Job Description, Duties & Responsibilities of a Crime Scene Investigator
Forensic science technicians investigate crimes by collecting and analyzing physical evidence. Often, they specialize in areas such as DNA analysis, firearm examination, or performing tests on weapons or substances such as fiber, glass, hair, tissue, and bodily fluids to determine significance to the investigations.
When criminal cases come to trial, forensic science technicians often give testimony as expert witnesses on laboratory findings by identifying and classifying substances, materials, and other evidence collected at the scene of a crime.
A bachelor’s degree from a four-year college is required with a major in criminal justice, chemistry, biology, or physics. This usually includes successful completion of eight semester units of general chemistry and three semester units of quantitative analysis. Some crime labs require a master’s degree in forensic science.
