Finding Someone in Custody in Alamogordo
The county jail, run by the Otero County Sheriff's Office, holds everyone kept in custody after an arrest in Alamogordo, from every agency.
SearchSystems opened and checked the jail page of the Otero County Sheriff's Office at co.otero.nm.us/300/Information-for-Inmates (page title: Information for Inmates | Otero County, NM), which answered when SearchSystems opened it on September 24, 2026.
That page is the office's jail information page rather than a roster.
