Abstrakt: The purpose of the investigation is to establish the characteristics of a blood drip stains on a surface covered with house dust. In most cases, objects at the crime scene are covered in some degree of dust deposits. Accordingly, in external bleeding wounds, blood drops on dusty surfaces. The experiment established the peculiarities of drip stains on glass covered with dust. Compared with a clean surface, there was a greater number of spines at the edge of the drip stain. There was pronounced widespread and sectoral splashing. This can be explained by the fact that the dust particles are obstacles which, when the droplet spreads across the surface, form an irregular edge and cause splashing.
