Polk County Sheriff and Criminal Records

The Polk County Sheriff's Office serves as the main law enforcement agency across the county and operates the county jail in Crookston. It works alongside city police departments in Crookston, East Grand Forks, and other communities. The Sheriff's Office is involved in the first step of most criminal cases, from initial arrest through booking. Contact information and county services can be found at co.polk.mn.us.

Under Minn. Stat. § 13.82, arrest data in Polk County is public government data. The Sheriff's Office and all other county law enforcement agencies must release the time and date of each arrest, the charges, the identity of the person arrested, and their custody status. Active investigations are kept confidential until the case closes or the statute of limitations runs. After that, inactive investigative data generally becomes accessible. The Sheriff's jail records are part of this broader public data framework.

Polk County is also close to the North Dakota border, and cases involving activity near East Grand Forks or the Red River may touch both state systems. The Minnesota DOC offender locator at coms.doc.state.mn.us only covers Minnesota state sentences. North Dakota cases would need to be searched through North Dakota's court system separately.

Criminal Background Checks

The BCA's CHS system is Minnesota's official tool for public conviction checks. At $8 per search, it returns public conviction data for anyone with a Minnesota conviction on file. The data covers felonies, gross misdemeanors, and misdemeanors. Under Minn. Stat. § 13.87, only convictions within 15 years of sentence discharge are public. Arrests that did not lead to a conviction are private and not included.

Law enforcement agencies and certain authorized government users access a broader data network under Minn. Stat. § 299C.46. This network includes warrant data, protection orders, and full criminal history beyond the public window. Polk County law enforcement uses this network for investigations and case management. Ordinary public searches go through CHS and MCRO.

Note: The BCA search covers all Minnesota counties, so a Polk County conviction will appear the same way as one from Hennepin or Ramsey County.

Expungement in Polk County

Minnesota's automatic expungement system under Minn. Stat. § 609A.015 means many people in Polk County may qualify to have records sealed without filing a petition. The BCA identifies eligible records annually. Qualifying cases include dismissed charges, completed diversions, and convictions after the required waiting period has passed. When automatic expungement applies, the BCA notifies the judicial branch and affected agencies, and the record is sealed 60 days later.

Cases that do not qualify for automatic expungement can be addressed through a petition under Minn. Stat. § 609A.03. You file in Polk County District Court in Crookston, serve all relevant agencies including the prosecutor and the BCA, and attend a hearing at least 60 days after service. The judge considers the seriousness of the offense, your rehabilitation, and the potential impact on public safety. A successful petition results in the record being sealed from public view, though law enforcement retains access.

Polk County residents convicted of qualifying offenses must register as predatory offenders under Minn. Stat. § 243.166.

Registrants verify their address in person once a year during their birth month and must report any change of address within five days.

Risk levels are determined under Minn. Stat. § 244.052. Level III offenders are publicly listed on the DOC website. Level I and Level II offenders are tracked internally but not published online. Polk County residents can search for Level III offenders in their area through the DOC at mn.gov/doc.
