What type of evidence are fire patterns classified as?

Fire patterns are classified as artifact evidence because they are the physical remnants left behind after a fire has occurred. These patterns, which include char marks, burn patterns on materials, and the arrangement of debris, provide critical information to investigators about the fire's origin and development, helping to determine how the fire started and spread. Artifact evidence is characterized by its physical nature, which can be directly observed and analyzed, unlike other types of evidence such as testimonial or documentary evidence, which rely on verbal or written accounts. Understanding fire patterns as artifact evidence is essential for fire investigators, as it supports the reconstruction of fire scenes and the analysis of fire behavior.
