Forensic examiners, also known as forensic science technicians or crime scene investigators, analyze physical evidence and provide scientific conclusions for the justice system. [...] Forensic examiners are responsible for collecting and preserving the integrity of evidence at crime scenes. They collect hair, fiber and blood samples, lift fingerprints and footprints, make measurements and take photographs. In the laboratory, examiners use equipment and chemical solutions to classify materials and identify unique characteristics, such as the markings that match a bullet to a particular firearm.
