Criminal Justice Forensics & DNA

Words: 1257 Length: 4 Pages Document Type: Essay Paper #: 22805746

At the time that yrd was tried in 1985 DNA technology was not capable of forensic analysis of biological evidence however; in 1997 a comparison was conducted of yrd's DNA with the bodily fluid in the rape kit that had been collected at the time of the incident resulting in yrd's exoneration for this crime. The importance of proper preservation of biological evidence is highlighted in this case and not only for the purpose of obtaining a conviction but also for the purpose of ensuring that the wrong individual is not charged, found guilty and sentenced to prison for a crime that they did not commit.

Forensic Pathology: Forensics and DNA

DNA is part of the building blocks of human life and individuality: "DNA is present in nearly every cell of our bodies, and we leave cells behind everywhere we go without even realizing it. Flakes of skin, drops of blood, hair, and saliva all contain DNA that can be used to identify us" (Norrgard, 2008). DNA has long been a major part of forensics testing used in criminal cases for over forty years. "At its inception, DNA testing could only be performed by laboratories with molecular diagnostic capabilities" (Calaluce, 2010, p.2). The controversy surrounding DNA testing that made it more heavily scrutinized when it first debuted largely revolved around the fact that it was considered a "soft science" and that DNA evidence was viewed as simply not as reliable as other types. However, this controversy has since been eliminated: and there is absolutely no valid…… [Read More]

Forensic Chemistry Forensics Is a Very Important

Words: 1230 Length: 4 Pages Document Type: Essay Paper #: 88348926

Forensic Chemistry

Forensics is a very important part of a crime scene investigation. There used to be a time when murders or crimes were left unsolved due to the lack of evidence. However with the advances in technology and research in forensics, crime solving has become a lot easier. The branch of science, which helps out in finding out important evidence, is known as Forensics Chemistry. Forensics Chemistry employs methods, which help in finding clues, which couldn't be found in any other circumstances. We can simply call it the application of a brand of chemistry at the scene of a crime. This is a science which helps us investigate chemical substances and can help trace the cause of the death of a human being by finding useful evidence. However it's not important that the crime scene may be a site of murder or theft. It could also be due to…… [Read More]

Conclusion

The research showed that DNA evidence can be a valuable tool for the criminal justice system, but the effectiveness of such evidence depends on a number of factors. Among the more salient of these factors was the need to ensure that the DNA sample is collected and stored properly, and that it is transported to a testing facility in a timely and appropriate fashion. Other issues that emerged from the research included the need to maintain a strict chain of custody for all DNA evidence, as well as the need to ensure that the results of DNA testing were interpreted in an informed manner. Finally, the research was consistent in emphasizing that although DNA evidence can help prove innocence and guilt, the accuracy of such evidence depends on the type of DNA testing protocol that is involved and how these results are used in the…… [Read More]

Forensic Case Study Enrique Camarena the Abduction

Words: 1293 Length: 4 Pages Document Type: Essay Paper #: 79150009

Forensic Case Study

Enrique Camarena

The abduction of Enrique Camarena

The abduction of Enrique Camarena presents numerous interesting and unusual features regarding the gathering of forensic evidence. Many of obstacles that arose over the course of the investigation can be traced to the fact that the DEA Special Agent was apprehended in Mexico, where U.S. laws about preserving evidence did not apply. The Mexican police force (at least at the time of the abduction in 1984) was much more prone to corruption and bribery by persons engaged in illegal drug trafficking than U.S. law enforcement. ather than seeing to assist the DEA in bringing the murderers of Camarena to justice, the Mexican police often acted as obstacles, not assistants.

The real perpetrators of the murder of Camarena concocted a scheme with certain select members of the Mexican policy whereby Camarena's body (and the body of Capt. Alfredo Zavala, a Mexican…… [Read More]

Forensic Nursing in the Past

Words: 2240 Length: 8 Pages Document Type: Essay Paper #: 87651556

atchen (2005) defines the components of the nursing process as the client, the environment, the definition of health, and the definition of the nurse's role. Another trend in healthcare to be addressed is the reduction of enrollment in Registered Nurse (RN) programs, which has led to a shortage of trained nurses. This trend is important because the role of the forensic nurse has changed as a result of the increase in a nurse's range of function, with the rise in the number of the elderly due to improved healthcare systems and the introduction of community-based preventive projects.

