Improvised incendiary devices, such as petrol bombs (Molotov cocktails), are used by criminals, protestors, and terrorists. Forensic scientists face the dual challenges of identifying the liquid fuel to prove criminal intent (arson) and recovering latent fingermarks that may lead to a suspect. This research examines the potential impact of fire debris analysis on fingermark quality, so that the forensic sequential examination of arson debris analysis and fingermarks can be better understood. Our experiment revealed that latent fingermarks deposited on glass, exposed to gasoline, and developed by black magnetic powder were of poorer quality than those exposed to kerosene and diesel fuel. The effect of temperature on gasoline was also investigated. A primary conclusion is that the temperature and the concentration of gasoline inf luenced the quality of developed latent fingermarks.
