The usage of depth of char and relating this depth to period of burning has fluctuated concerning its usefulness in fire investigations For the reason that mid-1950’s. Kirk’s (1969) text was the initial reference that indicated investigators could use this info For additional than just direction of injury when he spelled out “investigators make measurements with the thought of identifying the period of time the fire burned at this time”.
