Crime Scene Evidence

Paint

Physical and chemical analysis of paint can indicate it's class or what type of paint it is (auto, house, nail polish, etc.) Individual characteristics, such as the color, number of layers, chemical composition, or features of paint chips, can be analyzed and used for matching evidence to a suspect.

Glass

Particles found at various crime scenes (breaking and entering, hit and run, vandalism, or murder) will be analyzed to determine its properties, such as color, tint, thickness, density, chemical composition, and refractive index (RI).

Explosives

Examination can determine the chemical composition to identify the type of explosive used and its origin. Traces of explosives found on a suspect may be matched to explosives from the scene. Materials used to make an explosive device will be compared to evidence found in the suspect's possession.
