Forensic investigation is the application of scientific methods and techniques to solve crimes. It involves collecting, preserving, and analyzing physical evidence from crime scenes, such as fingerprints, DNA, and other materials. Forensic investigators work closely with law enforcement to help identify suspects and establish connections between evidence and criminal activities. The process often includes various disciplines, such as forensic biology, forensic chemistry, and forensic anthropology. Each of these fields contributes specialized knowledge to the investigation. Forensic investigators may also testify in court as expert witnesses, explaining their findings and the significance of the evidence to judges and juries.
