At the autopsy, samples are taken of body fluids such as blood, urine and the fluid that surrounds the brain. Again, this is principally designed to establish a time of death; claims have been made that changes in the chemical construction of these fluids can be used to measure the time since death, but as the rate of changes depends upon body temperature they have not been established. Moreover, the cause of death (whether natural or unnatural) and physical or emotional stress can effect the rate of change too. There is one bodily fluid that can give an indication of the time of death of a fairly recent victim: the vitreous humour, the jelly-like interior of the eye. After death, the potassium content of this fluid increases steadily over four or five days. The drawback is that no-one
To record a crime scene, forensic scientist can use photography, drawings, and videography. Photographs are an important record of the unaltered crime scene, Drawings or sketches provides valuable information when a photograph cannot accurately depict the scale of a room or the relationship of items to each
In this paper, I will discuss the background of forensic pathology, the pros and cons of forensic pathology, and the similar and different in a forensic pathologist and a coroner. There are various disciplines in Forensic Science that can help with a crime, and solving that crime. One of these various disciplines is Forensic Pathology which the study of disease, and its causes, moreover; it involves the discovering the cause of the death where a death is sudden or suspicion to law enforcement. While a Forensic Pathologist can be helpful to law enforcement, and helpful in assisting in crime investigation, there are cons to being forensic pathologist. Furthermore, forensic pathologist can be confused with coroner even though they do the same

In the Casey Anthony case Jeff Ashton who is a former state attorney in Orange county Florida, and also the first prosecutor in the United States to get a conviction based on DNA decided to use a new Forensic method in the Anthony case. The smell of death would be the allowed as evidence for the first time ever. In the trunk of Anthony’s car was a stained area on the carpet and an odor. Ashton stated that the smell was that of human decomposition. That piece of carpet was removed, sealed and sent to Dr. Vass, a forensic anthropologist at Oak Ridge National Laboratory. Dr. Voss has been studying human decomposition at the University of Tennessee’s “body farm”.
This caught my attention right away and hooked me in. Along with being a topic I was quite interested in (reference to last nonfiction book report), the first two sentences got me wondering. What could be told from a murdered person’s body? I already had a lot of background information from research and watching shows on mystery and homicide but this question led to a million answers. Some answers were cause of death, manner of death. time of death, weapon used, etc, all of which were related because this was sparked from the thought of a dead person and my ideas. From this, I read on to determine what could be told from an expert’s point of view.
This conclusion lines up with what the textbook states about determining a time of death. The textbook lists many factors that can affect body decomposition including temperature, rainfall, and humidity (Lyman 284). Obviously it would be extremely difficult if not impossible for investigators to factor in all these variables given the fourth months between when the body was dumped until it was found. This makes it clear that investigators could not truly determine an exact time of death.
Forensic science has come a long way from where it was less than 100 years ago. It has only been relatively recently that the advancement of technology we use, has occurred. The Body Farm, an institute in Knoxville, Tennessee, is a place where dead corpses are left to rot and then studied on how the body decays in different circumstances. Death’s Acre: Inside the Legendary Body Farm tells about the farm from Dr. Bill Bass’ point of view, from the establishment of the farm, to the impact in the world of forensic science the farm has caused. David Pitt and Alynda Wheat offers their insight into the book in their reviews. The Body Farm has been a monumental stepping stone to the advancement of modern day forensic sciences. Dr. Bill Bass, is making
Through a little research on the internet, a website called “Bodies Revealed” informed me of the process used to preserve the bodies, which is known as “polymer preservation.” The bodies that are used first are embalmed according to standard procedures and perfused with a preserving agent to prevent the normal tissue decay that takes place after death. After the body is embalmed, a trained dissector prepares it, or a part of it, according to predetermined guidelines. Because of the degree of difficulty involved in dissecting a full body specimen, it can take several months to complete. If the dissector is working with individual organs, they can be prepared much more quickly. After the dissection is complete, the specimens are thoroughly rinsed in cold running water, which removes as much of the preserving agent as possible. Rinsing a full-body specimen can take up to one week to finish. After the rinsing, the specimen is ready to be dehydrated. They dehydrate the specimens by placing it in acetone, which acts to replace all of the tissue water present in the specimen. The specimen is then impregnated with a mixture of liquid silicone polymer and a crosslinker. The polymer hardens during a curing process, which leaves a dry, odorless specimen that doesn’t decompose. I had the
Forensics has to do with crimes and usually trying to investigate or find out what happened or who is responsible for the crime. Seeing that in our day and age there is a lot of violence and killings, this career path is a wise decision. Since it is very common to hear about a shooting or something closely related to that, the family is most likely going to want to know what happened, so then an investigation will arise. People are going to gather up the evidence and figure out who is the guilty one. There are many careers in forensic science today like a crime scene investigator or a DNA analyst but I’m mainly going to focus on autopsy technicians.
A post mortem change is the term used to describe any changes which are observed in a subject after death has occurred. Post mortem changes which may be observed in a cadaver include algor mortis, rigor mortis, liver mortis, post mortem blood alterations and subsequent clotting, purification and autolysis (Unknown, 2013). However, histological tissue samples may undergo a series of alterations which causes alterations in tissue structure to occur. Alterations in tissue structure may encourage disparity between expected staining and the subsequent reactions to
In the novel, Chronicle of a Death Foretold by Gabriel Garcia Márquez, he examines the scene of the autopsy done on Santiago Nasar. During this scene, his body is then to be further dishonored and desecrated. The reason why Márquez places this scene in the book is to further emphasize the fact Santiago Nasar is dead. He places each individual in the autopsy room to basically show the damage they have indirectly caused. Therefore, this body is the result of the actions of each person. By not speaking up or by just forgetting to warn Santiago resulted to the slashed up body lying on the table in front of them. This scene is the time and place for each individual to have a direct look at the mess they could have prevented and to reflect. Unlike
This truth forms an essential link between the enforcement of law and protection of the public in the administration of justice.” Forensic pathology is clearly a crucial role in the justice system. You have to be a little weird and crazy to have a passion for the kind of work that the coroners and M.E. go through on an everyday basis. They use past knowledge to make decisions on how death occurred and they come across many different postmortem changes in dead bodies. Every field is important in forensics, but pathology advocates for truth and justice to dead
The word autopsy derives from the Greek word autopsia, which means “the act of seeing for oneself” (Autopsy 1). An autopsy purpose is to “determine the cause of death, observe the effects of disease” (Autopsy 1). Human dissection was frowned upon until after the Middle Ages. The first human dissection was performed in 300 BCE by Herophilus and Erasistratus, two physicians who were studying disease (Autopsy 2). In the late 2nd century CE a Greek physician Galen of Pergamum was the first
Time of death can be determined in a few ways. Body temperature can be a great indicator of when someone died. Each hour a body is deceased, a certain temperature decline happens. However, if the body was exposed to an extreme climate it can be thrown off. Which stage of rigor mortis can also be used since it happens within about thirty hours of death. Lastly, insects can be used as an indicator by which ones are on the body and what stage of life they’re in. (Claridge,
