Forensic investigators are professionals who use scientific methods to analyze evidence from crime scenes. They collect and examine physical materials, such as fingerprints, blood samples, and digital data, to help solve crimes. Their work is crucial in providing law enforcement with the information needed to identify suspects and understand the circumstances surrounding a crime. These investigators often collaborate with other experts, including crime scene technicians, forensic scientists, and law enforcement officers. They may also testify in court to explain their findings, ensuring that the evidence is presented clearly and accurately to support legal proceedings.
