The Team Concept: Duties and Responsibilities
Implementing the "team concept" as illustrated in this chart
has been shown to be the most complete and efficient method for a systematic
and thorough fire investigation. Putting the team concept into practice
requires the local fire investigator to build an effective investigatory
team by taking a fresh look at the resources already in place in the community,
county, state, and nation and seeking out new resources. When creating
a fire investigation plan for your community, fully explore all available
resources and personnel, including the municipal police department, sheriff's
department, state police or state criminal investigation bureau, State Fire
Marshal's Office, and ATF Field Office. Making these contacts not only
adds individuals to the team, but also brings all of their agency's resources
to bear, such as an affiliated forensic accountant, a public records database,
a well-equipped crime scene technician, or a list of approved forensic laboratories.
After bringing all the pertinent agencies to the table and securing commitment,
define each agency and individual's role in the fire investigation and how
each will execute their duties.
The investigation of a fire can involve a team as small as two or as
large as fifty or more, depending on the incident and on available resources.
The exact composition of the team will be defined by the resources available.
Therefore, specific individual roles will be determined on a case-by-case
basis. Although the specific task assignments will differ, the duties that
must be discharged at the fire scene remain the same.
Even if your team consists of only a fire investigator and a police officer,
you can follow the model outlined here and efficiently assign duties and
properly carry out all investigative tasks. For larger teams, the coordination
of duties can be facilitated through a team leader.
Team Leadership is responsible for the overall conduct of the
investigation, including the safety of all personnel.
Team Leadership Duties
1. Select and assemble personnel/equipment and coordinate with other
jurisdictions.
2. Conduct scene overview.
3. Determine and establish scene integrity, security, and safety.

and Cause and handling Forensics.

7. Assign Immediate Area Search and Investigative personnel.
8. Assign General Area Search and Investigative personnel.
9. Manage, evaluate, and finalize search and investigative actions.
10. Conduct final scene evaluation conferences.
Origin and Cause Investigation concentrates on determining the
area or areas where the fire started and how the fire was ignited. Elimination
of accidental causes and pursuit of evidence of incendiary cause fall within
this duty.

2. Accompany Team Leadership on walkthrough in order to provide a technical
evaluation and assessment of fire scene.

ruling out all accidental causes.
8. Reconstruct the sequence of events and physical evidence.
9. Provide technical briefings.

noticed by witnesses.
7. Question the witnesses and record facts pertaining to the general

investigation, feeding information from witnesses.
10. Alert team leadership to information given by witnesses, for example,
whether a window was open or closed.
The General Area Investigation interviews persons who may not
have direct knowledge of the fire scene, but might have details about the
people, the property, or the events surrounding the fire. This would include
responsibilities like conducting the neighborhood canvass.
General Area Investigation Duties
1. Select and assemble investigative equipment.
2. Review maps and evaluate ingress and egress and select a systematic
pattern for canvassing the area.
3. Search area of ingress and egress for associative evidence, such

for future use.
10. Check sources of evidence recovered at the crime scene.

to the fire, such as a discarded flammable liquid bottle. Mark these locations
for the team members responsible for Photography and Schematics.
12. Alert team leadership to any potential areas of evidence, such as
where a car was parked at the time of the incident, and any information
gained from the canvass.
Photography completely documents the scene and evidence collected.
Photography Duties
1. Select and assemble equipment.

The Follow-Up Investigation should be conducted after the scene
has been processed. It can include looking into financial, insurance, personal,
and civic records to support the cause determination . If a crime has been
committed, the follow-up investigation will concentrate on identifying evidence
of participation and establishing a case.
Follow-Up Investigation
1. Coordinate with on-scene team members for case briefing.
2. Review all case materials, including photographs, witness statements,
lab reports and the like.
3. Based on cause determination made at scene, create appropriate follow-up
investigation plan.

additional tests if necessary.
6. Coordinate with necessary information-yielding organizations like
insurance companies, police departments, and government agencies.
7. If accidental fire is determined, report product or system faults
to appropriate regulatory and consumer-protection agencies.
8. If incendiary fire is determined, spearhead investigation into motive,
including interpersonal, financial, and insurance, and evidence of participation.
9. Maintain case records through trial phase, if necessary, and help
expert witnesses prepare for trial.
Although the team concept is the best approach to fire scene investigation,
there is a tendency to overlook its implementation because of a perceived
lack of available resources. This is unfortunate. No matter how many assets
are available, the outlined nine investigative duty areas need to be considered,
assigned, carried out at the scene, and documented. Consolidating the tasks
or taking on multiple roles may be necessary given your team structure,
but none of these duty areas should be neglected. In addition, these duties
and tasks should be assigned ahead of time so that the system can function
smoothly when a fire needs to be investigated. This planning and coordination
will save time and improve quality at the fire scene. Although this task
may seem difficult at the beginning, the responsibilities and coordination
outlined here will flow naturally once you have started the process and
think proactively about fire investigation.
