A forensic expert is a professional who applies scientific principles and techniques to investigate crimes and analyze evidence. They often specialize in areas such as forensic biology, forensic chemistry, or forensic anthropology, helping law enforcement agencies understand the details of a case. Their work can involve examining physical evidence, such as fingerprints, blood samples, or digital data, to provide insights that can be crucial in solving crimes. These experts often testify in court as witnesses, explaining their findings to judges and juries. Their role is vital in the criminal justice system, as they help ensure that evidence is accurately interpreted and that justice is served based on factual information.
