Ends-of-Justice Continuances May Await Imminent En Banc Guidance When Reasons Are Clear from the Record — United States v. Willie David Lark (6th Cir. 2026)

I. Introduction

In United States v. Willie David Lark, the Sixth Circuit affirmed drug-trafficking convictions after the defendant challenged (1) three warrants (two vehicle-tracking warrants and a residential search warrant) under the Fourth Amendment, (2) the denial of a Franks hearing, and (3) the denial of dismissal under the Speedy Trial Act.

The investigation began after Lark twice sold cocaine to a confidential informant in controlled buys in Benton Harbor, Michigan. Police sought and obtained warrants to place a tracking device on the red pickup truck Lark used during the transactions, later renewed tracking based on additional informant information and corroboration, and ultimately obtained a warrant to search Lark’s South Fair Avenue residence. The search yielded multiple controlled substances and documents tying Lark to the home.

The appeal presented three recurring federal-criminal-procedure issues: (1) what facts suffice to establish probable cause for vehicle-tracking and residence-search warrants (including informant reliability and staleness), (2) what qualifies as a “substantial preliminary showing” to merit a Franks v. Delaware hearing based on allegedly inconsistent affidavits or alleged omissions, and (3) whether an “ends-of-justice” continuance under the Speedy Trial Act may be justified by awaiting imminent en banc guidance, and how explicitly the district court must place its reasons on the record.

II. Summary of the Opinion

The Sixth Circuit (McKeague, J., joined by Sutton, C.J., and Bush, J.) affirmed across the board:

  • Probable cause supported both vehicle-tracking warrants because the affidavits tied the red pickup truck to two controlled buys and later to repeated alleged deliveries, corroborated by tracking data and surveillance.
  • Probable cause supported the residence-search warrant because the affidavit established a sufficient nexus between South Fair Avenue and drug trafficking—most notably a recent purchase by a reliable informant at that location, combined with other informant tips, tracking evidence, and surveillance.
  • The district court did not abuse its discretion in denying a Franks hearing because Lark did not make the required substantial preliminary showing of a knowing, intentional, or reckless falsehood (or an omission made with intent to mislead) that was material to probable cause.
  • The district court properly denied dismissal under the Speedy Trial Act; an ends-of-justice exclusion was supported by the record where the district court delayed proceedings to await en banc guidance in United States v. Sanders and explained its rationale by the time it ruled on the motion to dismiss.

III. Analysis

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

1. Probable Cause Framework: Totality, Deference, and the “Low Bar”

The court grounded its Fourth Amendment analysis in the familiar “totality of the circumstances” framework of Illinois v. Gates, 462 U.S. 213 (1983), quoted via United States v. White, 990 F.3d 488 (6th Cir. 2021). That matters because it directs courts away from rigid checklists and toward a practical probability assessment.

The opinion reinforced deference to the issuing judge by citing United States v. Moore, 999 F.3d 993 (6th Cir. 2021), emphasizing that review is confined to the affidavit’s “four corners” and that probable cause is a “low bar.” This posture underwrote the court’s unwillingness to disassemble the affidavits into isolated deficiencies.

2. Vehicle Tracking Warrants

For tracking devices, the court relied on United States v. Coleman, 923 F.3d 450 (6th Cir. 2019) for the standard: probable cause exists if the affidavit supports a fair probability that the device will uncover evidence, fruits, or instrumentalities of a crime.

The panel treated the two controlled buys—paired with Lark’s consistent use of the same red pickup—as independently weighty evidence under Coleman, also citing United States v. Easter, No. 25-1248, 2026 WL 18812 (6th Cir. Jan. 2, 2026) to underscore that tracking can be justified where it could reasonably uncover further evidence of wrongdoing.

3. Nexus to a Residence and Informant-Based Probable Cause

The key question for the residence warrant was the “nexus” between the home and evidence sought, framed through United States v. Sanders, 106 F.4th 455 (6th Cir. 2024) (en banc) and United States v. Crawford, 943 F.3d 297 (6th Cir. 2019). Sanders provided the formulation that officers must supply direct or circumstantial support creating more than mere suspicion; Crawford supplied the articulation of a required “nexus.”

