What is trace evidence and why is it important?
Trace evidence is extremely important. Trace evidence refers to small evidence, both in size and in quantity. These are minute particles (hairs, fibers, paint chips, glass shards, bullet fragments, chemical residues) that, upon further investigation, can be identified via laboratory analysis. A small speck of auto paint found on the clothing of a pedestrian struck and killed can potentially reveal the make, model, and year of the suspect vehicle. Once the vehicle is located, a search of the vehicle can reveal small fibers and hairs that can be identified via laboratory analysis as belonging to the clothing worn by the victim. Trace evidence can also provide DNA evidence through human hair left at a crime scene or on the body of a rape victim. Just because it is small does not mean that it is not important!
