Which system is holding them?

There is no single search that covers everyone in Nantucket County. Match the situation to the right official locator — most families start with the first one.

If the arrest was recent

Start with the local jail

For a recent local arrest, check the arresting jurisdiction’s official jail roster or custody-notification service. Housing may be at a municipal, county, regional, or contracted facility. If no record appears, ask the arresting agency or jail how to confirm the booking; do not infer the destination from distance or a facility listing.

General Nantucket Sheriff assistance for local holding or transfer questions. Nantucket has no county jail; people committed to county correctional custody use Barnstable. Ask the arresting police agency about initial holding before any transfer.

If nothing appears, contact the arresting agency or the responsible jail to ask how to confirm booking. A missing record does not prove release, and an agency may limit what it can disclose.

If they were sentenced to prison

Use the correctional locator

For a state-prison sentence, use the Massachusetts correctional locator. A short jail sentence may still be served in a local or regional jail. A sentence alone does not establish the housing location; confirm with the responsible agency.

If the charge is federal

Search the Federal Bureau of Prisons

A federal charge does not tell you which building holds the person. The U.S. Marshals Service is responsible for federal pretrial detention and may use local, state, private, or federal facilities. Check the Federal Bureau of Prisons locator, but a missing result does not establish that the person is not detained. For a recent federal arrest, contact the arresting agency or the relevant U.S. Marshals district office to ask about the appropriate custody-information process. USMS is a contact route, not a public person locator, and disclosure of a location is not guaranteed.