On informant reliability, the court’s reasoning tracked several Sixth Circuit informant cases:

  • United States v. Greene, 250 F.3d 471 (6th Cir. 2001): an affiant generally need only specify that the confidential informant gave accurate information in the past.
  • United States v. Allen, 211 F.3d 970 (6th Cir. 2000) (en banc): statements that an informant is credible based on a multi-year relationship and prior reliable tips can suffice.
  • United States v. Jackson, 470 F.3d 299 (6th Cir. 2006): anonymity of a confidential informant is not fatal.

Additionally, the court supported the use of corroboration—especially tracking data and controlled buys—by citing United Staes v. Dyer, 580 F.3d 386 (6th Cir. 2009) for the proposition that independent information can augment informant credibility and that criminal history, while not dispositive, is relevant.

The residence nexus was particularly strengthened by two precedents:

  • Untied States v. Moore, 661 F.3d 309 (6th Cir. 2011): a reliable informant’s tip, with a shown basis of knowledge, can establish probable cause that drugs will be found at a residence.
  • United States v. Archibald, 685 F.3d 553 (6th Cir. 2012): a controlled buy connected to a location directly links the place to drug sales.

4. Staleness

The staleness argument was dispatched via United States v. Pinson, 321 F.3d 558 (6th Cir. 2003), which the panel used to justify the common-sense conclusion that drugs may still be found in a residence three days after a purchase there—particularly in the context of ongoing trafficking.

5. Rejecting “Divide-and-Conquer” Attacks

The court cited United States v. Christian, 925 F.3d 305 (6th Cir. 2019) (en banc) to condemn “line-by-line scrutiny” and a “divide-and-conquer” approach. It also cited Allen for the principle that affidavits are evaluated for what they contain, not what they omit.

6. Franks Hearing Standards

The panel anchored the Franks analysis in multiple authorities:

  • Franks v. Delaware, 438 U.S. 154 (1978): requires a substantial preliminary showing of intentional/reckless falsity and materiality to probable cause.
  • United States v. Richards, 164 F.4th 508 (6th Cir. 2026): reiterates the heavy burden and presumption of affidavit validity; also used to reject conclusory “omission” theories.
  • United States v. Young, 847 F.3d 328 (6th Cir. 2017): decision to hold a Franks hearing is within the district court’s sound discretion.
  • United States v. Hammond, 351 F.3d 765 (6th Cir. 2003): invoked as a contrasting example where “remarkable inaccuracies” justified concern.
  • United States v. Higgins, 141 F.4th 811 (6th Cir. 2025), cert. denied, 223 L. Ed. 2d 540 (2026): omissions require an even higher showing—intent to mislead and criticality to probable cause.
  • United States v. McMurtrey, 704 F.3d 502 (7th Cir. 2013): used to validate the district court’s method of comparing affidavits for contradictions in the Franks context.

7. Speedy Trial Act: Ends-of-Justice and Timing of Findings

On the Speedy Trial Act, the panel relied on a line of Supreme Court and Sixth Circuit authority:

  • Zedner v. United States, 547 U.S. 489 (2006): an ends-of-justice continuance must be supported by reasons set forth on the record; reasons need not be contemporaneous but must appear no later than the ruling on the motion to dismiss.
  • United States v. Richardson, 681 F.3d 736 (6th Cir. 2012): adopts the rule that reasons may be placed on the record by the time the court rules on the motion to dismiss.
  • United States v. White, 920 F.3d 1109 (6th Cir. 2019): no “magic words” are required; ends-of-justice reasons may be clear from context/record, and a continuance can qualify even if not labeled as such.
  • United States v. Brown, 100 F.4th 703 (6th Cir. 2024): contrasted as an example where retrospective justification was insufficient—used to show why the record in Lark was different (Sanders’ importance was evident from the beginning).
  • United States v. Patton, 651 F. App'x 423 (6th Cir. 2016): invoked for the idea that where the record shows genuine reasons, “phoney, post-hoc justifications” are not at play.

The opinion also referenced motion-related exclusions and waiver principles:

  • United States v. Mentz, 840 F.2d 315 (6th Cir. 1988): motion-to-hearing time can be excluded under 18 U.S.C. § 3161(h)(1)(D).
  • United States v. Fowler, 819 F.3d 298 (6th Cir. 2016) and United States v. Perry, No. 22-2031, 2024 WL 692890 (6th Cir. Feb. 20, 2024): undeveloped arguments and failure to challenge independent grounds can render review unavailable.

