Juan Zayas-Diaz (“Zayas”) challenges two pivotal rulings underlying the district court’s refusal to suppress evidence seized pursuant to a warrant allegedly based on information that failed to connect Zayas to the search premises within a reasonably recent time frame. The court first determined, on the merits, that the affidavit supporting the warrant application contained adequate reliable information to connect Zayas to the search premises in the past. Next, the court bypassed the merits of the staleness claim and held the exclusionary rule inapplicable on the ground that the search had been conducted in “objectively reasonable” reliаnce on the warrant.
See United States v. Leon,
I
BACKGROUND
A. The Graffam Affidavit
On March 8, 1994, a warrant was obtained to search a single-family residence in Bed- *108 ford, New Hampshire, based on a nineteen-page affidavit by Special Agent Gerald Graf-fam of the United States Drug Enforcement Administration (“DEA”), purporting to establish probable cause to believe that Zayas then or recently resided at 16 Holbrook Road and used it as an operational base for cocaine trafficking. 1 The warrant application sought authorization to search for various drug-related documents and currency evidencing the suspected cocaine trafficking activity.
1. The Cocaine Trafficking
The Graffam affidavit included information рurporting to establish that Zayas was supplying cocaine for distribution at various establishments in nearby Manchester, New Hampshire, including the Oasis Social Club. Based on information provided by a “reliable” confidential informant (“first Cl”), the affidavit related that Marcello Sosa had been arrested on January 26, 1994, for selling cocaine at the Oasis Social Club. 2 An arresting officer advised that he had noticed an individual, known to him as “Juan Rosario” alias “Nelson Martell,” at the Oasis Social Club during Sosa’s arrest. The first Cl confirmed that he too had seen Sosa and a person known to him as “Juan” meet at the club, not only at the time of Sosa’s arrest but on prior occasions. Sosa himself admitted that a man named “Juan,” who was present when Sosa was arrested, had supplied the six ounces of cocaine seized from Sosa’s residence shortly after the arrest.
A subsequent documentation and record check disclosed a series of roughly compatible descriptions for “Nelson Martell” (height 5’6-9”; weight 130-160 pounds; hair black or brown; eyes brown; glasses; left-arm tattoo; social security number 001-64 — 1999; birth date either May 4, 1961 or August 16, 1954); home address 275 Lake Avenue, Manchester; license suspension for drunk driving in 1991; New Hampshire conviction and suspended sentence for heroin trafficking in 1992; and a December 1992 arrest and pending prosecution for cocaine trafficking in Connecticut, during which arrest Zayas attempted tо discard cocaine over a highway embankment; and other aliases, including “Juan Gonzalez.”
On February 24, 1994, twelve days before the search, the Manchester police interviewed a confidential informant (“second Cl”). The second Cl, who had “provided reliable information to law enforcement in the past,” advised that he knew a person named “Juan,” surname believed to be “Es-quevar,” who “currently controls” cocaine distribution at various Manchester business establishments, including the Oasis Social Club, and who delivered cocaine daily to his “workers,” including Sosa. The second Cl described “Juan” (Cuban, dark-skinned, height 5T0”, weight 160 pounds, black hair, brown eyes, glasses), and told the authorities that he was “aware” thаt “Juan” had been arrested in Connecticut on a cocaine trafficking charge, and that “Juan” had attempted to discard two kilos of cocaine at the time of the arrest by throwing it over a highway embankment.
2. Zayas and 16 Holbrook Road
Although the documentation check revealed a listed home address for “Nelson Martell” (i.e., Zayas) at 275 Lake Avenue in Manchester, the Graffam affidavit attested to facts purporting to show that Zayas currently or recently resided at 16 Holbrook Road in Bedford, New Hampshire. Following his arrest, Sosa told police that “Juan,” his supplier, “lived” in Bedford, New Hampshire. Moreover, on February 24, 1994, the second Cl also had advised the authorities that Juan “lives” in Bedford and “deals” large amounts of cocaine. The second Cl added that he had “been to Juan’s Bedford residence on several Occasions and seen large quantities of cocaine and cash present,” and that “[S]panish males,” in two or more automobiles bearing New York license plates, arrived “every Tuesday” at the Bedford residence.
