This guide names each agency, where its records page is and what the Iowa Open Records Law (Chapter 22) requires of it.

Which Agency Holds a Report from Sioux County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Sioux County that is the Sioux 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.
The Sheldon Police Department is listed by the FBI across two counties including Sioux County, so its arrests are not broken out for Sioux County here.
