Controlled-Buy Affidavits Trigger Leon Good-Faith; Deceptive Miranda-Form Signatures Do Not End the Waiver Inquiry

1. Introduction

Case: United States v. Weaver, No. 25-60269 (5th Cir. Apr. 2, 2026).
Parties: United States (Plaintiff–Appellant) vs. Lexus Sanchez Weaver (Defendant–Appellee).
Posture: Government appeal from a suppression order entered by the Northern District of Mississippi.

Law enforcement obtained a search warrant for Weaver’s home based on an affidavit describing three controlled buys using a confidential informant (“CI”) under continuous surveillance. The warrant was approved via FaceTime by a municipal judge operating under a still-effective Mississippi Supreme Court emergency order allowing videoconference approvals. Officers searched the home and recovered drugs, firearms, money, and phones. Weaver was then interviewed; an officer read the Miranda warnings and obtained Weaver’s signature on a form, but the officer framed the signature as an acknowledgment that rights were read, while the form also contained an un-read “Waiver of Rights” paragraph.

The district court suppressed (1) the physical evidence from the search warrant and (2) Weaver’s interview statements. The Fifth Circuit reversed and remanded, holding the good-faith exception applied to the warrant and directing the district court to evaluate whether Weaver implicitly waived Miranda despite an invalid express waiver.

2. Summary of the Opinion

  • Search evidence: The Fifth Circuit held the affidavit was not “bare bones” and officers’ reliance on the warrant was objectively reasonable under the good-faith exception. Because good faith applied, the court did not reach probable cause.
  • Statements: The Fifth Circuit agreed the signature-based “express waiver” was obtained deceptively and therefore was not voluntary. But the court held the analysis does not stop there: a suspect may still implicitly waive Miranda rights through conduct after receiving and understanding warnings. The district court erred by not conducting an implied-waiver analysis.
  • Remand: The case was remanded for the district court to decide implied waiver under the totality of circumstances; the panel retained jurisdiction pending that decision.

3. Analysis

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

A. Appellate review framework

  • United States v. Norman, 129 F.4th 874, 876 (5th Cir. 2025) (citing United States v. Cavazos, 288 F.3d 706, 709 (5th Cir. 2002)): The court applied clear-error review for facts and de novo review for legal conclusions. This set the stage for the Fifth Circuit to reassess—without deference—the legal sufficiency of the good-faith determination and the Miranda-waiver principles applied.

B. Search warrants and the good-faith exception

  • United States v. Payne, 341 F.3d 393, 399 (5th Cir. 2003): Provided the two-step suppression framework: (1) good faith, then (2) probable cause, with probable cause generally unnecessary if good faith applies unless a novel, guidance-worthy question is presented. The court followed this script and ended the warrant analysis at good faith.
  • United States v. Leon, 468 U.S. 897, 921-25, 104 S. Ct. 3405, 3419-22 (1984): The foundational doctrine: evidence may be admitted when officers reasonably rely on a warrant later found deficient. The court used Leon both to justify application of good faith and (via the opinion’s footnote) to reject “penalizing the officer for the magistrate’s error.”
  • United States v. Morton, 46 F.4th 331, 336 (5th Cir. 2022) (en banc): Supplied the four circumstances where reliance is unreasonable, focusing the dispute on the third: whether the affidavit was so lacking in probable cause as to be “bare bones.” Morton also contributed a key comparative method: affidavits are assessed in context, and if not “wholly conclusory,” good faith usually applies.
  • United States v. Norman, 129 F.4th at 876: Defined “bare bones” affidavits as “wholly conclusory,” lacking facts allowing independent probable-cause evaluation. The court used Norman both as a definition and as a comparator (an affidavit with concrete communications/transaction details supported good faith).
  • United States v. Broussard, 80 F.3d 1025, 1034 (5th Cir. 1996): Addressed the district court’s critique of “boilerplate” language. Broussard holds that boilerplate does not defeat good faith when the affidavit contains “more.” The Fifth Circuit invoked this to reject suppression premised on generalized phrasing.
  • Waltman v. Payne, 535 F.3d 342, 347-48 (5th Cir. 2008) and United States v. Delacruz, 452 F. App'x 461, 462 (5th Cir. 2011): These cases undermined the district court’s insistence on drug “authentication” (e.g., field testing) as a minimum requirement. The Fifth Circuit treated the lack of testing as a best-practice issue, not a constitutional floor that makes reliance unreasonable.
  • United States v. Pena-Rodriguez, 110 F.3d 1120, 1131 (5th Cir. 1997) and United States v. Mays, 466 F.3d 335, 344 (5th Cir. 2006): Both reinforce that an informant tip, corroborated by law-enforcement investigation (including surveillance and controlled buys), can support a reasonable belief in probable cause. The court used these to reframe the affidavit as based on corroborated controlled-buy evidence, not mere CI say-so.
  • United States v. Barrington, 806 F.2d 529, 531 (5th Cir. 1986) and Spencer v. Staton, 489 F.3d 658, 661-62 (5th Cir. 2007), withdrawn in part on reh'g (July 26, 2007): These were negative exemplars—affidavits that are truly bare bones. By contrasting the controlled-buy details here with the conclusory affidavits in Barrington and Spencer, the court located this case comfortably on the “not bare bones” side of the line.
  • United States v. Cavazos, 288 F.3d 706, 709 (5th Cir. 2002) (quoted via United States v. Norman, 129 F.4th at 877) and United States v. Morton, 46 F.4th at 339: These supported the court’s “stop at good faith” approach: once good faith applies, the court need not decide whether probable cause actually existed.

