Finding Someone in Custody in Grafton County
A person kept in custody after an arrest in Grafton County is held at the county jail, run by the Grafton County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Grafton County Sheriff's Office at graftoncountysheriff.net (page title: Grafton County Sheriff's Office), which answered when SearchSystems opened it on September 24, 2026.
That page is the office's jail information page rather than a roster.
