The Criminal Investigations Division, or CID, is responsible for conducting all criminal investigations in the jurisdictions in which the Sherburne County Sheriff's Office is the primary law enforcement service provider. CID offers a wide array of investigative services to Sherburne County. Contained within CID are a number of different units: General Investigations, Jail Investigations, School Liaison Officers, Crime Scene Team, Computer Forensics & Crime Analysis, Financial Crimes and Welfare Fraud, Health and Human Service Investigations, as well as the Drug Task Force.
Investigators involved with general investigations follow up on reports generated by patrol deputies including the interviewing of witnesses and suspects on various calls for service.
