a. Edmond Locard created the Locard’s Exchange Principle. Locard stated …show more content…

Livor Mortis is when the heart stops pumping and the blood begins to settle in the parts of the body closest to the ground. The skin will appear dark blue or purple in those areas. The skin will not appear discolored in areas where the body is restricted by either coloring or if an object pressing against it.
c. Algor Mortis is the postmortem changes that cause a body to lose heat. The process by which the body temperature continually cools after death until it reaches the room temperature. The rate of heat loss is influenced by factors such as the location and size of the body, the victims clothing, and weather conditions.
6. What is Forensic Odontology?
a. Forensic Odontology helps identify victims when the body is left in an unrecognizable state. They will take the teeth of the victim, as the characteristics of teeth, their alignment, and the overall structure of the mouth provide evidence identifying a specific person.
EVALUATE: I believe that I have an overall good understanding of the chapter. There may be a few, small ideas talked about in the text that I will need to revisit. One of the ideas that I will need to revisit is the history section of the chapter.

The first topic in the chapter was about the definition of Forensic Science and how the current definition came to be. Next, it jumped into the history of Forensic Science. It talked about each of the people that contributed to Forensic Science. The book also explains how those people contributed to Forensic Science. A couple people that the book talked about was Alphonse Bertillon, Leone Lattes, Hans Gross, and Edmond Locard. Since Locard was talked about, the book also talked about the Locard’s Exchange Principle, which simply states that if you come in contact with an object or another person a cross transfer of material will be made. Next, the book brought up the organization of the crime laboratories. It stated that approximately 350 public crime laboratories operate at various levels of government, and can vary in size ranging from one person working to more than one hundred. Another thing that is talked about in this chapter is the different types of crime laboratories units and what they do. The units range from biology to voiceprint analysis. Chapter one also talked about important court cases. These court cases included Frye v. United States and Daubert v. Merrell Dow Pharmaceuticals Inc. This chapter also explained what the difference between Rigor Mortis, Livor Mortis and Algor Mortis is. Lastly, the chapter talked about the number of specialized Forensic Science services

Comparing simple techniques simply to retrieve a piece of evidence is completely different as we learn more about the science and learn from the mistakes made in the past. Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly

In 1996, Peter Neufeld the cofounder of the Innocence Project remarked that there is no rational as why crime laboratories, which habitually make decisions that have life and death outcome for an indicted individual, should be less managed than a clinical laboratory operating alike tests. In addition to this The NAS Report commented on the lack of standards for lab management and administration. For example, it argues that ‘There is no uniformity in the certification of forensic practitioners, or in the accreditation of crime laboratories. Indeed, most jurisdictions do not require forensic practitioners to be certified, and most forensic science disciplines have no mandatory certification programs. Moreover, accreditation of crime laboratories is not required in most jurisdictions.

In this paper I will be comparing contrasting two various aspects of forensic sciences used, and talking about the different tactics used to identify suspects; as well as the contrasts between the two methods. The man I will be talking about is John Wayne Gacy. The two methods I will be going over are, Finger print DNA and Forensic toxicology. These two are very similar, but made substantial differences in the evidence in his case. John Wayne Gacy was a murderer from Chicago, Illinois.

End of Life care This important documentary does not come close to doing justice to Gawande 's video: Being Mortal. The book is rich with excellent examples of doctors, nurses and family members doing their level best assisting others to live the fullest and richest lives possible right up until and including the very end of their lives. As Dr. Atul Gawande would say, the point isn 't to strive for a good death but rather to have the best possible life that is congruent with one 's own values; and to make medical decisions and choices accordingly. By living each day in harmony with one 's goals and values, one is likely to have a good death.

Forensic science has been an aid to the law enforcement community for years now. It has solved cases that were unsolved years before DNA and science started to play a role with cases and law enforcement. The case of Samuel Reeves and James Layne was unsolved in the year 1989, this was considered a cold case because it had been years since they found who the murderer was. This case was considered a crime of passion, where it first started off by kissing and having the same attraction towards each other, but when James Layne started to get aggressive and not respecting Reeves decision to not have sex, that was when things got hectic. Forensic science helped this case by the use of fingerprints, they found the fingerprints in a bottle, and when

In 1892, a young woman named Lizzie Borden was accused of murdering her father and stepmother (“Lizzie Borden on Trial” 2). This accusation was influenced by the lack of evidence at the scene of the crime. There appeared to be no murder weapon, very few witnesses, and the house did not show any signs of an intruder (“Lizzie Borden on Trial” 5). Once the scene was investigated, it was determined that the cause of death for both victims was multiple blows to the head by an axe. Two axes were found in the home, and neither had a speck of blood (“Lizzie Borden on Trial” 14).

Basic scientists are individuals who prefer to study occurrences in order to gather a better understanding to satisfy their curiosity. This process doesn’t resolve in answering the question but rather gaining the knowledge (Greene & Heilbrun, 2014). The basic scientists’ role in law enforcement is to conduct “research on the relationship between social attitudes and behavior can clarify why people obey or disobey the law” (Greene & Heilbrun, 2014). This predation is transferred to the courtroom through testimony and

Some of the overlapping areas of the subfields of anthropology are that forensic anthropology and osteology are connected because a forensic anthropology relies on processes that osteologists use to determine how an individual died, weather it was from diseases, natural causes, or other causes. Forensic anthropologists used the same methods when human remains are found in an archeological site, forensic anthropologists determine if the remains are recent or the remains of a hominin. Another overlapping area would be primate paleontology and primatology. These two subfields are similar because on focuses on the habits, environment, and lifestyles of fossilized primates while the other subfield focuses on the behavior patterns of primates and how they differ from the behavior of humans and other non-human primates. It is important to understand humankind from a holistic perspective because it will show how humans developed and evolved and adapted to their environments

The former being defined as the evidence collected in order to convict or rule out suspects, and the latter being defined as the way the investigators developed the investigation and how it evolved throughout the ensuing years. In order to evaluate these two different subjects, one needs to examine the similarities and differences between this investigation and theories about how investigation of this type develop, the nuances of this investigation not able to be explained by theory, investigatory elements that

“Forensic anthropologist usually works in three broad categories,” said Texas State professor Jerry Melbye.” A Forensic Anthropologist help examine a human skeletal or decomposed remains in a legal setting to establish the identity of an unknown individual and to help determine the cause of death. A Forensic Anthropology work to find the individual that was murdered or was a homicide. They need to find the biological profile of that person.

The term “post-mortem examination” refers to any form of examinations that are carried out after death. While necropsy (look at the dead) and autopsy (see for oneself) are also used together with post-mortem examination, the word “autopsy” is more accurate in matching the procedural aim: to observe the body directly than to depend on disease indicators like signs and symptoms. Forensic medicine, on the other hand, comes as a subset of medical jurisprudence. It involves retrieving and analysing of medical evidences from samples to formulate objective information in legal usage.

The educational path required to achieve my goal of becoming a forensic scientist will be a long, exhausting process. The different characteristics of forensic science- like the use of analytical techniques- is what sets itself apart from just any other science degree(Thorpe). Being just a junior in high school, KEES money plays a major role in helping me decide where I go
