Major Investigations Unit

Working Together

This team of selected officers from Butler PD, Chenequa PD, Delafield PD, Elm Grove PD, Hartland PD, Summit PD, Pewaukee PD, and Waukesha County Sheriff Dept. are trained and prepared to investigate all major crimes and traffic accidents that may occur in any of these jurisdictions.

This is a significant mutual aid agreement that allocates the necessary resources to investigate these major incidents, yet also allows each community to maintain police coverage for other types of activities. The sharing of expertise and equipment makes this team cost-effective and provides a professional quality of investigative efforts.
