Case Study Of Forensic Entomology By Benecke And Lessig

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

Mason is a twenty one (21) month old baby who was found dead in his home with his body scared, bruised, clad in nothing but a vomit and faeces stained singlet. Two days before his death, Mason was visited by Child Safety Officers and was not in the home with the mother during this visit. He is said to have been a few streets away, where he had been left with the mother’s boyfriend. He became known to Child Safety a few months prior to this when a report was made as a result of neglect concerns.

Firstly, eggs were collected from the eyes of Scomberomorus niphonius and disinfected in 1% sodium sulfite solution for 3 min, and subsequently in 3% Lysol brand disinfectant for 5 min. The disinfected eggs were then transferred to sterile vials to clone. Secondly, third stage larvae of Lucilia sericata were selected to be placed in 3.5% formalin for 5 min, 2% hydrogen peroxide solution for 3 min, and then 5% dilute hydrochloric acid solution for 5 min. After the two-step disinfection, the larvae remined vigorous. A hundred randomly selected larvae were proven to be aseptic by bacterial culture test.

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”.

Within 5 years of Baer’s groundbreaking work, over 1000 American, Canadian, and European surgeons were using maggots in their practice.10 Many hospitals operated their own insectaries for rearing and disinfecting the larvae.

When the infective larvae on the pasture are eaten by the sheep they develop in the 4th stage larvae and become adults. This stage is called the host stage as they need to live inside a host (the sheep) or the worms will die. They live inside the sheep’s abomasum during which they lay eggs and will spend the rest of their lives and the whole cycle repeats itself

The article “Flies’ Feet Can Spread Bacteria” explains how Pathogens and Bacteria can be spread by flies’. Scientists experimented on houseflies and blowflies in which their laboratory experiments prove that flies can pick up bacteria on their legs and then deposit the microbial bacteria elsewhere. In addition, many scientists believe that flies can contribute to the rapid transmission of pathogens and outbreak situations. In other words, flies may be associated with the transfer of bacteria in outbreaks of diseases. These flies mostly stay around places with trash and sewage. For example, many of the test flies were in Brazil where the acquired bacteria from sewage and transferred to other locations. The flies’ legs are the most crucial factor

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

Four stages of this parasite have been identified the first stage is the penetration phase which is day 1-17 during this stage the larvae moves into the body of the animal and moves to the lungs. The second stage which is the prepatent phase which is day 8-25

Roaches, beetles, and maggots crawl across the floor and into the decaying meat that lies on the ground. The sound of footsteps are heard from the distance, startling a few of the bugs that infest the space. The doorknob begins to turn and the door slowly opens. The flies charge towards the opening and overwhelm the rest of the abandoned building. The police officers at the door are immediately hit with a wall of an unimaginable stench. It tickles their noses and their faces start to contort and cringe. They force themselves to look towards the room and look down at the decomposing carcass. Most of the flesh has been eaten away from the body and all that remains is a skeleton with tissue and fat falling off its very bones. The face of the once live human is gone and unrecognizable. The police officers try to search the scene for any evidence of identification, but no wallet or driver’s license is found. With no identification, the police officers are unable to compare dental records or conduct DNA analysis to identify the deceased. Law enforcement has a valuable tool available to them to aid in the identification of the remains, which is forensic facial reconstruction, or forensic facial approximation. On the one hand, there are researchers who believe that forensic facial reconstruction is a sound and accurate method in identifying an individual in confluence with other physical evidence. But,

Forensic science consists of a variety of fields such as in this case Forensic Pathology, Toxicology, and Biology were used to help solve the murder. Forensic Pathology was used to determine the cause of death by conducting an autopsy on the Johnson body. Coming to a conclusion, that Denise Johnson’s cause of death was due to asphyxiation (also known as strangulation)2,9. The pathology unit also determined that her death was a forced and violent death. Given the facts of how the victim died it provides the officers with an idea on how the murder was committed. Secondly Forensic toxicology is the use of toxicology, pharmacology, clinical chemistry and analytical chemistry to help legal and medical investigation of poisoning, death, and drug use. A drug test was conducted on Johnson’s body in order to evaluate the type and amount of illegal or legal drugs that were taken. A drug test can normally detect all prescription drugs, and as well as alcohol and illegal drugs such as, cocaine, heroin, morphine, codeine, antidepressants and phencyclidine. According to Johnson’s toxicology reports, the only drug found in her body was heroine9. Lastly to have a better understanding of the case, it was important to know what had happened to Denise. Therefore the forensic biology unit conducted a rap kit to determine if Johnson was sexually assaulted. The forensic biology division is responsible for applying their biology knowledge to the law enforcement, which also includes forensic

This paper has been generated with the purpose to provide observational, opinionated, and researched information regarding the pathology of death and a simulated case-study to which a victim’s remains are observed for postmortem clues in an effort to determine time of death. This paper will address how I, as a student, observed details to formulate a time of death, what my observations provided to determine if the death would be ruled a homicide or an accident.

From fictional shows like CSI Miami to real life crime scenes, we have all seen the process it takes to gather forensic evidence. If you haven’t, research has been recently gathered to come up with new and innovative ways to catch a criminal. Whether it be from derelict fields, dark alley ways, or deep sea oceans, many environments can leave behind physical evidence ofn a criminal and victims that crime scene investigators both real and fictional can use to identify and catch the culprit. However, this can be difficult when trying to find the best pieces of evidence to use and detect after analyzing and putting criminal information together.

Because they look identical on both ends, Magizoologists have tried looking for eyes in order to distinguish the head from the tail. However, so far they have been unsuccessful which has lead them to believe that Flobberworms are blind. Flobberworms also have no teeth, so Magizoologists are not able to distinguish between the holes used for eating and waste removal - without watching the creatures. It is unknown how a Flobberworm looks on the inside, due to their rapid decomposition.

G. spinigerum has a many host life history. The first intermediate host is a small fresh-water crustacean, a cyclopoid copepod (Prommas and Daengsvan, 1933). The eggs hatch in fresh water and water fleas of the genus Cyclops eat the larvae. The water fleas are eaten by small fish. The larvae end up in the stomachs of carnivores. The larva pierce through the stomach wall and relocate around in the host's body for about three months before returning to the stomach and attaching itself in the gastric mucosa. It takes six months to mature. The eggs are carried in the host's feces. If they reach fresh water then the cycle begins again. Paratenic hosts are an important part of the life cycle, and it has been found that the advanced third-stage larvae
