What is Crime Scene Investigation?

Crime Scene Investigation (CSI) is the meticulous process of examining a crime scene to uncover what happened. Investigators document the scene, collect physical evidence, and use forensic tools to piece together the facts.

Key Types of Evidence:

• • Fingerprints & DNA: Identify suspects and confirm presence at a scene.
• • Photography & Notes: Preserve visual and written records for court.
• • Trace Evidence: Includes fibers, hairs, or fluids that offer additional clues.
• • Digital Evidence: Phones, messages, and GPS data are increasingly used in modern investigations.

Popular CSI Careers:

• • Forensic Photographer
• • Fingerprint Analyst
• • DNA Expert

Each role plays a unique part in solving crimes and supporting the justice system.