In the future, the role of the forensic nurse may become more specialized and considered a separate profession from the registered nurse. According to the Federal ureau of Health professions, in 2000, the National supply of registered nurses was estimated at 1.89 million, while the demand was projected at 2 million, a shortage…… [Read More]

Hair is also in contact with chemicals in shampoos, and any dyes, gels, sprays or other cosmetics that may be placed on the hair (11).

Since there is no standardized method for cleaning these external contaminants off of the hair prior to analysis, the potential for inaccurate results from external contamination is widespread. There is no way to tell in the laboratory if a chemical is contained within the hair, and therefore came from with in the body, or if it is on the surface of the hair and did not come from within the body (12). An enormous amount of scientific research studies have indicated that hair analysis is unreliable as a diagnostic tool in crime solving. For example, in one study, the researchers took hair from the head of a single individual and sent portions of the sample to six laboratories; the results varied widely from laboratory to…… [Read More]

Ethical Pros and Cons of Criminal DNA Data Banks

Words: 1532 Length: 6 Pages Document Type: Essay Paper #: 84593917

Ethical Pros & Cons of Criminal DNA data banks

DNA banking of criminal information is a source of controversy among many human rights activists. According to statistics, Criminal DNA databanks offer an effective means of controlling crime. Genetic information on criminals is being collected and stored in many states as a means of identifying current and future criminals. Statistics support the notion that collecting DNA information on criminals helps reduce crime. Case in point, the Division of Forensic Science has managed an average of 37 "hits" per month, where hits refer to a situation where DNA analysis of a crime scene has resulted in suspect matches from previously convicted offenders and subsequent arrest (DCJS, 2004). In Virginia the DNA databank database contains more than 200,000 of criminals (DCJS, 2004).

Proponents of DNA banks argue that DNA identifying information should be collected on larger segments of the population to better control…… [Read More]

Filtration-Based DNA Preparation for Sexual

Assault Cases. Journal of Forensic Science 9/2003 Vol.48, No.

The precision of DNA technology allows law enforcement authorities to definitively identify perpetrators of sexual assaults from microscopic amounts of their

DNA collected from victims using a cotton swab. It has enabled the FBI to establish the Combined DNA Index System ("CODIS"), a nationwide DNA data bank and identification system modeled in principle, after the AFIS automatic fingerprint identification system.

It is estimated that crucial DNA evidence collected in approximately half a million unsolved rape cases awaits scientific processing, partly because of the complexity and time consuming nature of technical aspects of the techniques involved. The U.S. House of Representatives has already passed legislation in the form of the DNA Sexual Assault Justice Act that would allocate a quarter of a billion dollars to the problem. The Senate is expected to do likewise.

Forensic Toxicology in the 21st Century Courtroom

Innovations in forensic technologies in recent years have introduced a wide array of powerful law enforcement tools that can be used to help identify criminal perpetrators and establish the credible evidence needed to convict them. As a result, today, forensic toxicologists play an increasingly vital role in the criminal justice system where the need for accurate and valid evidence is paramount. To determine the precise role and importance of the forensic toxicologist today, this paper provides a review of the relevant peer-reviewed and scholarly literature, followed by a summary of the research and significant findings concerning these issues in the conclusion.

eview and Discussion

In 1866, Mendel discovered that there are "recessive" and "dominant" traits in plants, paving the way for understanding how genes work in predictable ways, and plowing the ground for later science, although his work wasn't "discovered" until 1900. In 1944, three scientists at the Rockefeller Institute in New York discovered that DNA is the carrier of the genetic information within the body.

In the early 1950s, scientists were by now aware that DNA was genetic material and that is was an acid made up of sugars, phosphate groups, and "equally matches bases," the Dolan center points out. That was all well and good, but the big question remained: HAT AS NATURE'S GENETIC CODE?

The man most responsible for "breaking the genetic code" was MARSHALL NIRENBERG in 1961; but "breaking it" (or identifying it) was only part of the puzzle. And then in 1965, NIRENBERG (working at the National Institutes of…… [Read More]

Using DNA to Solve Cold Cases

DNA Cold Case

Using DNA to Solve Cold Cases

Our federal, state and local law enforcement agencies are charged with the responsibility of bringing justice to every case that comes before them. Especially in the case of homicide, the importance of finding resolution through identification and prosecution (where possible) of perpetrators, is a top priority. This is true even as a considerable amount of time lapses since the emergence of a given case. hen an investigation reaches an impasse, exhausts its leads and ultimately finds itself without a trail to follow, it becomes a cold case. Cold cases typically find their way to the backburner as law enforcement agencies focus on solving crimes with more immediately available evidence. It is thus that cases go 'cold,' leaving investigators with no apparent directions to turn for resolution.

