The United States appeals from two orders of the District Court suppressing evidence against defendants. Lawrence D. and Patricia L. LaMorie. Because we conclude that the warrant under which the LaMories’ trailer home was searched was supported by probable cause, we reverse and remand.
I.
On April 13, 1995, the post office and convenience store in Arena, North Dakota, were burglarizеd and burned to the ground. Federal and state law enforcement officials began investigations, and on May 3, 1995, Deputy Steven Hall of the Burleigh County Sheriffs Department applied for a warrant to search the LaMories’ trailer home in Wing, North Dakota.
Deputy Hall appeared before Burleigh County District Judge Benny Graff in connection with the warrant application and testified that soon after the Arena burglary, postab money orders stolen from the Arena post office began to appear in the Bismarck area. Store employees gave physical descriptions of the persons cashing the money orders and indicated that they used New York identification. Another deputy stationed in Wing had information that two families of New Yorkers were in the. process of moving to . Wing, and their physical descriptions matchеd the descriptions given by the store clerks in the Bismarck area. A federal postal inspector had identified five suspects in the post office burglary and the cashing of the stolen money orders: Lawrence and Patricia LaMorie, Jerry and Vicki Allen, and Jeffrey Royce. All five suspects were from New York and had recently ar *551 rived in North Dakota. The Allens and Royee were the first to move into the trailer homе, which Patricia LaMorie had recently inherited, and the LaMories later joined them. Royee had been positively identified passing a stolen money order in Wing on April 22.
On May 2, the day before Deputy Hall applied for the warrant, officers in West Fargo arrested the Allens for possession of a controlled substance. When they were arrested, the Allens had in their possession money orders stolen from the Arena post office. In separate interviews with the West Fargo police, the Allens implicated themselves in the Arena burglary, the burning of the post office, and the ongoing scheme to pass the stolen money orders. The Allens also implicated Royee, but they apparently did not implicate the LaMories in the burglary at that time. On the morning of May 3, Deputy Hall interviewed Vicki Allen by telephone, and she told him that prоperty stolen from the Arena post office had been transported to the trailer in Wing where the Al-lens and the LaMories were living, Allen indicated that the money order validation machine from the Arena post office had been set up in the kitchen of the trailer, where the burglars validated approximately $26,000 in blank money orders. Stamps, blank money orders, and costume jewelry from the convenience store also had been taken to the trailer, according to Allen. Deputy Hall testified that Allen told him that the LaMories were out of town but were expected to return to Wing by the weekend. 1
Hall also noted that Allen and other investigators on the case had indicated that Lawrence LaMorie had a lengthy criminal record, was in possession of several firearms, and was extremely dangerous. After hearing this evidеnce, Judge Graff granted the search warrant for the LaMories’ trailer. Because of Lawrence LaMorie’s criminal history and the evidence that he was dangerous, the judge granted a “no-knoek” warrant in accordance with state law, meaning that the officers executing the warrant were not required to knock or announce their presence before entering the property.
Officers exеcuted the warrant on May 4, discovering costume jewelry matching Vicki Allen’s description but none of the other, property she claimed would be in the trailer. In plain view, however, the officers discovered a semi-automatic rifle, a sawed-off shotgun, and ammunition. Lawrence LaMorie was indicted by a federal grand jury as a felon in possession of the firearms and ammunition, in violation of 18 U.S.C. § 922(g)(1) (1994), and both LaMories werе indicted for possession of the unregistered sawed-off shotgun, in violation of 26 U.S.C. § 5861(c), (d) (1994).
Patricia LaMorie moved to suppress the firearms. A magistrate judge recommended suppression, finding that Deputy Hall presented no evidence of Vicki Allen’s reliability or corroboration of the information provided by her. The Magistrate Judge also noted that Hall failed to disclose to Judge Graff that Allen was a convicted felon and concluded that her disclosures were too stale to support a finding of probable cause. Finally, the Magistrate Judge found that the warrant was so lacking in indicia of probable cause that the good-faith , exception of
United States v. Leon,
The District Court ordered the evidence' suppressed, repeating the Magistrate Judge’s reasons and adding a concern “that the purpose of the search was the weapons themselves, not any alleged ‘fruits of a crime.’” Memorandum and Order at 3. Lawrence LaMorie then moved the court to suppress the weapons as evidence against *552 him, and the District Court granted his motion.
We have jurisdiction over the government’s appeal pursuant to .18 U.S.C. § 3731 (1994). “In reviewing the grant ..., of a motion to suppress evidence on Fourth Amendment grounds, we are bound by the district court’s findings of fact ... unless we believe on the basis of the record as a whole that the District Court clearly erred.”
United States v. Riedesel,
II.
We consider first the District. Court’s suggestion that the search was unconstitutional because “the purpose of the search was the weapons themselves.” Memorandum and Order аt 3. The District Court continued:
The moral is clear — if you want to search for weapons, say so and do so, and don’t try to seam the court with vague references to “suspects” and stolen property. Assembling a small army of heavily armed law enforcement officers to look for a “crock, brown and tan in color, approximately 2 feet high” [one of the items on the warrant] looks inappropriatе.
