What does a "V" shaped burn pattern indicate?

A "V" shaped burn pattern is a significant indicator in arson investigations as it typically represents the area of origin of the fire. This shape occurs because flames tend to rise and spread outward from a central point, and as they do so, they tend to concentrate their heat more intensely in the area closest to the source. This concentrated heat results in more severe charring and burn patterns, creating a "V" shape pointing towards the point of greatest heat exposure.

In the context of understanding fire dynamics, the "V" shape forms as flames travel upwards and outwards, hence tapering off as they move away from the origin. This information is crucial for investigators, as pinpointing where a fire was started can help determine the cause – whether it was accidental or intentional. Recognizing this pattern can lead investigators to the source of ignition, which is essential for understanding the circumstances surrounding a particular fire incident.
