When locating the point of origin, investigators typically work in which direction?

Investigators typically work backwards from the area of greatest damage when determining the point of origin of a fire. This approach allows them to analyze the impact of the fire and trace back to where it started. By moving in reverse, they can identify patterns of burn progression, detect potential ignition sources, and observe how the fire may have spread through the materials and structures involved. This method is crucial in establishing a thorough understanding of the fire's behavior and ultimately leads to more accurate conclusions regarding its cause. The strategy of exploring backwards helps ensure that no critical evidence is overlooked, as investigators can see the path of least resistance and where the fire likely began before it spread outward.
