What burn pattern on walls could indicate multiple points of origin?

The V-shaped burn pattern is indicative of fire behavior and can suggest the presence of multiple points of origin. This pattern occurs when a fire spreads upward and outward from a source, creating a V shape that points towards the origin of the flames. When multiple fire origins are present, the resulting burn patterns can overlap, resulting in multiple V shapes, which can be interpreted as distinct points from which the fire started.

This pattern is critical in fire investigations, as it helps responders and investigators to determine the fire's origin and the potential causes behind it. Understanding burn patterns, such as the V-shaped pattern, is essential for firefighters and fire marshals to analyze fire scenes effectively and take the necessary steps to prevent future incidents.
