Proper evaluation of blood stain evidence is a critical element in the reconstruction of a crime scene. This comprehensive 40-hour workshop is designed to assist the investigator in the documentation and identification of bloodstain patterns. Investigators must recognize stains and patterns of blood and institute methods to identify, document, and preserve the evidence. Preservation of stains and patterns can only be accomplished through notations, measurements, photography, and sketches prior to collection. Being familiar with blood stain evidence enables the investigator/technician to:

• Develop well preserved scenes for future evaluation
• Evaluate circumstances and statements
• Reconstruct the chain of events involving bloodshed
• Collect pertinent stains for analysis
• Plan strategies, eliminate suspects, or objects
• Prepare cases for trial
