Finding Someone in Custody in Kronenwetter
The county jail, run by the Marathon County Sheriff's Office, holds everyone kept in custody after an arrest in Kronenwetter, from every agency.
SearchSystems opened and checked the jail page of the Marathon County Sheriff's Office at marathoncounty.gov/about-us/departments/sheriff-s-office (page title: Sheriff's Office | Marathon County, WI), phone 715-261-1200, 500 Forest Street Wausau, WI 54403, which answered when SearchSystems opened it on October 9, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 715-261-1200.
