What are the different types of forensic?
Forensic science is essential in gathering evidence of suspects and to help to determine exactly what has happened to the victims. Scientists working in this area use scientific evidence with legal interpretation and can work as consultants for agencies, including law firms, law enforcement and criminologists. It is a complex and demanding field that is divided into many different types of forensic or specialties, including computer forensic, forensic toxicology and forensic anthropology.
Computer Forensics is an area of forensic areas in which technicians collect and analyze data from a computer or other forms of digital media. When someone has been charged with a crime involving the download of obscene materials from the Internet or sending harmful and annoying e -mails, the Federal Office of Investigation (FBI) can check their computer records of e -maly, downloading and the history of the Internet. Sometimes the computer is confiscated and listed as evidence on the -sale negotiations on the matter.
Another type of forensic is forensic toxicology, which includes the study of chemicals, such as medicines and alcohol to determine whether someone has been abusing drugs or whether a toxic substance played a role in the death of a person. To see if the person has been poisoned, the person performing autopsy analyzes the blood of the victim, hair or organ tissue to check toxic chemicals. During the toxicological examination, the medical investigator also checks the stomach content to find out what the person eats last. The content of the person's stomach can help investigators gain the timeline of events leading to the extinction of the victim based on how the food is spent and also to give the idea of the last victim's activities.
Sometimes the body has spread to the extent that the authorities leave only the skeleton to find out who the person is and what happened. This type of forensics is known as forensic anthropology and includes scientists investigating fragments of bones nand traces of circumstances surrounding the death of an individual. If the skeleton has any teeth, the technicians will receive X -rays of teeth and try to connect them with dental records of missing individuals. Other methods used in forensic anthropology are the condition of the clothing that the person was wearing, bone density and the number of bones available for examinations. The longer the body was in a particular place, the less bones the remaining analysis is due to animals and environmental factors that can move bones.
Forensic scientists must meet specific requirements for education and have extensive training in their specialties. There may also be certain state or jurisdiction licenses or exams that an expert would have to pass to work for the agency. In addition, forensic scientists who regularly help lawyers at the stand in experimental certification specifically for this purpose.