However, today, with the emergence and continued refinement in use of DNA evidence, many cold…… [Read More]

Understanding the structure and function of DNA has allowed scientists to uncover truths about the origin of human life on planet earth. In "Ancient ussian's DNA Sheds Light on Neanderthal Interbreeding," Dunham (2014) discusses one of the recent discoveries in human genetic history. A DNA sample was extracted from the tibia of a Homo sapiens called "Kostenki man" because of the village in which the skeleton was found. Because so much is now known about DNA, it is possible to take samples from 37,000-year-old skeletons. The article also shows that DNA remains intact in the bones of living creatures thousands of years after they die. Moreover, the article is about the fact that the DNA samples from Kostenki man show that some 50,000 years ago, Homo sapiens had interbred with Neanderthals, who had "colonized the region thousands of years earlier," (Dunham, 2014). As a result of these findings, researchers…… [Read More]

In the same way that traditional techniques of criminal identification have enabled law enforcement authorities to establish national fingerprint information databases for the purposes of connecting evidence to possible previous offenders, DNA-based forensic evidence has allowed the creation of similar databases greatly expanding the types of forensic evidence used to increase the security of sensitive facilities and restricted areas.

When combined with the ever-increasing power of modern computer technology to cross reference and match different types of physical evidence, law enforcement authorities have already developed the ability to establish terrorist watch lists incorporating forensic evidence of previous acts of terrorism with uniquely identifying features of perpetrators still at large. The continued evolution of such marriages between criminal forensics and identification techniques will greatly enhance homeland security, both at checkpoints and in terms of tracking the possible whereabouts and activities of persons of interest in connection with possible terrorism.…… [Read More]

The problems and future of DNA Testing

The scientific soundness of the DNA test has not been doubted at all. Courts have increasingly relied on the outcomes of DNA tests. The common man is at a loss to understand the complexities of the method, and as a result in jury trials it is not taken as standard proof but approached with hesitancy. Jurors are ignorant of science and the 'principles of modern genetics' and can get quite confused by all the jargon and confusing tactics of lawyers who are more interested in their cases rather than scientific truth. ("DNA Fingerprinting and Forensics," 2006) Thus the very process that can throw light on the proceedings and produce unfaultable evidence gets mired in sticky debates. The actual concern about the DNA test is not a confused jury but the process of collecting the data and analyzing it. There is no…… [Read More]

The term "forensics," though, can be applied to a number of different fields; however, all of these disciplines share a common feature in that their work products are specifically used in courts of law or for other legal issues that can mean the difference between life and death in many cases. According to Black's Law Dictionary (1990), the term "forensic" means "belonging to courts of justice," while "forensic engineering" means "the application of the principles and practice of engineering to the elucidation of questions before courts of law" (p. 648). Genetic forensics refers to the diagnosis of otherwise unknown biological material based on analysis of proteins or DNA; this branch of forensics has resulted in hundreds of death row prisoners being freed after they were exonerated through…… [Read More]

After completion of standard measurements and photographs of the victim, the hands were separately bagged to preserve any evidence contained thereon. Subsequent forensic examination and analysis disclosed organic evidence in the form of human skin and blood identified as originating from the same source as the other blood and tissue samples as those not associated with the victim. Thirty-six strands of hair, subsequently positively identified with the victim were recovered from the external clothing, as well as nine strands of human hair not identified with the victim.

Inorganic Evidence Collected:

Shoe imprints were preserved in standard casts and subsequently identified as originating from a size-12 Timberland® men's workboot. Minute quantities of blood were also recovered from within the prints before casting but of insufficient quantity to determine type other than being from a human source.

Death Penalty Support of the

Words: 1717 Length: 5 Pages Document Type: Essay Paper #: 52067091



The Death Penalty should not be considered as something that people desire, but as a form of punishment whose purpose is to deter crimes from being committed. Those who support this form of punishment believe that this is the only way that society can make sure that people who consider committing serious crimes can be stopped. There is a strong sentiment that those who commit the kind of crimes that would warrant the death penalty should not be put into prison for life. It is believed that this still presents these people with the opportunity to offend again.

