Clarifying the Firearm–Drug Nexus: Supplemental Instructions and Alternative-Sentence Review

1. Introduction

This appeal arose from a late-night traffic stop in Ocala, Florida, that led to the discovery of drugs, drug paraphernalia, and a loaded handgun. Michael Kendrick challenged both the investigation and the resulting federal prosecution, arguing that the stop was unlawful, his custodial statements were inadmissible, the evidence was insufficient, a supplemental jury instruction prejudiced his defense, and his sentence was improperly calculated and excessive.

Writing for a unanimous panel, Judge Abudu rejected those challenges. The opinion’s most practically significant conclusions concern two recurring trial and appellate problems: how a judge may clarify the relationship required between a firearm and drug trafficking, and when an appellate court may affirm a sentence without resolving a disputed Sentencing Guidelines calculation.

The court approved a neutral supplemental instruction identifying established factors relevant to whether firearm possession furthered drug trafficking. It also applied the alternative-sentence framework: because the sentencing judge expressly would have imposed the same sentence under either disputed Guidelines calculation, the appellate court assumed Kendrick’s preferred calculation and examined whether the sentence remained substantively reasonable.

2. Background and Procedural History

The stop and investigation

At approximately 1:30 a.m. on July 6, 2019, Officer Shelby O’Grady observed Kendrick driving in an area she described as having substantial violent and drug-related crime. She testified that, while observing his vehicle through her side-view mirror, she saw him stop within a crosswalk rather than before it, violating Florida Statutes § 316.123(2)(a).

O’Grady followed Kendrick as he entered and left one driveway and then parked in another. When she activated her emergency lights, Kendrick exited his vehicle, apparently dropped a small white object, and fled despite commands to return. O’Grady pursued him and found him hiding in bushes. Officers recovered two cell phones and $1,844 in cash.

The object beside the driver’s door was a plastic bag containing eutylone. After a police dog alerted to narcotics, officers searched the vehicle and discovered drug paraphernalia and a loaded semiautomatic handgun beneath the passenger seat. Testing identified DNA from four people, including Kendrick, on the firearm; no usable fingerprints were recovered.

Federal arrest and questioning

After a federal indictment, officers arrested Kendrick in February 2020 in connection with his appearance at a state courthouse. A task force officer read him his Miranda rights. Kendrick said he understood them and signed a written waiver before answering questions during transportation to federal court.

During the conversation, Kendrick expressed uncertainty about how the process worked and referred to having been read his rights. He nevertheless continued speaking, stated that he had nothing to hide, disputed ownership of the firearm, and denied that drugs had fallen from his lap.

Suppression, trial, and sentence

The district court denied Kendrick’s suppression motion after adopting a magistrate judge’s findings. It credited O’Grady’s account of the traffic violation over a defense investigator’s reconstruction and found Kendrick’s waiver valid.

At trial, the defense contested the government’s interpretation of the physical evidence. Witnesses suggested that others had occupied the vehicle, questioned possible DNA cross-contamination, and offered legitimate explanations for the cash. The jury nevertheless convicted Kendrick of:

1. Possessing a controlled substance with intent to distribute, under 21 U.S.C. § 841(a)(1);
2. Possessing a firearm in furtherance of that drug-trafficking crime, under 18 U.S.C. § 924(c)(1)(A)(i); and
3. Being a felon in possession of a firearm, under 18 U.S.C. § 922(g)(1).

During deliberations, the jury requested clarification of “in furtherance.” Over a defense objection, the judge supplemented the original instruction with eight nonexclusive factors drawn from circuit precedent.

At sentencing, the court accepted the government’s proposed higher base offense level. It imposed concurrent 84-month sentences on the drug and felon-in-possession counts, followed by the mandatory consecutive 60 months on the § 924(c) count, producing a total of 144 months.

