Roadside Evasion During an Ongoing Drug Conspiracy Is Nontestimonial: United States v. Brown

Court: United States Court of Appeals for the Fifth Circuit
Date: October 20, 2026
Appeals: Nos. 25-40300 and 25-40402
Disposition: Convictions and sentences affirmed.

Precedential status: The per curiam opinion expressly states that it is not designated for publication under Fifth Circuit Rule 47.5. It principally applies established doctrine rather than announces a new, generally binding rule.

1. Introduction

In United States v. Brown, the Fifth Circuit considered consolidated appeals by Quanita Sherries Brown and Clarence Nero following their convictions for conspiring to possess heroin and fentanyl with intent to distribute, in violation of 21 U.S.C. § 846. Their prosecution arose from a Texas traffic stop that uncovered substantial quantities of both drugs concealed behind a speaker in a rental van.

Both defendants challenged the sufficiency of the evidence and the admission of expert testimony concerning fentanyl distribution. Nero separately challenged the removal of a prospective juror and the admission of Brown’s roadside statements. Brown sought a sentencing reduction for allegedly playing a minor role.

The opinion’s most distinctive constitutional application concerns Brown’s attempts to mislead police while the drug shipment remained underway. The court treated those statements as advancing an ongoing conspiracy and therefore as nontestimonial, notwithstanding that they were made to law-enforcement officers. The decision also illustrates how coordinated travel, communications, deceptive conduct, and concealed drugs can collectively establish a trafficking conspiracy without direct evidence identifying every participant in the distribution chain.

2. Background and Procedural History

In February 2022, Brown flew one-way from Houston to Phoenix. Nero, her boyfriend, had rented a van and driven it from New Orleans to Phoenix approximately one week earlier. After Brown arrived, Nero texted her the location of the parked van, which she collected.

The next morning, an interdiction officer stopped Brown on Texas State Highway 380 for a traffic infraction. Brown said she was returning to Houston after taking her grandchildren to Flagstaff. License-plate-reader records and receipts found in her purse contradicted that account. Nero remained on the telephone with her throughout the stop.

Brown consented to a search. Officers found a screwdriver bearing signs of recent use and observed changes in Brown’s demeanor when questioning her about it. After a police dog alerted, officers identified tooling marks on a panel, removed it, and used the screwdriver to remove a speaker. Behind the speaker were vacuum-sealed packages containing 1,979.3 grams of fentanyl and 1,934.7 grams of heroin. Testimony estimated that the fentanyl alone could produce approximately 993,350 pills, worth between $1,986,700 and $9,933,500.

Data extracted from Brown’s telephone revealed years of communications with Nero concerning border checkpoints, a “company,” travel, pills, and risks associated with their activities. The government also presented evidence of extensive coordinated travel and Nero’s rental of more than fifty vehicles since January 2019.

A jury convicted both defendants. The district court sentenced Brown to 188 months’ imprisonment and Nero to 264 months. Their appeals were consolidated.

3. Summary of the Opinion

Issue Review Holding
Sufficiency of conspiracy evidence De novo, viewing the evidence favorably to the verdict The combined physical, travel, communications, and roadside evidence permitted a rational jury to find a knowing agreement and voluntary participation.
Expert disclosure and relevance Plain error Neither defendant requested disclosure under Rule 16. The government nevertheless provided notice, and the testimony was relevant to distribution and knowledge.
Removal of Juror 31 Clear abuse of discretion The district court could credit the juror’s admitted defense-favoring bias despite his qualified assurance that he could follow instructions.
Confrontation Clause Plain error Brown’s roadside statements furthered the ongoing conspiracy by attempting to avoid detection and were nontestimonial.
Minor-role sentencing adjustment Plain error Brown’s sustained involvement, planning communications, and transportation of valuable drugs did not require a two-level reduction.

The court rejected every asserted ground for relief and affirmed the judgments.

