Crime Scene Investigators are responsible for examining all evidence, including but not limited to vehicles, guns, and documents for latent fingerprints (fingerprints left behind after touching an object) and for comparing known prints to the latent prints in an attempt to identify a suspect. The investigator must keep abreast of the latest techniques for development of latent fingerprints, including chemical formulas, alternate light sources (lasers) and photographic techniques that may enhance the latent fingerprint being developed. A fingerprint is the most positive form of identification and is powerful evidence when presented to a jury during a court trial. The investigator is also trained to examine evidence for blood, hair, soil, and fibers in an attempt to link a suspect to a crime.
