Trace evidence consists of small items of material largely made up of human and animal hair, cloth fibers (natural and synthetic), items such as geological soil, small glass particles, pollen, wood splinters, gunshot residue, and small smears or flecks of paint. These items are found throughout many crime scenes and are often overlooked or lost.

• Explain to your CSI partner in training the methods of finding trace evidence, cautions on not losing or destroying it, and collection methods.
• Relate to your partner the components of human hair that are considered class characteristics.
• Further, explain how the Locard Principle plays a major part in the transfer of trace evidence and the importance of identifying and collecting it for the investigation.