4. Analysis: Legal Reasoning and Precedents

A. Circumstantial Evidence and the Conspiracy Convictions

Governing precedents

  • United States v. Alaniz, 726 F.3d 586, 600 (5th Cir. 2013), supplied de novo review for the defendants’ preserved sufficiency challenges.
  • United States v. Scott, 159 F.3d 916, 920 (5th Cir. 1998), supplied the controlling inquiry: whether any rational factfinder, viewing the evidence and reasonable inferences favorably to the verdict, could find the essential elements beyond a reasonable doubt.
  • United States v. Freeman, 56 F.4th 1024, 1025 (5th Cir. 2023), established that the sufficiency standard does not change when the prosecution relies on circumstantial rather than direct evidence.
  • United States v. Isgar, 739 F.3d 829, 835 (5th Cir. 2014), quoting United States v. Moreno-Gonzalez, 662 F.3d 369, 372 (5th Cir. 2011), emphasized that appellate sufficiency review is highly deferential to the verdict.
  • United States v. Grant, 683 F.3d 639, 642 (5th Cir. 2012), quoting United States v. Loe, 262 F.3d 427, 432 (5th Cir. 2001), reserved credibility determinations and the weighing of conflicting evidence to the jury. The court also relied on United States v. Grant when rejecting the defendants’ competing interpretations of their conduct.
  • United States v. Vargas-Ocampo, 747 F.3d 299, 303 (5th Cir. 2014) (en banc), supplied the conspiracy elements: an agreement to violate narcotics laws, the defendant’s knowledge of that agreement, and voluntary participation.

Application

The court assessed the evidence cumulatively rather than demanding that any single fact independently establish guilt. Nero’s procurement and positioning of the van, Brown’s one-way flight to retrieve it, their coordinated communications, and the concealed bulk narcotics supported an inference of an agreed undertaking. Their broader rental and travel history strengthened the inference that this was a recurring enterprise rather than an isolated innocent journey.

Brown’s inconsistent travel account supplied additional evidence of knowledge. Her receipts and license-plate-reader records contradicted her explanation, while her reaction to questions about the screwdriver linked her conduct to an implement that officers later used to access the concealed drugs.

The telephone evidence gave further context to otherwise ambiguous conduct. References to border-screening technology, risks, pills, a “company,” and Nero as “CEO” allowed the jury to infer a criminal partnership. The court did not treat these expressions as inherently criminal; their significance arose from their combination with the physical evidence and coordinated travel.

The defendants argued that the government had not identified who supplied, packaged, installed, or would receive the drugs. The court rejected that proposed evidentiary requirement. Establishing these defendants’ knowing agreement did not require reconstructing every stage of the trafficking operation.

Likewise, the possibility that their communications reflected a romantic relationship did not invalidate the verdict. A romantic relationship and a criminal partnership could coexist. Nor did the difficulty of discovering the hidden drugs compel an inference of ignorance when substantial additional evidence supported knowledge.

Doctrinal significance: De novo review does not mean a fresh trial on the appellate record. The court independently applies the legal sufficiency test while respecting the jury’s authority to choose among reasonable interpretations of the evidence.

B. Expert Disclosure, Relevance, and the Importance of Prejudice

Governing precedents and rules

United States v. Vargas, 580 F.3d 274, 278 (5th Cir. 2009), required plain-error review because neither defendant objected to Captain Jeff Davis’s testimony at trial.

Federal Rule of Criminal Procedure 16(a)(1)(G)(i) makes the government’s specified expert-disclosure obligation dependent on a defense request. The defendants made no such request. Nevertheless, the government announced its intention to present fentanyl-distribution expert testimony and subsequently identified Davis.

The opinion also cited United States v. Cuellar, 478 F.3d 282, 293–94 (5th Cir. 2007) (en banc), for the importance of explaining how omitted disclosure information would have supplied additional grounds for cross-examination. It expressly acknowledged that decision’s reversal on other grounds in Regalado Cuellar v. United States, 553 U.S. 550 (2008). The citation supported the prejudice analysis, not a suggestion that the earlier judgment remained intact in every respect.

Application

The principal disclosure holding was narrow: without a defense request, the disclosure duty invoked by the defendants had not been triggered. The government had, in any event, voluntarily provided notice.

The court separately addressed a possible deficiency in that voluntary disclosure. Its wording tracked Rule 16’s pre-2022 language and might not have included everything required by the amended provision. Even assuming such an omission, the defendants did not demonstrate an effect on substantial rights under Federal Rule of Criminal Procedure 52(b). In particular, they did not identify additional cross-examination opportunities that fuller information would have created.

This distinction matters. The opinion should not be read as finding that an older-form notice necessarily satisfies every current disclosure requirement. Its reasoning depended on the absence of a triggering request and, alternatively, the absence of demonstrated prejudice.

Davis’s testimony was also relevant. His explanation of fentanyl’s distribution in pill form and the equipment used to produce pills gave context to the defendants’ recent messages about pills and suppliers. His quantity testimony supported an inference of intended distribution, while the drugs’ value supported the court’s assessment of knowledge and the defendants’ joint efforts to complete the shipment.

