Forensic FAQs

The entire gamut of scientific disciplines comes into play in currently popular television shows like Forensic Files (A&E), Crime Scene Investigator (CBS) and The New Detectives: Case Studies in Forensic Science (Discovery Channel). If you are unfamiliar with these shows, think of famous book detectives like Sherlock Holmes or Miss Jane Marple who use science to catch “bad guys” and keep “good guys” out of jail. Forensic scientists work in sophisticated crime laboratories each day on real investigations to examine, identify, evaluate, and objectively describe evidence from actual crimes. The work of forensic scientists produces clues to track down criminals, free the innocent, and convict the guilty. People who join the Illinois State Police as a forensic scientist trainee become part of this exciting and rewarding profession.
