Document Summary
Identification of weapons used: properties of blood, 4 to 5 litres of blood in the human body, apprx. Blood behaves according to the laws of physics: 2. Bloodstain patterns are predictable and reproducible (science of ballistics: 3. The appearance of a bloodstain is surface dependent ie. bloodstain on concrete will look diff on carpet: will affect size, shape of the stains, smooth and flat surfaces disrupt less of the blood stain, 4. The droplets form spheres due to surface tension and travel according to the laws of motion: categories of (cid:271)loodstain patterns (cid:862)gra(cid:448)ity indu(cid:272)ed(cid:863) (cid:894)passi(cid:448)e(cid:895, when blood falls as a result of the force of gravity acting alone.
