Following this deconstruction of the problem, it is possible to conduct a gap analysis of the current procedures and identify areas where additional effort is required in the future. In this paper, a seven-step reasoning method for evaluating damage in order to determine the area of origin is proposed, as well as a new definition for the term "fire pattern" (fire pattern). The examination of fires is one of the most demanding forensic sciences since the fire itself continuously alters or destroys evidence, making it difficult to reconstruct the events that occurred. Fire is a highly three-dimensional, time-variant process with time-variant boundary conditions that occurs in a highly three-dimensional space. It is also challenging for forensic scientists studying fires to determine where the fire originated because the observations of damage after a fire may frequently be independent of the direction travelled by the fire, making it difficult to determine where the fire originated.
