Forensics: Signature Analysis
Forensic examination and analysis of writer identification and verification are reported as having "applications in various domains. Especially in the field of biometric recognition. Forensic Document Examination (FED) is a process that clarifies the writer of a handwritten document. Applications included are signatures verification. FED is such that is reported to have been based primarily on manual examination by experts with only recent automation of analysis methods being initiated.
State of the Art Systems
Two state of the art systems presently exist to "address the tasks of writer identification and verification" and include: (1) the system that uses Hidden Markov Models (HMMs); and (2) the system based on Gaussian Mixture Models (GMMs) to model a person's handwriting. (Sclapbach and unke, nd) In addition, there are reported to be "various feature selection methods applied to improve the performance of an existing off-line writer identification system. The performance of…… [Read More]
Forensic analysis has also been used successfully in many paternity cases. Furthermore, the advantages of Forensic DNA technology are extensive and have been employed in forensic fields such as the detection of bacteria and various other pollutants in water and in the matching of recipients in organ donor programs.
It should also be noted that forensics is a field that covers many areas and fields of knowledge and which can provide careers in a number of related disciplines. One of the careers in this discipline is that of a medical examiner. This requires a medical degree and specialisation in forensics. A forensic odontologist specializes in dental forensics, while a crime laboratory analyst usually requires a degree in chemistry.
A crime scene examiner analyses the crime in any situation, whether indoors or outdoors. This specialization is possibly one of the most interesting but involves direct contact with crime victims, which can…… [Read More]
Forensics, Law, & Psychology: False Confessions
It is a well accepted law in the forensic field, that only recently slipped through, that investigations can be helped by compelling people to confess. However this forensic law that encourages and enables forced confession spirals off methodological research in psychology that shows that such confessions can be harmful to the field since many prisoners end off confessing under duress and admitting to actions that they actually never perpetrated.
More than 80% of criminal cases are settled by a coercive confession (Zimbardo, 1967) and indeed, Dr. W. Sargant said that without confessions convictions may be reduced by about 70%. Confessions are an accepted part of the forensic scene and an "attractive way of solving crimes" (cited in Brandon & Davies, 1973). However, many confessions are elicited under duress -- an acceptable law in forensics -- and consistent empirical research shows that this may well…… [Read More]
This phase is described by Carrier as the phase where we "...use the evidence that we found and determine what events occurred in the system" (Carrier, 2005).
2.2. The United States Department of Justice's (USDOJ) digital forensic analysis methodology
The second methodology under review in this paper has been put forward by the United States Department of Justice. This consists of four basic phases: collection, examination, analysis and reporting (Shin, 2011). More specifically, stages of this digital forensic methodology are comprised of the following central aspects. Firstly, there is the obtaining of the data, followed by the forensic request; the preparation and extraction phases; identification and finally analysis and forensic reporting leading to case level analysis (DIGITAL FOENSIC ANALYSIS METHODOLOGY).
The preparation and extraction phase is characterized by the examiner's question as to whether there is sufficient information to proceed and to ensure that there is sufficient data available to…… [Read More]
He noted the uneven pattern, which he knew would make a match easier.
Crime library's Kathleen Ramsland writes in the Most Famous ite Mark,
"In his expert testimony, Souviron described the bite mark on Lisa Levy as the jury examined the photographs. He pointed out how unique the indentation mark
was and showed how it matched the dental impressions of undy's teeth. He showed them the structure of alignment, the chips, the size of the teeth, and the sharpness factors of the bicuspids, lateral, and incisor teeth. Then he put up on a board an enlarged photo of the bite-mark and laid over it a transparent sheet with an enlarged picture of undy's teeth."
There was no question that Ted had made the bite marks on Lisa Levy's body. The photos would be the biggest piece of evidence the prosecution had linking Ted to the crime (ell).
Finally, the chief…… [Read More]
From the onset, it is important to note that in criminal investigations, one type of evidence commonly encountered is hair evidence (Oien, 2009). As Oien further points out, "during the course of the normal hair-growth cycle, hairs are readily lost from individuals, and these hairs may be transferred during the course of a criminal activity." The hairs collected from the seat of the car in the scenario recounted could have, therefore, been transferred during the commission of the said criminal activity. However, the hairs could have come from either a human being or an animal. In that regard therefore, further analysis and comparison would have to be made to determine their origin.
