BLOODSTAIN PATTERNS AND THE USE OF DIGITAL AID IN INTERPRETATION: A REVIEW

The study or examination of bloodstain patterns at the crime scene can be helpful in sequencing the events occurred and reconstructing the crime scene. The blood pattern analysis can determine the primary idea of type of crime that has occurred. Several people die as the reason of Homicide and blood patterns is found at such crime scenes. The various fields like physics, mathematics, and fluid mechanics is involved from documenting to interpreting the blood patterns. The bloodstain evidence at the crime scenes also contribute in testing DNA. The aim of this paper is to review the detailed information on types of crime scenes and the blood patterns that can be interpreted at the different crime scenes based on the previous studies and research. The technologies and developments to examine the crime scene with blood patterns is also studied with the help of research papers. The digital aid in particular is helpful in interpreting the bloodstain patterns. Keywords— Crime scene, Bloodstains, Bloodstain pattern analysis, Blood spatter, Forensic Science
