How to Find Out About an Arrest in Mahnomen County
An arrest in Mahnomen County can be traced in two places, depending on where the case stands: Minnesota Court Records Online, the Minnesota Judicial Branch's free statewide case search, which shows whether charges were filed; the County Attorney, which decides whether an arrest becomes a charge (its page is at mahnomencounty.gov/department/departments_a_h/attorney/index.php, phone 218-935-2378).
Minnesota is one of the states that lets anyone look up another person's statewide criminal history: the public criminal history search online is free and shows 15 years of convictions, through the Minnesota Bureau of Criminal Apprehension. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Mahnomen County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Minnesota Government Data Practices Act the agency must answer promptly, within a reasonable time, and it may charge copying, and staff time for requests over 100 pages.
