Department Overview
The Warrenville Police Department is a full-service, professional, municipal law enforcement agency. Officers of the Department are trained and equipped to handle the full spectrum of law enforcement responsibilities from routine calls for service, to complex criminal investigations. Warrenville Police Officers patrol City streets 24 hours per day, 365 days per year and are always available to serve. Anyone needing police assistance should dial 9-1-1, and an officer will be dispatched to the location. No one has to give personal information when reporting criminal or suspicious activity.
When calling from a cellular phone, the 9-1-1 call may not be answered by the City’s dispatch center (DUCOMM), but rather the DuPage County Sheriff’s Office. This occurs because cellular calls are often routed to the largest law enforcement agency in the area. Because a cellular 9-1-1 call may be answered by the Sheriff’s Department, response times may be lengthened.
Department Leadership Philosophy
The Warrenville Police Department practices a community oriented leadership philosophy that requires all members of the Police Department to be involved in identifying areas of concern regarding public safety. Police Officers and the community work together to address quality of life issues and order-maintenance. The goal is to identify and address potential problems before they affect residents.
Department Organization
The Police Department employs 31 sworn full-time officers, 4 sworn part-time officers, and 8 civilian employees. The Department is organized under two divisions, each headed by a Deputy Chief of Police. The Deputy Chief of Operations is responsible for the Patrol and Detective Divisions, and the Deputy Chief of Adminstration and Support Services is responsible for the administrative operations of the Department including the CSO/Animal Control and Records Division. The Chief of Police is responsible for the oversight, direction, and day-to-day operations of the Police Department.
Patrol Division
The Patrol Division consists of four uniformed patrol teams. Each team, supervised by a Sergeant and Corporal, respond to 9-1-1 calls for service, initiate investigations of crimes, conduct traffic enforcement, enforce City ordinances, and proactively maintain a visible presence, in order to deter crime.
Within each patrol team are highly trained Patrol Officers who have received advanced training as Forensic Evidence Technicians, Traffic Accident Investigators, Truck Enforcement Officers, K-9 Officer, and Juvenile Officers.
Forensic Evidence Technicians
This Unit consists of highly trained Police Officers who are able to identify and recover forensic evidence at crime scenes. The Police Department is trained and equipped to process crime scenes that run the gamut from vandalisms to homicides. This capability gives Warrenville Police Officers opportunities to link suspects to crimes through nearly irrefutable forensic evidence, such as fingerprints and DNA. Additionally, by processing every viable crime scene, the Police Department can collect and compare forensic evidence to reported crimes in an attempt to find a link, and develop a suspect or suspects.
It is said that a criminal offender always leaves, or takes physical evidence with them, from a crime scene. By having the right equipment and training, Police Officers can seek to identify and collect this evidence.
Additionally, Warrenville Police Forensic Evidence Technicians participate in the DuPage County Major Crimes Task Force, during major crimes call outs. The opportunity to work with DuPage County's best and most skilled Forensic Evidence Technicians allows Warrenville Officers the opportunity for gaining practical experience during major crimes investigations.
K-9 Unit
Corporal Matt Komar, and his K-9 partner “Bandit” patrol the streets of Warrenville and provide a tremendous resource to the Police Department. Bandit is a specially trained German shepherd who can detect drugs, conduct searches for people, conduct searches for articles, and search buildings for criminal suspects.
Bandit is a favorite with children in the community as he is a very friendly and sociable fellow; however, Bandit can be a formidable opponent when in pursuit of a dangerous, violent criminal suspect.
Animal Control
The Warrenville Police Department’s Animal Control Officer handles calls for sick and injured wildlife, and calls for stray domestic animals. They also investigate other complaints involving wildlife and domestic animals, such as animal cruelty, dog fighting, illegal trapping, and animal neglect. Animal-related calls are dispatched through the City’s 9-1-1 service. City dog tags are required for all dogs residing within City limits, and can be purchased at City Hall or the Police Department.
Investigations Division & Administrative Services
Investigations Division 
The Investigations Division of the Warrenville Police Department is responsible for all follow-up investigations. Detectives assigned to the Investigations Division are involved in all areas of criminal investigations including, crimes against persons, property crimes, financial crimes, financial identity theft, and juvenile offenses.
Detectives have received specialized training in criminal law, laws of search and seizure, major case investigations, forensic evidence interpretation, death investigations, sexual assaults, and juvenile offenses. Warrenville Detectives participate in the DuPage Major Crimes Task Force, a multi-jurisdictional task force that investigates homicides, attempted homicides, serial sexual assaults, and child abduction. Additionally, Warrenville Detectives participate in the investigations of cyber crimes, which often target young victims via the Internet.
Problem Oriented Policing Unit (POP Unit)
The Problem Oriented Policing Unit (POP Unit) is a specialized crime suppression unit of the Police Department. The Officers selected for this assignment are highly trained in drug enforcement, gang investigations, vice investigations, and issues affecting quality of life. POP Unit officers identify and aggressively enforce laws and ordinances in order to reduce crimes of opportunity and enhance the safety and security of citizens.
POP Unit officers also employ strategies to identify at risk youth and provide diversionary measures in an attempt to correct youthful offenders behavior. POP Unit officers are allowed to spend considerable amounts of time to problem solving, as they are not restricted to a geographical patrol zone.
Additionally, POP Unit officers engage in compliance checks at liquor and tobacco retailers throughout the City. The goals of these checks are to reduce the opportunity for underage individuals to acquire alcohol or tobacco products.
Administrative Services Division
Administrative Services Division personnel consist of Police Records Assistants and the Administrative Services Sergeant. Police Records Assistants are responsible for the processing and archiving all police documents generated by the Police Department. This responsibility is automated via a Records Management System (RMS) that is shared Countywide. RMS allows Officers to generate police reports from their patrol vehicles and wirelessly transmit those reports for supervisor approval and filing. RMS provides a useful tool for the storing and accessing case files and also information sharing with other police departments.
The Administrative Services Sergeant is responsible for the City’s red light photo enforcement program as well as serving as the administrative liaison for Warrenville Emergency Services Disaster Agency (ESDA). The Sergeant provides direct supervision for the Police Records Assistants, and maintains the National Incident Management System (NIMS) procedures, which is required by the Federal Emergency Management Administration (FEMA). NIMS protocols would be activated in the event of a catastrophic incident, which would necessitate emergency responders from neighboring jurisdictions, or states, to assist. Aside from being a requirement, NIMS compliance ensures the preparedness of Warrenville’s emergency services (Police, Fire, and ESDA) and the safety of Warrenville residents.
