Finding Someone in Custody in Jamestown
A person kept in custody after an arrest in Jamestown is held at the county jail, run by the Chautauqua County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Chautauqua County Sheriff's Office at sheriff.us/corrections (page title: Corrections), which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster.

A sentence of more than a year is served in state prison, not the jail; the New York State Department of Corrections and Community Supervision lists its inmates at nysdoccslookup.doccs.ny.gov.
