Montana Department of Justice, MT Police Jobs


Billings, Montana 


This is a Criminal Investigator position in the Major Case Section which coordinates investigations and conducts criminal investigations with city, county, state and federal law enforcement agencies at their request.

The section also coordinates and conducts criminal investigations of allegations referred by the Montana State Fund and the Motor Vehicle Division of the Department of Justice.

These investigations include—but are not limited to—homicide and other violent crimes, in-custody assaults and deaths including officer-involved shooting events and critical incidents, organized crime activity, white-collar crime, sex crimes, corruption, official misconduct, theft, complex financial crimes, and internal agency investigations.

Criminal Investigators (Agents) respond to callouts, process crime scenes and collect evidence, conduct field interviews/interrogations, complete follow-up investigative work to build a case file, assist prosecutors and testify in court.

Major Case Agents also provide training to law enforcement agencies and public safety sectors throughout the state.

This is a modified position, meaning it is funded for a specified term.

The funding has been approved up through December 31, 2024, with the expectation that funding will be requested again at the end of this time period.

Though expectations point toward renewed funding, modified positions are always subject to funding availability and the position could terminate at the end of the cycle if appropriations are not available.

This position, though subject to travel in support of statewide criminal investigations, will be dedicated to investigations and enforcement of major case incidents and violent crime occurring in the Billings and Yellowstone County regions.

An emphasis will be placed on assignments and caseloads occurring within that jurisdiction.