C. Miranda waivers (express vs implied) and voluntariness

  • United States v. Cardenas, 410 F.3d 287, 292-93 (5th Cir. 2005): Provided the two-dimensional test for a valid waiver—(1) voluntary choice and (2) full awareness of the right and consequences—evaluated under the totality of circumstances. The Fifth Circuit used this framework to assess the signature-based “waiver.”
  • United States v. Alvarado-Palacio, 951 F.3d 337, 341 (5th Cir. 2020) (quoting Soffar v. Cockrell, 300 F.3d 588, 596 (5th Cir. 2002)): These cases define when deception matters: trickery is prohibited only if it deprives a suspect of essential knowledge to understand rights and consequences. The Fifth Circuit applied this principle to deem the express waiver involuntary because the officer’s presentation of the signature as mere acknowledgment obscured the legal significance of the “waiver” portion.
  • Berghuis v. Thompkins, 560 U.S. 370, 383-84, 130 S. Ct. 2250, 2261-62 (2010) (quoting North Carolina v. Butler, 441 U.S. 369, 373, 99 S. Ct. 1755, 1757 (1979)): These cases supply the central doctrinal move of the opinion. Even without a valid express waiver, Miranda rights can be waived implicitly through silence/understanding plus a course of conduct indicating waiver; uncoerced statements after understood warnings can establish implied waiver. The Fifth Circuit relied on these authorities to hold the district court erred by ending the analysis after finding the signature-based waiver defective.
  • Moran v. Burbine, 475 U.S. 412, 423, 106 S. Ct. 1135, 1142 (1986): Used to emphasize that the officer’s subjective intent (e.g., “I didn’t mean to deceive”) is irrelevant; the focus is on the suspect’s election and the objective circumstances affecting voluntariness/intelligence.

3.2. Legal Reasoning

A. The search warrant: why good faith applied

The Fifth Circuit treated the warrant question as a classic Leon/Payne inquiry: whether the affidavit was so deficient that reliance was unreasonable. It held reliance was reasonable because the affidavit recounted operational details of three controlled buys—dates/timeframes, the residence address, crack cocaine as the purchased drug, pre- and post-buy searches of the CI, continuous surveillance, and additional contextual details (a conversation involving a named third party and the make/model of Weaver’s vehicle).

The district court’s criticisms—boilerplate phrasing, lack of drug testing, and asserted failure to establish CI reliability—did not, in the Fifth Circuit’s view, reduce the affidavit to “wholly conclusory” assertions. Most importantly, the court reframed the affidavit as grounded in corroborated police work (controlled buys plus surveillance), not merely an informant’s unsupported claim. Having found good faith, the court ended the Fourth Amendment analysis without deciding probable cause.

