The County Commissioners
They pay for the jail. The sheriff runs it.

Notes on the record
- The four district judges serve the whole 6th Judicial District — Campbell, Crook and Weston counties — not Campbell alone.
- Capacity and population figures exist only in archived annual reports from 2007–09. The live page publishes neither.
- The roster credit is for a VINE lookup link, not a roster the county publishes.
- The commission's agendas and minutes are moving to a third-party portal (CivicClerk); other county boards remain on the older system.
These three offices decide who sits in a cell in Campbell 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).
