Abstract
A diversified range of physical and chemical methods is available for the development of latent fingerprints. But fingerprints exposed to extreme conditions like fire or arson are generally perceived to have been damaged. Electromagnetic radiations, soot deposition and high temperatures are the forces generated in fire which may affect the fingerprints at the scene. Thus the potential value of highly crucial evidence like fingerprints remains unutilized. The study was conducted to determine if fingerprints could be developed after being subjected to arson/fire scene simulation. Fingerprints on non porous surfaces were subjected to high temperature, soot deposition and subsequently treated with water. A novel fluorescent and a pre existing small particle reagent was investigated for the same. Zinc carbonate based fluorescent small particle reagent was capable of developing latent fingerprints exposed to a maximum temperature of 800
°C.
