Crash Reconstruction

The Dunn County Sheriff's Office has two deputies that have received specialized training in crash investigation and reconstruction. Vehicular accident reconstruction is the scientific process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists are employed to conduct in-depth collision analysis and reconstruction to identify the collision causation and contributing factors in different types of collisions, including the role of the driver(s), vehicle(s), roadway and the environment. The laws of physics and engineering principles such as the conservation of linear momentum, work-energy methods, and kinematics are the basis for these analysis and may make use of software to calculate useful quantities. The accident reconstruction provides rigorous analysis that an expert witness can present at trial. Accident reconstructions are done in cases involving fatalities, and often when personal injury is involved. Results from accident reconstructions are also useful in developing recommendations for making roads and highways safer, as well as improving safety aspects of motor vehicle designs. 


First Responder Program

The Dunn County First Responder Program is coordinated through the Sheriff's Office. This program consists of volunteers that respond to calls for emergency medical assistance. This program is run in part on donations from various organizations and community members.

This program has assisted law enforcement in saving many lives over the years it has been in existence.  If you are interested in becoming a first responder, please contact 715-231-2938.


Reserve Deputy Program

The Dunn County Reserve-Deputy Division consists of up to 30 reserve deputies. The reserves are supervised by reserve sergeants, and one reserve lieutenant. The unit is supervised by the Field Services Captain.  The reserve deputies work a variety of events throughout the county when contracted policing is required or for events that require extra police presence.  Some reserves that complete the field-training program can fill open patrol shifts due to deputy sick leave, vacation, or other absences.  Reserve deputies are certified, armed, and fully sworn deputies with arrest powers.



K-9 Unit

The Dunn County Sheriff's K-9 Unit consists of two specifically trained K-9's.  The K-9 unit services the Sheriff's Office and is available to other police agencies in Dunn County that request its assistance. K-9 officers undergo training to keep their skills sharp so they are ready when called for duty.


Jax is  a German Shepherd trained by the Saint Paul Police K-9 Training Program and is trained as a patrol dog capable of narcotics detection, person tracking, and criminal apprehension.  Chief is a bloodhound specially trained in person tracking of both suspects and also victims in search and rescue situations.

The Dunn County K-9 units also provide aid to other police agencies in West-Central Wisconsin that may request their assistance. To request Dunn County's K-9 assistance, please contact the Sheriff's Office Communications Center at 715-232-1348.

The DRE evaluates and assesses appearance and behavior. The DRE also carefully measures and records vital signs and makes precise observations of the person’s automatic responses and reactions. The DRE also administers carefully designed psychophysical tests to evaluate the person’s judgment, information processing ability, coordination and various other characteristics. The DRE will systematically consider everything about the person that could indicate the influence of drugs.

DREs generally deal with cases relating to persons that are suspected of driving under the influence of drugs but also may assist on any criminal case where it may be necessary to determine if there is drug impairment. DREs also may be used when responding to certain medical calls and are proven useful to determine if illicit or prescription drug abuse is related to the medical problem. They can often times provide valuable information to responding medical professionals to help the patient. DREs also are a community resource to school liason officers, school officials, and parents if an issue arises where a student may be suspected of using drugs.

The Dunn County Sheriff's Office will assist area law enforcement agencies that may need a Drug Recognition Expert (DRE) to respond to their jurisdiction.  The Wisconsin DOT funds any out-of-county service calls.

ICAC (Internet Crimes Against Children)

The OJJDP's (Office of Juvenile Justice & Delinquency Prevention) Internet Crimes Against Children Task Force Program (ICAC program) helps state and local law enforcement agencies develop an effective response to cyber enticement and child pornography cases. This help encompasses forensic and investigative components, training and technical assistance, victim services, and community education. 

The program was developed in response to the increasing number of children and teenagers using the Internet, the proliferation of child pornography, and heightened online activity by predators seeking unsupervised contact with potential underage victims.


The Dunn County Sheriff's Office has three deputies that received specialized training to properly investigate these types of cases.  Since the ICAC program's inception in 1998, more than 288,000 law enforcement officers, prosecutors, and other professionals have been trained in the United States and in 17 countries on techniques to investigate and prosecute ICAC related cases.

When deputies are not busy with calls for service or other duties, they are responsible for proactive enforcement of state law and county ordinances. Proactive enforcement includes business checks during non-business hours; including nights and weekends, extra patrol in villages and communities, apprehension of criminals and traffic violators, bar checks and alcohol enforcement, special details, and much more.


