Crime investigation is the process of gathering evidence and information to solve a crime. This involves various techniques, such as interviewing witnesses, collecting physical evidence, and analyzing data. Investigators, often part of law enforcement agencies, work to piece together the events surrounding a crime to identify suspects and understand motives. The investigation may include forensic analysis, where experts examine DNA, fingerprints, and other physical traces left at the crime scene. Additionally, detectives may use surveillance footage and digital records to track the movements of individuals involved. The ultimate goal is to ensure justice is served and to prevent future crimes.
