Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026. The jail figures are from the Vera Institute of Justice's Incarceration Trends data.
Lyon County, Minnesota, has about 26,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Lyon County Sheriff's Office, three city agencies and one state agency. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the County Attorney files charges, a case in the Lyon County District Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Lyon County
The Lyon County Sheriff's Office is the county agency that reports arrests to the FBI for Lyon County. It reported 84 arrests for 2024, its latest complete year.
Arrests inside three of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Marshall, 13,996 residents: 266 arrests reported for 2025.
- Tracy, 2,041 residents: 10 arrests reported for 2022.
- Minneota, 1,355 residents: 3 arrests reported for 2024.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
The FBI's agency list also places one more agency in Lyon County: the State Patrol at Marshall (state police).
How Many Arrests Each Agency Reports in Lyon County
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Marshall: 266 for 2025, 303 for 2024, 279 for 2023, 254 for 2022, 257 for 2021 and 244 for 2020.
- Lyon County Sheriff's Office: 84 for 2024, 78 for 2023, 86 for 2022, 94 for 2021, 72 for 2020 and 80 for 2019.
- Minneota: 3 for 2024, 3 for 2023, 2 for 2022, 3 for 2021 and 7 for 2019; 2020 is missing months.
- Tracy: 10 for 2022, 24 for 2021, 20 for 2020 and 30 for 2019.
Together, the three agencies with all twelve months of 2024 on file reported 390 arrests that year. The same agencies with both 2024 and 2023 complete reported 390 in 2024 against 360 in 2023, up 8.3 percent.
Tracy reported only part of 2024 (11 months) and is left out of the totals.
Booking: Where People Arrested in Lyon County Are Held
The county jail is where a person arrested in Lyon County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2021 the jail held about 28 people, down from about 36 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 67 beds, and it ran at 53 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
How to Find Out About an Arrest in Lyon County
For Lyon County the place to look is Minnesota Court Records Online, the Minnesota Judicial Branch's free statewide case search, which shows whether charges were filed.
Minnesota is one of the states that lets anyone look up another person's statewide criminal history: the public criminal history search online is free and shows 15 years of convictions, through the Minnesota Bureau of Criminal Apprehension. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Lyon County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Minnesota Government Data Practices Act the agency must answer promptly, within a reasonable time, and it may charge copying, and staff time for requests over 100 pages.
- An arrest by the Lyon County Sheriff's Office: ask its records unit.
- An arrest in Marshall, Tracy or Minneota: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- An arrest by the State Patrol at Marshall: the records office of the agency involved.
- Your own statewide record: a request to the Bureau of Criminal Apprehension.
