huhU.. sALAm untuk PAra pemBAca..uhuH.. tajuk nih merupakan tesis aku.. so aku nak kongsi ngan para pembaca tentang forensik.. tapi berkaitan corak darah erkkk. sains forensik ni besar... ader toksikologi,serology termasuk darah, seemen,, aderpasal hair, fingerprint and memacam lagi.. my Supervisor is mama EdaH

ABSTRACT

Crime scenes that involve bloodshed often contain a wealth of information in the form of bloodstains. It is because the blood is one of the most significant and frequently encountered types of physical evidence associated with the forensic investigation of death and violent crime scene. Blood spatter pattern analysis (BPA) is the examination of the shapes, location, and distribution in order to provide an interpretation of physical events. The aim of this study is to follow the standard procedures in collection and packaging of blood evidence at a simulated crime scene. Evidential blood left at the scene were able to identify the biology of blood and its origin by using presumptive tests such as luminol, phenolphthalein and Katayama test. It also can determine the identity of victim or criminal using serology testing such as ABO, Rh test and DNA. This study also aim to analyze blood spatter pattern by reconstruction through experiments such as dropping blood, passive, transfer and spatter stain. Blood spatter was influenced by type of surface, height and angle of trajectory. BPA at the simulated crime scene can be used to establish when, where and how the assault took place, what kind of the weapon and how close the assailant was to the victim.
