Grundy County, Missouri, has about 9,800 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Grundy County Sheriff's Office and one city 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 Prosecuting Attorney files charges, a case in the Grundy County Circuit 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 Grundy County
The Grundy County Sheriff's Office is the county agency that reports arrests to the FBI for Grundy County. It reported 6 arrests for 2025.
The FBI lists one city in Grundy County with a reporting agency of its own:
- Trenton, 5,588 residents: 72 arrests reported for 2025.
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.
How Many Arrests Each Agency Reports in Grundy County
Each agency reports its arrests to the FBI by month, and the FBI publishes them 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.
- Trenton: 72 for 2025, 64 for 2024, 85 for 2023, 63 for 2022, 104 for 2021 and 66 for 2020.

Together, the two agencies with all twelve months of 2025 on file reported 78 arrests that year. The same agencies with both 2025 and 2024 complete reported 78 in 2025 against 67 in 2024, up 16 percent.
Through April 2026, the two agencies with every month so far on file reported 22 arrests, against 22 in the same months of 2025.
Booking: Where People Arrested in Grundy County Are Held
A person kept in custody after an arrest in Grundy County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2019 the jail held about 20 people. Its rated capacity in 2019 was 30 beds, and it ran at 67 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 Grundy County
An arrest in Grundy County can be traced in two places, depending on where the case stands: Case.net, the Missouri courts' free statewide case search, which shows whether charges were filed; the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at grundycountymo.com/wordpress/prosecuting-attorney, phone 660-265-3333).
Missouri is one of the states that lets anyone look up another person's statewide criminal history: the open record search on the MACHS site lets anyone check convictions by name, through the Missouri State Highway Patrol Criminal Justice Information Services Division. 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 Grundy County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Missouri Sunshine Law the agency must answer within 3 business days, and it may charge research time and copying.
- An arrest by the Grundy County Sheriff's Office: ask its records unit, reached through the office at 660 359 2828.
- An arrest in Trenton: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 660-265-3333, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
