goode’s favor, the guideline range would be the same. This is a pragmatic appellate posture: a defendant must show not only error but consequential error.

For Malave, the court’s relevant-conduct reasoning hinged on leadership and organizational influence. Applying United States v. Collado, it credited district court findings that Malave fostered a violent enforcement culture and profited from trafficking occurring in the boarding house—findings that widened what could be treated as within the “jointly undertaken activity” and foreseeable. The opinion also treated harmlessness as independently dispositive because Malave’s offense level remained at life regardless.

5. Attempt liability: substantial step over probability-of-completion

Person’s attempt argument (that the victim’s refusal showed the trafficking was unlikely to succeed) invited the court to adopt a probability assessment akin to the language cited from United States v. Engle. The panel declined, reaffirming Third Circuit attempt doctrine: intent plus substantial step (United States v. Pawlowski). On the facts, photographing the victim for online advertisement, coercive statements about leaving, and physical intimidation were sufficient for a rational juror to find a substantial step.

C. Impact

  • Digital-search litigation: Even as nonprecedential, the opinion illustrates how the Third Circuit is likely to evaluate nexus and scope in smartphone searches: defendant-provided linkage (e.g., “my phone proves my alibi”) strengthens probable cause; broad extraction is easier to justify when the warrant application explains evidence could exist across formats and deleted spaces (echoing Stabile).
  • Rule 702 in trafficking and gang cases: The “element-linking” justification (gang dynamics → RICO enterprise; trafficking dynamics → “force, fraud, or coercion”) provides a roadmap for admitting contextual experts while attempting to avoid impermissible vouching.
  • Attempt standard clarity: The court’s explicit statement that it has not adopted a probability-of-success test, and its reaffirmation of the “substantial step” standard, signals resistance to defenses built around victim resistance or incomplete execution where coercive preparatory acts are proven.
  • Sentencing appeals: The opinion reinforces the centrality of harmless error when the guideline range remains unchanged and demonstrates how leadership findings can expand relevant conduct attribution under Collado.
  • Appellate practice: The jurisdiction discussion underscores that Rule 4(b) issues can be forfeited by the government; defense counsel still must file timely notices, but the government’s position may determine whether the appeal proceeds (Manrique v. United States).

IV. Complex Concepts Simplified

  • RICO “enterprise” (context): An “enterprise” is an organized structure through which people conduct criminal activity. Expert testimony on hierarchy, rules, and enforcement can help jurors decide whether a group is more than a loose association.
  • Rule 702 “fit”: Even a qualified, reliable expert can be excluded if their testimony does not help the jury decide something relevant. Here, general explanations of gang/trafficking dynamics were deemed helpful because they related to statutory elements.
  • Fourth Amendment “nexus”: There must be a logical connection between the place searched (a phone) and the crime. Malave created that connection by telling police his phone contacts could establish his alibi.
  • Digital “broad extraction”: Courts often allow copying large sets of digital data when evidence might be scattered through many apps and file types and cannot feasibly be isolated on the spot (as in United States v. Stabile).
  • Good-faith exception (Leon): Even if a warrant later turns out to be flawed, evidence may still be used if officers reasonably relied on the warrant and the defect was not obvious.
  • Plain view: If police are lawfully searching and they immediately recognize evidence of another crime, they may seize/use it under specific conditions (lawful vantage point, immediately apparent incriminating character, lawful access).
  • Relevant conduct (Guidelines): Sentencing can include acts by others if they were within the defendant’s agreed-upon criminal activity, done to further it, and reasonably foreseeable—an especially important doctrine in conspiracies.
  • Attempt “substantial step”: The government need not prove the crime was likely to succeed; it must prove intent and a concrete step that strongly corroborates that intent (e.g., coercive recruitment actions, arranging advertisements, physical intimidation).

V. Conclusion

The Third Circuit’s decision in United States v. Goode, Malave, Person, and Newson affirms sweeping convictions arising from a gang-driven drug and sex-trafficking enterprise. The opinion is most significant for its practical, doctrinally layered approach to (1) broad digital searches supported by nexus and reinforced by good faith and plain view, (2) admission of “teaching expert” testimony where linked to statutory elements, (3) sentencing attribution for leaders under the relevant-conduct framework, and (4) reaffirmation that Third Circuit attempt liability turns on intent and a substantial step—not on the probability of completion.

Even as a nonprecedential decision, it functions as a detailed field guide to how the Third Circuit applies established doctrines in complex RICO and sex-trafficking trials, and it signals the kinds of factual showings (clear limiting instructions; careful warrant affidavits; element-tethered expert testimony; leadership findings at sentencing) that make appellate reversal unlikely.
