Notes on the record
- The county's own site hosts an 'Inmate Locator' at co.trempealeau.wi.us/.../inmate_locator/index.php, described as a daily listing of individuals in custody, which is on the office's own domain and was counted toward the roster check (a separate ch.co.trempealeau.wi.us/inmatelocator/ subdomain also exists but was not separately verified).
- The jail page states a PREA information / sexual-assault-and-harassment-prevention guide is provided to inmates, satisfying the prea check.
- No capacity/bed count, budget, death records, inspection reports, contracts, bond information, or fee schedule were found published on co.trempealeau.wi.us.
These three offices decide who sits in a cell in Trempealeau 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).
