Bloodstain Interpretations on Textile Surfaces Are Complex
Bloodstain patterns can help determine what happened in a violent incident. NIJ-supported researchers from North Carolina State University found that interpreting blood spatter patterns on textiles – such as clothing or carpeting – is much more complex than interpreting patterns on hard surfaces. Their research showed that blood spatter patterns varied based on whether the fabric was stiff or soft, loose or taut, or touching another piece of fabric. Even the type of yarn used in a fabric resulted in dramatic differences.
