The Investigations Unit is responsible for the investigation of serious crimes that occur in Crow Wing County. As a reflection of the increasingly complex nature of police work the investigators have become more specialized in their duties. The Investigations Unit consists of 2 units: General Investigations and the Lakes Area Drug Investigative Division (LADID). 

General Investigations

General Investigations are responsible for working directly with the patrol deputies in following up and assisting in the investigations, as well as investigating their own cases assigned to them. Examples include homicides, major assaults, sexual assaults, aggravated assaults, child protection cases, burglaries, thefts, financial crimes, welfare fraud and computer crimes. Investigators are also responsible for processing crime scenes as well as evidence identification and preservation. Investigators also work closely with other agencies within Crow Wing County to include Social Services, Probation and the County Attorney's Office.

Lakes Area Drug Investigative Division (LADID)

LADID consists of narcotics investigators from the Crow Wing County Sheriff's Office, the Brainerd Police Department and the Baxter Police Department. LADID investigators conduct investigations into the illegal sale, possession, manufacturing, distribution and use of narcotics in Crow Wing County. They work in close cooperation with other local, state, and federal drug units in their effort to detect and apprehend drug offenders.
