Drones have been added to the Crime Scene Unit and are deployed to motor vehicle crashes, crime scenes as well as to assist other agencies in their investigations. In 2019 two deputies were certified as drone pilots. Currently the Crime Scene Unit has two drones, one with a FLIR thermal imaging system and placed in service in 2019.