3. Summary of the Opinion

• Traffic stop: The credited observation of a Florida traffic violation supplied probable cause. The record did not justify overturning the suppression court’s credibility findings.
• Custodial statements: Kendrick voluntarily, knowingly, and intelligently waived his rights. His later expression of uncertainty was not an unambiguous request for counsel or invocation of silence.
• Sufficiency: The video, physical evidence, expert testimony, and DNA evidence permitted a rational jury to find every challenged element beyond a reasonable doubt.
• Supplemental instruction: The judge accurately and neutrally clarified the firearm–drug nexus. Defense counsel’s failure to address the listed factors in closing argument did not establish prejudice.
• Sentence: The court did not decide the disputed Guidelines issue. Assuming Kendrick’s lower range, it held that the same 144-month sentence remained substantively reasonable.

4. Analysis: Precedents and Legal Reasoning

A. Standards of review shaped the appeal

The opinion distinguishes questions that appellate judges reconsider independently from questions on which they defer to the trial court or jury.

• United States v. Pierre, 825 F.3d 1183 (11th Cir. 2016), and United States v. McCullough, 851 F.3d 1194 (11th Cir. 2017): These decisions supply the mixed standard for suppression rulings: factual findings receive clear-error review, while legal conclusions receive de novo review. That distinction mattered because Kendrick’s traffic-stop challenge depended heavily on which witness the court believed.
• United States v. Peters, 403 F.3d 1263 (11th Cir. 2005): Sufficiency is reviewed de novo, but the evidence must be viewed favorably to the verdict. Independent legal review therefore does not authorize an appellate court to retry factual disputes.
• United States v. Alli, 184 F.4th 1280 (11th Cir. 2026): The court cited this decision for abuse-of-discretion review of a preserved challenge to jury instructions. Kendrick preserved his objection, but preservation did not eliminate the trial judge’s legitimate discretion to clarify the law.
• United States v. Grushko, 50 F.4th 1 (11th Cir. 2022): This decision distinguishes de novo review of Guidelines application from abuse-of-discretion review of sentencing reasonableness. The panel ultimately avoided the disputed Guidelines question and proceeded to reasonableness review under the alternative-sentence doctrine.

B. The traffic stop: objective justification and factual credibility

1. A traffic violation supplied the necessary justification

The court began with the Fourth Amendment’s protection against unreasonable searches and seizures. Whren v. United States, 517 U.S. 806 (1996), supplied the constitutional framework for traffic stops. Delaware v. Prouse, 440 U.S. 648 (1979), and West v. Davis, 767 F.3d 1063 (11th Cir. 2014), established that a traffic stop constitutes a seizure of the driver and passengers.

Under Heien v. North Carolina, 574 U.S. 54 (2014), and United States v. Campbell, 26 F.4th 860 (11th Cir. 2022) (en banc), reasonable suspicion of a legal violation ordinarily suffices for a traffic stop. Here, however, the district court found the stronger justification of probable cause.

The panel followed United States v. Clark, 32 F.4th 1080 (11th Cir. 2022), in declining to undertake a separate reasonable-suspicion analysis once probable cause was established. Drawing on United States v. Pierre, the court asked whether the facts known to law enforcement would cause a reasonably cautious person to believe an offense had occurred.

The relevant offense was specific: Florida law required Kendrick to stop at the marked line or, if none existed, before entering the crosswalk. The court did not treat the neighborhood’s crime rate or Kendrick’s presence there as sufficient by themselves.

2. Investigative motives did not invalidate an objectively lawful stop

O’Grady acknowledged actively looking for lawful reasons to stop vehicles so she could investigate activity in the area. That admission did not defeat the stop. United States v. Andres, 960 F.3d 1310 (11th Cir. 2020), citing United States v. Harris, 526 F.3d 1334 (11th Cir. 2008), establishes that an officer’s subjective motive does not invalidate objectively sufficient grounds for a stop.

The important distinction is between a genuine traffic violation used as an investigative opportunity and a stop unsupported by any adequate objective basis. The opinion approves the former; it does not authorize stops merely because an officer wishes to investigate someone.

3. The credibility dispute was decisive

Kendrick’s central argument was that O’Grady could not have observed the violation from her claimed position. The magistrate judge nevertheless credited her account because she knew the area, described tracking the vehicle’s illuminated headlights, and gave testimony consistent with her recorded account that night.

