While the fire triangle explains the physics of combustion, arson evidence focuses on how a human actor might manipulate these elements to start or accelerate a fire. The expert witness must translate complex scientific data into terms that a judge or jury can understand without diluting the facts.
Arson Evidence Reading Fire Patterns
The analysis distinguishes between the byproducts of incomplete combustion and the chemical compounds found in commercial fuels. Gas Chromatography-Mass Spectrometry (GC-MS) is then used to identify the specific chemical signature of the accelerant, linking it back to a possible source.
V-patterns on walls, for example, are often cited as indicators of flashover, a phenomenon where all combustible materials ignite simultaneously. Examining arson evidence requires a meticulous approach that bridges the gap between intuitive scene assessment and rigorous scientific analysis.

This process relies on a combination of physical clues, chemical analysis, and behavioral context to build a defensible conclusion. Investigators use specialized tools, including hydrocarbon sniffers and canines, to locate trace amounts of fuel vapors.
