The word Serology means Serum and its analysis is fits in Forensic Serology. Forensic Serology the field that comprises the collection and detection of blood, saliva, semen, vaginal secretion, and other bodily fluids. Forensic Serology includes one more term as DNA analysis or DNA profiling. The DNA is analysed Blood or semen in his branch because if the blood and semen are present in a live form or the instant evidence so that it has DNA live and it is examined in a forensic laboratory by this DNA sample, we can identify individual Characteristics like – gender, the link between suspect and evidence, etc.
These pictures depicts splatter of blood on different areas like on paper, floor, walls, bus which can be seen in violent crimes like suicide or homicide. Passive blood droplets can also be seen on floor which is due to slow dripping of blood under gravity.
This bloodstains can see when blood drop falls on the surface with an angle of impact of different angles like 90⁰, 60⁰ with height of nearly 1 foot to 4 – 5 feet. Studying of different blood patterns are known as bloodstain analysis. This helps to determine the height from which the blood has dropped and on which angle which also helps in determine about the crime scene and helps in crime scene reconstruction.
All this pictures shows different types of blood splatter on papers, floor, etc. Each blood splatter depict different pattern of crime may it be suicidal or homicidal. Also in some pictures pools of blood can also be seen. Properly collected and preserved blood evidence can establish a strong link between an individual and a criminal act. Also, it helps in crime scene reconstruction.
These pictures depicts blood under microscope. If we place a drop of blood on a clear slide and place a cover slip on it and place it under microscope, we can see red blood cells (RBCs), white blood cells (WBCs) present in it.
Here blood group test is performed on the collected blood evidence from the crime scene. By performing antibody and antigen test we can determine the group of the collected blood. This helps to link the blood evidence to the victim or the individual present in the crime scene.
Hair evidences can seen in crimes like rape cases, hit and run cases, homicides, etc. If roots of hair can be found attached on the hair then we can extract mtDNA from it which can give maternal genes.
With development in forensic science in the past year, there is need for making a collection of data where all the information can be preserved. National Museum of Forensic Science is created while keeping this in mind. It contains information from many cases from different fields of forensic science including forensic chemistry, forensic toxicology, questioned document, forensic ballistics, and many more. This data will help forensic enthusiasts, school students to clear concepts of different sciences and will guide types of evidences found in forensic science.