The defense reconstruction was less persuasive because the investigator used a different vehicle and mirror, lacked comparable familiarity with the location, and did not recreate the nighttime observation of an approaching vehicle with its headlights on.

United States v. Ramirez-Chilel, 289 F.3d 744 (11th Cir. 2002), supplies especially deferential review of credibility determinations. Such findings are not rejected unless they contradict natural laws or are so facially improbable that no reasonable factfinder could accept them. Kendrick’s evidence did not meet that demanding threshold. Under United States v. Harris, the credited observation of the traffic violation therefore supported probable cause.

4. The evidence seizures also had distinct supporting grounds

The opinion’s footnote addressed the discovery of the drugs and the vehicle search separately:

• Scott v. City of Miami, 139 F.4th 1267 (11th Cir. 2025): The panel cited this decision in rejecting Kendrick’s contention that the officers lacked probable cause after initiating the lawful stop. The opinion’s brief treatment should not be expanded into a general rule that probable cause for a traffic offense automatically authorizes searching a vehicle for drugs.
• United States v. Smith, 459 F.3d 1276 (11th Cir. 2006): The court relied on the plain-view doctrine to uphold seizure of the bag outside the driver’s door, where officers had lawful access.
• United States v. Tamari, 454 F.3d 1259 (11th Cir. 2006), quoting United States v. Banks, 3 F.3d 399 (11th Cir. 1993): A drug-trained dog’s alert supplied probable cause to search the vehicle. This provided an additional, specific justification for finding and seizing the paraphernalia and firearm.

These distinctions preserve the separate legal questions of stopping a vehicle, seizing an object outside it, and searching its interior. The opinion does not independently resolve issues concerning prolongation of the stop or a contested canine’s reliability.

C. Custodial statements: waiver and later invocation are different questions

1. The governing waiver framework

Miranda v. Arizona, 384 U.S. 436 (1966), requires warnings before custodial interrogation to protect the privilege against compelled self-incrimination. United States v. Bernal-Benitez, 594 F.3d 1303 (11th Cir. 2010), explains both the warning requirement and the obligation to respect an invocation of protected rights.

Warnings alone do not make subsequent statements admissible. Under Colorado v. Spring, 479 U.S. 564 (1987), the suspect must validly waive the relevant rights. Colorado v. Connelly, 479 U.S. 157 (1986), places the burden on the government to establish waiver by a preponderance of the evidence.

The controlling two-part inquiry came from Moran v. Burbine, 475 U.S. 412 (1986), as applied in United States v. Bernal-Benitez:

1. Voluntariness: Was the waiver a free and deliberate choice rather than the product of intimidation, coercion, or deception?
2. Knowledge and understanding: Did the suspect understand the rights being abandoned and the consequences of abandoning them?

Hall v. Thomas, 611 F.3d 1259 (11th Cir. 2010), reinforces the independence of the second requirement: an uncoerced statement is not necessarily an informed one. Fare v. Michael C., 442 U.S. 707 (1979), supplies the totality-of-the-circumstances approach incorporated into this analysis.

2. Why Kendrick’s waiver was valid

The officers read Kendrick his rights, obtained his verbal acknowledgment that he understood them, and secured a signed waiver before questioning. The interrogation occurred during a relatively short car journey. The record disclosed no physical abuse, coercive deprivation, or educational or intellectual limitation undermining comprehension.

The setting outside a courthouse on a hot day did not, without more, invalidate the waiver. The court considered the circumstances together rather than treating discomfort or informality as dispositive.

The written waiver was important but not conclusive. North Carolina v. Butler, 441 U.S. 369 (1979), explains that an express waiver is ordinarily strong proof, but is neither invariably necessary nor sufficient. Consistently with United States v. Bernal-Benitez, the panel treated the signature as strong objective evidence supported by the surrounding conversation and conduct—not as a substitute for the constitutional inquiry.

3. Kendrick did not clearly withdraw his waiver

A valid initial waiver does not prevent a suspect from later invoking silence or counsel. The separate question was whether Kendrick did so when he said, in part, “I know you read me my rights and stuff I really don’t know.”