To begin with, in my analysis, I would start by examining the medulla. According to Merck (2012), while the medulla of animals is particularly thick, that of humans is characteristically thin. I would also expect…… [Read More]
126). Finally, both genders of offenders are likelier to marry criminals or antisocial individuals than are non-offenders (Cauffman, 2008, p. 125).
Female offenders differ from male offenders in a number of striking aspects. Though both genders suffer from abnormal brain activity, female offenders tended to have developmental brain patterns with more right frontal lobe activity, similar to non-criminal males, while male offenders tended to have no differences in the activities of either brain lobe (Cauffman, 2008, p. 127). Also, while poor parenting highly influences both genders of offenders, it seems to have a more pronounced effect on female offenders than on male offenders (Cauffman, 2008, p. 128). In addition, though both genders have a high degree of victimization in childhood, females tended to be victimized more often and report being the actual victim (Chesney-Lind & Pasko, 2004, p. 25) while males tended to report witnessing the victimization of others (Cauffman,…… [Read More]
Thus, the link between mental disorders and criminal behaviors is more complex than the simplistic question would assume. If the question must be answered with a clear yes or no, then the answer would be no: criminal behavior is not in and of itself a mental disorder. Criminal behavior can be used as a warning sign to test for mental disorders, and then that would allow psychologists to treat the underlying cause of the criminal behavior. As Cauffman (2008) puts it, "effective prevention efforts should target the mental health needs of at-risk females before they lead to chronic behavior problems," (p. 119).
Some criminal behaviors are not indicative of mental illness because they are acts arbitrarily defined as crimes. When Dr. Martin Luther King, Jr. was put into a Birmingham jail, he wrote a letter that describes why some laws are unjust and simply meant to be broken. It takes…… [Read More]
The two paragraphs are very different, not only in tone, but in the style of writing. The first paragraph is a peaceful letter which expresses gratitude whilst the second paragraph is very angry and critical. They are also very different in their length, where the first paragraph was very concise and straight to the point. However, both paragraphs seem to share the topic of marital or family issues. Because of their different writing styles, I believe that the two paragraphs were written by two different people.
At first, after I read through the two paragraphs, I believed that they were written by the same author. However, after much analysis, in my opinion, the two paragraphs are written by two different people. I initially thought that they shared the same author because of the last line in the first paragraph, and the first line of the second paragraph. This is…… [Read More]

Harris (2005) states that if anti-forensic methods are to be successful "...they must rely on inherent problems with forensics. Anti-forensics often makes use of attacks on the investigators and may also take advantage of our dependency on specific tools or processes. Inherent physical and logical limitations of the investigative process and world in general can be exploited as well. Since anti-forensics rely heavily on the forensics process being susceptible to these issues, resolving these concerns would theoretically solve the anti-forensics problem. Unfortunately, we…… [Read More]
The DNA and fingerprints matched to a particular suspect would provide verification that the suspect had handled the gun. It would also rule out any other suspects if no other DNA or fingerprints were found on the weapon. Last but not least would be any traces of blood found on the suspects clothing. Blood evidence is very powerful evidence since current technology allows for establishing identities through the analysis of blood that is very effective. George Schiro, a forensic scientist with the Louisiana State Police Crime Laboratory writes, "a blood source can now be statistically narrowed down to one person out of several million or even several billion" (Schiro). Most importantly, according to Schiro, blood evidence can eliminate prospective suspects while providing strong evidence in regards to establishing identities of other suspects. All four of the above mentioned evidence types can provide helpful evidence for the prosecutor(s) and often times…… [Read More]
Such evidence could be invaluable in attributing criminal activity related to such a business to someone in particular.
Additionally, efforts were made in the United Kingdom to utilize aspects of saliva to aid in the usage of forensics for potential criminal investigations. Largely attributed to the vast numbers of attacks on truck drivers within Cardiff, drivers in that part of the world are now utilizing what is known as a "spit kit" so that they can retrieve a sample of saliva if it is exchanged during any sort of potential robbery or attack (Dobson 2011). The DNA garnered from this sort of methodology can prove very beneficial to forensics efforts in their attempts to find the attacker.
