...Forensic Science in the 21st Century By: Crystal Lyle AJS/584 - FORENSIC SCIENCE AND PSYCHOLOGICAL PROFILING STEVEN HOENIG 2-29-16 This paper will examine my perception and concept of forensic science in the 21st century. It will also examine the importance of forensic science to policing criminal investigation court process, and the efforts of various levels in security. In addition to analyzing the importance of forensic science, I will give a historical approach. I will discuss the accuracy of the media representation of forensic science and how issues. Lastly, I will discuss the influence the CSI effect have on the judicial process. Forensic Science is the application of science to criminal and civil laws that are enforced by law enforcement agencies in a criminal justice system. Another definition of forensic science is principles and techniques to matters of criminal justice, especially as it relates to the collection, examination, and analysis of physical evidence. In 1929, a Los Angeles police department establish the first American forensic lab. Forensic science has been around over 300 years or more and it continues to improve and emerge today as science and technical knowledge find more improved and accurate techniques. Forensic science has come to be a critical instrument in allowing guilt or demonstrating innocence in the system of criminal justice. In the late 80’s (DNA), society was accepting of (DNA) and forensic science continues to develop and unfold...

...The Relation between Forensic Science and Chemistry Isabelle Génier London Central Secondary School There is a great number of careers that involve chemistry; being a forensic scientist is one of them. What is a forensic scientist you ask? That is a very difficult question to answer. Generally they provide evidence in court to support the prosecution or defence in criminal and civil investigations. The evidence can be provided in the form of a written paper or the scientist might be called to testify during trials or hearings as an expert witness on evidence or laboratory techniques. There are different areas of forensic science such as chemistry (which involves crimes against property), biology (which involves crimes against people), and toxicology (which majorly involves drugs). Being a forensic scientist involves many tasks, they go to crime scenes to investigate and then plan what evidence they need to collect. Afterwards they return to compile, catalogue, and preserve evidence to help solve the case. They then do a sketch of the scene so that they can later reconstruct the crime scene to re-examine, test, and analyze the evidence. Now that the evidence has been assessed, it can be discussed between specialists and a report can be written based on their conclusions. The report is used during trials or hearings; however, the forensic scientist can also be called upon to personally testify as an expert witness. This career, which used to be an unknown field has now...

...The Importance of Criminalistics and Forensics in Criminal Justice System Olympia Hernandez CJ-312 Criminalistics March 20, 2015 Instructor Jorge Valenzuela Criminalistics and forensic science has grown both in scope and importance to the criminal justice system. There is no question that it has become instrumental in complementing and supporting traditional investigations. However, has it become more important than the traditional methods of investigating such as questioning eyewitnesses, interrogating suspects, and determining information from street informants? According to Mary Bernstein, Forensic science has surfaced as a critical tool in assigning guilt or establishing innocence in the criminal justice system. In...

...Digital Forensics: Uganda’s Preparedness Dennis Tusiime Rwatooro 2014-M142-2002 Dept of Computer Science Abstract — The more our lives continue to depend on digital communication networks and media to perform daily activities such as communication, access to information and critical services such as health, financial transactions, entertainment, and public utilities like electricity, the more we get exposed to security risks. These security risks include breach of confidentiality of communication and transactions, violation of personal privacy, crime and fraud, disruption of services, and distribution of inappropriate content, among others. The goal of digital security is to research into and develop mechanisms to address these security risks. In this paper we briefly survey some of the emerging issues in digital security. The literature shows that while some domains in digital security have remained unchanged over a long time, for example cryptography, new areas have emerged including steganography. Keywords – digital forensic techniques, volatitle data extraction, digital image forensics, malware investigations, email security, symmetric key cryptography, asymmetric key cryptography, public key cryptography. Introduction Forensic science is defined as the application of the sciences as it pertains to legal matters or problems (Gialamas, 2000). One of the branches/fields of forensic science, namely criminalistics, is the profession and scientific discipline oriented...

