Marshall County, Iowa, has about 40,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Marshall County depends on where the incident happened: the Marshall County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Iowa Open Records Law (Chapter 22) requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Marshall County
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
In Marshall County that is the Marshall County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
Reports from the Marshall County Sheriff's Office
The Marshall County Sheriff's Office is the county agency; it reported 382 arrests for 2021.
Its reports come from its records unit. The office's page SearchSystems verified is its custody page, at sheriffmarshallcounty.org/current-inmate-roster (page title: Private Site), which answered when SearchSystems opened it on October 9, 2026.
Reports from the City Agencies in Marshall County
The two cities the FBI lists in Marshall County with a reporting agency of their own, with the police records page SearchSystems verified where the city has a guide:
- Marshalltown: 127 violent and 547 property crimes reported for 2023; 902 arrests reported for 2025. The Marshalltown police records page is at marshalltown-ia.gov/305/Police-Records, phone 641-754-5750 (verified September 26, 2026).

What the Iowa Open Records Law (Chapter 22) Requires
The Iowa Open Records Law (Chapter 22) sets the rules: an answer without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, at a charge of the actual cost of copying and retrieval, from the agency that holds the report.
