ANALYSIS OF VARIATION IN DIAMETER OF BLOOD SPATTER IN VARIOUS SURFACE FROM VARIOUS HEIGHT

Forensic biology is a crucial discipline that applies biological principles to criminal investigations,aiding in the identification of individuals and analysis of biological evidence. This fieldencompasses DNA profiling, forensic anthropology, entomology, and microbiology to solve crimesand identify remains. Advanced techniques, such as next-generation sequencing and microbialforensics, have enhanced the accuracy and reliability of forensic analyses. DNA analysis, inparticular, has revolutionized criminal investigations by enabling precise identification fromminimal biological traces. Bloodstain pattern analysis is a crucial aspect of forensic biology, aidingin crime scene reconstruction by determining the dynamics of bloodshed events. This studyinvestigates the variation in blood spatter diameter on different surfaces when dropped from varyingheights. Factors such as surface texture, absorbency, and height influence the spread and shape ofbloodstains, affecting forensic interpretations. Controlled experiments were conducted using blooddroplets on multiple surfaces, measuring spatter diameters at different heights to identify patterns.The findings provide insights into how surface properties and gravitational forces impact bloodstainmorphology, enhancing forensic accuracy in crime scene investigations.