8. Handling a “Fractured Panel” Citation

The court addressed the defendant’s reliance on United States v. Westley, No. 2 2 -3356, 2 02 3 WL 5377894 (6th Cir. 2 02 3), clarifying that despite fracturing, the majority on probable cause found the affidavit sufficient. This served to blunt an attempted analogical attack on the nexus analysis.

B. Legal Reasoning

1. Vehicle Tracking: Controlled Buys + Consistent Vehicle Use = Fair Probability

The panel treated the controlled buys as the backbone of probable cause: the informant was searched, used recorded funds, was surveilled returning to the detective, and produced cocaine. The crucial tie to the tracking device was that Lark arrived at both transactions in the same red pickup truck. Under Coleman, that was enough to believe tracking would reveal evidence of trafficking—such as additional delivery locations, stash sites, or meeting patterns.

The second tracking warrant became stronger, not weaker: Informant 2 alleged repeated deliveries using the red pickup; prior tracking data showed trips consistent with those claims; and surveillance showed the vehicle at places the detective associated with trafficking. The court emphasized that probable cause does not require certainty, only a fair probability that tracking will uncover evidence.

2. Residence Search: A Direct Recent Buy at the House as the “Nexus Anchor”

The court’s nexus reasoning is best understood as layered corroboration with a “center of gravity”:

  • The anchor fact: Informant 4—described as reliable—both observed multiple drugs at South Fair Avenue and purchased heroin from Lark at that property three days before the warrant application.
  • Supporting facts: Informant 1’s second buy began in the driveway; Informant 2’s alleged deliveries often began or ended at South Fair Avenue; tracking data showed short visits to Informant 2’s residence consistent with deliveries; and the detective observed activity at South Fair Avenue consistent with quick drug transactions.
  • Contextual reinforcement: Lark lived there and had a prior controlled-substance delivery conviction, which the court treated as relevant though not dispositive.

This structure allowed the court to answer two frequent defense criticisms. First, even if some details were missing (e.g., the affidavit did not specify precisely where on the property the hand-to-hand transfer occurred), the combination of an on-premises buy and an informant’s direct observations still created a fair probability that contraband would be found at the residence. Second, even if some information pre-dated the warrant, the buy within 72 hours overcame staleness concerns under Pinson.

3. Informant Reliability: Track Record + Corroboration + Multiple Consistent Sources

Lark’s principal attack—that the affidavits used generic assertions of informant reliability—ran into three points the panel found decisive:

  1. Track records were stated: each informant had provided reliable/verified information over substantial periods (months to years), fitting Greene and Allen.
  2. Corroboration existed: tracking data and surveillance aligned with informant claims, and controlled buys provided high-value corroboration.
  3. Consistency across four informants: rather than a single untested source, multiple informants converged on the same core narrative—Lark dealt drugs, used the red pickup, and operated from/through South Fair Avenue.

The panel’s broader methodological move—guided by Christian—was to reject atomized objections that would require each fact to be independently sufficient. Under Gates, the question is whether the whole mosaic supports a fair probability.

4. Franks: Differences in Detail Are Not Contradictions, and Omissions Require Proof of Intent to Mislead

Lark tried to convert differences in how the second controlled buy was described into a falsity claim. The panel’s response drew a line between supplementation and contradiction. The vehicle affidavits said Informant 1 purchased cocaine from Lark and that Lark drove the red pickup; the residence affidavit added that the deal began in the driveway and was later consummated through an intermediary. The court agreed with the district court that these were “different details” but not “contradictory details.”

As to omissions, Higgins imposed the “even higher standard”: intent to mislead and criticality to probable cause. The court found Lark offered only conclusory assertions that a fuller description would have changed the probable cause analysis, which falls short of the “substantial preliminary showing” demanded by Franks and reiterated in Richards.

The tracking-device timing argument met a similar fate. Even assuming a discrepancy, Lark did not show it was intentional or reckless, nor did he show materiality—i.e., that removing the challenged assertion would collapse probable cause.

5. Speedy Trial Act: Awaiting En Banc Guidance as a Legitimate “Ends-of-Justice” Basis, with Reasons Clear from the Record

The panel accepted the district court’s rationale: delaying trial to await the en banc decision in United States v. Sanders, which potentially would “reshape” the nexus analysis central to the suppression litigation. The Sixth Circuit treated this as a legitimate “ends-of-justice” ground and focused the dispute on timing and adequacy of the district court’s explanation.