...Forensic Hair Analysis Forensic hair analysis is a method of studying hair found at the scene of a crime, and the scientific study of hair is referred to Trichology. In this paper I will discuss the different techniques that are used to study hair during an investigation and the many different aspects of the hair to consider based on what type of investigation is taking place. Hair analysis can be used to determine the presence of a suspect at the scene or to detect the presence of certain chemical substances in the victim or suspect. With the help of DNA techniques used in forensic hair analysis an absolute match can be determined by examining hair found at the scene of a crime. According to Douglas Deedrick of the FBI’s Trace Evidence Unit, Humans shed an average of 100 hairs daily and are often used in violent crime investigations such as: homicides, assaults, burglaries, and armed robberies. (Deedrick, 2000) The most useful hairs in a crime scene investigation are longer hairs found on the scalp but can be subject to changes due to hair colorings or a simple haircut. In order to prevent this outside exposure samples should be taken from potential suspects as soon as possible after the crime to avoid any possible contamination. According to Deedrick, examining a hair under a microscope can help to determine many things about the source of the hair and even how the hair was lost either through shedding or by force, or from which location on the body the hair originated...

Overall, legal science is intended to utilize experimental standards to clarify obscure parts of a wrongdoing. Through the utilization of uncommon tests and lab gear that permits researchers to recognize decisively different parts of a bit of confirmation in an illegal behavior. On the off chance that you occupied with finding out about how this procedure came to fruition, you have to peruse the recorded data underneath. Here is a brief history of criminological science to demonstrate to you how this practice came to fruition throughout an inordinate length of time. The most punctual legal researchers were doctors who were called upon to give a supposition as to the reason for death in people. Presently the majority of the legal researchers are agents that get pieces of information from the wrongdoing scene and investigate. It utilizes exceedingly created innovation to reveal investigative confirmation in an assortment of fields. Modern forensic science has a broad range of applications. It is utilized as a part of common cases, for example, falsifications, misrepresentation or carelessness. The most widely recognized utilization of criminological science is to research criminal cases...

...Computer Intrusion Forensics Research Paper Nathan Balon Ronald Stovall Thomas Scaria CIS 544 Abstract The need for computer intrusion forensics arises from the alarming increase in the number of computer crimes that are committed annually. After a computer system has been breached and an intrusion has been detected, there is a need for a computer forensics investigation to follow. Computer forensics is used to bring to justice, those responsible for conducting attacks on computer systems throughout the world. Because of this the law must be follow precisely when conducting a forensics investigation. It is not enough to simple know an attacker is responsible for the crime, the forensics investigation must be carried out in a precise manner that will produce evidence that is amicable in a court room. For computer intrusion forensics many methodologies have been designed to be used when conducting an investigation. A computer forensics investigator also needs certain skills to conduct the investigation. Along with this, the computer forensics investigator must be equipped with an array of software tools. With the birth of the Internet and networks, the computer intrusion has never been as significant as it is now. There are different preventive measures available, such as access control and authentication, to attempt to prevent intruders. Intrusion detection systems (IDS) are developed to detect an intrusion as it occurs, and to execute countermeasures when detected...

...As my professor Dr. Randy Oberhoff (Forensic Psychology 6101, 2013) said… “It's not as if there are some founding fathers of Forensic Psychology”. My choice of specialty would be in corrections oriented toward involuntary conferment of the mentally ill; this is because I have worked in this field for the last decade; Dr. Oberhoff centres his field of interest in malingering, deception, recidivism, psychopathy, and rehab for criminals. Theorists that contribute to Dr. Oberhoff area of interests are scholars such as Robert Hare (psychopathy); Rick Rogers (Malingering/deception); and Richard Rogers etc. Our evolving world, multicultrism, poverty, and the highest incarceration rate in the globe- the field forensic psychology is still considered at its early stages. (Bartol and Bartol, 2012) My two personal favourite theorists are Dr. Roger Hare, and Dr. Lorna Rhodes. There are many reasons as to why I chose these two theorists as my favorite for their efforts and contribute in to the field forensic psychology, and correctional services. It was noted by Dr. Gibbons and Dr. Katzenbach (2011)… “What happens inside jails and prisons does not stay inside jails and prisons” (Gibbons and Katzenbach, 2011, p.36). Being surrounded by negativity, fear, anxiety, rumors, hostility, and threat of physical violence have a profound effect on both the staff and offenders in a correctional facility. Dr. Gibbons and Dr. Katzenbach(2011) further state “when people lived and worked in facilities...

