Criminal investigations are systematic processes used by law enforcement to gather evidence and solve crimes. These investigations often begin with a report of a crime, such as theft or assault, and involve collecting information from witnesses, analyzing physical evidence, and reviewing surveillance footage. The goal is to identify suspects and build a case for prosecution. Detectives and forensic experts play key roles in criminal investigations. They use various techniques, including interviews and forensic analysis, to uncover details about the crime. Successful investigations can lead to arrests and help ensure justice for victims, contributing to public safety and community trust in the legal system.
