Criminalistics is one of many divisions in the field of forensic science. Forensic science includes forensic pathology, odontology, entomology, accounting, engineering, criminology, and other disciplines. (CACNews.org)

Examinations of an object or situation requiring expertise in a particular specialised field, conducted by a forensic expert (also known as a forensic scientist or forensic science expert).

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.
