Principles of Bloodstain Pattern Analysis introduces students to the science of interpreting bloodstains at crime scenes to reconstruct events and establish investigative leads. Through a combination of lectures and hands-on field exercises, participants will explore the principles behind bloodstain formation, including impact patterns, spatter analysis, and the role of gravity, surface texture, and force. This session will teach students how to methodically document, analyze, and interpret bloodstain patterns, equipping them with the essential skills needed for forensic investigations involving violent crimes and providing insights into how blood evidence can support or refute theories of criminal activity.
