Crime Scene Investigation (CSI)

Crime Scene Investigation (CSI) involves the systematic collection, preservation, and analysis of physical evidence from a crime scene. It plays a crucial role in reconstructing events and identifying suspects in criminal cases.

1. Evidence Collection & Preservation
  • CSI teams collect various types of evidence, including fingerprints, blood samples, weapons, and digital devices.
  • Chain of Custody ensures that evidence remains unaltered and admissible in court.
  • Proper storage methods prevent contamination (e.g., biological samples stored in breathable bags).
2. Crime Scene Photography & Sketching
  • Photographs capture the crime scene from multiple angles before evidence is disturbed.
  • Sketches provide accurate measurements and layouts of evidence placement.
  • 3D crime scene reconstruction is used for detailed analysis.
3. Chain of Custody & Documentation
  • Every piece of evidence is labeled, logged, and tracked from collection to courtroom presentation.
  • Digital records maintain timestamps of handling and storage.
  • Any break in the chain of custody can lead to evidence being ruled inadmissible in court.
CSI is the foundation of forensic investigations, ensuring that crucial evidence is properly handled.
