The ability to effectively remove soft tissue from the skeleton without compromising surface morphology or overall bone integrity is essential to a thorough and complete analysis by a forensic anthropologist. There is no agreement among forensic anthropologists regarding the best method for defleshing skeletal remains. Choosing the most appropriate method for defleshing remains and exposing the unique features of the individual must be done with consideration of the forensic context of the remains. The use of undiluted household bleach, as a means of defleshing cadavers is notably controversial in the forensic science literature. Specifically, when bleach is introduced to forensically significant skeletal material, the potential for cortical exfoliation due to the corrosive nature of bleach (sodium hypochlorite) poses a significant threat to the integrity of the outer cortex of the bone. Bleach cleans and whitens bones, which may be appropriate for museum display; in the forensic context it is an adverse product of the process. No single method is a panacea for all situations. Maceration is an invaluable procedure in a forensic context, although not all maceration techniques are applicable to medico-legal cases. Anthropological assessment of the technique’s usability often involves the length and ease of the process, the resulting bone quality and color, and the relative odor (1). Removal of the soft tissue can reveal subtle nuances of trauma that may otherwise be obscured or masked by the presence of flesh (2).
Maceration techniques have been shown to reduce the potential for DNA extraction following maceration (1). As discussed by Mann and Berryman (2), the bleach attacks and oxidizes the protein bonds in the bone, effectively...

The skeleton had a hideous impact to the community and was predicted by local investigators to be reasonably modern. To get better understanding and avoid confusion, a bone sample was sent to a laboratory in the USA for investigation and analysation using series of scientific
“This is my lab and what we do is study bones,” states Kari Bruwelheide in her video entitled “30,000 Skeletons”. Of the three resources that we were provided, “Puzzles of the Chesapeake” by Sally Walker, “Forensic Anthropology” by an unknown author, and “30,000 Skeletons” by Smithsonian Education presented by Kari Bruwelheide, the resource “30,000 Skeletons” is by far the best at explaining the role of an anthropologist. It is unbeatable because it is a video rather than just written words, and Kari Bruwelheide has personal experience in being a forensic anthropologist. A forensic anthropologist is a scientist that studies human remains, or in another word, skeletons, to try to find out information about the past.
In the book “Death's Acre”, By Bill Bass and Jon Jefferson they tell readers how they got to where they are today in their careers and how Dr. Bill Bass became famous for the well known “Body Farm” at the University of Tennessee. In “Deaths Acre” Bass invites people across the world who are reading to go behind the gates of the body farm where he revolutionized forensic anthropology. Bass takes us on a journey on how he went from not knowing if this is what he wanted to do for a living to being in a career that he would never trade. He tells us about the Lindbergh kidnapping and murder, explored the headless corpse of a person whose identity shocked many people included the police, divulges how the telltale traces and case
In conclusion, a trained forensic anthropologist is an important factor to consider when the trauma on the bone occurred, how it occurred and what type it is. With no longer having the flesh on the body, it can make finding cause of death difficult, which is why the forensic anthropologist is
The show portrays that forensic anthropologists are responsible for almost every aspect of the death investigation, which does not correctly depict the role of forensic anthropologists (Wood,2017a). The method of which components of the biological profile, like sex of the remains, is also incorrectly portrayed as Dr. Brennan estimated the sex using a trait that does not accurately indicate sexual dimorphism (Wood, 2017c). Lastly, the complexity of personal identification, which is one of the most important aspects of forensic anthropology casework (Krishan et al, 2016), is not portrayed correctly as Dr. Brennan and her team based the identification of the remains on one trait that has questionable reliability (Charles & Levisetti, 2011). All in all, ‘The feet on the beach’ episode of ‘Bones’ does not accurately portray the forensic anthropology as it is romanticized for entertainment and overly simplified for a lay person to

When a death occurs suddenly, unexpectedly and from unnatural or unknown causes, a forensic scientist has the duty to gather and analyze evidence to determine whether the victim died from a previously undiagnosed disease or infection or from a homicide, suicide or accident (Lurigio, 2009). When considering suicide as the probable cause of death, we are looking at the act of intentionally killing oneself through one’s own effort or with the assistance of another (Sever, 2009). The resolution of the manner of death by a forensic pathologist as suicide is based on a series of factors which eliminate natural causes of death, homicide and accident (Geberth, 2013, p.55). The cause of death is also determined by the medical examiner in conjunction with the crime scene investigator; however, it can only be determined after a thorough investigation is concluded. Therefore, in the complicated process of doing a death investigation there are several mistakes that should be avoided, which are discussed in Geberth’s article, Seven Mistakes in Suicide Investigation (2013). Mistakes in doing any death investigation affect the integrity of the evidence in determining the cause of death and in its admissibility in court.

In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene
“Anthropology is the science which tells us that people are the same the whole world over - except when they are different.” Nancy Banks Smith, british television critic. Anthropology is the study of what makes us human and how/why we interact the way we do. Anthropologists take a broad approach to understanding the many different aspects of the human body (site). More specifically, forensic anthropology is the examination of human remains for law enforcement agencies to determine the identity and cause of death in unidentified bones. Although being a real forensic anthropologist is not quite like being Temperance Brennan from Bones, there are many needs and uses for forensic anthropologists in not just the police force, but even in military
The two men thought of the event as a forgery from early on. With the doubt Oakley had, he performed a chemical analyses on the bone fragments and exposed the whole fraud, showing that not a single bone from Piltdown discovered was authentic. It was discovered that the jaw bone found was actually from a sub-fossil orangutan and the skull discovered was from a modern human who had a thick skull, thought to be from an Australian aborigine. The bones had been stained with potassium dichromate to make them appear older. Other bones were treated chemically to change the calcium phosphate to gypsum, or calcium sulphate. But who would to this and
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensics Anthropology is the study that goes beyond the human skeleton. A forensics anthropologist can find out. How a person lived, the food that person ate, and the overall make-up of a human. The use of forensics has grown in recent years, it is used to solve crimes and locate missing persons. Snow, (1982) Forensics anthropology is not a new science. The first case forensics anthropology was used on was the Jezebel case, dating back to the nineteenth century. This case involved a person, who was thrown from a window. Snow, (1982) The remains found in this case were the skull, feet, and the palm of the victim’s hands.
Forensic dentists have played a major role in the identification of remains in mass disasters, in crime investigations, in ethnic studies, and in the identification of decomposed and disfigured bodies in situations such as fire and car accidents (1). Teeth are considered to be a great form for identification as teeth are mostly composed of enamel. Enamel is the hardest tissue in the body and can withstand extremely harsh conditions (1). Two forms of dental identification of humans exist. These two forms are comparative and when no ante-mortem (before death) dental records are available. The comparative form of identification compares the ante-mortem and post-mortem (after death) dental records (1). Dental records con...
