If the arrest was recent
Start with the county jail
In Maine, someone who was just arrested and not released is held in the COUNTY JAIL run by the county sheriff (for example, the Cumberland County Jail in Portland is the state's largest), not in a state prison, so the DOC search will not show a brand-new pretrial arrest.
Maine historically did NOT participate in the national VINE custody system; a limited pilot began in 2025 in only a few counties and a regional jail, so VINE is not yet a reliable statewide tool here.
The dependable path is to contact the county jail directly: many sheriff's offices post an online jail roster, and booking/records staff can confirm whether someone is in custody, the booking date, and the bail amount.
Maine county jail rosters are fragmented and run separately by each county sheriff. Check the sheriff's website for the county where the arrest happened for an online roster, or call the jail's booking/records line. VINE coverage in Maine is only a recent, limited pilot, so do not rely on it statewide.
Maine is not covered by VINELink — use the arresting county sheriff’s jail roster or call the jail’s booking or records line.
