Crime Scene: Biological Evidence

Part 1: Find, Identify, and Preserve

One of the aspects of forensic science that can help solve crimes for years is biological evidence. Consider a crime scene that your team might have been called to this week. The supervisor of your crime scene unit wants to see what you have learned. For Part 1, identify at least 5 different types of biological evidence and explain how to collect and preserve it.