Christopher Vaughn Case

Words: 1739 Length: 5 Pages Document Type: Essay Paper #: 42166029

Forensics

On June 14, 2007, a man covered in blood waved down a passing motorist on Interstate 55 in Illinois. He had gunshot wounds in the arm and leg. It was 5:40 in the morning in Channahon Township, Illinois. Nearby, the man's 2004 Ford Expedition carried the dead bodies of the man's wife and three children, ages 12, 11, and 8. They had all been shot to death. After pulling over, the motorist phoned 911, and the man was rushed to hospital. It was Christopher Vaughn, 32-year-old cyber crime and computer security investigator.

The police questioned Vaughn in hospital. Vaughn's initial statement revealed an outlandish story he would cling to during the course of his defense. Vaughn claimed that his wife asked him to pull over, then suddenly pulled out a gun, shot at him, killed her three children, and finally shot herself dead. The police did not believe Vaughn…… [Read More]

Crime Scene and Discovery

Never before has egregious police incompetence hindered the apprehension of a serial killer as in the case of Jeffrey Dahmer. When police were called to investigate an alleged domestic disturbance between Konerak Sinthasomophone and Jeffrey Dahmer on May 27, 1991. Although two women came to the aide of Sinthasomophone and urged police to look further into the alleged dispute, the police ignored their pleas and Dahmer was able to convince them that Sinthasomophone was his 19-year-old lover; if police had bothered to check Sinthasomophone's identification they would have seen that he was in fact only 14 years old (ardsley, n.d.). Having convinced the police that Sinthasomophone and he were in the midst of a lovers' quarrel, Sinthasomophone was released into Dahmer's custody and by the end of the night, Sinthasomophone would become Dahmer's 13th victim (ardsley, n.d.). Dahmer would proceed…… [Read More]

Since the work relates to scientific study, a scientific temperament and better equipped laboratory is a must. For each section of the system dealing with major and minor investigations, appropriate equipments, modern electronic gadgets and data processing systems must be provided and they must also be upgraded frequently. The personnel must be trained in the use and proper management of digital forensic laboratories and high technology crime detection and investigation. These must be installed and maintained on turnkey approach. One suggestion is to contract a company which has experience in setting up the lab and turn over the installation to them.

Crime Scene and Discovery

When the police were called to search John Wayne Gacy's home in Des Plaines, Illinois on December 13, 1978, they were not aware that their investigation into the disappearance of fifteen-year-old Robert Piest would lead them to uncover some of the most grisly murders committed in the United States (Evans, 2007). Piest was last seen leaving a pharmacy where Gacy, then working as a contractor, had recently completed a remodeling job (Office of the Clark County Prosecuting Attorney, 2012). Three hours after his disappearance, his mother, Elizabeth Piest, notified the Des Plaines Police Department and Lt. Joseph Kozenczak was tasked with leading the investigation (Sullivan & Maiken, 1983, p. 7; ell & ardsley, n.d.). During his initial investigation, Lt.

Green iver Killer

In 1982, the remains of a number of young women started to show up in the area surrounding Seattle. These women were all relatively young and shared a lifestyle, prostitution and street life, that made them easy targets for a killer. Before the slayings officially ended in 1998, a total of 42 women would be thought to be potential victims of the Green iver Killer with the potential for many more being added to the list. Some believe that as many as 90 women may have been murdered by Gary idgeway. idgeway eluded police for almost two decades, even though he was a suspect in several of the disappearances, and was finally caught as a result of DNA evidence garnered from some of his earliest victims.

Fingerprints

Improving the Science of Fingerprinting: A Literature Review

Fingerprints are one of the most commonly employed tools that we have in investigating crime. This powerful forensics methodology has contributed to the solving of countless criminal cases and has been used as convicting evidence in courts of law. However, as this literature review shows, even the use of fingerprints is in a state of evolution as we gain ever greater and more accurate tools in the struggle to investigate and solve crimes.