In terms of what the future for forensics DNA research and employment holds, it is more than likely that there will be a nearly universal adoption of the utilization of partial DNA matching…… [Read More]
Statistics can help describe these relationships by providing a new model or language to present difficult concepts where words often fall short.
Not all of statistical ideas make complete sense to me. One such concept is the idea of "significance." The Statsoft text introduced a revealing concept: " There is no way to avoid arbitrariness in the final decision as to what level of significance will be treated as really "significant." That is, the selection of some level of significance, up to which the results will be rejected as invalid, is arbitrary." It appears that significance as no truly objective value. This is ironic due to the fact that the whole purpose of research is to signify something.
The shape of the normal distribution curve being in the shape of a bell is also quite interesting and mysterious. Somehow, normality, as a quality, can now be identified through a pictorial…… [Read More]
Forensics and Digital Evidence
Forensics is a discipline which uses standardized techniques to pull apart an event, analyze what happened, and find a more accurate conclusion to the data analysis than just witness testimony. For centuries, lacking even rudimentary techniques like fingerprinting or blood type analysis, the legal system relied on confessions and witness testimony. We may turn to Ancient Greece for one of the first recorded examples of a type of forensic inquiry. In the anecdote of Archimedes, the scholar was asked by the King to determine if a crown made for him was pure gold or contained silver. It seems the King had supplied pure gold, but suspected the goldsmith of being dishonest. Archimedes had noticed that while bathing the level of the water in the tub rose. He surmised that different objects displace different levels of water. Using a mathematical calculation he determined during his famous "Eureka"…… [Read More]
Access Data Forensics Toolkit v. EnCase:
Digital or computer forensics is currently one of the rapidly growing and significant industries because of technological advancements. The growth and significance of this industry has been enhanced by the increase in digital crimes, which has contributed to the need for organizations to adopt quick and reliable tools to collect and offer digital evidence. Digital forensic teams need some items in the forensic toolkits regardless of whether these teams are part of the organization or law enforcement agency. One of the most important processes in computer forensics is drive acquisition, which must be a forensically relevant sound image i.e. flat file bit stream image. In addition, the process also requires volatile data in order to enhance the findings of the process. As digital forensics continues to grow and become important, there are various toolkits that have been developed including Forensic Toolkit (FTK) by AccessData…… [Read More]
Generally, forensics can be described as the process of using scientific knowledge in the gathering, evaluation, and presentation of evidence to the courts. Since forensics deal with the presentation of evidence to the courts, it basically deals with the analysis and recovery of hidden evidence. In this case, the hidden evidence may be in several forms including fingerprints, blood stains, and DNA evidence. On the other hand, computer forensics can be described as the discipline that merges fundamentals of law and computer science to gather and evaluate data from computer systems in forms that are admissible as evidence within the courts. These computer systems include wireless communications, computer networks, and storage devices. Computer forensics has emerged as a new discipline and field in the recent past due to the recent increase in cyber terrorism. Consequently, there is minimal standardization and uniformity across the computer forensics industry and the…… [Read More]
This means that no deeper view into the system and its underlying infrastructure is provided to the customer." The constant flow of information makes compiling a forensics report on any given item very difficult.
Legal issues may also hamper digital forensics in dealing with cloud issues. Cloud computing raises some unique law enforcement concerns regarding the location of potential digital evidence and its subsequent forensic analysis. When a savvy and knowledgeable customer or business becomes the target of a criminal investigation, they could migrate their working environment to a cloud environment. This would provide a means for the business to continue its routine operations while the migrated environment is forensically analyzed. The migrated data only represents a temporary snapshot of when it was sent to the cloud. Since the data can be stored anywhere in the world, its scattering could be to a location or country where privacy laws are…… [Read More]

Security forensic software tools
Security information and event management has experienced much progress in recent years and there are currently a great deal of software providers that direct their attention toward the field. Through analyzing security alerts, SIEM creators make it possible for individuals and companies to understand instances when they are vulnerable and address these respective cases. The SIEM industry concentrates on assisting users as they review their condition and as they search for a method to provide a response in cases when they take on attitudes that might put them in a position where they have a limited understanding of their options.
