How to fill out basic bloodstain pattern analysis?

1. Obtain the necessary materials: To begin the analysis, gather the required materials such as latex gloves, evidence collection containers, clean paper, rulers, and a camera.
2. Document the scene: Prior to collecting any evidence, it is essential to document the scene thoroughly. Take photographs from multiple angles to capture the overall layout and context of the bloodstain patterns. Make sure to include reference objects in the images for scale.
3. Establish the pattern's directionality: Determine the directionality of bloodstains by identifying the pointed end and the tail. Measure the length and width of each stain and document the pattern's shape (e.g., circular, elliptical, or irregular).
4. Classify the bloodstain patterns: Based on their shape and characteristics, classify the bloodstain patterns into categories such as passive drops, spatter, or transfer stains. Consider factors like velocity, impact angle, and surface texture when making classifications.
5. Analyze the distribution of bloodstains: Assess the overall distribution of bloodstains within the scene. Look for patterns that indicate height, movement, or potential sources. Measure the distance between individual bloodstains and document any anomalies or unique patterns.
6. Interpret the bloodstain patterns: Use your knowledge of physics and biology to interpret the bloodstain patterns. Consider factors such as the droplet's origin, the impact angle, and the force required to create the observed pattern. This analysis can help reconstruct events and identify potential scenarios.
