One mark per person, by the year they died. Choose the box at the side to see every decade. Coverage is uneven: recent deaths come mostly from local news since 2000, older ones from official lists and historical newspapers, so the shape shows what was recorded as much as how many people died.
The Department of Corrections' Committee on Inmate/Youth Deaths reviews every death in a state prison or youth facility. Department policy requires it to write a yearly report of the deaths it reviewed and to make that report available to outside agencies on request.3 When someone dies in a prison, the facility calls the coroner or medical examiner and reports the death to law enforcement;5 the department does not tell the public right away, and gives few details.2 Its press releases have announced only a handful of deaths.6
County jails are run by sheriffs. Under the state jail rule, chapter DOC 350 of the administrative code, a sheriff must notify the Department of Corrections in writing within 48 hours after anyone dies in the jail, and must notify the next of kin as soon as possible.7 The department publishes nothing from these notices.
Wisconsin has no law requiring deaths in custody to be reported to one state agency. For the federal Death in Custody Reporting Act, the Department of Justice's Bureau of Justice Information and Analysis uses its authority to collect use-of-force data. County jails and police agencies report each month through an electronic form, and the Department of Corrections sends the bureau its own deaths, including those in juvenile facilities.4 The deaths reported by police and jails appear on the department's Use-of-Force and Arrest-Related Death dashboard.48 When a death results directly from an officer's action or failure to act, state law requires at least two investigators from an outside agency; their report is released only if the district attorney decides not to prosecute.9 In Milwaukee County, at least ten people died in the sheriff's custody from June 2022 to August 2026; the Waukesha County Sheriff's Office investigated the latest.10
U.S. Immigration and Customs Enforcement holds people in the Kenosha County and Dodge County jails, under agreements the counties signed with the U.S. Marshals Service.11 ICE publishes a report on each death in its custody.12 Its list of deaths from 2003 through 2017 includes none in Wisconsin.13
The release dashboard shows 1,212 deaths from 2000 through 2025, from 25 in 2010 to 72 in 2020.21 Its figures are close to, but not the same as, those the state gave the U.S. Bureau of Justice Statistics: for 2001, for example, the dashboard shows 44 deaths and the federal tables 48.22 Because the dashboard counts releases, a person who dies while held on a supervision hold is missing from it, as one was in 2023.2
For jails there is no state count. The Bureau of Justice Statistics recorded 161 deaths in Wisconsin's local jails from 2008 through 2018.23 The sheriffs' 48-hour notices to the Department of Corrections would give a full count, but they are not published.7
None of these sources names the people who died. Names reach the public through news reports, court cases and the rare press release.26