Logpoint is designed to address SIEM-related concepts by providing users with a less challenging opportunity to deal…… [Read More]
The issue at hand involves the examination of a scene from an office space within Widget Corporation. We find that this is the assigned office for a Mr. Didit. The information we have at hand is digital -- a photograph taken from an approximate distance of 3 feet from the occupant's desk. Using the photograph, we find that there are a number of electronic and non-electronic devices and our initial inspection finds an inventory made up of computers, keyboards, monitors, hard drives, a mouse, a digital box or receiver, a usb drive, a backup hard drive, cords and various office supplies and personal items (National Institute of Justice, 2008)

The rapid development of predictive routing algorithms that seek to anticipate security breaches are also becoming more commonplace (Erickson, 2009). Evidence acquisition through digital forensics seeks to also define preservation of all patterns of potential crime, regardless of the origination point (Irons, 2006). The collaboration that occurs in the open source forensic software industry acts as a catalyst of creativity specifically on this point. There are online communities that seek to define more efficient approaches to this area of evidence acquisition through collaboration of development efforts. Their results over the long-term are changing the use of forensic software, both from an open source and proprietary standpoint.
The authentication phase of gathering digital evidence centers on the integrity of the data captured and stored. This specific phase relies heavily on evidential integrity and authenticity of records (Barret, 2004) in addition to compliance to ISO 15489:1 (2001) a records management standard that…… [Read More]
For example, the main goal in the typical forensic science investigation would be to identify the source and full extent of a breach in security at some level and in which system it occurred; if sufficient evidence was found by forensic scientists to prove that a crime had been committed, the next objective would be to assist law enforcement in gathering the additional evidence needed for prosecution through careful coordination with the law enforcement authorities (Sartin, 2004).
Therefore, it is vitally important for forensics examiners to possess the same types of communication skills needed for comparable positions in the criminal justice field, plus some that may not be typical of the field. In this regard, Piazza (2003) reports that human resource managers are having a tough time recruiting and retaining qualified forensics personnel in almost every setting. This author provides the example of a Secret Service human resource manager lamenting…… [Read More]
DNA has improved the Forensics Field
As technology and science have progressed, DNA evidence and its use within criminal forensics and trials have become more prevalent. This is not to say that every case hinges on DNA evidence, or that every crime scene can be worked over in order to obtain a criminal's DNA, but the knowledge of this tool within the forensics realm has reshaped the way in which many investigations are conducted. DNA evidence has also acted to shed a new light within the trial realm, as experts in the field offer their opinions as to the efficacy and accuracy of such evidence. It is also being used to shed new light on old cases, helping people get out of jail and clear their names in many cases.
DNA was first used by authorities to help convict a murderer in England in 1984. In the U.S., it was…… [Read More]
Forensic Fabric Analysis
Some of the basic tools that a fabric examiner should at least have at any given moment include a stereomicroscope, along with a composite light microscope that is fitted with polarized light capability, and a comparison microscope. When examining both questioned and known fabric, the examiner must do this side by side, and within the same magnifications in terms of visible light. Alternative lighting, which includes fluorescent lighting and polarized light, is not necessary but when the equipment used allows, is highly recommended. In certain types of analyses, such as when testing for solubility, you may need to examine the questioned and known fabric near each other, and on one slide, or in the spot plate's wells that are adjacent to each other. However, you need to exercise extreme caution where loose fabric is concerned not unless you have no problem with identifying the source of each…… [Read More]
Assets in the investment portfolio were overvalued. Financial transactions were structured to report smaller amounts of debt and create the appearance of greater cash flow. Financial results were represented in a false and misleading manner.
Forensic accountants also played an important role in the Enron case by doing audits and investigating accounting practices to gather evidence of how the fraud was performed. They played vital roles in the court room in presenting the evidence against cross examination and scrutiny. The forensic accountants were highly valued for their objectivity in the way evidence was presented.
Accounting, auditing, investigation, business, and understanding human behavior enabled forensic accountants to gather evidence for prosecution of fraud in court cases involving fraudulent accounting practices. These are vital skills forensic accountants are required to maintain. Forensic accountants must maintain competency, due care, objectivity, integrity, confidentiality, and proper conduct at all times, whether working with a client…… [Read More]
Forensic crime labs are important institutions within the criminal justice system and each lab must be up to standard in order for this system to operate at a high and fair level. A good crime lab begins with a good design based on solid fundamentals and thorough planning. The purpose of this essay is to design a digital forensic crime lab that can be used in a university setting. In order to this, the essay will explain the budgeting process while keeping business objectives in mind. The next step of the design will introduce how the physical controls can be used to implement this design. Criteria for success will also be discussed as well as a suggested floor plan to house the lab.
