OPINION
Scott Ward appeals his conviction of fifth-degree possession of a controlled substance on the ground that the warrant authorizing the search during which the narcotics were discovered was not supported by sufficient probable cause. We reverse.
FACTS
On July 3, 1996, Douglas Rauenhorst, a Blue Earth County Peace Officer assigned to the multi-jurisdictional Minnesota River Valley Drug Task Force, submitted a four-paragraph affidavit in support of his application for a warrant to search room 176 of the Best Western Garden Inn in North Mankato. The first paragraph of the affidavit identified the affiant and the Task Force. The next two paragraphs stated:
Within seventy two hours on either side of a date July 2, 1996 a Confidential Informant hereinafter referred to as a Cl entered the room 176 at the Best western [sic] Garden Inn in North Mankato. The Cl was able to obtain a small sample of a green vegetable material. The field test indicated that the substance was marijua *70 na. The field test was conducted by the affiant.
A check of the records at the motel indicate that the room is rented by a male named Scott Ward.
The final paragraph listed items commonly found in the possession of drug dealers. The record does not show that any additional information was supplied to the issuing judge.
The judge issued a search warrant, which police executed on the evening of July 3. The search uncovered 228 grams of marijuana, assorted drug paraphernalia, and $6,700. Ward was charged with fifth-degree possession of a controlled substance and with possession of marijuana without tax stamps; the prosecutor subsequently dropped the latter charge.
At the omnibus hearing, Ward challenged the validity of the warrant on probable cause grounds. Officer Rauenhorst’s supervisor testified that the informant obtained the marijuana during a controlled buy, and Ward testified that he had been occupying the hotel room since July 1. Finding the case “very close,” the court upheld the validity of the warrant on the grounds that admitting to the possession of marijuana was against the informant’s penal interest and that doubtful or marginal cases should be decided in favor of validity of the warrant.
Ward proceeded on stipulated facts, while preserving his right to appeal the probable cause issue. He was found guilty and sentenced to five years probation and a $2,000 fine. He now appeals from the probable cause determination, and we reverse.
ISSUE
Did the district court err in concluding that the affidavit provided sufficient probable cause to support issuance of the search warrant?
ANALYSIS
I. Probable Cause Standards
A. General standards
Hotel guests have a sufficient expectation of privacy in their rooms to give rise to Fourth Amendment protections against search and seizure.
State v. Williams,
A determination of probable cause for the issuance of a search warrant is entitled to great deference, but where the facts are not in dispute, this court must independently apply the case law.
State v. Richardson,
Probable cause has been defined variously as “the objective facts” that under the circumstances would cause “a person of ordinary care and prudence [to] entertain an honest and strong suspicion that a crime has been committed,”
State v. Johnson,
Minnesota has adopted the United States Supreme Court’s “totality of the circumstances” test for determining whether probable cause exists.
Wiley,
“The law of probable cause prevents the issuance of a search warrant on the basis of vague and uncertain information.”
State v. Jannetta,
B. Informants
Where a probable cause determinar tion is based on an informant’s tip, the informant’s veracity and the basis of his or her knowledge are considerations under the totality test.
State v. Albrecht,
Minnesota courts have identified six considerations bearing on the reliability of an informant who is confidential but not anonymous to police. A first-time citizen informant who has not been involved in the criminal underworld is presumed to be reliable, but the affidavit must specifically aver that the informant is not involved in criminal activity.
State v. Siegfried,
An informant’s reliability may be established by sufficient police corroboration of the information supplied, and corroboration of even minor details can “lend credence” to the informant’s information where the police know the identity of the informant.
See id.
at 269. Where an informant voluntarily comes forward (without having first been, arrested) to identify a suspect, and in the absence of a motive -to falsify information, the informant’s credibility is enhanced because the informant is presumably aware that he or she could be arrested for making a false report.
Gabbert,
Finally, the fact that an informant makes a statement against his or her own penal interest “is of some minimal relevance in a totality-of-the-cireumstanees analysis.”
McCloskey,
the typical “stool pigeon” who is arrested and who, at the suggestion of the police, *72 agrees to cooperate and name names in order [to] curry favor -with the police.
Id.
at 703. The rationale for the credit given to statements against interest is that “[people do not lightly admit a crime and place critical evidence in the hands of the police in the form of their own admissions.”
State v. Wiberg,
We have found no reported Minnesota cases upholding warrants based on informants’ statements against interest where there has not been some corroboration or other indicium of reliability.
See State v. Yahnke,
C. Time-place nexus
“Probable cause to search exists if it is established [that] certain identifiable objects * * * may probably be found at the present time.”
Jannetta,
In general, a single incident of criminal activity, such as a sale of contraband, “will support a finding of probable cause only for a few days at best.”
