Marshalltown, Iowa, in Marshall County, has about 28,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 Iowa District Court for Marshall County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Marshalltown
The FBI lists Marshalltown with an arrest reporting agency of its own, filed as Marshalltown Police Department. It reported 902 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Marshall County Sheriff's Office is the county agency. It reported 382 arrests for 2021.
How Many Arrests Marshalltown Reports
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.
- Marshalltown: 902 for 2025, 937 for 2024, 1,130 for 2023, 991 for 2022, 950 for 2021 and 1,076 for 2020.
Marshalltown's 902 arrests in 2025 were down 3.7 percent from 937 in 2024.
Through August 2026, Marshalltown reported 520 arrests, against 619 in the same months of 2025.
Booking: Where People Arrested in Marshalltown Are Held
The county jail is where a person arrested in Marshalltown 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 2023 the jail held about 110 people, down from about 140 in 2019. Its rated capacity in 2023 was 157 beds, and it ran at 69 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Marshall County Sheriff's Office at sheriffmarshallcounty.org/current-inmate-roster (page title: Private Site), which answered when SearchSystems opened it on October 9, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A person sentenced to prison serves the sentence in a facility of the Iowa Department of Corrections, whose inmate locator is at doc.iowa.gov/inmate-family-services.

Iowa is one of the states that lets anyone look up another person's statewide criminal history: anyone can request a name-based criminal history check online, through the Iowa Division of Criminal Investigation. 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 Marshalltown
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Iowa Open Records Law (Chapter 22) the agency must answer without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, and it may charge the actual cost of copying and retrieval.
