How to Find Out About an Arrest in Sweet Grass County
An arrest in Sweet Grass County can be traced in two places, depending on where the case stands: the case index of the Sweet Grass County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at sgcountymt.gov/government-departments/county-govt/clerk-of-district..., phone 406-932-5154); the County Attorney, which decides whether an arrest becomes a charge (its page is at sgcountymt.gov/government-departments/county-govt/county-attorney, phone 406-932-4376).
Montana is one of the states that lets anyone look up another person's statewide criminal history: the CHOPRS service lets anyone search public criminal history online by name, through the Montana Department of Justice. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
