With a certain DNA analysis, then blood and seminal fluids can be traced to an individual and be very accurate in doing so. If not, it can at least be determined from what certain population group it belongs to. The manner in which blood or other body fluids should be obtained is with caution and sterile materials. Tape can lift a stain off and all pieces of evidence should be stored separately. This process is usually taken under by crime scene technicians. In order !.
to preserve any physical evidence, the hands of the corpse are bagged. This prevents anything from contaminating or altering whatever may be under the fingernails or on the skin. Hair samples can tell only if it is human, which race, location of growth on body and how it was removed. Whenever there is a death due to violence, unexpected, sudden or suspicious circumstances, the body is handed over to the coroner. The autopsy, the examining of the body, includes only examining the crime scene, but identifying the body, examining external areas of the body, dissection and internal analysis, as well as examination of the body fluids for drug or alcohol presence. (Campbell) In cases where the body is damaged beyond recognition, the deceased's identity is up to the work of forensic anthropologists. These scientists study the remains of the corpse for clues about the death as well as clues about their life. By looking at the bones, it is possible to tell if the subject was male or female. Noting the ossification, or bone formation, the anthropologist can narrow down the age range. Height and weight, as well as determining which hand was dominant is possible by measuring bones and muscle attachments. Skull dimensions and nose measurements can help figure out the race of the body. Sometimes at crime scenes where a shooting occurs, bullets and casings will be found in the surrounding area. Under examination at the crime lab, the make and model of the weapon can be determined.