Davis v. United States, 512 U.S. 452 (1994), requires an unambiguous invocation of counsel. Berghuis v. Thompkins, 560 U.S. 370 (2010), applies the same clarity requirement to an invocation of silence. Ambiguous or equivocal references do not require officers to stop questioning.

Context defeated Kendrick’s argument. His remark arose while discussing another alleged occupant of the vehicle; he then said he had nothing to hide and continued answering questions. The panel interpreted the remark as uncertainty about the process, not a clear request to terminate questioning or obtain a lawyer.

Although the procedural history records that Kendrick initially asserted Sixth Amendment concerns, the appellate analysis focuses on Miranda waiver and invocation. The opinion should not be treated as separately resolving an undeveloped Sixth Amendment right-to-counsel question.

D. Sufficiency: cumulative evidence supported all three convictions

1. Appellate review did not permit reweighing the defense evidence

Jackson v. Virginia, 443 U.S. 307 (1979), asks whether any rational factfinder, viewing the evidence favorably to the prosecution, could find the essential elements beyond a reasonable doubt. Mamani v. Sanchez Bustamante, 968 F.3d 1216 (11th Cir. 2020), similarly permits reversal only when no rational factfinder could reach the verdict on the record.

Accordingly, the existence of competing explanations did not itself require acquittal. The jury could assess testimony about other occupants, legitimate cash sources, and possible DNA contamination. The appellate court’s task was to identify a rational evidentiary basis for the verdict, not choose which account it preferred.

2. Possession with intent to distribute

United States v. Poole, 878 F.2d 1389 (11th Cir. 1989), supplied the governing requirement of knowing possession and intent to distribute. The dashcam evidence supported possession by showing the bag falling from Kendrick as he exited. The cash, two phones, paraphernalia, and expert testimony about quantity and packaging supported the inference of distribution rather than personal use.

The reasoning was cumulative. The court did not hold that cash, multiple phones, or any other isolated circumstance automatically proves trafficking.

3. Felon in possession of a firearm

The court cited United States v. Palma, 511 F.3d 1311 (11th Cir. 2008), for the firearm-possession framework, while expressly noting its abrogation on other grounds by Rehaif v. United States, 588 U.S. 225 (2019).

Kendrick stipulated to felony status and the firearm’s interstate movement. The principal contested issue was possession. The loaded handgun’s location beneath the passenger seat of the car he drove, combined with his DNA on the weapon, allowed a rational inference of knowing actual or constructive possession.

The mixed DNA profile did not establish exclusive handling, but exclusive possession was not necessary to the panel’s reasoning. The evidence needed to support Kendrick’s possession, not eliminate every possibility that others also handled the gun.

The citation to Rehaif v. United States is important: § 922(g) also requires knowledge of the relevant prohibited status. The opinion’s abbreviated discussion should not be read as eliminating that requirement or as independently holding that a stipulation to felony status always resolves knowledge of status.

4. Possession “in furtherance” of drug trafficking

The most consequential substantive distinction concerns § 924(c). Possessing a gun while drugs happen to be nearby is not necessarily possessing it to advance drug trafficking.

United States v. Timmons, 283 F.3d 1246 (11th Cir. 2002), requires a nexus between the firearm and the drug-selling operation. It identifies eight nonexclusive considerations:

1. The type of drug activity;
2. The firearm’s accessibility;
3. The type of weapon;
4. Whether the weapon was stolen;
5. Whether possession was lawful or unlawful;
6. Whether the gun was loaded;
7. Its proximity to drugs or drug proceeds; and
8. The time and circumstances of its discovery.

The loaded, accessible handgun, the evidence of distribution, and the surrounding drugs, paraphernalia, and cash permitted an inference that the weapon furthered trafficking. The physical evidence was distributed between Kendrick, the area beside the driver’s door, and the vehicle; the analysis did not require every item to occupy one location.