At the outset of the discussion, the text by Neumann (2012) helps to dismantle the notion that fingerprints are infallible as a way of drawing identity. According to the research provided by Neumann, fingerprints achieve a certain statistical probability that makes identity matches likely but not certain beyond a doubt. This finding helps to underscore the critical imperative of continuing forensics research, such that we may come in…… [Read More]

Genomes and Comparative Genomics

Over the last decade we have achieved rapid strides in the field of genetic engineering. The study of molecular biology has been fairly advanced mainly aided by the unprecedented growth in information technology. Today bio-informatics has opened new vitas for us and we are already progressing in investigating and in the comparative study of genomes. This has shed new light up on our knowledge of the evolutionary process and the important concepts such as protein folding and selective expression, which have so far eluded our understanding, are beginning to unfold. Let us have a brief overlook of the subject.

At the same time, there is a different element introduced in the pursuit of forensic science that is not dealt with in other branches of scientific inquiry. As the question of justice is also central to any forensic proceeding, the suspect's account of events and/or hypothesized explanations for observations must also be taken account (Young 2009). In this way, both verification and falsification can be used during experimentation.

Before these experiments take place, however, the predictions must lay out a way to clearly identify the expectations of the experiments, as well as a way the methods by which they should be conducted. Several predictions can usually be made rather quickly after the hypothesis that are fully testable and easily determined. Based on hairs found at the crime scene, for instance, it could be predicted that skin found under the victim's fingernails was of the same DNA as the on-matching hairs…… [Read More]

Inheritable neuropathies are among the globe's healthcare challenges today. Although their incidence is not as high, one in every 2500 people, as compared to other major healthcare problems, their symptoms, and consequences are equally fatal. Charcot Marie Tooth disease is among the inherited neuropathies, which has significantly shown potential and fatal consequences to people. Notably, the disorder does not have any known cure, but there are numerous therapies to control the disease. Although this is the current case, advancements in medicine, are gradually bearing fruits because experts have discovered a way to diagnose some types of these deadly disorders. Other types of neuropathy disorders include hereditary neuropathy with liability to pressure palsy (HNNP), hereditary motor neuropathy (HMN), and hereditary sensory and autonomic neuropathy (HSAN or hereditary sensory neuropathy).

" This category of identifiers, is however, weak. There are apparently a list of indicators such as name and address that have to be removed from the database in order to use the DNA evidence without notifying the person. When these markers are removed, the evidence is considered public. Yet there are potentials for those markers to resurface and privacy can never be ensured. Even though Angrist is in favor of a public pool of DNA evidence for the lofty goals of science, he agrees, "de-identification is increasingly difficult." It is becoming hard to disconnect names, dates, and places from the hemoglobin and NA.

Desiccation Tolerance in Prokaryotes

Desiccation Tolerance in Prokaryotes

Water is very important for life. Indeed, the processes of life, both external and internal even, at the cellular and the molecular level, are governed by water. Without water, most living organisms suffer from what is known as water stress.

This water stress can be due to the loss of water or dehydration. Desiccation is a special case of dehydration where drying takes place in air. Alternatively, another form of water stress is due to the excessive accumulation of salts. This is relatedly called osmotic stress. Osmosis seeks to reduce this accumulation by moving fluids across a concentration gradient. While most living beings cannot survive without water, lesser species belonging to the eukarya group -- that includes both bacteria and a more primitive organism archaea show remarkable tolerance to water stress.

Responses to water stress takes place at a supracellular level as well as a cellular…… [Read More]

While black men can be incredibly diverse-looking, she may focus on those features that tend to differentiate them from white men. This is a risk in any cross-racial identification, where someone may notice differences from their own ethnic group, but fail to look beyond those features that stand out as "other" in his mind, which makes any person in that racial group a possible suspect.

In fact, it is impossible to overplay the role that misidentification has played in so many wrongful convictions. It is difficult for many people to realize that DNA evidence did not play a role in older convictions; the technology simply was not available. Furthermore, when DNA evidence first became available, it was a new technology that was not fully understood by all of the actors in the criminal justice system. In those early times, there were investigators, prosecutors, and fact finders who would believe a…… [Read More]

" Because of the ability to reproduce in large amounts in a small amount of time, phytoplankton are considered as the first link in the food chain of nearly all marine animals. Phytoplankton provide food for a large variety of organisms, including the microscopic animals (such as the zooplankton), bivalve molluscan shellfish (like mussels, oysters, scallops, and clams), and small fishes (such as anchovies and sardines). To continue the food chain, these group of animals then provide their own kind of food to other group animals like crabs, starfish, fish, marine birds, marine mammals, and humans (Karl, et al., 2001).

