In 1985, Cooke and Ide place ahead a system termed radius of error (Cooke and Ide 1985). Their method inspired investigators to use fire patterns to arrive at an origin, but upon arriving at their hypothetical spot(s) of origin expected the investigator to deliver some evaluate of accuracy in the form of a radius of error. Their illustration fire investigations is as follows, “If your investigator decides he has Found a seat of fire within a radius of error of 1 m, he is definite that the original seat of fire lays inside of a place possessing one particular metres [sic] radius (i.
