Residential Search Warrants Require a Current, Particularized Nexus—Area Drug Activity and Stale Home Facts Defeat Probable Cause and Can Defeat Leon Good Faith

United States v. Earl Griffin, Jr. is a Fourth Amendment decision about the minimum constitutional showing needed to search a home for drug evidence. The Calvert County Sheriff’s Office Drug Enforcement Unit sought a no-knock warrant to search a residence at 6740 N. Solomons Island Road in an area known as “Kent Bottom,” described in the affidavit as a long-running “open-air drug market.” The affidavit mixed (i) broad, area-wide allegations about drug dealing in Kent Bottom over decades, (ii) older incidents (including a 2006 search of the residence), and (iii) more recent surveillance describing suspected outdoor transactions near multiple nearby properties.

Officers executed the warrant on September 5, 2019. No drugs were found inside the home, but drugs and a firearm were recovered from a Chevrolet Tahoe parked beside the residence. Griffin was ultimately convicted only of being a felon in possession of a firearm.

The central issues on appeal were (1) whether the affidavit established probable cause to search the residence—specifically, whether it satisfied the Fourth Circuit’s requirements of nexus (connection to the particular home) and timing (non-staleness), and (2) if not, whether suppression was nonetheless barred by the good-faith exception of United States v. Leon.

The majority held the warrant was unsupported by probable cause because the affidavit’s key facts were either: (a) not connected to the residence to be searched, (b) too old (stale), or (c) both. The affidavit’s only concrete allegation of drug activity inside the home was a 2006 incident—thirteen years before the warrant. More recent information described outdoor activity in Kent Bottom, including a single street-level sale attributed to Griffin’s son outside the residence months earlier and observations of Griffin’s brother walking in and out of the home around suspected outdoor activity. The court concluded that these facts did not create a “fair probability” that evidence of drug crime would be found inside the home at the time of the search.

The court further held that Leon good faith did not apply because the affidavit was “so lacking in indicia of probable cause” that reliance was objectively unreasonable given the conspicuous absence of a current, residence-specific link and the evident staleness of the only inside-the-home incident.

Remedy: the Fourth Circuit reversed the denial of suppression, vacated Griffin’s conviction, and remanded.

The opinion distills two “basic requirements” for residential search warrants: (1) nexus—the affidavit must connect the evidence sought to the particular place to be searched; and (2) timing—the affidavit must show the evidence is likely to be there when the search occurs. Area-wide suspicion and a neighborhood’s reputation cannot substitute for place-specific facts, and “ordinary movement around a family home” cannot supply the missing nexus.

• Riley v. California and Carpenter v. United States (quoting Boyd v. United States): cited to frame the Fourth Amendment’s purpose—preventing arbitrary rummaging and “too permeating police surveillance.” This sets the tone for demanding rigor before authorizing residential intrusion.
• Florida v. Jardines: used for the maxim that “the home is first among equals,” strengthening the requirement that warrants crossing the home’s threshold must be tightly justified.
• Payton v. New York (quoting United States v. U.S. Dist. Ct. for E. Dist. of Mich., S. Div.): anchors the “firm line at the entrance of the house” and the characterization of home entry as the “chief evil.” The majority leverages this to reject “suspicion by geography.”
• Lange v. California and Kentucky v. King: confirm that warrant-based home entry is permissible only with a “proper warrant,” i.e., one supported by probable cause.
• Brinegar v. United States: invoked to emphasize probable cause as protection against “whim or caprice,” a theme the court returns to when rejecting Kent Bottom’s reputation as a proxy for individualized residential probable cause.

• Illinois v. Gates (and Spinelli v. United States): supplies the totality-of-the-circumstances test and deference to the issuing judge, but the majority stresses deference is not license to accept “improbable leaps.”
• Chatrie v. United States (U.S. June 29, 2026): cited for the principle that where a warrant exists, legality turns on whether a magistrate “properly found probable cause.” The majority uses this to keep the analysis focused on the affidavit’s showing—not post hoc rationalizations.
• United States v. Lyles: provides the Fourth Circuit’s modern articulation of (i) “substantial basis” review and (ii) the importance of timing and nexus for homes. Lyles becomes the majority’s comparator both on probable cause and on why good faith fails when the affidavit is too thin.

