What are the 8 steps? |
1. Become familiar with the entire scene 2. Identify the discrete patterns among the many bloodstained surfaces 3. Categorize these patterns based on an established taxonomy 4. Evaluate aspects of directionality and motion 5. Evaluate angles of impact, points of convergence, and areas of origin 6. Evaluate interrelationships among patterns and evidence 7. Evaluate viable source events to explain the pattern based on all evidence 8. Define a best explanation of events |
