The Fire Investigation Unit is responsible for determining the cause and origin of all unknown, suspicious fires and/or explosions occurring within the City of Rock Island. The Fire Investigation Unit consists of the Fire Marshal and three Fire Investigators.

All Fire Investigators have successfully completed the Illinois State Fire Marshal’s Certification through the Illinois Fire Service Institute located in Champaign, IL.

Understanding fire cause is vital to the safety of the community and investigations will decrease the number of incendiary and accidental fires. The Office of the Fire Marshal conducts criminal investigations and prosecutes individuals responsible for incendiary fires or illegal fire-related activities.
