Abstract

Blood splatter analysis is a huge part of any forensic analytics, which deals with crime scene investigations, which are in need of reconstruction of the crime scene in order to get a deeper look and insights into the crime scene itself and find out more details towards solving the crime. Many factors influence the blood splatter such as the velocity, the angle of impact and the height of the blood drop. Every such factor provides a key insight into the reconstruction of the crime scene, which provides details as to how the crime actually took place. This paper also looks into an example of why computerized blood splatter analysis triumphs over manual analysis. There have been some recent advances in blood splatter analysis, which are compared The following also provides a brief description toward blood splatter, why the crime scene reconstruction is important, how the blood splatter affects the reconstruction of the crime scene, how it has been used so far in recent technologies and the comparison of these technologies. Finally, concluded by providing the current approaches comparison and the ideas as to how they can be improved further.