• Zurcher v. Stanford Daily: cited for the requirement that the affidavit connect evidence to the place searched.
• United States v. Orozco: quoted for the Fourth Circuit’s statement that there must be “some nexus between the suspected crime and the place to be searched.”
• United States v. Grossman: used to show nexus can be proven by direct observations or reasonable inferences from circumstances; the majority accepts inference as permissible in principle, then finds the inferences demanded here cross the line.
• Ybarra v. Illinois (citing Sibron v. New York): central to the majority’s rejection of “mere propinquity” reasoning—being near suspected drug activity does not automatically justify searching a person (and, by extension in this opinion’s logic, does not justify searching a home) without particularized facts.
• Out-of-circuit and state cases—United States v. Hodge, United States v. Sumlin, United States v. Coleman, United States v. Ellison, Commonwealth v. Tapia, United States v. Burton: cited as examples of additional residence-linked facts that can make the inference reasonable (dealer lives there, leaves home to sell, returns after sale, retrieves drugs from home, carries proceeds/drugs into home). The majority’s key move is comparative: none of these residence-anchoring facts appeared in Griffin’s affidavit.

• Maryland v. Pringle: cited to emphasize probable cause involves probability that evidence is in a particular place, not just “somewhere.”
• United States v. Chatrie (4th Cir. 2025) (Berner, J., concurring), vacated and remanded: used by analogy—government can’t search every unit of an apartment building based on generalized belief evidence is somewhere in the building; similarly, it can’t pick one Kent Bottom home without facts making that home the probable repository.
• Maryland v. Garrison: supports the proposition that the Fourth Amendment’s place specificity matters when multiple distinct places exist.

• United States v. McCall (quoting Sgro v. United States): provides the staleness standard—probable cause must rest on facts close enough to issuance to justify belief evidence is there “at that time,” assessed pragmatically by activity type and evidence type.
• United States v. Raymonda: supports the idea that isolated older incidents do not justify belief evidence remains months later absent continuing activity.
• United States v. Lyles: again used to show why a single incident, especially without temporal cues indicating ongoing activity, weakens the “evidence will be there now” inference.

• United States v. Valenzuela: quoted for the warning that totality review cannot be satisfied by “piling hunch upon hunch.” The majority uses this to reject the government’s attempt to aggregate stale facts + neighborhood reputation + ambiguous behavior into a residential search justification.
• Alabama v. White and United States v. Drakeford: deployed in a footnote to illustrate that even “reasonable suspicion” requires articulable facts and not mere conclusory “I know it when I see it” assertions; the majority uses this as a rhetorical benchmark to highlight just how thin the affidavit was.
• United States v. Hawkins: cited to note that even for reasonable suspicion, presence in a high-crime area is a weak factor—reinforcing that a home search requires far more than Kent Bottom’s reputation.

• United States v. Leon: supplies the four scenarios where reliance is not objectively reasonable; the majority applies the third (“so lacking in indicia of probable cause”).
• United States v. Perez and United States v. Bynum: provide the Fourth Circuit formulation of objective reasonableness and clarify the “so lacking” test is less demanding than “substantial basis,” but not toothless.
• United States v. Doyle: used to show that timing failures can be so glaring that good faith is unavailable; in Griffin, the dates themselves showed the inside-the-home incident was thirteen years old and the more recent outdoor sale was isolated.
• United States v. Cordova: relied on for the principle that the good-faith exception is “broad” but “not boundless”; sparse, attenuated links to a home can reduce the warrant to “nothing more than a hunch,” defeating good faith. The majority deems Griffin even weaker than Cordova.
• The opinion also clarifies (in a lengthy footnote) how much weight to give judicial approvals in good-faith analysis, citing United States v. DeQuasie, United States v. Smith, and Ornelas v. United States: appellate review of good faith is de novo; the issuing judge’s approval cannot “by itself” supply missing indicia of probable cause without becoming circular; and a district court’s agreement is not entitled to deference in the good-faith determination.

• United States v. Patterson: cited for the rule that a premises warrant extends to vehicles on the property reasonably appearing under dominion/control associated with the premises.
• Collins v. Virginia: invoked to emphasize that a vehicle within curtilage does not lose Fourth Amendment protection simply because it is a car—supporting the court’s treatment of the Tahoe search as tied to the (invalid) premises search authorization.

(1) Nexus failure. The affidavit described a geographic area with multiple residences and recurring outdoor drug activity, but did not provide facts indicating that evidence—drugs, money, packaging, records, firearms—would likely be found inside 6740. The majority treats as constitutionally significant what the affidavit did not say: no observation of contraband entering/leaving the home; no statement that a dealer lived there; no controlled buys tied to the interior; no trash pulls; no post-transaction returns to the residence; and no recovered drugs tied to the residence’s occupants via residence-linked conduct.

The opinion’s “improbable leap” analysis is the doctrinal fulcrum. It acknowledges that courts may infer that dealers keep evidence at home, but holds that inference becomes unreasonable when the affidavit offers only proximity, reputation, and ambiguous movements—particularly where the affidavit itself identifies several other plausible locations (other residences and properties) associated with suspected dealers.