A large part of the patrol division's time is spent in traffic enforcement. In addition to speed enforcement, officers are always on the lookout for other traffic violators, such as stop sign/stop light violators, vehicle equipment violations, improper registration and/or driver's licenses, OMVWI, and drug enforcement.  Patrol squads are equipped with radar units capable of checking the speeds of target vehicles within range. Pictured right, a deputy enforces speed along the eastbound lanes of STH 29. Deputies also have other ways of checking speed, such as the use of Laser or special aircraft details.


Patrol deputies are almost always the first to respond to emergency scenes. Therefore, they must be equipped with many different types of equipment to handle various types of police emergencies.  All squads are equipped with mobile radios which utilize a state-of-the-art digitally trunked radio infrastructure throughout Dunn County.  When squads leave Dunn County, their mobile radios automatically connect to a statewide system of radio towers allowing for communication from anywhere in the state.  Squads also have high definition digital camera systems, cellular phones, AED units, oxygen, and first aid supplies.  Through a technology grant in 2010, all squads had new and upgraded computers installed.  These computers allow officers to be more efficient with their duties by completing traffic warnings, citations, and crash reports much quicker and with much less chance of error. The computers also allow an officer to query a driver's license and vehicle registration status, warrant inquiry, and communicate with other officers in real-time throughout the county. Officers also receive CAD (Computer Assisted Dispatch) information through the computer in real-time while at service calls or completing computerized reports. Deputies also save time spent in the office by completing police reports in the field and submitting them electronically.  All squads are tracked via GPS which keeps emergency dispatch personnel updated on each squad's position and activity in the county.

Deputies always need to be prepared for emergency calls such as shootings that require a tactical response. In 2014 there were four officer-involved shootings in Dunn County.  In addition, officers respond to numerous calls throughout the year that require a tactical approach for the safety of deputies and the public.  All deputies carry tactical response uniforms and gear that allow them to quickly respond to these dangerous calls at any moment.  There are also a few patrol deputies that are members of the Eau Claire Regional SWAT team, a regionally organized and specially trained unit for serious matters that require a tactical response.

Criminal Investigations Unit


​​The Criminal Investigation Unit consists of four specially trained investigators, one of which is the Investigative Sergeant who oversees the unit. Each investigator is a trained professional that is dedicated to solving crime and serving the residents of Dunn County.

There are many specialties within the Criminal Investigation Unit. Some of which include death investigations, internet crimes, property crimes, drug enforcement, crimes involving children and white collar crimes. Investigators receive specialized training to assist in their responsibilities.  Investigators also take over cases from the patrol unit that patrol deputies cannot complete within their shift, or finish cases that require response out of the county into neighboring jurisdiction.  This keeps patrol deputies free for upcoming shifts so they are ready to respond to new service calls.


If you have information that would help us prevent or solve a crime, you can help. Please visit the Dunn County CRIME STOPPERS website. Click the banner below for more information. You may remain anonymous if you wish.

DRE (Drug Recognition Expert) Program

A drug recognition expert or drug recognition evaluator (DRE) is a police officer trained to recognize impairment in drivers under the influence of drugs other than, or in addition to, alcohol. The International Association of Chiefs of Police (IACP) coordinates the International Drug Evaluation and Classification (DEC) Program with support from the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation.


The Dunn County Sheriff's Office currently has one deputy trained as a Drug Recognition Expert. There are approximately 130 certified DREs in the State of Wisconsin. The DRE is often times utilized by other Dunn County deputies and is also asked to assist other area police agencies in some cases. The Dunn County Sheriff's Office DRE program is funded by the Wisconsin Department of Transportation.

DREs undergo approximately 74 hours of classroom training and 40-60 hours of field training with drugs. The training is extensive and detailed. DREs must undergo recertification training annually and keep up-to-date with related training or they lose their certification and "expert" status.

Project Lifesaver Program

The Dunn County Sheriff's Office became part of the International Project Lifesaver Program in the fall of 2013.  We have four deputies that received specialized training by Project Lifesaver and those deputies are now certified to teach other officers of the department how to run the program.  Our agency was able to purchase the Project Lifesaver locating equipment after being awarded a grant for the program.


The primary mission of Project Lifesaver is to provide timely response to save lives and reduce potential injury to children and adults who wander due to Alzheimer’s, autism, and other related conditions or disorders.

The task of searching for wandering or lost individuals with Alzheimer’s, autism, Down syndrome, dementia or other cognitive conditions is a growing and serious responsibility. Without effective procedures and equipment, searches can involve multiple agencies, hundreds of officers, countless man hours and thousands of dollars. More importantly, because time is of the essence, every minute lost increases the risk of a tragic outcome.

Working hand in hand with trained public safety agencies, Project Lifesaver International (PLI) will help you save time, money and most importantly, your loved ones.
