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.