On February 24, 1994, after his interview, the second Cl led the authorities to the Bedford premises at which he had visited *109 “Juan.” Presumably to avoid detection, the authorities did not enter upon the premises. Instead, the second Cl described specific features of the residential grounds, including (1) a long driveway lined with three birdhouses containing concealed video camеras; (2) a shack-like residence with peeling brown paint; (3) five dogs outside the house, and an unspecified number of dog houses; and (4) four or five abandoned/junk vehicles, including a motorcycle. The second Cl described interior features of the residence itself, including (1) a video monitor connected to the “birdhouse” cameras; (2) furnishings, “in good condition” compared with the shabby exterior of the residence; and (8) in the basement, a restaurant-style refrigerator for storing cocaine. Subsequent aerial surveillance at 16 Holbrook Road revealed a long driveway, a brown single-family dwelling with detached garage and shed, and “at least three (3) doghouses and two (2) abandoned vehicles.”
3.The “Residence” at 16 Holbrook Road and the Zayas-Koehler “Relationship ”
The Graffam affidavit purported to establish 16 Holbrook Road as Zayas’ current or recent residence or drug operation base, by demonstrating that codefendant Brenda Koehler currently or recently lived there, and that she and Zayas were currently involved in a close relationship. The second Cl advised the authorities that “Juan” lived at 16 Holbrook Road “with a girlfriend,” described as a “white female,” about thirty years old, with brown hair, whose son also resided at 16 Holbrook Road and “attends” Trinity High School, where he “plays football.” An October 1992 police incident report confirmed that a “Kevin Koehlеr” had sustained an injury while playing football at Trinity High School, identified his mother as Brenda Koehler, “16 Holbrook Road,” telephone number 624-8730. A postal delivery check indicated that Kevin Koehler had received mail at 16 Holbrook Road in 1992. A June 1993 traffic accident report reflected 16 Holbrook Road as Brenda Koehler’s home address. A third confidential informant (“third Cl”) confirmed that “Juan,” who supplied cocaine to workers at the Oasis Social Club, “had a white wife ... in her thirties.”
On February 10, 1994, James McDowell advised the authorities that he had leased a garage at 425 Second Street, Manchester, to Brenda Koehler, who was accompanied by a “Nelson Martell” at the time she signed the lease. The Graffam affidavit failed to disclose the date the lease was signed. McDowell told the authorities that he “believed Brenda Koehler was MartelTs wife,” and advised that Koehler gave “16 Holbrook Road” as her home address, and 624r-8730 as her telephone number. Thereafter, in late February 1994, a motor vehicle registration check disclosed a roughly compatible physical description for Brenda Koehler (“white female,” thirty-four years old, height 5’ 2”, brown hair, brown eyes), and listed her address as 481 Beacon Street, Manchester.
4. Activity at 16 Holbrook Road
In late February 1994, the authorities learned that mail was not “presently” being received at 16 Holbrook Road. Moreover, by this time there was no longer a telephone listing for 16 Holbrook Road. The electrical utility listing nonetheless continued to reflect that Brenda Koehler was the person responsible for payment. Moreover, though the premises were heated by oil, the electrical utility reported the following billings: Oeto-ber-November 1993 ($565 for 4595 kw hours), November-Deeember 1993 ($462 for 3679 kw hours), and December 1993-January 1994 ($600.00 for 5024 kw hours).
5. Graffam,’s Law Enforcement Experience
Finally, based on Graffam’s twenty-two years as a DEA agent, the supporting affidavit stated that active drug traffickers commonly: (1) retain for ready reference, in their residences for extended periods, records relating to their ongoing trafficking activities; (2) assume fictitious names or use nominees to avoid detection; (3) establish surveillance at their operational bases to detect law enforcement activity; and (4) attempt to avoid disclosure or discovery of their actual residences and operational bases by suspending mail and telephone service.
*110 B. The District Court Proceedings
The search conducted pursuant to the challenged warrant disclosed ammunition, cocaine residue, cocaine distributing paraphernalia, substantial cash, and numerous documents detailing Zayas’ ongoing cocaine trafficking activities. In due course, Zayas and ten associates, including Brenda Koeh-ler, were charged with conspiracy to possess cocaine with intent to distribute. 3 See 21 U.S.C. §§ 841(a)(1), 846. Zayas and Koеhler jointly sought to suppress the evidence seized at 16 Holbrook Road, claiming among other things that the Graffam affidavit did not reflect “16 Holbrook Road” as the address at which “Juan” resided or conducted drug operations and that much crucial information in the affidavit was irredeemably “stale.” Zayas stressed in particular that the Graffam affidavit, which identified February 24, 1994, as the date upon which the authorities interviewed the second Cl, nonetheless failed to state when the second Cl last visited with “Juan” at 16 Holbrook Road.
The district court denied the motion to suppress after an evidentiary hearing.