Proteins are often called the building blocks of life. In fact, the very word "protein" implies their importance in the body: it is a Greek word meaning "first place." Approximately fifty percent of the dry weight in animal cells is comprised of protein (Campbell 71). They play a roll in almost everything the body does and "are used for support, storage, transport of other substances, signaling from one part of the organism to another, movement, and defense against foreign substances." (Campbell 71). Proteins are essential to the proper functioning of every organism known to man.

The human genetic code holds the instructions for the making of over ten thousand different types of proteins; all with specific purposes. Additionally, "Proteins are the most structurally sophisticated molecules known." (Campbell 71). In comparison to other molecules, proteins are enormous and come in nearly every shape imaginable. However, despite their variety and size, proteins…… [Read More]

The article asserts that many crime labs have been cited for sloppy procedures and producing erroneous evidence (Morrison and Roane, 2005). The fact that crime labs are not required to be accredited adds to the problem because there are not any standard procedures that govern the management of the labs. Under new laws all federally funded crime labs will have to be accredited by 2006 but currently 30% of the federally funded crime labs do not have any accredidation (Morrison and Roane, 2005).

The article also reports that many experts such as crime lab technicians, coroners, forensic anthropologists and police chemists have been fired for presenting erroneous evidence in…… [Read More]

Michigan vs Tyler the Supreme Court Decided

Words: 1312 Length: 4 Pages Document Type: Essay Paper #: 33188754

Michigan vs. Tyler, the Supreme Court decided that "fire fighters, and/or police and arson investigators, may seize arson evidence at a fire without warrant or consent, on the basis of exigent circumstances and/or plain view"

This may only occur during the extinguishing operations or immediately after, otherwise a warrant or the owner's consent is necessary. This came as a response to an accusation of "conspiracy to burn real property," where the prosecutors had collected and used evidence of numerous days after the firefighting operations. The Supreme Court ruled in favor of the defendant, as evidence was collected without warrant in the subsequent days.

I think the process used by a gas chromatograph (heating, etc.) is not appropriate for separating sand granules and the gas chromatograph cannot identify sand grains as a substance. In my opinion, something like filtration should have been used to separate sand from the rest of the…… [Read More]

Criminal Justice System

Challenges of Mara Salvatrucha (MS-13) to law enforcement

Law enforcement agencies view the Mara Salvatrucha (MS-13) the most harmful street gang in the U.S. The aggressive nature of MS-13 members have led to a variety of killings and terrible beatings. Various trials held in New York and Maryland have led to significant jail terms even extending to life imprisonment for MS-13 members. The FBI was first attracted by violence, but proof of the gang's escalating level of organization has drawn public attention. Organization is an indicator of a future where MS-13 is will be a transnational network of criminals extending from the United States to suburban communities in a multitude of U.S. towns (Mandel, 2013).

Despite functions of violence, it is worrying to note that MS-13 movement is improving its structure and organization. Many major security experts are comparing it to the illegal groups of the 50s…… [Read More]

Authors present the results of a national law enforcement technology survey and comparable forensics technology survey that was conducted by the RAND Corporation to assess the effectiveness of this support and constraints to applying forensic technologies at the state and local level. Authors devote several chapters to different types of forensic analyses, including what types of techniques are best suited for various types of crimes and the evidence that may be present. A discussion concerning the types of evidence, including controlled substances, firearms, explosives, fire debris, bullets, footwear, vehicle tire marks, latent fingerprints, blood, gunpowder residue and so forth that are typically encountered in different crime scenes is followed by a useful description concerning how and why specific forensic technologies are used. Authors also present a description concerning how computer-based technologies are facilitating the application of these forensic investigatory methods to achieve higher conviction rates by providing improved testing results.…… [Read More]

19-21.

