MORPHOLOGICAL FEATURES OF CONTACT BLOOD TRACES ARISING WHEN EXPOSED BY HAMMERS OF DIFFERENT DESIGN
The present body of knowledge about the mechanism and morphology of contact traces of blood overlay on material evidence does not meet the modern requirements of the investigation. Based on experimental modeling, in this work, we studied the morphological features and mechanisms of the formation of primary footprints and fingerprints and secondary blood traces caused by the working surfaces of hammers of various designs (metalwork and for beating meat). The obtained results indicate significant differences in the morphological characteristics of blood prints depending on the type of contact (shock, short-term or long-term pressure), the characteristics of the blood carrier and the trace-perceiving surface.
