The objective of the present study was to determine the size of the bloodspots produced by the blood drops of different volume (5, 20, 40, and 80 mcl) falling down from different heights to enable the evaluation of the height of a suspended bloodstained object. The bloodspots of the blood drops of different volume (5, 20, 40, and 80 mcl) falling down from different heights were obtained under the experimental conditions. It was shown that the size of the bloodspots increases with the increasing height of fall: the greater the height the larger is the diameter of the bloodspots. Given that the drop volume is known, the size of the bloodspots can be used to determine the height of the suspended bloodstained object. In the practical work of the forensic medical expert, the blood drop volume is as a rule unknown, therefore the height of their fall can be roughly determined based on the morphological features of the bloodspots.
