About This Course
Crime Scene Investigation (CSI) is a critical process in the justice system, requiring careful observation, methodical procedures, and unwavering attention to detail. This course provides a foundational overview for those interested in forensic science, law enforcement, or criminal justice. You'll learn the systematic approach investigators take when arriving at a scene, ensuring its integrity, and meticulously documenting everything observed.
We cover techniques for identifying, collecting, and preserving various types of physical evidence, from fingerprints and trace evidence to biological samples. You'll gain awareness of common forensic analysis methods and understand the vital importance of maintaining the chain of custody for legal admissibility. The course culminates in a mock crime scene simulation, allowing you to apply learned concepts in a practical context.
