Criminal Cases in the Superior Court of California, County of Napa
In California the public criminal record is the court file. Criminal cases from American Canyon are heard by the Superior Court of California, County of Napa, which hears every civil, criminal, family, probate, traffic and juvenile case, and the file of each case is kept by the Superior Court clerk.
The court records page SearchSystems verified for the county is at napa.courts.ca.gov/research-records (page title: Research & Records | Superior Court of California | County of Napa), phone (707) 299-1140, which answered when SearchSystems opened it on September 23, 2026.
California has no single public index of every trial court case; each court's records are looked up through that court.
The California Criminal History and Your Own Copy
The statewide criminal history kept by the California Department of Justice is closed to the public in California: it is released to its subject and to authorized employers and licensing agencies, and a member of the public uses the court's own case index instead.
To see your own record, the route is a Record Review through Live Scan fingerprinting, form BCIA 8016RR; the state fee is $25. The response cannot be used for immigration or visa purposes. Details are on the California Department of Justice page.
Arrest Records Kept Locally in American Canyon
The Napa County Sheriff's Office and the agency that reports for American Canyon (filed by the FBI as American Canyon Police Department) keep the arrest records in and around American Canyon: 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.
The FBI's agency list also places two other agencies, one state agency and one state police unit in Napa County (the arrest records guide names each one); each keeps the records of its own arrests.
Together, the six agencies in Napa County with all twelve months of 2025 on file reported 2,071 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 American Canyon arrest records.
The Crimes Behind the Records: American Canyon in 2025
The agency that reports for American Canyon had 87 violent and 252 property crimes reported for 2025; each one is a report on file with it, and each arrest that follows is the start of a criminal record.

Asking an Agency in Napa 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 California Public Records Act a county office must answer a request within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
