Law Enforcement Services
The Sheriff's Office provides law enforcement services throughout Polk County. The Sheriff's Office is the responsible agency for unincorporated Polk County, the cities of Alleman, Bondurant, Elkhart, Grimes, the U.S Army Corps of Engineers at Saylorville Lake and the Polk County Courthouse.
The Sheriff's Patrol Division is the backbone of the law enforcement component of the Sheriff's Office. Patrol Deputies are the first responders to all major crimes and other emergencies. It is the responsibility of the Patrol Division to respond to every type of call for service from a barking dog to a fatal motor vehicle accident or homicide scene. Patrol Deputies respond to and assist the public in these and many other types of volatile situations.
The Criminal Investigation Division (CID) investigates crimes committed in Polk County and our contract cities that are reported to the Patrol Division and directly from victims. Crimes investigated by CID include Homicides, Property Crimes, Theft, Burglaries, Arson, Forgery, Criminal Mischief, crimes committed against children, physical and sexual abuse and missing persons. Detectives obtain evidence, interview victims/witnesses, determine suspects and evaluate cases for prosecution. Their duties also include evaluating crime trends and recovering stolen items. In addition, CID has two trained polygraph examiners and two detectives trained as crime scene investigators.