The setting for this digital forensic lab is within a university setting which denotes that funds could most likely be attained for these purposes.…… [Read More]
Forensic Pathology as Scientific Evidence
Forensic Pathology is generally understood as having to do with the investigation of causation of injuries or death as a legal requirement. In the pursuit of this, pathologists usually investigate injury or death scenes and other relevant records to ascertain the cause of death.
Practically, forensic pathology incorporates the performance of post-mortem examination, which is an examination of body tissues and organs as well as investigations such as X-rays and toxicology testing. Forensic pathology makes it possible to interpret such results and reveal cause of end point of death as required by the law.
The results driven from forensic pathology are bound to be subjected to interpretations. The body can transform during the process of death or after, this transformation or changes are referred to as post-mortem changes or "artefacts," these changes can be misinterpreted as ailment or injuries that took place when…… [Read More]
Forensic Case Study
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]
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]
According to Elvidge (2014), the first record of the use of forensic entomology is Song Ci (Sung Tz'u), in 13th century China. However, using insects and arthropods like arachnids to aid in forensics investigations is a relatively new field, and one ripe with potential. The most notable applications of forensic entomology are in the identification of time elapsed since death, and the geographic location of death. When applying forensic entomology to homicide and other death studies, the specialist will take into account the various stages of decomposition. Forensic entomology can also be used to elucidate other types of crimes in which any type of decaying organic matter is a clue, in cases of human or animal abuse in which wounds have festered, in analyzing dried blood samples, in the investigation of botanical drug trafficking, and when detecting the presence of drugs in the deceased. Less glamorous but equally as…… [Read More]
Forensic nursing goes far beyond traditional medical care; it is "an innovative expansion of the role nurses will fill in the health care delivery system of the future," (Lynch, 1995, p. 489). This is why the Vice President of the United States Joe Biden has stated, "Forensic Nurses play an integral role in bridging the gap between law and medicine. They should be in each and every emergency room," (cited by the International Association of Forensic Nurses, 2006). Until recently, I was not aware that the profession existed. I learned what I know about forensic science from television, and also from years spent watching autopsies being performed at the morgue near by dad's office. Oddly, I would spend hours watching actual autopsies so when television shows started to depict forensic science in documentary and fiction shows more and more, the field broadened and opened up to me. I soon learned…… [Read More]
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]
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]
Usually, it is more likely that the ruse is discovered by a forensic psychologist, and/or that there is simply too much evidence pointing to the fact that the criminal knew what he or she was doing when the crime was being committed (Adler, 2004).
The Likelihood of eoffending
Whether a criminal is likely to reoffend is something else that has to be considered by forensic psychologists. They are often asked to give their opinion on this issue when inmates are coming up for early release or when they are eligible for parole. There are other factors and opinions that are taken into account, of course, but having a professional, psychological opinion about whether a criminal has been "cured" of his or her behavior or will be likely to repeat it is very significant (Adler, 2004; Dalby, 1997). It can be difficult to determine what goes on in the mind of…… [Read More]
The construction/validation sample of 96 juvenile sexual offenders ranged in age from 9 to 20, with an average age of 14. To administrate the exam, the test is not directly administered to the juvenile: instead the trained professional calculates the boy's relative risk factors, based up his past history, such as a history of violence, of being a victim of abuse himself, caregiver consistency, and history and preoccupation with sexuality. The problem with the test is that it to some degree stereotypes the boy and tries to predict the likelihood of negative behavior based upon negative past and family circumstances. However, it can be useful in family court settings for flagging 'at risk' teens who have already entered the system and may be helped by receiving additional social support to prevent future acts of violence.

