The Investigations Division is under the supervision of the Investigations Captain and is comprised of seven detectives who investigate felonies against persons/children to include homicide, sexual assault, Internet Crimes Against Children (ICAC), aggravated assaults and assaults with weapons. Detectives also investigate property crimes to include burglary, theft, motor vehicle theft, and criminal drug offenses. Detectives are available 24/7 to assist the Patrol Division.


The Investigations Division is responsible for: 

  • Identifying, locating, interviewing, and arresting criminal suspects
  • Locating and interviewing victims and witnesses
  • Locating, identifying, and preserving physical evidence
  • Presenting criminal cases to the County Attorney for prosecution
  • Recovering stolen property

Internet Crimes Against Children (ICAC) Taskforce

The Investigations Division is affiliated with the Montana Internet Crimes Against Children Taskforce. ICAC investigations include persons using the internet to attempt to engage in sexual contact with underage children and persons who download, manufacture, and/or distribute images of child pornography. The Montana ICAC Taskforce provides our investigators with the ability to conduct both reactive and proactive investigations of internet crimes against children with the goal of arresting suspects before they have victimized a child.

The ICAC Task Force was created to help local law enforcement agencies develop an effective response to technology facilitated child sexual exploitation and internet crimes against children. The ICAC Task Force Program was developed in 1998. Since then there are 61 taskforces of 5230 federal, state, and local law enforcement and prosecutorial agencies throughout all 50 states. The ICAC Task Force Program funding is supported under the Missing and Exploited Children appropriation included in the Department of Justice fiscal year appropriation.

Case Assignment

Patrol Officers respond to crimes reported to our department. The initial Officers conduct an investigation which may include interviewing victims, witnesses, and suspects. Officers also collect physical evidence when possible. All reports are reviewed by the Investigations supervisors. Cases are assigned to a detective based on solvability variables. Detectives assigned to a case will continue the investigation. Any reports not assigned to a detective will be investigated by the initial responding Officer.

Crime Prevention Officer

The crime prevention officer (CPO) is under the supervision of the Investigations Captain. The CPO works with the community and community groups to promote public safety and to offer training to the public as it relates to public safety. The CPO provides an avenue for citizens to provide information to the law enforcement department regarding crimes and criminal activity. The CPO works very closely with the case detectives to ensure that information received from the community is provided to the detective assigned to work the crime.