United States v. Zayas-Diaz,
No. 94-30-01-B,
II
DISCUSSION
On appeal, Zayas resurfaces two claims previously presented to the district court: (1) the Graffam affidavit contained insufficient information to provide a substantial basis for finding it probable that evidence relating to Zayas’ drug trafficking activities would be found at 16 Holbrook Road; and (2) the Leon “good faith” exception to the exclusionary rule is unavailing because any reasonably well-trained law enforcement officer would know that the “stale” information in the Graffam affidavit was not adequate to establish probable cause to believe that 16 Hol-brook Road was either Zayas’ recent or current residence or drug operation site; and the more current information neither cured the staleness nor provided an independent basis for a “probable cause” determination.
A. The “Probable Cause” Connection Between Zayas and 16 Holbrook Road
The district court held that the Graffam affidavit afforded probable cause to believe that Zayas resided or conducted drug operations at 16 Holbrook Road in the past. It found the second Cl’s identification of 16 Holbrook Road to be reliable because the authorities were “able to corroborate so much of [his] statement both as to innocent details and as to incriminating matters, such as Zayas-Diaz’s involvement in the cocaine transaction.”
See
Tr. of Suppression Hearing at 107-08 (citing
United States v. Taylor,
1. The “Probable Cause” Standard
For evidence to avert suppression,
see generally Mapp v. Ohio,
Among others, the factors that may contribute to a “probable cause” determination include whether an affidavit supports the probable “ ‘veracity’ or ‘basis of knowledge’ of persons supplying hearsay information,”
id.;
whether informant statements are self-authenticating,
see, e.g., Taylor,
Reviewing courts, including both the district court and the court of appeals, must accord “considerable deference” to the “probable cause” determination made by the issuing magistrate.
See Taylor,
2. The Connection Between Zayas and 16 Holbrook Road 6
Zayas argues that the Graffam affidavit is insufficient because (i) it did not
explic
*112
itly
identify 16 Holbrook Road as the address at which the second Cl visited Zayas on several prior occasions and saw large amounts of cocaine and cash, and (ii) the description of the premises given by the second Cl differed in some respects from the information disclosed in the subsequent aerial surveillance.
See supra
Section I.A.2. We nоte at the outset that this argument ignores the
incriminating network of circumstantial evidence
pointing unmistakably to 16 Holbrook Road as the Bedford residence at which the second Cl had visited Zayas in the past,
see supra
Section I .A. Moreover, its implicit presumption that the second Cl probably led the authorities to premises other than those at which he had visited Zayas is untenable given Graffam’s attestation that the second Cl had demonstrated his reliability in the past.
See United States v. Schaefer,
Our
de novo
assessment of the totality of the circumstances conveyed in the Graffam affidavit persuades us that the issuing magistrate had a substantial basis for crediting the second Cl’s overall reliability, and by extension his identification of 16 Holbrook Road as the locus of his prior visits. The demonstrated reliability of the second Cl, together with the substantial similarity in the physical characteristics of the premises, as described by the second Cl and buttressed by the аerial surveillance of 16 Holbrook Road, provided adequate support for the issuing magistrate’s practical, common-sense “probable cause” determination that the Zayas residence/drug operation base previously visited by the second Cl was located at 16 Holbrook Road in Bedford, New Hampshire.
See Gates,
B. The Stateness Claim.
1. Leon Bypass
The district
court
elected to bypass the merits of the staleness claim that the Graffam affidavit afforded no substantial basis for a “probable cause” finding that Zayas either resided or conducted drug operations within a reasonably recent time frame at 16 Holbrook Road.
See Zayas-Diaz,
No. 94-30-01-B, slip op. at 7.
Leon
allows the trial court, in its “informed discretion,” to bypass the customary “merits” inquiry into whether there existed a “substantial basis” for the probable cause determination made by the issuing magistrate, and simply decide instead whether the challenged search in all events came within the “good faith” exception to the exclusionary rule.
Leon,
2. The Leon Exception
The instant
Leon
“good faith” analysis fundamentally depends upon the “probable cause” concept itself.
See supra
Section II.A.1. The “commission” and “nexus” elements in the “probable cause” analysis each include a temporal component. The issuing magistrate must not only consider the accuracy and reliability of the historical facts related in the affidavits, but must determine,
inter alia,
whether the totality of the cirсumstances reasonably inferable from the affidavits demonstrates a “fair probability” that evidence material to the “commission” of the probable crime will be disclosed at the search premises at about the time the search warrant would issue, rather than at some remote time.