The district court also relied on United States v. Dixon, 901 F.3d 1322 (11th Cir. 2018), when denying acquittal on this count. The supplied opinion identifies that decision as addressing “in furtherance,” but develops its own appellate analysis primarily through United States v. Timmons. It supplies no basis for attributing a separate, broader holding to United States v. Dixon.

The factors are not a checklist of additional statutory elements, and not every factor must favor the prosecution. Their purpose is to distinguish a functional relationship from coincidental proximity.

E. Supplemental instructions: accurate clarification outweighed claimed tactical disadvantage

The jury’s request for a more detailed definition triggered a judicial responsibility to address confusion. Bollenbach v. United States, 326 U.S. 607 (1946), requires clarification with “concrete accuracy.” United States v. Rodriguez, 765 F.2d 1546 (11th Cir. 1985), likewise recognizes an obligation to make reasonable efforts to answer jury questions.

That responsibility has limits. Under United States v. Lopez, 590 F.3d 1238 (11th Cir. 2009), judges possess considerable discretion over supplemental instructions but may not misstate the law or confuse the jury. Review considers the supplemental language together with the entire charge, indictment, evidence, and arguments.

The original instruction explained that a firearm must have “helped, promoted, or advanced” the crime. The supplement preserved that requirement and supplied the eight factors from United States v. Timmons. It expressly made the list nonexclusive and did not tell jurors which facts had been established or what verdict to return.

Kendrick did not contend that the supplement misstated the law. Instead, counsel argued that her closing had been tailored to the pattern instruction and had not addressed the newly enumerated factors. The panel found this insufficient: the judge was entitled to answer the jury accurately, and the explanation supplied a neutral legal framework rather than a prosecution-oriented factual argument.

The holding is therefore narrower than blanket approval of all post-closing supplements. It approves this accurate, responsive, non-directive clarification. Instructions that alter an element, distort the burden of proof, or effectively resolve factual disputes would present different questions.

F. Sentencing: an assumed Guidelines error did not require reversal

1. The disputed calculation remained unresolved

The initial calculation yielded an offense level of 14 and criminal history category VI, producing 37–46 months on the grouped drug and felon-in-possession counts. The government sought a base offense level of 20 under U.S.S.G. § 2K2.1(a)(4)(A), relying on a 2015 controlled-substance conviction. The district court sustained that objection, resulting in a 70–87-month range for those counts.

The appellate court did not decide whether that prior conviction justified the higher level. United States v. Keene, 470 F.3d 1347 (11th Cir. 2006), permitted it to bypass the dispute because the district judge expressly stated that the same sentence would be imposed regardless.

The second part of that framework was essential: the panel had to assume the Guidelines dispute should have been resolved in Kendrick’s favor and then test the sentence against that lower advisory range. An alternative-sentence statement alone was not the entire analysis.

2. The court assessed a substantial upward variance

On the defense-favored assumption, the applicable range was 37–46 months, plus the mandatory consecutive 60-month § 924(c) term. That produces an aggregate advisory benchmark of 97–106 months. The actual 144-month sentence was therefore 38 months above the upper end of that assumed aggregate benchmark.

United States v. Butler, 39 F.4th 1349 (11th Cir. 2022), requires due deference to a district court’s conclusion that the factors in 18 U.S.C. § 3553(a) justify a variance. Quoting United States v. Rosales-Bruno, 789 F.3d 1249 (11th Cir. 2015), it asks whether the outcome remains within the “ballpark of permissible outcomes.” The appellate court could consider the degree of deviation but could not substitute its own preferred sentence.

United States v. Irey, 612 F.3d 1160 (11th Cir. 2010) (en banc), supplies the limiting framework. Abuse of discretion occurs when the sentencing court neglects significantly relevant factors, gives significant weight to improper factors, or clearly misjudges the proper factors. Reversal requires a firm conviction that the sentence falls outside the reasonable range supported by the case.

3. Individualized reasons supported the sentence

The sentencing judge emphasized Kendrick’s extensive criminal history, repeated failures on supervision, flight from police, and the needs for deterrence and public protection. The judge also acknowledged his upbringing and absence of prior violent conduct but assigned those considerations less weight than recidivism and the seriousness of the offenses.