Id.
at 3-4. The LaMories have pressed similar arguments on appeal. With due respect to the District Court, the fact that the officers may have been interested in looking for weapons in the LaMories’ residence is irrelevant to the constitutional inquiry if the search warrant for the proceeds of the burglary was valid.
Horton v. California,
III.
The duty of the judge issuing a search warrant is to make a “practical, common-sense decision” whether, considering all the circumstances, a reasonable person would have reason to suspect that evidence would be discovered.
Illinois v. Gates,
We agree with the government that Judge Graff had a substantial basis for concluding that probable cause existed to search the trailer. Deputy Hall presented a detailed description of the various law enforcement authorities’ investigations into the burglary, investigations that eventually focused on the, Allens, the LaMories, and Royee. Vicki Allen, under arrest for another offense, reported that fruits of the burglary hаd been taken to the LaMories’ trailer and that the LaMories were out of town. Jerry Allen corroborated the details of the burglary un *553 der separate questioning. Vicki Allen described to Deputy Hall particular items stolen from the post office that could be found in the trailer. Taken together, this information would give a reasonable person reason to suspect that the fruits of the burglary could be found in the trailer.
A.
We consider the LaMories’ arguments in turn. First, they argue that Judge Graff had before him insufficient evidence of Vicki Allen’s credibility and reliability. The credibility and reliability of a person providing information to the police are important factors to be considered in a determination of probable cause.
See Gates,
It is clear in this case that Vicki Allen’s basis of knowledge for the information she provided is well established: she admitted participating in the crimes. The LaMories fault Deputy Hall for not interviewing Allen in person to verify her credibility. Although personal contact with an informant can strengthen an officer’s decision to rely on the information provided,
see Robertson,
On the issue of reliability, the LaMories argue that the police did not attempt to corroborate Allen’s information to verify that it was truthful. We note first that some of Viсki Allen’s information was corroborated by the independent questioning of her husband. If some information from an informant is shown to be reliable because of corroboration, it is a permissible inference that other, uncorroborated information is also reliable.
See Edmiston,
B.
The District Court also concluded that the information provided by Allen was too stale to support a finding of probable cause. Probable cause must exist when a warrant is issued, not merely at some earlier time.
See United States v. Ozar,
We believe the District Court erred on this point.
There is no bright-line test for determining when information is stale. Whether the averments in an affidаvit are sufficiently timely to establish probable cause depends on the particular circumstances of the case, and the vitality of probable cause cannot be quantified by simply counting the number of days between the occurrence of the facts supplied and the issuance of the affidavit. Time factors must be examined in the context of a specific case and the nature of the сrime under investigation.
United States v. Koelling,
IV,
The government also contends that the District Court incorrectly analyzed two issues raised by the LaMories under the doctrine of
Franks v. Delaware,
The second claim has little more substance. According to the LaMories, Deputy Hall intentionally or recklessly failed to disclose to Judge Graff that Vicki Allen was a convicted felon, which necessarily affected the judge’s assessment of hеr credibility. We will assume that Deputy Hall was aware that Allen was a convicted felon, though the record suggests he was not. Nevertheless, we conclude that the omission was not material. Deputy Hall clearly disclosed to Judge Graff that Allen had confessed to participating in the burglary and torching of a post office, as well as a scheme to validate and cash stolen money orders. The judge could hardly have been under the impression that Allen was a model citizen. In light of this information and the evidence supporting Allen’s credibility, we cannot agree with the District Court that the details of her criminal record would have had any effect on the search warrant proceeding.
See Ellison,
V.
Even if the warrant wеre not supported by probable cause, we would agree with the government that reversal would be required because of the' good-faith exception of
United States v. Leon,
In
Leon,
the Supreme Court recognized that “the exclusionary rule is designed to deter police misconduct rather than to punish the errors of judges and magistrates.”
Leon,
(1) where the issuing judicial officer was misled by information in an affidavit that the affiant knew was false or would have known was false except for his reckless disregard of the truth; (2) where the issuing officer “wholly abandoned his judicial role;” (3) where the affidavit supporting the warrant contained so few indicia of probable cause “as to render official belief in its existence entirely unreasonable;” and (4) where the warrant itself is so facially deficient that no executing officer could reasonably presume it to be valid.
Id.

Leon,
YI.
The orders of the District Court suppressing evidence discovered pursuant to the search of the LaMories’ trader home are reversed, and the case is remanded to the District Court for further proceedings.
Notes
. At the suppression hearing, Deputy Hall testified about an additional conversatiоn he had with Judge Graff concerning the credibility of Vicki Allen. Because this conversation was not reported in the transcript of the search warrant proceeding, and because it apparently took place after Judge Graff had signed the search warrant, the District Court declined, to consider-it. We will do the same.
. The Magistrate Judge also recommended, and the District Court ordered, the suppressiоn of statements obtained by officers from Patricia La-Morie in violation of
Miranda v. Arizona,
. In Upton, police had been looking for items taken in several home burglaries. An anonymous telephone caller, who later admitted to being Upton’s ex-girlfriend, informed the police that she had seen the goods in a motor home behind Upton’s house. An officer verified that the motor home was parked where the caller said it would be and then obtained a search warrant. The Supreme Court summarily reversed a state-court decision suppressing the evidence.
