Daniel Chrobak appeals his conviction for possession and transport in interstate commerce of child pornography in violation of 18 U.S.C. § 2252. At trial, Chrobak moved to suppress evidence obtained from his home, asserting a defective warrant. The district court 1 denied his motion, and Chrobak entered a plea of guilty conditioned upon the outcome of this appeal pursuant to Federal Rule of Criminal Procedure 11(a)(2). We affirm.
On July 27, 1998, investigators from the Nеw York State Attorney General’s office observed a transmission of fourteen images on a newsgroup website known to be frequented by child pornograрhers and pedophiles. 2 This transmission contained several images of undisputed child pornography. The sender of the images identified himself as “Post@them.now.” Thе records of Post@them.now’s internet service provider revealed the moniker was registered to one Daniel Chrobak of North Little Rock, Arkansas. The New York authorities forwarded the images and their information to the FBI in Arkansas.
Special Agent Jill Hill, the coordinator of the FBI’s Crimes Against Children office in Little Rock, Arkаnsas, received the information. Her superiors informed her they wished to search Chrobak’s home on October 27, 1998, in conjunction with the execution of search warrants nationwide against members of Pedo University. Through Freedom of Information Act requests to the U.S. Post Office and Chro-bak’s telephone service provider, Agent Hill learned that Chrobak resided in a mobile home on Old Tom Box Road in Jacksonville, Arkansas. She surveilled the address and observed a vehicle rеgistered to Chrobak parked out front.
Agent Hill applied for a search warrant. She described the activities of the New York Attorney General’s officе. She recounted the evidence pointing to the mobile home on Old Tom Box Road as Daniel Chrobak’s residence. She described her training and expеrience in investigating *1045 child pornography and the sexual exploitation of children. She described the images as “graphic files depicting minors engaged in sexually explicit conduct,” and stated: “Your affiant reviewed the transmitted images and determined that they depict sexually explicit conduct involving childrеn under the age of 16.” She also stated that child pornographers “almost always maintain and possess their materials in a place considered sеcure due to its inherent illegality.” The magistrate judge issued a search warrant on the basis of Agent Hill’s affidavit.
On October 27, 1998, police executed the warrant at Chrobak’s residence. Agents seized his computer, computer disks, and a three ring binder containing child pornography. Forensic examination revealеd the computer and disks contained thousands of images of child pornography. The sole question we must address is whether the search warrant for Chrobak’s hоme was valid.
I.
Chrobak asserts the magistrate judge failed to make an independent judicial determination that the images were child pornography and, thus, nоt protected by the First Amendment. To make this determination, the judge must either view the images or rely on a detailed factual description of them.
New York v. P.J. Video, Inc.,
Chrobak argues they were not. He cites the Supreme Court’s obscenity jurisprudence for the proposition that con-clusory allegаtions by police that materials are obscene are insufficient.
See Lee Art Theatre, Inc. v. Virginia,
We disagrеe. Agent Hill’s language is almost identical to the language of 18 U.S.C. § 2252 (“visual depiction involv[ing] the use of a minor engaging in sexually explicit conduct”) for which Chrobak wаs convicted. Under
United States v. Koelling,
*1046 II.
Chrobak also makes two arguments аgainst a finding of probable cause. He asserts someone else might have used his email address and Agent Hill performed an insufficient investigation to prove otherwise. He also notes the images were transmitted ninety-one days prior to execution of the warrant and asserts that evidence was too stale to provide probable cause that images would be found in Chro-bak’s home at the time of the search.
Again, we disagree. Probable cause means a “fair probability that ... evidence of a crime will be found in a particular place.”

Chrobak’s staleness argument also falls short. There is no bright line test for staleness.

The judgment of the district court is AFFIRMED. 3
