Forensics is a use of science in a field of criminal law when experts gather, investigate and analyse evidence that can be used in court. Forensic investigators are experts in different scientific fields, including chemistry, biology or medicine. Forensic biologists analyse blood, hair or saliva taken from the crime scene. Chemists examine different powders or other types of materials to trace explosives or drugs. Forensic anthropologists investigate the remains to estimate the age of a victim.
The work of forensic experts is crucially important because their research contributes greatly to successful outcomes of a police investigation.
The most common practice of forensic scientists is identifying fingertips at a crime scene. Being unique to an individual, they can confirm a person's identity and at the same time help prove a suspect's innocence. Needless to say, the international fingertips database can help link a series of transnational crimes as the fingertips can be quickly checked if a suspect is crossing the border of another country.
As new biometrical technologies are rapidly developing, forensic scientists can do their job more effectively, avoid mistakes and share evidence quicker.