Authors are all forensic scientists who present a timely discussion concerning the harmful effects that extended exposure to the environment can have on forensic evidence, including its analysis and the interpretation of test results. Because crime scenes may produce less-than-optimum samples of DNA, blood and other molecular-based evidence based on environmental factors such as sunlight, rain, and microorganism growth, authors provide a review of the relevant literature to explain how these constraints must be taken into account when conducting forensic investigations and analyses. In particular, authors emphasize that biomolecular substances such as enzyme and DNA analyses are adversely affected by these environmental factors. While these biomolecular materials may remain amenable to forensic analyses over time if they are properly stored and maintained, extended exposure to environmental elements can cause them to degrade in ways that confound even the most sophisticated technologies. Authors also present a discussion concerning how both biological and non-biological samples are affected by exposure to environmental factors, and how toxicological tests to ascertain time and cause of death can be hampered by these effects. Authors point out, though, that it is possible to interpret the results of forensic analyses of even degraded biological samples if forensic scientists are cognizant of the processes these samples tend to undergo as they degrade. Although some types of samples such as paint chips and glass fragments may not be adversely affected by extended exposure to the environment, other substances such as volatile ignitable liquids tend to evaporate altogether, making time of the essence in gathering evidence and conducting suitable testing protocols. Authors also emphasize, though, that there remains a dearth of timely and relevant guidance in the literature concerning the interpretation of biological samples that have experienced extended exposure to these environmental elements and call for additional research in this area. Taken together, this journal article presents useful guidance for forensic scientists who are confronted with degraded samples as a result of extended exposure to the environment, and note that the nature of crime means that these types of samples will be far more common in forensic scientists' experience than the pristine samples with which they may have been trained.

e should be thankful for this amazing technological development," (Hatch, 2000).

The death penalty must be altered, not abolished. In all new cases, if DNA evidence is not provided as conclusive for the conviction of the arrested, then capital punishment should not even be a consideration. There are already appeals processes in place for those who presently serve on Death Row, and in many of these cases, the inmates have pleaded for DNA testing. This should be executed on a case-by-case basis, pending the jurisdiction of the local judicial system. It was found in the research for this analysis that many of the authors who approve of using DNA testing for exoneration, oppose DNA evidence that has been presented during the time of trial. Much like those who oppose the death penalty and those who support it, there will be continued debate over this new science, which is offering legendary…… [Read More]

Rule: Any out-of-court statement offered to prove the truth of the matter asserted is generally inadmissible as hearsay. (801-802) However, hearsay may be admitted, in a prosecution for homicide or in a civil case, if the declarant, while believing the declarant's death to be imminent, made the statement about its cause or circumstances. (804(b)(2).

Application: Here, the defense attorney's objection is premised on the fact that the deceased Sam's statements are I inadmissible as hearsay, as an out-of-court statement by a person unavailable for trial, offered to prove that the other driver was driving on the wrong side of the road. However, Trooper Jones may offer this statement because it falls under the (804(b)(2) hearsay exception, as a statement in a civil case that the declarant made while his death was imminent.

With the advent of technology, there are other tests apart from Blood Type present to rule out a crime. If today, the assailant's blood type does not match the blood on the crime scene, it does not necessarily prove him guilty. Forensics studies have indicated that there are two types of people on this planet regarding secretion of ABO proteins in body fluids. There are the secretors, and then there are nonsecretors. In cases of rape, the fluid usually tested is semen. The thing to note is that if that person is a secretor, only then his blood antigens will be present in the semen. If the semen is negative for any antigen that can either mean that the person is type O or is a non-secretor (Lyle, 2011) Furthermore, there are thousands and millions of people who have the same blood type.

Genetic Screening

Words: 2160 Length: 6 Pages Document Type: Essay Paper #: 55745991

Genetic screening is one of the most controversial topics in the scientific arena today. The advent of the Human Genome Project, which maps the complete human genetic code, has brought this issue to the forefront. This paper will discuss the basic science that underlies genetic screening, applications of genetic screening, and investigate some of the common misconceptions and ethical questions about its use.

Genetic screening itself is simply "the systematic search within a population for persons possessing particular genotypes, which are either associated with disease, predisposing to disease, or leading to disease in descendants" (Miller). In simpler terms, genetic screening involves testing and determining whether "an individual's genetic material to predict present or future disability or disease either for oneself or one's offspring" (McCarrick). Essentially, genetic screening is conducted for several basic reasons, including the care of the ill and the prevention of disease, providing reproductive information, determining the incidence…… [Read More]

When Madeleine McCann's parents put her down to sleep and went out to eat with friends while on holiday in Portugal in at a tapas bar approximately 50 meters from their apartment, they never thought that their 3-year-old daughter would be snatched from their room. While the McCann's immediately reported their daughter's disappearance to Portuguese authorities, massive procedural errors including failure to secure the crime scene, contaminating the scene, and failure to collect evidence have impeded efforts to locate or determine if Madeleine was alive at the time of her disappearance. Portuguese and Scotland Yard continue to probe into Madeleine's disappearance six years after her disappearance as new evidence and eyewitness testimony surfaces.