...Health Psychology paper Dianna Norris HCA 250 July 19, 2013 Axia College Of University Phoenix Health Psychology Paper Forensic psychology has always been a fascination for me. Forensic psychology is psychological for the criminal justice system. The fascination for me was how the forensic psychologist is able to detect criminal tendencies. The psychological approach is the way the evidence could lead to certain criminal behavior. [ (psychology school guide, 2012) ]For criminal psychologists they have to look at all angles of a way a person commits a crime. The FBI has a behavior science unit and they help with the understanding of criminals and terrorists [ (Portland State University Careers in Criminology and Criminal Justice, 2012) ]. This unit has three other counterparts and they all play a very important part of the FBI, they are the crime analysts, criminologists and clinical psychologists. This is an example of how psychology and criminal justice can overlap. There are many different types of agrees and certifications as well as many paths that can be taken in forensic psychology(psychology school guide, 2012) [ (psychology school guide, 2012) ] . Example: Forensic psychology requires either a Bachelors or Masters Degree. I have thought of this degree ever since I was eleven years old. Family situations quashed me going back to school at that time. At the time I was thinking about this career choice on-line classes were not offered. I would have applied...

...Event-Based Digital Forensic Investigation Framework∗ Brian D. Carrier carrier@cerias.purdue.edu Eugene H. Spafford spaf@cerias.purdue.edu Center for Education and Research in Information Assurance and Security - CERIAS Purdue University West Lafayette, IN 47907 USA Abstract In this paper, we present a framework for digital forensics that includes an investigation process model based on physical crime scene procedures. In this model, each digital device is considered a digital crime scene, which is included in the physical crime scene where it is located. The investigation includes the preservation of the system, the search for digital evidence, and the reconstruction of digital events. The focus of the investigation is on the reconstruction of events using evidence so that hypotheses can be developed and tested. This paper also includes definitions and descriptions of the basic and core concepts that the framework uses. 1 Introduction Since the first Digital Forensic Research Workshop (DFRWS) in 2001 [Pal01], the need for a standard framework has been understood, yet there has been little progress on one that is generally accepted. A framework for digital forensics needs to be flexible enough so that it can support future technologies and different types of incidents. Therefore, it needs to be simple and abstract. On the other hand, if it is too simple and abstract then it is difficult to create tool requirements and test procedures for each phase. For this paper, we have examined...

It is a scientific lab using primarily forensic sciences for the purpose of examining evidence from criminal cases. It provides answers to some or all the questions asked such as how the crime was committed, who committed it, and can also determine whether a crime has been committed or not. The crime laboratory seek answers for the questions mentioned above through scientific analysis of physical material collected primarily from the scene of a crime, suspect or the person affected. It provides an even more integrated approach to the analysis of exhibits and the presentation of expert evidence. Generally the aim of the crime laboratory is to effectively prevent and combat crime. 2. History and background of crime laboratory The Forensic Science Laboratory of the South African Police...

...oday, the word "forensics" has become synonymous with crime and crime scene investigation. Immediately conjuring images of crime labs, ultra violet lights and high-tech computers, popular crimes shows like CSI have brought increased attention to the field of forensic science. They've also generated newfound interest in forensics careers. The term "forensic" comes from the Latin and means, simply, having to do with the law. Hence, any discipline that has any ties to the legal system is, in fact, forensic. This is why so many job titles within criminology, such as forensic psychologist, are preceded by the term. With regard to forensic science, the term is now commonly understood to refer to the application of scientific principles to questions...

...techniques in forensics increased the succession rate of convicting criminals from the period of 1890-1950? Introduction The birth of forensic science within the use of the police force revolutionised how crime investigations were conducted, via the work of the forensic scientists, or also known as ‘forensic officers’. This work would consist of collecting evidence from a crime scene such as looking for fingerprints on either a suspected murder weapon used by the murder or on a touchable surface which is in the crime scene where the suspect laid their hand on. Furthermore this collectivisation of evidence from the crime scene could mean collecting; foreign fibres (unusual fibres that seem to look like that they do not belong their i.e. due to their different colour, type of fabric or thickness of the fibre.); retrieving bullets and firearms form the crime scene and any possible DNA samples that can be collected in the crime scene such as blood spatter on the walls of a room, where in this case the crime was committed. This evidence would then be sent to be analysed by more forensic scientists in different subdivisions to help led a path to a final suspect, thus leading the police to a quick and successful conviction of a criminal and bring justice to their crimes. Overall this revolution of the police force saw the birth of a new era of fighting crime throughout the whole of the country, as well as throughout the rest of the world. How the evolution of different forensic techniques...
