Kennedy and Kennedy (1985) were also the 1st to propose that hurt would be in The form of the triangular, columnar, or conical form once the flame plume had intersected a wall surface in just a compartment.
Based on just how much proof is existing, an investigator can use diverse methods. Two methods include means of elimination, or disregarding the brings about the evidence deems impossible.
