Notes on the record
- Custer County's own domain (custercountysd.com) could not be fetched this session — attempts returned provenance refusals because no WebSearch call was spent on Custer County within the group's hard cap of 5. Recorded honestly as 'not found' rather than guessed.
- South Dakota has no state agency that inspects adult county jails. See the state-layer entry in plains_states.json.
- Not found — custercountysd.com could not be reached this session (refused for lack of search provenance; the group's 5-search budget was exhausted on other counties before a dedicated Custer County search could be run).
These three offices decide who sits in a cell in Custer 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.