Forensic Mental Health Legislation and Policies
The current position on forensic mental health issues when it comes to legislation and policies is a strong one, but there are some difficulties that do not translate well into the probation and parole policies that are currently offered. In other words, there are issues that are not being addressed, and that are allowing individuals with mental health problems who on are probation and parole to slip through the cracks and struggle with their issues on their own (Wang, et al., 2005). Not only are they not getting the help they need in order to live productive lives, they are also more likely to reoffend, violate their probation or parole, become homeless, drink to excess, do drugs, and get involved in other unsavory behavior (Patel & Prince, 2002). The high proportion of indigenous offenders is one of the biggest issues that indicates mental health…… [Read More]
It is thus that technologies which work to yield that crucial data from the memory store of any such device have become so valuable to law enforcement in the age of terrorism. According to the Computer Forensics Tool Testing Program (CFTT), "a cellular forensic tool shall have the ability to logically acquire all application supported data elements present in internal memory without modification" (Ayers, 15)
This is to indicate that such technology should be able to hack into mobile communication devices without detection by the subject, making it a valuable tool in investigating crimes and preventing suspected crimes. The evaluate of its requirements is produced by the CFTT, which is an organization that "provides a measure of assurance that the tools used in the investigations of computer-related crimes produce valid results." (Ayers, 6)
A major drawback of such technologies, and one that invokes a yet far more complex discussion concerning…… [Read More]
In the late 1990s, this was not a problem as the stock was continuing to climb to all-time highs. However, once the economy began to slow, is when this strategy backfired by forcing them to issues more stock to cover these losses. As shares were declining, many investors became weary of continuing to participate in these activities. (Healy, 2003)
In late 2001, these activities were brought to the attention of regulators and investors (which resulted in the eventual bankruptcy of the firm). This is illustrating how forensic accounts overlooked or ignored key areas that could have uncovered fraudulent activities. As a result, one could argue that the lack of ethics and the close relationship with company executives helped to perpetuate these abuses. (Healy, 2003)
Another type of fraud that is most prevalent is insider trading. This is when executives will have specific knowledge of the financial situation surrounding…… [Read More]
Alter the Forensic Dynamics during an Interviewing Process
In this paper, we reveal how professional's attitudes, views, and knowledge do not necessarily match forensic research findings. Witness issues will then be discussed concerning research community. The study identifies some of the key factors that can alter or improve forensic dynamics during the interviewing process. This study focuses primarily on forensic dynamics relating to the interviewing young children and the associated challenges.
Expert knowledge and attitudes
It has been proven that professionals and social researchers (biased) towards information confirming their initial beliefs by refuting established opinions. Once established, beliefs and impressions challenged to contrary proof. Thus, belief systems and generalization can create a confirmation prejudice that may result in faulty understanding and wrong presentation, adversely affecting important decisions. egarding child victimization situations, such prejudice may result in dramatic repercussions presenting a serious risk to a person's legal rights or presenting a…… [Read More]
Forensic and Clinical oles and Assessment
While psychologists and psychiatrists may engage in both clinical and forensic practice, it important to recognize that clinical and forensic practice are distinct areas of practice. This means that the role of the forensic and clinical practitioner differs in several ways: "who the client of the psychologist is the nature of the relationship between the psychologist and the individual being evaluated, and the psychologist's approach to the material provided by the individual" (Packer, 2008). Moreover, it also means that the professional assesses the individual differently. These differences include: the purpose of the assessment, the goal of the intervention, and psycho-legal vs. psychological assessment. While the differences may seem clear, the reality is that even forensic evaluations can lead to the establishment of the type of relationships that develop in clinical practice, making it difficult for health care professionals and for their clients to differentiate…… [Read More]
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
By definition, forensic toxicology is focused on providing scientific evidence for the courts. For example, Anderson and Volker (2008) report that, "The term 'forensic' is effectively a synonym for 'legal' or 'related to courts' and in Latin means 'before…… [Read More]

Our Agency has just received $3 million grant from the federal government because of the efficient method that the unit employs in running the department. Additionally, the City Council has agreed to continue assisting the unit with additional funding at the end of the three years provided the department is productive and serve the citizens well. However, the department requires presenting a different budget from the previous budget. This proposal will create a new budget for the forensic unit to describe where all the funding will be allocated. The budget will consider the specialized personnel for the unit because smooth running of the unit depends on the specialized personnel.
Mission Statement of the Specialized Unit
The specialized forensic unit will deliver highest quality forensic services to all our customers, and our unit will deliver accurate service through analysis and the state of art technology. We…… [Read More]
But on the other hand, a reader who is also interested in the subject doesn't have to necessarily enjoy the idea of decomposing human corpses - or have really thick skin - to get educated regarding the forensic science / anthropologic value of this book.
