Marion Arrest Records: Who Makes Arrests, Where People Are Booked and How to Get the Report

Who Makes Arrests in Marion

The FBI lists Marion with an arrest reporting agency of its own, filed as Marion Police Department. It reported 262 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 Linn County Sheriff's Office is the county agency. It reported 338 arrests for 2025.

The FBI's agency list also places one more agency in Linn County: Eastern Iowa Airport Public Safety (other).

How Many Arrests Marion 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.

• Marion: 262 for 2025, 340 for 2023, 820 for 2022, 929 for 2021, 817 for 2020 and 1,098 for 2019; 2024 is missing months.

Booking: Where People Arrested in Marion Are Held

The county jail is where a person arrested in Marion 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 380 people, down from about 390 in 2019. Its rated capacity in 2023 was 401 beds, and it ran at 94 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 Marion

For Marion the place to look is the case index of the Iowa District Court for Linn County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at iowacourts.gov/iowa-courts/district-court/judicial-district-6/distr..., phone 319-398-3411).

Statewide, Iowa Courts Online is the Iowa Judicial Branch's free statewide case search.

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 Marion

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.