The holding does not establish that all fentanyl must be distributed as pills, or that every valuation opinion is automatically admissible. It approves the evidentiary connections identified in this record.

C. A Prospective Juror’s Assurance Does Not Necessarily Eliminate Admitted Bias

Governing precedents

  • United States v. Dejean, 988 F.3d 813, 816 (5th Cir. 2021), quoting United States v. Hinojosa, 958 F.2d 624, 631 (5th Cir. 1992), recognized the district court’s broad discretion in assessing juror impartiality and required a clear abuse of discretion for reversal.
  • United States v. Wharton, 320 F.3d 526, 535 (5th Cir. 2003), quoting Soria v. Johnson, 207 F.3d 232, 242 (5th Cir. 2000), supplied the substantive standard: whether a prospective juror’s views would prevent or substantially impair performance of the juror’s duties under the instructions and oath.
  • Mu'Min v. Virginia, 500 U.S. 415, 424 (1991), quoting Rosales-Lopez v. United States, 451 U.S. 182, 188 (1981), explained why appellate courts defer: trial judges assess demeanor and credibility that a transcript cannot fully preserve.

Application

Juror 31 stated that he would favor the defense. Although he later said he believed he could follow the court’s instructions, he also retained “reservations.” The district judge concluded that his admission of bias remained significant and granted the government’s challenge for cause.

The Fifth Circuit refused to treat the juror’s qualified assurance as conclusive rehabilitation. The trial judge had observed his tone, demeanor, and body language and could evaluate the assurance against his earlier admission.

The decision therefore does not authorize removal merely because a prospective juror expresses an unpopular view. It affirms a contextual determination that admitted partiality was not adequately dispelled. The constitutional objective is an impartial jury, not preservation of a juror predisposed toward either side.

D. Roadside Deception and the Confrontation Clause

Governing precedents

  • United States v. Acosta, 475 F.3d 677, 680 (5th Cir. 2007), supplied plain-error review because Nero did not object at trial.
  • United States v. King, 93 F.4th 845, 851 (5th Cir. 2024), quoting Crawford v. Washington, 541 U.S. 36, 53–54 (2004), stated the restriction on admitting an unavailable witness’s testimonial statements without a prior opportunity for cross-examination.
  • United States v. Duron-Caldera, 737 F.3d 988, 992–93 (5th Cir. 2013), quoted through United States v. King, supplied the primary-purpose formulation: testimonial statements principally establish or prove past events potentially relevant to a later prosecution.
  • United States v. Holmes, 406 F.3d 337, 348 (5th Cir. 2005), explained that statements made during and in furtherance of a conspiracy are generally nontestimonial.
  • United States v. Jackson, 636 F.3d 687, 694 (5th Cir. 2011), reinforced that co-conspirator principle.
  • United States v. Gurrola, 898 F.3d 524, 535 n.17 (5th Cir. 2018), described the circuit’s treatment of co-conspirator statements as nontestimonial as well settled.

The opinion noted that certiorari in United States v. King was denied under the name Diggs v. United States, 145 S. Ct. 213 (2024). That denial forms part of the case’s procedural history; it is not an independent Supreme Court endorsement of the underlying reasoning.

Application

Nero argued that Brown’s statements about the rental van, her supposed travels, and the screwdriver implicated him even though she did not testify and could not be cross-examined.

The court focused on the purpose and timing of those statements. Officers had not yet deployed the canine or discovered the drugs. Brown was still transporting the shipment. Her explanations sought to make the journey appear innocent, avoid discovery, and permit the transportation to continue.

Accordingly, the statements served the conspiracy rather than an evidentiary investigation intended to establish facts for prosecution. Their immediate function was to deceive officers and preserve the ongoing operation. The court therefore classified them as nontestimonial and found no Confrontation Clause violation.

Important limitation: The holding is not that every statement by a conspirator, or every statement made during a traffic stop, falls outside the Confrontation Clause. The court relied on an active trafficking operation and statements furthering its objectives. It did not decide the treatment of a later confession, a formal accusation against an accomplice, or concealment occurring after the conspiracy’s objectives had ended.

Nor should the constitutional conclusion be confused with a universal hearsay exemption. Whether a statement is testimonial and whether it satisfies applicable evidence rules are distinct inquiries. Here, the court resolved the confrontation challenge through the statements’ character as communications furthering the conspiracy.