The panel held that this explanation satisfied the governing framework. The sentence’s position below the statutory maximums supported the result but did not replace the individualized analysis.

Two limits are especially important. First, the opinion does not establish that a conviction described simply as controlled-substance possession necessarily qualifies under § 2K2.1(a)(4)(A). Second, the alternative-sentence doctrine is not a general license to disregard accurate Guidelines calculations; it permits affirmance where the same-sentence declaration and reasonableness analysis establish that the disputed calculation would not change the outcome.

5. Potential Impact

Trial practice under § 924(c)

The opinion illustrates how judges may clarify “in furtherance” without directing the verdict. A legally accurate, nonexclusive factor instruction can help jurors distinguish mere firearm possession from possession that advances trafficking. Defense counsel should therefore anticipate the established nexus factors even when the initial charge uses only a shorter pattern definition.

Suppression litigation

The case highlights the importance of matching a defense reconstruction to the officer’s actual claimed observations. Differences in lighting, vehicle, mirror, and familiarity can substantially reduce its force. Once a trial court makes supported credibility findings, appellate reversal is difficult.

It also reinforces the need to distinguish an invalid initial waiver from a later invocation. General uncertainty about the process does not necessarily invalidate a previously informed waiver or clearly communicate a wish to stop questioning.

Sentencing and appellate preservation

For sentencing judges, the decision demonstrates the value of an express alternative sentence supported by a detailed § 3553(a) explanation. For defendants, it shows that identifying a possible Guidelines error may not suffice: counsel must also confront the reasonableness of the same sentence under the lower range.

Limits on future reliance

Because the opinion is unpublished, its principal value is persuasive and illustrative. It does not replace the published authorities it applies. Its factual conclusions also remain context-dependent: shared DNA is not automatically sufficient in every possession case, firearm proximity does not automatically establish furtherance, and an alternative-sentence declaration does not automatically cure every sentencing error.

6. Complex Concepts Simplified

Reasonable suspicion and probable cause

Reasonable suspicion requires a specific, objective basis for suspecting unlawful activity. Probable cause is stronger: the known circumstances reasonably indicate that an offense occurred. The credited traffic observation met the higher threshold here.

Fruit of the poisonous tree

Evidence derived from an unlawful governmental act may be excluded. Kendrick’s argument failed at its starting point because the court held that the stop was lawful.

Plain view

Officers may seize qualifying evidence visible from a lawful position when the doctrine’s requirements, including lawful access, are satisfied. The court applied it to the bag outside the vehicle.

Knowing, intelligent, and voluntary waiver

A person must understand the relevant rights and choose to surrender them without coercion. A signature is strong evidence, but the surrounding circumstances still matter.

Constructive possession

A person may possess an item without holding it, through knowing control or the ability and intention to exercise control. Mere proximity is not itself the complete inquiry.

“In furtherance” and nexus

The firearm must have a meaningful connection to advancing the trafficking crime, not merely be present at the same time.

Concurrent and consecutive sentences

Concurrent sentences run together; consecutive sentences run one after another. Kendrick’s two 84-month terms ran together, followed by 60 additional months.

Upward variance

A sentence above the advisory Guidelines range, justified by statutory sentencing considerations. The panel assessed Kendrick’s sentence as an upward variance under his preferred calculation.

Substantive reasonableness

Whether the sentence’s length is defensible in light of the offense, the offender, and statutory sentencing purposes—not merely whether the calculation process was correct.

7. Conclusion

United States v. Michael Kendrick affirms established boundaries rather than creating a new binding rule. Credited observation justified the stop; an informed waiver permitted questioning; cumulative evidence supported the convictions; and a neutral factor-based instruction properly clarified the firearm–drug nexus.

Its central sentencing lesson is equally precise: an unresolved Guidelines dispute need not require reversal when the judge would impose the same sentence and that sentence remains reasonable under the defendant’s preferred range. The opinion does not, however, decide whether Kendrick’s prior conviction supported the disputed enhancement.
