This course will teach an understanding of the fundamental theories of physical evidence, practical application; and the legal consideration involved in its collection, preservation and presentation in court.

The solution of crime focuses increasingly upon the discovery of various forms of physical evidence at crime scenes and subsequent scientific laboratory analysis. There is a need to improve knowledge of law enforcement personnel in regard to physical evidence. These personnel should be skilled in the recognition of physical evidence and be capable of preserving it for laboratory processing.
