ABSTRACT The fire investigation industry is considered to be lagging behind the rest of the forensic science fields in its assessment of the performance of methodological approaches and conclusions drawn by practitioners within the field. Despite the best efforts of certifying bodies and industry members, there are still many unknowns within the profession. As such, the researchers have collected a large survey of demographics to formulate a picture of our industry with regards to experience, age, employment, training, and opinions regarding methodology within the industry. In addition to these demographics, the researchers collected data regarding area of origin determination both with and without measurable data (depth of char, calcination) to evaluate its effectiveness when applied without an on-site scene examination. This permitted the comparison of the demographics and accuracy in determining the most important hypothesis in fire investigations, the area of origin. It is shown that 73.8% of the participants without measurable data and 77.7% with measurable data accurately determined the area of origin. Thus, the total percentage of participants choosing the correct area increased 3.9% with the inclusion of measurable data as part of the given. Additional selected outcomes from this research are presented within this paper.