Under Zedner and Richardson, the district court need not state its reasons at the exact moment it grants the continuance; it must place reasons on the record by the time it rules on a motion to dismiss. Under White, the court need not use “magic words” if the justification is evident from context.

The panel distinguished United States v. Brown by emphasizing that, here, the record showed Sanders was on the court’s mind “from the get-go”: it was the first topic at the suppression hearing, and the trial was continued pending resolution of the suppression motion with Sanders’ potential effect repeatedly referenced. That, in the panel’s view, negated the claim of a post-hoc rationalization.

C. Impact

1. Fourth Amendment Practice: Reinforcing “Mosaic” Probable Cause in Multi-Informant Drug Investigations

Although “NOT RECOMMENDED FOR PUBLICATION,” the decision reflects—and may practically reinforce—several operational lessons for future warrant litigation in the Sixth Circuit:

  • Controlled buys remain a powerful probable-cause engine, even when affidavits do not meticulously describe every moment of surveillance, so long as the informant’s reliability and monitoring steps are described and the narrative is coherent.
  • Multiple informants with track records, providing consistent information over time, can overcome defense claims that reliability statements are too “general,” especially when some tips are corroborated by technology (tracking) and police surveillance.
  • For residences, a recent purchase at the target property is especially potent against staleness and nexus challenges.

2. Franks Litigation: Emphasis on Material Contradictions, Not Added Detail

The opinion signals that defendants will struggle to obtain a Franks hearing by pointing to affidavits that are merely written with different levels of detail for different investigative steps. To convert variance into a Franks issue, the discrepancy must look like a real contradiction or show intentional/reckless falsity, and it must matter to probable cause.

3. Speedy Trial Act: A Practical Template for “Ends-of-Justice” When Waiting for Imminent Appellate Guidance

The Speedy Trial portion may be the most “process-significant” aspect of the case: it endorses the idea that a district court may, consistent with 18 U.S.C. § 3161(h)(7)(A), await imminent and potentially dispositive en banc guidance relevant to a key pretrial motion. It also reiterates that the explanation can be contextual and need not be contemporaneous, as long as it appears on the record by the motion-to-dismiss ruling.

For district courts, the case underscores best practices: repeatedly referencing the pending decision and its relevance in hearings/orders creates the contextual record that White and Zedner demand. For defendants, it highlights the uphill battle of arguing “post-hoc” justification when the docket already reflects contemporaneous concern with the pending appellate guidance.

IV. Complex Concepts Simplified

  • Probable cause: not proof beyond a reasonable doubt; it is a practical judgment that there is a “fair probability” evidence of a crime will be found in a place (or that a method like tracking will uncover evidence).
  • Totality of the circumstances: courts do not require any single fact to prove the case; they consider how facts work together (informants + corroboration + controlled buys + surveillance).
  • Nexus: the connection between the place to be searched (here, a home) and the evidence sought. A recent controlled buy at the home is a strong nexus indicator.
  • Staleness: information supporting a warrant must be timely enough to suggest evidence is still likely present. A drug buy three days before the warrant commonly defeats staleness arguments.
  • Franks hearing: a special evidentiary hearing where the defendant challenges truthfulness of a warrant affidavit. It requires a substantial preliminary showing of intentional/reckless falsity (or an omission intended to mislead) and that the misstatement/omission mattered to probable cause.
  • Speedy Trial Act “ends-of-justice” continuance: a statutory pause of the speedy-trial clock when the judge finds that a delay serves justice more than immediate trial does. Reasons must be on the record, but not necessarily stated at the same moment the continuance is granted if the record later makes them clear in time.

V. Conclusion

United States v. Willie David Lark affirms a trio of rulings that commonly arise in drug prosecutions: (1) probable cause for tracking and residence warrants can rest on controlled buys, consistent multi-informant reporting, and corroboration by tracking/surveillance; (2) Franks hearings are reserved for substantial, material showings of intentional/reckless falsehood or intentionally misleading omissions—not mere differences in affidavit detail; and (3) an ends-of-justice continuance under the Speedy Trial Act may be supported by awaiting imminent en banc guidance, with adequate reasons supplied by the time the court rules on a motion to dismiss and where the rationale is clear from the record’s context.