In a notable aside, the Fifth Circuit rebuked the district court’s disapproval of the FaceTime warrant procedure, emphasizing that (1) the judge acted under a still-effective state emergency order, and (2) even if the judge did not administer an oath, suppressing evidence to “penalize” officer conduct for a magistrate’s error is inconsistent with Leon’s deterrence rationale.

B. The interrogation: why the express waiver failed but the inquiry continues

The court accepted that the signature-based express waiver was not voluntary because the officer presented the signature as an acknowledgment that warnings were read, while the form also purported to memorialize a waiver that the officer did not read aloud and the suspect did not appear to read. That mismatch constituted deception relevant to voluntariness under the totality of the circumstances.

But the opinion’s key doctrinal holding is that an invalid express waiver does not resolve admissibility: under Berghuis v. Thompkins and North Carolina v. Butler, a suspect can still waive Miranda implicitly through understanding the warnings and then making uncoerced statements. Because the district court did not undertake this implied-waiver analysis, the Fifth Circuit remanded for a fact-intensive determination (and retained jurisdiction).

3.3. Impact

A. Fourth Amendment / warrant practice

  • Controlled buys + surveillance remain strong “anti–bare bones” facts for good-faith purposes in the Fifth Circuit. Even if an affidavit uses standardized language, the presence of operational details (searches of CI, continuous surveillance, multiple buys, location specificity) will often suffice to make reliance reasonable.
  • Drug field-testing is not a constitutional minimum for warrant affidavits or good-faith reliance, at least where officers have relevant experience and other corroborating indicators exist.
  • Remote/videoconference warrant approval receives a measure of practical tolerance when authorized by governing state court orders; suppression is disfavored when the asserted defect is judicial procedure rather than officer misconduct tied to Fourth Amendment deterrence goals.

B. Fifth Amendment / Miranda administration

  • The decision sends a clear warning that presenting a waiver signature as mere acknowledgment can undermine an express waiver as involuntary.
  • At the same time, it strengthens the government’s fallback position: even when an express waiver is defective, courts must still consider whether the suspect implicitly waived by speaking after understanding the warnings and absent coercion.
  • Litigation-wise, the remand underscores that waiver disputes are likely to turn on video evidence, sequencing of warnings/questions, and the suspect’s demeanor, comprehension, and freedom from coercive tactics.

4. Complex Concepts Simplified

  • Exclusionary rule: A judge-made remedy that can suppress evidence obtained in violation of the Fourth Amendment.
  • Good-faith exception (United States v. Leon): Even if a warrant is later found defective, evidence is usually admissible if officers reasonably relied on the warrant.
  • “Bare bones” affidavit: An affidavit so conclusory that it gives the magistrate no real facts to evaluate—e.g., “an informant says drugs are there,” with no meaningful detail or corroboration.
  • Controlled buy: A structured undercover purchase using an informant, typically involving searches before/after and police surveillance to reduce the chance the drugs came from somewhere else.
  • Miranda warnings: Advisements required before custodial interrogation to protect the privilege against self-incrimination.
  • Express vs. implied waiver: Express waiver is a clear statement/signature waiving rights; implied waiver can arise when a person understands the warnings and then voluntarily chooses to speak.
  • Voluntary vs. knowing/intelligent: “Voluntary” focuses on the absence of coercion or deception undermining free choice; “knowing/intelligent” focuses on comprehension of the rights and consequences.

5. Conclusion

United States v. Weaver clarifies two practical rules for Fifth Circuit suppression litigation. First, where an affidavit recounts multiple controlled buys with surveillance and operational detail, it is unlikely to be deemed “bare bones,” and the Leon good-faith exception will typically foreclose suppression without reaching probable cause. Second, a defective or deceptively obtained express Miranda waiver does not end the inquiry; courts must still assess whether the suspect implicitly waived Miranda under the totality of circumstances after receiving and understanding warnings. The opinion thus both reinforces the durability of good faith in controlled-buy cases and sharpens the analytical discipline required in Miranda-waiver disputes.
