The course will provide a basic and fundamental knowledge in the field of bloodstain pattern interpretation. It will illustrate the scientific principles and practical application of bloodstain pattern analysis to actual casework. Emphasis is placed on proper identification, documentation, interpretation, and presentation of bloodstain patterns. The course will include analyzing multiple bloodstain events and cognitive bias.
Course Objectives: As a result of instructional activities, students will be able to achieve the following course objectives:
- Describe the development, history, and advancement of bloodstain pattern analysis.
- Describe the inherent limitations of bloodstain pattern interpretation.
- Recognize, document, collect, preserve, and examine bloodstain pattern evidence.
- Recognize and distinguish between spatter stains and non-spatter stains and sequencing events.
- Understand bloodstains on clothing, absorbent/non-absorbent substrates.
- Recognize and interpret the mechanism by which bloodstains were created.
- Recognize the variety of wounds and various weapons used to create wounds.
- Explain the mathematical relationship which apply to bloodstain patterns in determining Area of Convergence and Area of Origin.
- Prepare scientifically-based reports, peer-review and courtroom testimony.
- Understand cognitive bias, subjective v. objective
