Fire & Explosion Investigations

Response

Division of Fire Safety Fire investigators, who are Missouri POST licensed law enforcement officers, are on call 24 hours a day, seven days a week. They are stationed throughout the state and respond to requests for assistance from local fire departments and law enforcement agencies for fire and explosion investigations. To contact an investigator, contact the Missouri Information Analysis Center (MIAC) at 573-526-0134. The Jefferson City Central Office can be contacted directly Monday through Friday, except holidays, between 8 a.m. and 5 p.m. at (573) 751-0501.

Basic requirements to request a division investigator are:

• Official request from a fire or law enforcement agency.
• As much information as possible about the incident should be transmitted to the investigator. If at all possible, the investigator needs to speak directly with someone at the incident scene or who has been at the scene.

The highest priority response is assigned to fires involving fatalities or injuries, explosions, evidence of arson or explosive devices, and major disasters. The Division of Fire Safety acts as an assisting agency to local authorities and does not respond to requests for investigations from insurance company representatives or directly from the public. The division does not generally investigate natural cover fires, hay bale fires, or undiscovered losses (in which a fire was not discovered until it had burned itself out).

Scene Security

Scene security is extremely important during any fire investigation. It is important for local authorities to remember that if a DFS investigator will be requested, the scene should be kept as free of contamination as possible and overhaul operations should be limited to affected areas.

To properly secure a fire scene, entry must be limited to only those authorized personnel with duties in the structure. Personnel should be posted at all points of entry into the structure to keep unauthorized individuals out. It is particularly important that the scenes of fatal fires be secured until the investigation has been completed. Many times, the area surrounding the victim may contain valuable evidence. This entire area should be preserved until the investigator determines all evidence has been collected.

If an investigator will be assisting, evidence should be left where it is found unless there is a possibility of further destruction by fire. If local personnel seize evidence, it must be secured in unused air-tight metal or glass containers.

Explosions/Bombings

Personnel should take extra care at the scene of an explosion. Structural stability is always questionable following an explosion. If there is a possibility that the incident was the result of an explosive device, there is a chance of undetonated explosives or a secondary device being present. The closest bomb squad or Highway Patrol Explosives Unit should be contacted for any "render safe" procedures. Division of Fire Safety investigators are not trained or equipped to disarm potential bombs.

Scene security can be extremely difficult in these incidents due to wide-spread destruction and scattering of debris over a large area. All precautions should be taken to protect any possible evidence and the incident scene.

Follow-up Investigations

An important part of any fire investigation is the follow-up investigation if it has been determined that a crime was committed. As licensed law enforcement officers, Division of Fire Safety investigators are trained in criminal investigation techniques and will assist local authorities in any follow-up investigation or incidents they have become involved with. Investigators are trained not only in fire investigation techniques but also in evidence collection, interviewing, fraud investigation, and other aspects of criminal investigation. In addition to arrest authority in investigations, the Division of Fire Safety also has the power to issue subpoenas to assist in obtaining some of the information required in an investigation.