E. Courier Status Does Not Automatically Establish a Minor Role

Governing precedents

  • United States v. Martinez-Larraga, 517 F.3d 258, 272 (5th Cir. 2008), required plain-error review because Brown did not request the adjustment or object on that ground below.
  • United States v. Martinez, 921 F.3d 452, 483 (5th Cir. 2019), identified relevant considerations: understanding the activity’s scope, participation in planning, decision-making authority, the nature and extent of participation, and anticipated benefit.
  • United States v. Gallegos, 868 F.2d 711, 713 (5th Cir. 1989), established that a courier need not be substantially less culpable than the average participant.

Application

Brown sought a two-level reduction under U.S.S.G. § 3B1.2(b). Because she had not raised the issue at sentencing, the appellate question was whether the district court plainly erred by failing to award it on its own initiative.

The record supported substantial participation. Brown transported a valuable shipment, communicated about planning and operational decisions, and had an extended history of similar travel and exchanges with Nero. Her role was therefore not adequately described by the bare label “courier.”

The court did not hold that carrying a large quantity of drugs categorically defeats a minor-role adjustment. Its assessment rested on Brown’s broader, sustained involvement. Nor did Nero’s supervisory role compel a finding that Brown was a minor participant: being less authoritative than another participant is not necessarily the same as being substantially less culpable than the relevant average participant.

5. Potential Impact and Limits

Conspiracy prosecutions: The opinion illustrates the force of mutually reinforcing circumstantial evidence. Travel records, messages, concealment, and deceptive explanations may establish a knowing agreement even where the government cannot identify the entire supply chain. Conversely, the holding should not be reduced to the proposition that association or unexplained travel alone proves conspiracy.

Roadside statements: The decision gives a fact-specific example of deceptive statements to police that advance a crime still in progress. Future disputes may turn on whether the underlying criminal objective remained active and whether a statement sought to facilitate that objective or instead created evidence for prosecution.

Expert practice: Defense counsel should make the request necessary to trigger Rule 16’s expert-disclosure requirements and identify concrete prejudice from deficient disclosures. Prosecutors should not read the result as permission to disregard the amended rule once its requirements apply.

Trial and sentencing preservation: Three issues—expert testimony, confrontation, and the minor-role adjustment—received plain-error review because they were not raised below. The opinion underscores the practical importance of timely objections and a developed factual record.

Sentencing: The decision reinforces individualized role analysis. A transportation function neither guarantees nor categorically excludes a reduction; knowledge, planning, discretion, and the extent of participation remain important.

Because the opinion is unpublished and heavily dependent on its record, its principal value lies in illustrating established Fifth Circuit doctrine rather than creating a broad new rule.

6. Complex Concepts Simplified

Conspiracy
An agreement to commit an unlawful objective, knowingly and voluntarily joined by the defendant. The agreement may be inferred from coordinated conduct rather than proved by an express written or spoken pact.
Circumstantial evidence
Evidence that supports a conclusion through inference—for example, coordinated travel and coded communications. It is not legally inferior to direct evidence.
De novo review
Independent appellate review of a legal question. For sufficiency claims, that review still views the evidence favorably to the verdict and does not reweigh witness credibility.
Plain error
A demanding standard for claims not properly raised below. Generally, the defendant must show a clear error affecting substantial rights; correction also depends on a serious effect on the fairness, integrity, or public reputation of judicial proceedings.
Challenge for cause
A request to remove a prospective juror for a legally sufficient reason, such as bias that substantially impairs impartial service.
Testimonial statement
A statement whose primary purpose is to establish past events for potential criminal prosecution. Such statements trigger confrontation protections when offered against an accused.
Statement in furtherance of a conspiracy
A statement that helps advance the unlawful undertaking. Brown’s misleading explanations qualified because they sought to prevent discovery while transportation of the drugs continued.
Minor-role adjustment
A sentencing reduction for a qualifying lesser participant. A job description such as “courier” does not itself establish entitlement.
Sua sponte
Action taken by a court on its own initiative, without a party requesting it. Brown argued that the sentencing court should have awarded the role reduction this way.

7. Conclusion

The Fifth Circuit affirmed Brown’s and Nero’s convictions and sentences because the combined evidence supported a knowing trafficking agreement and none of the asserted trial or sentencing errors justified reversal.

The opinion’s central constitutional lesson is that roadside deception intended to keep an ongoing drug shipment moving may constitute nontestimonial co-conspirator statements. Its broader lessons concern cumulative proof, respect for jury factfinding, contextual assessment of juror bias, individualized sentencing roles, and the importance of preserving objections. As an unpublished decision, it is best understood as a concrete application of existing doctrine, not a wholesale expansion of it.
