Forensic scientists who work crime scenes are trained experts. They compile and examine evidence to help law enforcement agencies determine the perpetrator of a crime. Crime-scene forensic scientists and technicians usually fall into two main categories: those who collect, identify and analyze evidence used in criminal investigations, and those who work as expert witnesses in legal hearings.
