Notes on the record

The Sheriff's Department site (kewauneesheriff.org) lists a 'Policies' page containing only a Use of Force policy (2021) and a Citizen Complaints policy (2020) — no PREA policy is published there.
A separate county government domain (kewauneeco.org) also has a Sheriff department page; the department's own kewauneesheriff.org site was used as the primary source here since it carries the fuller set of jail-related pages.
State inspection/oversight: Wisconsin county jails are subject to inspection by the WI Department of Corrections, Division of Community Corrections, under Wis. Admin. Code DOC 350; no county-specific inspection report was found on the Kewaunee County site.

These three offices decide who sits in a cell in Kewaunee County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).

How much is your sheriff — and your judge — costing you?

Your VOTE is POWERFUL.

The sheriff who runs this jail is elected. So are the commissioners who pay for it.
