The field of forensic science includes a number of disciplines, such as anthropology, odontology and toxicology. These experts find, collect and preserve evidence in criminal cases.
Anthropologists have expertise in both archeology and the human skeleton. Those who specialize in digital and electronic forensics find clues in computer and phone files, and forensic engineers tend to use physics and chemistry to aid investigators in the legal system. Odontologists, or forensic dentists, assist investigators by studying bite marks and skeletal dental remains, while forensic pathologists determine the causes and manners of death. Those who specialize in questioned documents not only study handwriting and indented writings, but also classify typewriters and computers. Toxicologists look at chemicals and drugs in the body, and forensic psychologist and psychiatrists determine if suspects are competent to stand trial.