(2) Timing (staleness) failure. The only direct inside-the-home incident occurred in 2006. The majority characterizes it as isolated historical conduct without evidence of ongoing interior use of the home for trafficking. The later 2019 street-level transaction attributed to Griffin’s son happened outside, four months earlier, and was not tied to entry into or use of the house. The warrant therefore lacked facts supporting the proposition that evidence would be in the home at issuance/execution.

(3) Totality does not cure missing elements. The majority explicitly rejects the idea that combining weak, stale, and non-particularized facts can manufacture probable cause; doing so would effectively replace the particularized probable-cause requirement with “suspicion by geography.”

Even after finding no probable cause, the majority takes the more defendant-protective step of denying good faith. The reasoning is comparative and practical: in United States v. Lyles, officers had fresh, place-specific physical evidence (a trash pull with marijuana remnants) and still could not invoke good faith because the showing was too flimsy to justify rummaging through a home. In Griffin, there was not even comparable fresh, residence-tethered evidence.

The staleness problem is also framed as obvious on the face of the affidavit (as in United States v. Doyle): dates revealed the interior-home evidence was thirteen years old and that recent conduct was isolated and outdoors. Under the majority’s approach, when an affidavit’s own chronology makes the defect apparent, reliance becomes “entirely unreasonable.”

The opinion’s footnote addressing the dissent is itself an important doctrinal clarification: the court warns against making good-faith review circular by treating issuance of the warrant (or a later district-court agreement) as effectively dispositive of objective reasonableness.

The dissent would affirm based on good faith, emphasizing Leon’s statement that warrant-backed searches “will rarely” require deep reasonableness inquiry and that suppression is appropriate only where officers had “no reasonable grounds” to believe the warrant properly issued. It also stresses that both the state issuing judge and the federal district judge found probable cause, arguing that fact supports the reasonableness of officer reliance.

The majority answers directly: judicial approval can matter in close cases, but cannot substitute for missing indicia of probable cause, and district-court agreement is not entitled to deference in de novo good-faith review.

• Higher demands for residence-specific facts in “open-air market” cases. Investigations describing a neighborhood as an “open-air drug market” must still identify why a particular residence is the likely repository of evidence. Expect future affidavits to add concrete residence-linking details (controlled buys tied to the residence, observed entry/exit patterns linked to transactions, trash pulls, informant reliability statements tied to the home, surveillance of objects moving into the residence).
• Staleness scrutiny sharpened for homes. The decision reinforces that a single old interior-home incident (even if serious) cannot justify a present-day home search absent evidence of ongoing interior use or reasons to believe the specific evidence persists.
• Narrower operational space for Leon in thin-home-nexus warrants. The court’s denial of good faith signals that officers in the Fourth Circuit may not safely rely on warrants built from neighborhood reputation plus ambiguous conduct, especially when the affidavit’s dates reveal staleness.
• Methodological guidance for good-faith review. The opinion’s discussion of how (not) to weigh the issuing judge’s and district court’s decisions may influence suppression litigation by focusing courts on the affidavit’s contents rather than institutional agreement.

• Probable cause: not certainty, but a fair, common-sense probability that evidence of a crime will be found in the specific place being searched.
• Nexus: the “why here?” requirement—facts must connect the suspected evidence to the particular home (not just to the neighborhood).
• Staleness (timing): the “why now?” requirement—older facts lose force unless the affidavit shows ongoing activity or explains why the type of evidence would still be present.
• Totality of the circumstances: courts consider all facts together, but cannot create probable cause by stacking weak assumptions (“hunch upon hunch”).
• Leon good-faith exception: even if the warrant is invalid, evidence may be admitted if officers reasonably relied on it—but not when the affidavit is so deficient that a trained officer should have recognized the absence of probable cause.
• Curtilage: the area immediately around a home (like a side yard/drive area) that receives strong Fourth Amendment protection; a car parked there is not automatically less protected.

United States v. Earl Griffin, Jr. reinforces a stringent, home-protective application of the Fourth Amendment: a residential search warrant must supply both a current, non-stale basis to believe evidence exists and a particularized nexus tying that evidence to the specific home. Broad descriptions of neighborhood drug activity, stale interior-home incidents, and ambiguous association-based observations cannot be combined to cross the “firm line” at the home’s entrance. The decision’s additional significance lies in its refusal to apply Leon good faith where the affidavit’s missing nexus and evident staleness made reliance objectively unreasonable, and in its caution against treating judicial approval as a substitute for the affidavit’s own indicia of probable cause.
