Which Agency Holds a Report from Marathon 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 Marathon County that is the Marathon 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 Marshfield Police Department and the Colby-Abbotsford Police Department are each listed by the FBI across several counties including Marathon County, so their arrests are not broken out for Marathon County here.
