Divisions
Missoula County Sheriff’s Office (MCSO) performs a variety of public safety and administrative tasks in their service to the communities within the boundaries of Missoula County. To provide the most comprehensive service available, MCSO has a variety of divisions and units:
The Sheriff's Office has an Administrative Captain (AC), assisted by an Administrative Lieutenant, who works on finding, applying for and administering grants. The AC administers the budget, coordinates external hiring and internal promotions, as well as managing the Sheriff's Office fleet and special teams.
In addition to serving as Chief Deputy Coroner, the Administrative Captain and Lieutenant oversee several units and special teams. These include the K-9 Units, Special Response Team (SRT), the Reserve Deputy Unit, Civil Deputies, School Resource Officers, Missoula County Sheriff's Office Cadets, and Bailiffs and Special Security Officers.

The detectives investigate property crimes (vandalism, theft, and burglary), crimes against people (assaults, rapes, homicide), warrants and narcotics.
The Cold Case Unit operates within the Detective Division and our special deputies work tirelessly on those cases where, at the time, no new evidence was available to solve the case.
The Missoula County Detention Facility (MCDF) opened on Nov. 1, 1999, replacing the overcrowded and outdated facility on the fourth floor of the courthouse annex.
The facility has two main components: a juvenile detention facility and a county adult detention facility. The total capacity of both components is 394. Click here to learn more.
