Forensic Entomology

In this short story, "Grub," Goodyear discusses how to eat insects the right way, and also grouped by this category is when she talks about the specific types of bugs that people can eat. She says that people around the world eat crickets, worms, beetles, mealworm, ants, butterflies, bees, maggots, termites, tarantulas, grasshoppers, caterpillars and slugs. There are several different ways to prepare these insects. For example, people roast crickets, and if they are pinheads before they get cooked and, then people place the crickets

During this stage, which occurs 20 to 50 days after death, all the remaining flesh is removed, after this period and the body dries out. It has a cheesy smell, caused by butyric acid, and this smell attracts a new suite of corpse organisms. The surface of the body that is in contact with the ground becomes covered with mold as the body ferments (What Happens to the Body after Death 1). The body is flat and looks dried out. It eventually can leak through any soft tissues as decomposition progresses. Larval blowflies, flesh flies and houseflies, all called maggots, are abundant in this stage due to the semiliquid environment (Stages of the Human Decomposition Process 1). There is no definite event, such as bloating or purging, that separates stage three from the later, drier stages of decomposition (Stages of the Human Decomposition Process

While the thought of a giant farm full of decaying bodies may seem gruesome and terrifying, everyday it helps us learn new things about forensics. Firstly, The Body Farm was made known to the public when famous crime novelist Patricia Cornwell published a book with the same name about the farm (“Dead” 2). This book gave The Body Farm the recognition in more of a public eye. Patricia even states in the foreword of The Body Farm of how she came to learn about the farm and Dr. Bass, and how it changed her life. The Body Farm is an outdoor classroom designed to teach forensic anthropology students, and professionals in the legal and medical field, how the body decays and how the world plays a role in it (Drinnen 1). This farm not only benefits one type of science, but many all combined together, which is what forensics is made of. Police also use this to test and find how a body died in order to solve a case. The background behind the Body Farm is vast and important to our knowledge of the human body, whether we realize it or

Forensic anthropology is a subfield of physical anthropology that aims to assist in the identification of human remains and to help determine what happened to the remains (Ubelaker, 2006). A forensic anthropologist is able to aid law enforcement by narrowing down the list of possible victims. This subfield of anthropology consists of several processes and a vast list of duties that are important in providing positive identification.Even though forensic anthropology dates back many years, major advancements in this field are still being made today.

After that they “analyze bones to determine the victim's biological profile” as it is said in “What is Forensic Anthropology” by R.U. Steinberg.

A dead body that has been exposed to the elements such as water, air, temperature and weather, will decompose quicly and will attract much more insect activity. Colder temperatures slow decomposition, while warmer temperatures rather speed up the process of decomposition. If a body is available to insects, than the insects alone can reduce a fully fleshed body to skeletal bones withing a two week time period. Key factors to consider are: temperature, availability of oxygen, cause of death, trauma, humidity or wetness, rainfall, body size and weight, clothing, the surface where the body was resting, and the foods/objects inside the digestive tract of the

Each insect has some sort of lifespan, each part in that life span shows a significant appearance change. The age of these insects progresses as intervals of time pass on. By using the known age and time interval, a forensic scientist will be able to find out when a person may have died. This will not show exactly how that person died, however it does show how long that person has been dead. Using this forensic scientists can apply this knowledge to murder cases in order to help provide clarity and maybe even a verdict in the case at

At this point the decomposition rate decreases, as decomposition fluids and insects have vacated the body. Though the rate of decomposition decreases, it continues to occur until all that remains are bones.

The art of forensic entomology is used in identifying a timeline for how long a body may have been in the trunk due to the types of insects found ("Forensic Analysis of the Casey Anthony Trial - Crime Museum", 2017). This is because different insects are attracted to the various chemicals given off a body as it decays.Investigators also discovered and tested hairs found in the trunk ("Forensic Analysis of the Casey Anthony Trial - Crime Museum", 2017). Unfortunately, these hairs were only able to be used to narrow down who they may have belonged to as they contained no roots or connective tissue ("Forensic Analysis of the Casey Anthony Trial - Crime Museum", 2017). As we have learnt the hair in that state wouldn’t contain nuclear DNA to give a precise identification(Library.C, 2017).

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”.

According to (Goodman, n.d.), If a body is buried in a coffin deep underground, the decomposing process could take up to 50 years compared to bodies that are exposed to elements such as bacteria, water or air, then it will decompose a lot faster and very dramatically. No family member or stakeholder for that matter will donate their decomposed family member to her project for practice.

On December 11, 2008 skeletal remains of a young child were found by an utility worker. By the time the worker had discovered the remains it had went through 5 stages of decomposition. The 1st stage starts when the person dies (Csanyi). The 1st stage consists of enzymes in dead body cells start breaking down tissues which is known as autolysis. While this is going on bacteria in the digestive track start to eat the intestines. The 1st stage is called the fresh stage which can last for 1-2 days, unless of course the body is in a hot and humid area (Csanyi). Also at this stage chemical released start to attract flies. The 2nd stage that the body went through is called the putrefaction or the bloated stage (Csanyi). As the internal bacteria form the intestines start to enter the rest of the body, it causes the body to fill with gasses and as this happens the body begins to swell. The smell that comes from this stage is what attracts egg laying insects most of which are blow flies (Csanyi).

To the reader it may seem that with this introduction, the book will only be based on what uses a corpse has in science, but in later chapters the book shifts to what has happened to cadavers in the past and other endeavours cadavers have endured, such as cadavers that were used by the military, “Taking shape in the the rifle's’ sights would be men, a series of them, naked and unarmed. That they were naked and unarmed was the less distinctive thing about them. More distinctive was that they were already dead. They had died of natural causes and had been collected--from where is not revealed-- as subjects in an Army Ordnance Department experiment.” (Roach, 131). Cadavers have also been useful in car safety, “Over the past sixty years, the dead have helped the living work out human tolerance limits for skull slammings chest skewerings, knee crammings and gut mashings: all the ugly violent things that happen to a human being in a car crash.” (Roach, 87). Roach covers many things that have happened and that will happen to a person’s body once the person has passed

After the prior four stages, the body then enters the final stage of decomposition. In this final stage, the body is left with very minimal skin and complete bones; also known as complete skeletonization. When the body has reach the complete skeletonization stage, weather begins to affect the bones. If the body is in hot climate weather, the bones will begin to dry up and discoloration of the outer surface of the bone. Also factors that affect the human bones in this stage are insect and animal activity. For instance, the book states that squirrels specifically show a preference on human dry bones that have exposed up to one year to the environment. Thus squirrels are one type of animal that prefer the human bones because bones can inherit soil, and other substance from the environment depending on its location(Tersigni-Tarrant, Shirley, p. 352, 2013.) But the longer human bones spend out in their location, the more changes it is bound to exhibit. For instance, bones may exhibit additional discoloration and may resemble and growth with plants if it were

A segment of the Forensic Science in the Criminal equity organization that the vast majority acquainted with these days, however, few individuals know how this particular science came to be. Overall, legal science is intended to utilize experimental standards to clarify obscure parts of a wrongdoing. Through the utilization of uncommon tests and lab gear that permits researchers to recognize decisively different parts of a bit of confirmation in an illegal behavior. On the off chance that you occupied with finding out about how this procedure came to fruition, you have to peruse the recorded data underneath. Here is a brief history