Being a student in Forensic Anthropology in fact makes it easier to get through the potentially offensive parts of the book, because there are many things to be learned from the novel. This book reflects real-life issues pertaining to forensic research and crime-related applications to forensic science. The book is dedicated to "All victims of murder, all those who mourn them, and all who seek justice on their behalf."
Bass's "Body Farm" is designed so that cases where bodies are found in similar circumstances may have a foundation in terms of the forensic police personnel being able to know how and when - if not…… [Read More]
forensic interviewing of rape victims. It addresses the often asked question to postpone the interview. That request comes from the victims and their families. This study provides evidence that it is important to conduct the interview with the victim within 72 hours of the attack.
On television, forensic interviewing is often dramatized to the point of being illegal. Interviewers on the big screen hit the interviewees, intimidate them, lead them and coerce them into providing the information needed to neatly wrap up the crime in the allotted hour. While this makes for good entertainment and it almost always leads to putting the bad guys away, it is far from realistic. In real life, forensic interviewing can be a tedious process that does not always bear fruit. Forensic interviewing is something that can help uncover valuable information or lead to a dead end. The key elements to how successful a forensic…… [Read More]
In "The role of the Violence isk Appraisal Guide and Historical, Clinical, isk- 20 in U.S. courts: A case law survey," Vitacco et al. discuss the use of the psychological forensic assessment in predicting future dangerousness. The authors are very critical of the use of psychological assessments for these purposes because of their belief, which is affirmed by investigation into case law, that psychologists often get their predictions wrong. In other words, psychologists are not necessarily able to predict future dangerousness, which can make an assessment of future dangerousness little more than guesswork.
One of the cases mentioned by Vitacco et al. was the seminal case of Barefoot v. Estelle, 463 U.S. 880 (1983). The defendant, Thomas Barefoot, was convicted of murdering a police officer. He was charged with a capital offense and the jury had to determine whether or not Barefoot was eligible for the death penalty.…… [Read More]

Forensic Investigation: Bullet Holes in Glass Lab
Bullet Holes in Glass
Glass broken through a projectile forms two distinct fracture types -- radial fractures and concentric fractures (Orthman & Hess, 2012). The radial fractures will often form on the glass side, on the opposite side of the impact, and will spread outwards from the point of impact (Hess & Hess, 2012). Concentric lines form after the radial fractures, on the same side of the impact, and will often encircle the point of impact (Woods, 2013). adial fractures terminate if they encounter fractures caused by an earlier projectile, which basically means that they can be used to determine the order or sequence of force, or rather, which bullet hole was created before the other. In cases where multiple shots are fired from the opposite sides of a glass surface say a window, forensic investigators will often need to establish the order…… [Read More]
Forensic chemistry is a branch of chemistry that applies the techniques and concepts of chemistry to provide evidence and testify in court. Some federal agencies such as FDA (Food and Drug Administration) and National Institute of Justice use forensic chemistry experts to investigate the crimes committed against the society, which include environmental pollution, food adulteration, and distribution of unsafe chemical substances. In the United States, cocaine and other illegal drugs can put society at risks. Thus, experts in forensic chemistry uses different processes to perform a laboratory test to identify the presence of substances. A chemical analysis carried out in the laboratory can help to detect illegal drugs, which will assist the police or other law enforcement agents to prosecute offenders in the law courts. (Drug Enforcement Administration 1).
Moreover, the forensic chemistry analyzes non-biological materials to detect a trace of evidence from the crime scenes to found unknown material…… [Read More]
DNC Forensics Workgroup Planning
It is the duty of this committee to set up sufficient security and forensic measures, while still ensuring "that the event continues safely and at the same time respect Constitutional rights, including freedom of speech and assembly" (Connors, 2007). Because of the highly controversy own nature of politics in the United States today, this will be a calculated effort. Undoubtedly, there will be issues with law enforcement dealing with protesters. The forensics task force must then be fully equipped to investigate any crimes committed sufficiently to produce evidence that can convict individuals later in a court of law.
To get started, it is important to understand what agencies are per feeding and how they will need to contribute their services at the time of the event. For planning purposes, it is important to set these responsibilities as early as possible to ensure that those responsible for…… [Read More]
skills that a forensic accountant needs to possess and evaluate the need for each skill.
