Development of forensic blood substitute: Focusing on luminol reaction functionality.

Bloodstain pattern analysis (BPA) is essential for reconstructing crime scenes using the shape and distribution of bloodstains. Luminol, which emits blue light in a chemiluminescent reaction with hemoglobin, is commonly used to detect latent blood. Artificial blood substitutes, designed for luminol reactivity or bloodstain pattern reproduction, are widely used in forensic experiments.

A study on the estimation of area of origin of swing cast-off pattern.

In bloodstain pattern analysis (BPA), a field of forensic science, there has been active discussion on the estimation of the area of origin of impact spatter. However, there is no established methodology to quantitatively analyze the area of origin of a swing cast-off pattern. To quantitatively analyze the methodology of previous research on estimation of area of origin, a device for generating uniform swing cast-off patterns was produced.
