A crime scene is a location where an illegal act has occurred, often involving a victim or suspect. It is crucial for law enforcement to secure the area to preserve evidence, which can include fingerprints, weapons, or clothing. Investigators carefully document the scene through photographs and sketches to analyze the details later. The investigation process at a crime scene involves collecting physical evidence and interviewing witnesses. Forensic experts may also examine the scene for DNA or other trace materials. Proper handling of evidence is essential to ensure it can be used in a court of law during a trial.