Over the last several years, the role of forensic accountants has been continually evolving. This is because there have been a number of cases surrounding their ability to identify and prevent possible frauds. As a result, various skills must be utilized in the process that will help to improve the effectiveness of actuaries. These include: good communication, the ability to work well with others, determination, the ability to simplify information and investigative intuitiveness. The combination of these factors is allowing forensic accounts to identify and detect possible fraud. When this happens, the negative impact of these activities can be limited. (Davis, 2011)
Good communication is an important skill because it requires talking with different parties during the process of conducting any kind of investigation. This means collaborating on various ideas and identifying potential red flags.…… [Read More]
Forensic Sciences in the USA and the United Kingdom
Over the last two decades, the forensic science has assisted in producing valuable evidence that has contributed to a successful conviction and prosecution of criminals and exoneration of innocent citizens. Typically, an advanced in forensic science and DNA technology have been a great assistance for law enforcement agency for an identification and prosecution of criminals. In the United States and the UK, many cases that have been formally unsolved have now been solved based on the great assistance of the forensic science investigators. (National esearch Council, 2009). Forensics or forensic science is a field of investigation drawing different scientific disciplines in law, criminal and civil services. This practice requires an application of scientific knowledge, quantitative, qualitative and empirical skills to collect and analyze data that will assist in presenting evidence in a tribunal or court of law. However, the method the…… [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]
In 2002 the crime lab in the state of Mississippi found that the semen in the victim's body belonged to two different men and neither of them was Kennedy rewer. alko concludes by stating: "Forensic scandals have been troublingly common of late, with phony experts, fake results, and incompetent testing recently uncovered in Virginia, Maryland, Kansas, Illinois, and Texas, to name just a few. Courts need to take a more active role in weeding out the Michael Wests of the world before they ever take the witness stand. ut professional organizations also need to be more vigilant about policing their own. Dr. West's peers should more vocally have questioned his methods long before he was permitted to testify more than 70 times in courts across the country. One would think they'd step up their standards to protect the integrity and reputation of their profession. ut these continuing scandals suggest another,…… [Read More]

Opportunities abound in the forensics industry today, and the experts suggest that this trend is going to continue to increase in the future. 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]
obstacles to prompt and efficient forensic investigation in major crime scenes. The presence of too many unnecessary personnel in the crime area and poor communication or reporting of the details are these obstacles. The applicable FI rules and an analysis of each issue follow. A conclusion is also provided for each issue.
Too Many Unnecessary Personnel at the Crime Scene
The presence of too many extraneous personnel is considered the biggest hindrance to effective and prompt crime investigation (Schiro, 1999). What makes it worse is that most of these unnecessary people are police officers themselves (Schiro).
The policy mandates the initial responding officer or officers to identify all personnel or persons at the crime scene and to oversee their movements (FI, 2000). Then the officer or investigator in-charge shall evaluate the scene in order to come up with a list of specialized resources needed in the investigation (FI).

I believe I possess a number of personality traits that are relevant to my career goals of becoming a lead forensics psychologist and earning a PhD in clinical psychology. Foremost among these is the fact that I am hard-working in both the intellectual and physical sense of the term. As a result of my solid work ethic, I am goal oriented and extremely driven to succeed in my aforementioned aims. I am also honorable, and have the best of intentions to better the quality of my life for my immediate family, which includes my husband and children.
This program at Walden is an excellent match for me because it is compatible with the timeline that I would like to accomplish my goals in. Furthermore, I am convinced that this institution can offer me an education that will suitably prepare me for the future career and educational…… [Read More]
However, as criminals become more aware of undercover tactics, the covert officer is required to provide more and more proof that he is indeed a criminal- which leads to the officer committing acts that compromise his or her integrity for the sake of maintaining cover. y understanding the often conflicting nature of these goals, deception and integrity, we can see how an undercover officer can become confused, lost, and susceptible to temptation (i.e. criminal behavior).
y examining both aspects- environmental factors and personality factors- we take into account both sides of a complex relationship. These two groups of factors, when combined together, shed some light on the exact nature of criminal tendencies amongst police officers.
Definition of Terms
Covert: another term for undercover, meaning the use of deception for the purpose of gathering information or intelligence.
Non-covert: police officers that, even in plain clothes, maintain their own true identity instead…… [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]
