How should the investigation process of a vehicle be divided?

Dividing the investigation process of a vehicle into three general compartments is effective because it allows for a systematic approach to examining different areas of the vehicle for evidence of fire origin and cause. The three compartments typically consist of the engine compartment, the passenger compartment, and the trunk or cargo area.

Each of these compartments can present unique challenges and characteristics related to fire behavior, fuel sources, and potential ignition sources. The engine compartment may contain flammable fluids like gasoline or oil, which could contribute to fire spread. The passenger compartment often contains personal items that might ignite and provide clues about the occupant's activities. The trunk or cargo area may hold additional sources of fuel or materials that could influence the investigation.

By dividing the vehicle into these three compartments, investigators can focus their efforts on examining each area thoroughly, assessing the impact of the fire on the vehicle's structure, and gathering pertinent evidence needed to determine the fire's cause. This methodical division enhances the organization of the investigation and ensures that potential evidence is not overlooked.
