Montana inmate search: county jail or state prison.
A county jail holds people who were just booked, are waiting for court or are serving a short sentence; the Montana Department of Corrections holds people serving a sentence after conviction, and both are in the search. Federal custody is a third system, also in the search. A result names the facility, so one name search says which of the three holds the person, or that none we can see does.
