The Minnesota Criminal History and Your Own Copy
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. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a request to the Bureau of Criminal Apprehension. The state page SearchSystems verified for it is at dps.mn.gov/divisions/bca/bca-divisions/criminal-justice-information....
