Patrol Division

The core mission of the Fairview Heights Police Department is carried out by our Patrol Division officers. Every other division and unit in the Police Department, including the Chief of Police and administrators, are there to support what Patrol does day in and day out.

Patrol officers are counted on by this community to:

· Respond to emergency calls for help;

· Act as keepers of the peace;

· Investigate and report on crimes and incidents;

· Make arrests as needed;

· Enforce traffic laws and investigate traffic accidents;

· Patrol neighborhoods and businesses to prevent and detect crime.

The Patrol Division is made up of 28 officers, divided into 4 teams. Each team is led by a patrol sergeant. The teams work 12 hour shifts. The team is assigned to work together on the same shift for a full year. There is no rotation and no switching of shifts, normally.

On the day shifts, the team consists of the sergeant and seven officers. On the night shifts, the teams are a sergeant and five officers. The Patrol Division also has two canine officers.

Criminal Investigations unit

The Fairview Heights Police Department’s Criminal Investigations Division supports the other divisions of the department by conducting follow-up investigations of reported criminal activity and if warranted presenting cases to the St. Clair County States Attorney’s office for prosecution. Detectives review preliminary investigations conducted by patrol officers and then interview victims, witnesses, and suspects. Personnel assigned to the unit posses special knowledge and skills in interviewing, crime scene processing, interpersonal communication, and constitutional issues such as search and seizure. Detectives within the division are members of the St. Louis Metropolitian Major Case Squad and the Child Death Investigations Squad.

The division is comprised of a Division Commander, Detective Sergeant and seven sworn officers. Four of the officers serve as detectives investigating general criminal activity that has occurred within the city of Fairview Heights. One officer serves as the juvenile detective primarily investigating crimes and civil matters involving persons under the age of seventeen.  Two officers are on special assignment with outside law enforcement agencies. One officer is assigned to the Metropolitian Enforcement Group of Southwestern Illinois, which investigates street level drug crimes that occur within a multi-county area. The other officer is assigned to the Drug Enforcement Administration Taskforce.  The Taskforce investigates drug offenses that are of such a nature that they fall under federal jurisdiction.



Records Department, staffed by two civilian employees, is responsible for the overall processing, maintenance and digitizing of department records and reports. This includes all reports pertaining to crimes, accidents, services, arrest records, traffic citations and warning tickets. The Records Department is responsible for the preparation of the monthly Illinois Uniform Crime Report. They provide assistance to citizens and law enforcement agencies as necessary. The department functions under the direct supervision of the Supervisor of Support Services.

Honor Guard

In April of 2008, the Police Department formed its first Honor Guard unit. The Honor Guard unit was established to serve as official ambassadors of the Police Department for fallen police officer/firefighter funerals, ceremonial presentations and indirectly for recruitment purposes.

Former Chief of Police Edward Delmore called upon an old friend, Darrin DeCoster, of the Fairfax County Va. Police Department to help drill the unit during its formation. DeCoster was a member of the Army Old Guard and also served as a sentinel at the Tomb of the Unknown Soldier. DeCoster instructed the unit on drill moves, hand movement, flag etiquette, rifle and flag presentations, posture and grooming.

Before the first week of instruction was over, Former Chief Delmore arranged for the Honor Guard to present the colors during the National Anthem for the 2008 Cardinal’s baseball opening game. Since that time, the Honor Guard has been requested to present the colors at several events including SWIC Police Academy graduations, the FHPD senior and youth academies, the St. Louis Blues Hockey Team Heroes night, Grace Church Memorial Day celebration, the Guns & Hoses Police vs. Firemen boxing match, the Southern Illinois Police Chief Association & Southern Illinois Law Enforcement Commission annual training seminar. This year they will be participating in the Law Enforcement Officers Memorial in Springfield, Illinois and St. Clair County and served at the funeral of Lt. Jonas, Centreville Police Officer who was shot and killed on duty.

In September of 2008, the unit attended a week long Honor Guard boot camp hosted by the Goshen, Indiana, Police Honor Guard. The team was actually split into two separate units during the camp. The top team of the academy had the honor of being the Honor Guard for a full mock fireman’s funeral as a graduation exercise on the last day of camp. The teams had to perform a predetermined set of drills inside a designated area. The Fairview Heights Police Honor Guard took first and second place in the drills.

The Honor Guard currently consists of 10 members.