State v. Cavegn,
cannot ignore the fact that in eases involving controlled purchases by informants, police often must wait a number of days before obtaining and executing a warrant if they are to avoid compromising the informant.
Id. at 674.
The likelihood that the evidence sought is still in place is a function not simply of watch and calendar but of variables that do not punch a clock: the character of the crime (chance encounter in the night or regenerating conspiracy?), of the criminal (nomadic or entrenched?), of the thing to be seized (perishable and easily transferable or of enduring utility to its holder?), of the place to be searched (mere criminal forum of convenience or secure operational base?), etc.
State v. Yaritz,
We have found no Minnesota case law addressing the timing issue in relation to a search of a location other than a suspect’s home or car.
Cf. State v. Sherwood,
II. Application in the Instant Case
Ward identifies two defects in the warrant application: (1) the absence of any information other than a possible statement against interest regarding the credibility or reliability of the informant and (2) the absence of any link between Ward and the hotel room on any day other than July 3. or between Ward and a drug transaction at any time. Both contentions have merit.
As noted, it is questionable whether a statement against interest, standing alone, can render an informant credible. The purchase of marijuana places the informant beyond the scope of the first-time citizen informer rule.
See McCloskey,
From the language of the affidavit, it is impossible to tell with any certainty whether (1) the informant obtained the marijuana in a controlled buy, (2) the informant came forward voluntarily, or (3) the informant was a “stool pigeon” attempting to implicate others for his own benefit. Indeed, because “controlled purchase” is an accepted term of art, the most logical assumption is that this was
not
a controlled purchase because an experienced drug enforcement officer would have identified it as such in the affidavit. The affidavit as written is therefore susceptible of at least two reasonable interpretations, one of which, the “stool pigeon” scenario, would not supply probable cause, and the affidavit provides no basis for favoring one over the other. We conclude that this “vague and uncertain information,” .
Jannetta,
355 N'.W.2d at- 193, does not supply “sufficient underlying facts so that the magistrate may draw his own conclusions” as to the reliability of the informant.
Hanson,
As to the issue of an “object-place nexus,”
see Kahn,
We conclude that in order to support a warrant to search a hotel room, the affidavit must provide some indication that the room is still occupied by a person who was present at the time of the incident that gave rise to probable cause. If the affidavit suggests that the suspect is the tenant or his invitee, this might be accomplished by a simple averment that the room remains registered in the same name. We believe that allowing a magistrate to infer continued occupancy from a silent affidavit would create an unacceptable risk of invasion of the constitutionally protected privacy of innocent subsequent tenants.
The district court relied largely on the maxim that reviewing courts should defer in “doubtful or marginal cases.”
See Wiley,
The affidavit in this case provides significantly less information than the “doubtful or marginal” one in
McCloskey.
As Ward argues, it more closely resembles the affidavit found “deficient on its face” in
Meizo,
which simply gave the defendant’s name and address and stated that, during a three-day period, four confidential informants made claims that they purchased drugs at unspecified times from the defendant.
Meizo,
As the district court noted, the rationale for the rule of deference in marginal cases is that
the exclusionary rule is directed at police misconduct. Here the police officer acted in good faith and did his best to comply with the Fourth Amendment requirements by going to a magistrate and relying on the magistrate to make a determination of probable cause. Applying the exclusionary rule in such a case would not deter police misconduct but would punish good police conduct.
State v. Buchholtz,
The state urges this court to reconsider its decision not to adopt the federal exception to the exclusionary rule for evidence seized in good faith pursuant to a warrant later found invalid.
See, e.g., Kahn,
*75 DECISION
Because the affidavit in support of the search warrant fails to establish the reliability of the confidential informant or any link between Ward and the drug transaction other than his occupancy, possibly as long as four days later, of the room in which the transaction took place, it does not provide sufficient probable cause to support issuance of the warrant. All evidence- obtained from Ward’s hotel room must therefore be suppressed, and because that evidence provided the sple basis for Ward’s conviction, the conviction must be reversed.
Reversed.
Notes
. We disagree with the state's contention at oral argument that the standard of review established in
Richardson
represents an anomaly in the law. It is well established that appellate courts review issues of law, such as the interpretation of precedent, without deference to the district court's determinations.
Frost-Benco Elec. Ass'n v. Minnesota Pub. Utils. Comm’n,
. We note that the affidavit in this case states only that the informant "obtained” marijuana from the room; it does not aver that the tenant of the room sold marijuana to the informant. On the face of the affidavit, the marijuana could have belonged to a hotel employee. Indeed, at the omnibus hearing, Ward's counsel articulated a suspicion that the informant was another occupant of the room, who was both a marijuana user and a practiced "stool pigeon.” The affidavit as written does not foreclose the possibility that the marijuana came from the informant’s own supply-
