Finding Someone in Custody in Laramie County
A person kept in custody after an arrest in Laramie County is held at the county jail, run by the Laramie County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Laramie County Sheriff's Office at laramiecountywy.gov/County-Government/Elected-Officials/Laramie-Cou... (page title: Laramie County Sheriff's Office | Laramie County, Wyoming), phone 307-633-4700, Monday - Thursday 8:00 am - 5:00 pm, which answered when SearchSystems opened it on September 27, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 307-633-4700.