Without a body, how would investigators be able to bring Ian Simms to justice? When Helen McCourt disappeared on February 9, 1988, investigators interviewed several individuals near the George and Dragon pub in Billinge, Lancashire who reported hearing screams and loud noises coming from Ian Simms's apartment. When investigators approached Simms's, they sensed something was wrong based on Simms's behavior and fabricated stories. Simms's behavior prompted investigators to impound his vehicle where they collected evidence tying him to McCourt, and which later allowed them to further investigate his home, which they found was bloodstained indicating that a violent and deadly struggle had taken place and that Simms's involvement in McCourt's disappearance was undeniable. Over the next few weeks, clothing and other items belonging to McCourt and Simms would be found along the banks of nearby rivers, which were analyzed and connected to Simms via dog hairs, carpet fibers,…… [Read More]

There are arguments as to how realistic these representations on the screen are in regards to real life experiences and this is what we aim to discuss in this paper with a focus on the television series, ?Dexter, ? which is still running almost eight years after its first appearance on screen. We will be focusing on what appears more realistic in regards to how forensic science is presented in the series while also directing the focus on Hollywood's distinct trademark. We will also look at how such TV series may influence real life and affect people's expectations.

Human life is playing its vital role in moving the world to a secure place where families, businesses, trade, educational system, media, governance, art and science thus all fields of life is affected by the security concerns (Sen, 2002). Now the big question here is how technological development can contribute towards the security concerns especially in the areas of biometrics, forensics and physical security.

That is simply because individual in the same family are much more likely than unrelated individuals to share similar foundational experiences by virtue of their exposure to similar parenting and resources in their immediate environment throughout their early lives (Gerrig & Zimbardo, 2007; utter, 2006). Just as hesus monkeys tend to adopt maternal behaviors and elements of personalities of their mothers irrespective of their genetic inclinations, so do human infants and growing children and adolescents internalize and adopt various aspects of the behaviors and reactions exhibited by their parents and other significant adult behavioral role models in their lives (Gerrig & Zimbardo, 2007).

This dearth of scholarly is due in large part to the events and themes that are the focus of the historical record. In this regard, "History was written mainly by men and about men's activities in the public sphere -- war, politics, diplomacy and administration. Women are usually excluded and, when mentioned, are usually portrayed in sex-stereotypical roles, such as wives, mothers, daughters and mistresses. History is value-laden in regard to what is considered historically 'worthy'" (Women's history, 2012, para. 3).

The first of the forensic impressions I selected for my analysis consisted of footprints. "Impressions occur when two objects come in contact with one another, and one object leaves behind distinguishing markings on or in the other" (Gaensslen & Larsen 2013: 213). A footprint is classified as an impression because it has depth (three-dimensional character) in material space (Gaensslen & Larsen 2013: 213). "A positive impression is identical to the object that made it, whereas a negative impression is its mirror image. The shoe prints left in the mud are negative impressions; they are negatives of the shoes' soles. In this scenario, the positives would be the shoes' soles" (Gaensslen & Larsen 2013: 214).

As noted, Graysmith also had an explanation for how the Zodiac might have disguised his printing, but clearly the letters have not been linked to anyone for certain. The fact that the Zodiac stopped killing has been the focus of a good deal of speculation as well, including that he could be dead, that he might be in prison for some other crime, or that for some unknown reason he just stopped. No one really knows the answer to this question, either. A killer in New York later used the name Zodiac and even claimed to be the Zodiac, but that has been discounted by most observers.

Political Influence Over Stem Cell

Going back further, the same religious principals also inspired opposition to organ transplants and blood transfusions; before that, the Catholic Church strictly forbade any forensic scientific research, necessitating the need to dissect cadavers for medical education entirely in secret (Levine, 2008).

Just as the news media are partially at fault today for their failure to distinguish legitimate concerns from ludicrous fears in connection with the ongoing political debate over American healthcare, they are equally responsible for allowing unfounded fears of "human cloning" in connection with the beneficial uses of stem cell science. Specifically, the main source of secular opposition to stem cell research is attributable to unnecessary fears of rampant misuse of human cloning technology to clone human beings. While human cloning is hypothetically possible, no responsible scientific researcher would ever misuse current biomedical technology in that fashion. The complexities of cloning entire organisms have been well documented in animal…… [Read More]