See Sgro v. United States,
As the more serious challenge to the Graf-fam affidavit focuses on its allegedly “stale” information, thus arguably describing events that occurred at some remote earlier time,
see Bucuvalas,
Once the trial court elects to bypass the merits and proceed with the
Leon
analysis, moreover, the “probable cause” focus shifts. Since no deterrent purpose is served by sanctioning “objectively reasonable” law enforcement conduct,
see United States v. Ricciardelli,
The Supreme Court employed four exemplars in
Leon
to outline the ongoing role it envisioned for “exclusionary rule” deterrence in circumstances where evidence is seized pursuant to a search warrant: (1) the magistrate is “misled by information in an affidavit that the affiant knew was false or would have known was false except for his reckless disregard for the truth”; (2) the magistrate “wholly abandon[s] his [detached and neutral] judicial role”; (3) the warrant is “so facially deficient [e.g., failing to list, with sufficient particularity, the еvidence to be seized] ... that the executing officers cannot reasonably presume it to be valid”; or (4) the supporting affidavits are “ ‘so lacking in indi-cia of probable cause as to render official belief in its existence entirely unreasonable.’ ”
Id.
at 923,
With respect to the critical temporal “nexus,” Zayas contends that the Graffam affidavit contained only “stale” information that he resided or conducted drug operations at 16 Holbrook Road, since the second Cl did not specify when he last visited Zayas there. Absent other reliable evidence of a discernible temporal nexus, says Zayas, it was “entirely unreasonable” for the executing officers to rely on the Graffam affidavit as an adequate basis for the required “probable cause” showing. See id. This challenge likewise impermissibly depends, in part, upon the implicit assumption that the second Cl misdescribed exterior features of the premises, but see supra Section II.A, despite the substantially contemporaneous aerial surveillance which essentially corroborated the description given by the second Cl, and notwithstanding Graffam’s vouching for the second Cl’s reliability.
The lone respect in which this aspect of Zayas’
Leon
challenge differs from that discussed above,
see supra
Section II.A, is its focus on Graffam’s undeniable failure to ascribe in the affidavit an approximate date to the second Cl’s last visit with Zayas at 16 Holbrook Road. At this juncture it is important to note that the government must establish “objectively reasonable” reliance on a defective warrant,
see, e.g., Leon,
Were the critical time element presently under discussion otherwise indiscernible within the four comers of the Graffam affidavit, see
Bucuvalas,
Fortunately for the government, other circumstantial indicia buttress the required temporal link. The analysis suggested by Zayas disregards salient inferences which well-trained, objectively reasonable law enforcement officers might draw from the totality of the circumstances disclosed in the Graffam affidavit.
See Gates,
While Zayas would win the latter debate hands-down, he loses the former under Leon’s “objectively reasonable officer” test because the Graffam affidavit describes a collocation of circumstances, as well as expert law-enforcement insights, adequate to enable the recency of the critical last visit by the second Cl to be fairly inferrеd.
See United States v. Jewell,
As to the “commission” element, the ongoing nature of Zayas’ cocaine trafficking activities in the Manchester area was amply demonstrated in the supporting affidavit: first, by Sosa’s admission that Zayas had supplied the six ounces of cocaine seized from Sosa’s residence on January 26, 1994, the date of Sosa’s arrest; and by the second Cl, who informed the Manchester police on February 24, 1994 — twelve days before the challenged search — that Zayas, alias “Juan,” “currently controls” cocaine distribution at various Manchester business establishments, including the Oasis Social Club. See supra Section I.A.1.
As to the “nexus” element, the pivotal linkage was the second Cl’s statement that “Juan lives” in Bedford, where on “several occasions” the second Cl had visited “Juan” and seen cocaine and cash in substantial quantities. Thоugh imprecise, these temporal references were related by the second Cl in the present tense, which at the very least would permit an objectively reasonable officer to infer that the occurrences described were substantially contemporaneous with the second Cl’s interview, which in turn took place within twelve days of the warrant application. The second Cl’s description of various exterior features of 16 Holbrook Road, as substantially corroborated by virtually contemporaneous aerial surveillance, likewise lent to the probability that his last visit had been relatively recent, rather than remote in time. The few minor discrepancies in thе second Cl’s descriptive account were by no means necessarily attributable to a substantial time lapse. See Schaefer, 87 F.3d *116 at 567 (noting that “magistrate may reasonably choose to ... disregard petty inconsistencies” in informants’ statements). Finally, the second Cl made statements that plainly imply regular, ongoing transactions at 16 Holbrook Road, e.g., that “[S]panish males” arrived “every Tuesday” at the Bedford residence in automobiles bearing New York license plates.
Absent any indication or suggestion that Graffam purposely withheld more precise temporal references adverse to the warrant application,
see supra
note 9, it would be pure speculation to credit Zayas’ implicit premise thаt the last visit the second Cl had with Zayas at 16 Holbrook Road was necessarily remote in time even though there was probable cause to believe that Zayas was still trafficking cocaine less than two weeks before the search.
