Criminal Cases in the Canyon County District Court

The Idaho Criminal History and Your Own Copy
Idaho is one of the states that lets anyone look up another person's statewide criminal history: name-based conviction checks are open to the public, through the Idaho State Police Bureau of Criminal Identification. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a fingerprint-based request to the Bureau of Criminal Identification. The state page SearchSystems verified for it is at isp.idaho.gov/bci/criminal-history.
Arrest Records Kept Locally in Nampa
The Canyon County Sheriff's Office and the agency that reports for Nampa (filed by the FBI as Nampa Police Department) keep the arrest records in and around Nampa: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
Together, the five agencies in Canyon County with all twelve months of 2025 on file reported 4,145 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Nampa arrest records.

Asking an Agency in Canyon County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Idaho Public Records Act a county office must answer a request within 3 working days, or 10 when more time is needed, and it may charge copying after the first 100 pages and labor after the first two hours. The county records request page SearchSystems verified is at canyoncounty.id.gov/public-records-request (page title: Public Records Request | Canyon County).
