Jurisdiction depends on the location of the incident and the people involved.
Cass County is part of the 9th Judicial District. All criminal and civil cases filed in Cass County run through the 9th District court. If you want to check court case outcomes, the Minnesota Courts Records Online system is the place to start, and is covered in detail below.
Requesting Police Records in Cass County
Under Minn. Stat. 13.03, any person in Minnesota has the right to inspect public government data at no cost. Copies cost $0.25 per page for the first 100 pages. You do not need to provide a reason for your request. The agency must respond in a reasonable time and must cite a specific law if it denies access to any record. A vague privacy claim without a statutory citation is not a valid denial.
To request Cass County police records, contact the sheriff's office through the county website at www.co.cass.mn.us/departments/sheriffs-office for current contact details. Written requests by mail to the Walker office should state the type of record, the date range, and any case number or name that will help staff find the file. If you have an incident number or case number, include it. Clear, specific requests are filled faster than open-ended ones.
Note: Active investigation records are classified under Minnesota law until the case is closed. Once a case is resolved, most records become public. The agency must tell you if this exception applies to your request.
If you need records about yourself, you may have access to additional private data beyond what the public can access. The data rights section below explains your rights as a data subject under Minnesota law. Cass County agencies must follow the same rules as every other government body in the state.
What Cass County Police Records Are Available
The screenshot below shows the Minnesota BCA background check portal, which covers statewide criminal history records including those from Cass County.
Visit dps.mn.gov/divisions/bca/Pages/background-checks.aspx for BCA background check options covering all Minnesota counties, including Cass.
Minn. Stat. 13.82 is the primary law governing what law enforcement data is public in Minnesota. From the time of arrest, these data points are public: the name, age, sex, and address of the person arrested; the alleged offense or charge; the date, time, and place of the arrest; and the name of the arresting agency. Anyone can access this data. No court order is required, and you do not need to show a reason for asking.
Incident reports from calls for service may also be public, depending on the status of the case. Booking photos are public in Minnesota. 911 call transcripts are generally public, but 911 audio recordings are private. Data about active criminal investigations is classified until the case closes. Victim information in sensitive cases may be redacted before records are provided. The agency will note any redactions and identify the law that permits them.
For incidents involving Leech Lake tribal members or occurring on reservation land, tribal records may be held separately. Both the county sheriff and tribal police may have relevant records depending on the specifics of the case. If you are not sure which agency to contact, start with the county sheriff and ask if tribal jurisdiction may apply.
Minnesota Court Records Online: MCRO
The screenshot below shows the Minnesota Courts Records Online (MCRO) portal, where you can search court cases from Cass County and all other Minnesota judicial districts.
MCRO at publicaccess.courts.state.mn.us is free and lets you search Cass County court case data by name or case number.
MCRO covers cases filed in the 9th Judicial District, which includes Cass County. Search by name or case number to see filed charges, hearing dates, and case outcomes. If you want to check whether a Cass County arrest led to criminal charges and what the result was, MCRO is the place to start. The system is free and accessible at any time.
MCRO does not show contacts that did not result in a court filing. Arrests not followed by charges, or calls for service that closed without a case, will not show up in MCRO. For the most complete picture, check both the sheriff's records and MCRO together. The Cass County courthouse in Walker handles case files for the 9th District. Court staff can help you search in person during business hours.
BCA Criminal History Checks
For formal statewide criminal history searches, the Minnesota Bureau of Criminal Apprehension (BCA) is the right agency. The BCA can be reached at 651-793-2400, option 7. Their background check portal is at dps.mn.gov/divisions/bca/Pages/background-checks.aspx. The BCA covers records from all 87 Minnesota counties, including Cass.
Under Minn. Stat. 13.87, most BCA criminal history data is private except for people currently in the criminal justice system. A public criminal history tool exists but gives limited results. Full certified records require a formal process with fees. For a quick check on court history, MCRO is easier and free. For comprehensive statewide criminal history, the BCA formal process is the right choice.
Data Access Rights in Cass County
Minnesota's Government Data Practices Act, found at Minn. Stat. 13.025, makes all government data public by default. Any data held by a Cass County agency is public unless a specific law says otherwise. The agency must justify any refusal with a legal citation. You do not need to justify your request. This is a fundamental rule that applies to every county and city in Minnesota.
Under Minn. Stat. 13.04, if you want to inspect data that any government agency holds about you, you have that right. You can contest data you believe is incorrect within 30 days of learning about it. Appeals must be filed within 60 days. These rights apply to Cass County Sheriff records, court data, or any other county agency data about you.
Note: If a Cass County agency denies a records request without citing a specific statute, you can contact the Minnesota Department of Administration's Information Policy Analysis Division to file a complaint or get guidance.
Agencies are expected to handle data requests in a reasonable time. For most simple requests, a response within a few business days is standard. Larger or more complex requests may take longer. If you have not heard back in a reasonable time, follow up with the agency to ask about the status of your request.