See, e.g., id.
at 568 (“[I]t is common ground that drug conspiracies tend to be ongoing operations, rendering timely [two- or three-year-old] information that might, in other contexts, be regarded as stale.”);
United States v. Hernandez,
To this must be added the weight due Graffam’s insights into drug trafficking modi operandi, based on more than two decades as a DEA agent. See supra Subsections I.A.4 & I.A.5. Given Graffam’s expertise, it would be “objectively unreasonable” to conclude, as Zayas simply presumes, that mere stoppage of postal deliveries and electrical utility services, or the use, listing, and/or maintenance of other residential addresses, or nominee owners such as Brenda Koehler, compelled an inference that Zayas was no longer residing, conducting drug operations, or keeping illicit drug-related recоrds, at 16 Holbrook Road. Thus, in no sense would it have been objectively unreasonable for a well-trained police officer to believe there was a fair probability that these developments were subterfuges prompted by Sosa’s recent arrest and designed to prevent detection, as the Graffam affidavit indicated. See id.
Ill
CONCLUSION
We therefore conclude that a well-trained law enforcement officer reasonably could have relied upon the Graffam affidavit as adequate support for the issuing magistrate’s finding that there was a fair probability that drug trafficking records would be found at 16 Holbrook Road on March 8, 1994. Accordingly, the district court judgment is affirmed.
Notes
. The criminal investigation was conducted by federal, state, and local law enforcement authorities, to whom we refer collectively as "the authorities.”
. For ease in reference, we assume all confidential informants were male.
. The nine other defendants entered guilty pleas. The government does not now contend that Za-yas lacked an objectively reasonable expectation of privacy in the 16 Holbrook Road premises at the time the search was conducted.
See, e.g., United States v. Bouffard,
. Following a five-day jury trial, Zayas was found guilty on the conspiracy charge. The. district court later sentenced him to 360 months.
.
See Gates,
. We review the district court’s factual findings (if any) only for clear error, but we review
de novo
its ultimate determination that a given set of facts constituted “probable cause.”
See United States v. Schaefer,
. In addition, the second Cl related prior criminal activity by Zayas (e.g., dumping cocaine over an embankment in 1992 at the time he was arrested in Connecticut) and descriptions of exterior and interior features at 16 Holbrook Road.
See Taylor,
. Leon identifies importаnt prudential considerations that inform the discretionary bypass decision at the suppression stage.
If the resolution of a particular Fourth Amendment question is necessary to guide future action by law enforcement officers and magistrates, nothing will prevent reviewing courts from deciding that question before turning to the good-faith issue. Indeed, it frequently will be difficult to determine whether the officers acted reasonably without resolving the Fourth Amendment issue. Even if the Fourth Amendment question is not one of broad import, reviewing courts could decide in particular cases that magistrates under their supervision need to be informed of their errors and so evaluate the officers’ good faith only after finding a violation. In other circumstances, those courts could reject suppression motions posing no important Fourth Amendment questions by turning immediately to a consideration of the officers' good faith. We have no reason to believe that our Fourth Amendment jurisprudence would suffer....
Leon,
. Zayas does not claim, for example, that the second Cl told the authorities the date he last visited Zayas at 16 Holbrook Road, nor that such information was deliberately or recklessly omitted from the Graffam affidavit.
See, e.g., Craig,
. In our own case, the district court relied on the following four grounds. First, in describing his "several” visits to 16 Holbrook Road, the second Cl stated that Juan “lives,” and "deals” drugs, in Bedford. Zayas-Diaz, No. 94-30-01-B, slip op. at 8. Next, the follow-up aerial surveillance of 16 Holbrook Road "substantially” corroborated the second Cl’s description of the residential grounds at 16 Holbrook Road. Id. Third, Marcello Sosa admitted that his cocaine supplier, "Juan,” “lived” in Bedford. Id. at 8-9. Finally, the statements James McDowell made to the authorities in February 1994 — that "Nelson Martell" (Zayas) had been with Brenda Koehler when she leased the McDowell garage, and the two "appear[ed] to be husband and wife” — provided some further support for a reasonable inference that Koehler and Zayas lived together at 16 Holbrook Road. Id. at 9.
. The affidavit would enable a reasonably well-trained police officer to conclude that the second Cl was a reliable informant, based both on Graf-fam’s vouching and on the very detail of the second Cl’s information about "Nelson Martell” [Zayas], particularly the earlier cocaine-related arrest in Connecticut, see supra note 7, which Graffam verified with the Connecticut police before the affidavit was submitted.
