Bloodstain Interpretation

Cost: $600.00

POST Credit Hours: 40

Instruction: IPTM

The St Paul Police Professional Development Institute (PDI) presents a 5-day course in Bloodstain Interpretation.

Bloodstain pattern interpretation can play an important role in determining what happened at a crime scene. This intensive “hands-on” course will arm you with the skills to identify, analyze, document, and collect bloodstained evidence.

Through a variety of practical exercises, we will teach you how a bloodstain pattern is created and the physical mechanics involved. You will learn the various types of patterns that may be encountered and methods for determining their directionality and angles of impact on different surface textures. Together with an analysis of the evidence, you will see how to separate the patterns into events and determine the probable sequence in which they occurred. We will also discuss the proper methods of photographing and documenting bloodstain patterns along with the proper handling and packaging of bloodstained evidence.

Topics include:
• Origin of bloodstain patterns
• Identification of stains and patterns
• Collection and preservation of bloodstain evidence
• Photography and documentation techniques
• Interpretation of bloodstain patterns
• Pattern analysis in scene reconstruction
• Case preparation and presentation

Notes: You should bring appropriate clothing for the outdoor shooting range activity and physical contact with veterinarian provided animal blood, related to the bloodstain pattern exercise. You are also encouraged to bring your camera for documentation of evidence experiments.
