...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...

...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...

...Babylonians also made use of fingerprinting on clay tablets for business transactions and as a means to preserve identification for other official needs. Forensic science continued to evolve, and in 700 B.C., the Chinese began to record thumb prints on clay sculpture and documents despite having no formal classification system was in place. In 250 B.C., an ancient Greek physician, Erasistratus, created the first lie detector test when he noted that his patients' pulse rate appeared to increase when they lied. In 44 B.C., a Roman doctor examined Julius Caesar's body and discovered that of his 23 stab wounds, only one was fatal. The 1100 A.D., crime scene investigation had improved to such a degree that Roman attorney Quintilian proved that blood-covered palm prints were left at a crime scene to frame a blind man for the murder of his mother. Nearly 150 years later, in 1248 AD, the first documentation of medical knowledge aimed at solving crimes was recorded in the book "Hsi Duan Yu" (the Washing Away of Wrong). It detailed the process of distinguishing drowning from strangulation. Over the next 500 years, advancements in crime scene investigation focused on the many aspects of fingerprint detail and chemical elements like poisons. In 1813, Mathieu Bonaventure Orfila, who is considered the father of modern toxicology, published "Traite des Poisons," and in the mid-1800s, investigators at Scotland Yard began to conduct bullet comparisons. Following these advancements, investigators...

...Rebecca Walker Forensic Toxicology CRJ 311 Dawn George 4/22/2013 History Forensic science is defined as the application of science to the law. There are different types of forensic science, and each plays an integral part in the criminal justice system. Forensic biology usually involved DNA testing and its results. Forensic anthropologists examine human remains that have become skeletons in an attempt to determine how long the remains have been in a location and to try to determine a possible cause of death. Forensic toxicology falls into the category of forensic chemistry. Forensic toxicologists study toxins, drugs, poisons, alcohol, and other things found in the blood or tissues of crime victims or perpetrators. Forensic toxicologists study the blood and tissues of living people as well as deceased persons. The rapid advancement of technology in the last century and, in particular, the last three decades, has helped forensic scientists solve many crimes, even those that had been cold for decades. Technology is quickly changing and improving the methods by which crimes can be solved. The first evidence of scientific methods being used to identify people occurred in China in 700BC. Chinese artists used fingerprints to identify pieces of art they had produced. Of course, there was not computerized system to file or categorize these fingerprints. However, this is the first known instance of fingerprints being used for identification purposes. Clearly, things...

...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...

...Forensics History Theresia L. Coates Criminal Justice 1010 Forensics History What does Forensics mean? How old is forensic science? When it was first applied to the law? How has the Forensic science changed the arrest and prosecution success of criminals? The term "forensic" comes from the Latin and means, simply, having to do with the law. How has Forensics evolved from the beginning until today? Let us delve into the history of forensics and its blossoming partnership with the law. Surprisingly, Forensic Science has been around and used in criminal investigations in some manner since before the Roman Empire making it centuries old. It has only been within the last century that law enforcement agencies and the court systems have come to rely so heavily on the use of scientific practices in crime scene investigations.1 The first application of forensic science was by the Roman physician Antistius in the year 44 B.C., whom examined the body of Julius Caesar. He determined even though the dictator was stabbed 23 times, only one wound through his chest caused his actual death. This autopsy is thought to be the first one recorded and the start of using forensic science. Here in the Greek and Roman society extensive knowledge was developed regarding the production, use and symptoms of various poisons, making it possible to identify their use in previously undetected murders. Thanks to these western civilizations advances in the medical field as well as pharmacology were...

...Forensic science, has made great progress over recent years and scientists can gather an incredible amount of information by examining a corpse. It is such a broad field, and there are so many areas of expertise. As forensic scientists of various diciplines work together, they can produce enough information to give the person a background, a location of death, and last but not least a face. Identifying the victim can sometimes not be as simple as looking at their face and matching them to a description given by a worried relative or loved one. Sometimes there are extraneous forces at work, which make identifying the victim a long and laborious task. The main reasons for difficulty in identifying the victim are massive head trauma, submergence in water for long periods of time, decapitation and disfigurement All of these are of course guesome in their own right and the task of identifying a victim can be made much trickier if any of these issues arise. Normally dental work, blood tests and fingerprinting would go some way in making a positive identification of a corpse but there are other things to take into consideration Criminal examinations of the deceased, natural disasters and those caused by malice are sadly becoming an everyday part of life, making this field more and more prominent in today’s society. When we see this area of work in films and programmes the bodies often have teeth, an external or internal deformity, or something that makes the identification progress...

...police has increased fivefold since 1960. Their resources have not kept pace with their workload. To do their job, police frequently have looked to technology for enhancing their effectiveness. The police, with crime laboratories and radio networks, made early use of technology, but most police departments could have been equipped 30 or 40 years ago as well as they are today. The Crime Commission in response to rapidly rising crime rates and urban disorders. The Commission advocated federal government funding for state and local criminal agencies to support their efforts. It called for what soon became the 911 system for fielding emergency calls and recommended that agencies acquire computers to automate their functions. But even with the start-up help of hundreds of millions of dollars in early federal assistance, computerization came slowly. Only in recent years have many agencies found the use of information technology significantly helpful. Examples include fingerprinting databases, computerized crime mapping, and records management systems doing everything from inventorying property and cataloging evidence to calculating solvability factors. Of all criminal justice agencies, the police traditionally have had the closest ties to science and technology,...

...Homicide Homicide Forensic science plays a huge part in our criminal justice system today. But where did it get its start? What procedures are utilized today to help investigators solve our everyday mysteries when it comes to crimes? In addition, what forensic aspects in the video “Welcome to Homicide” were used to finally get a confession of murder? This paper will discuss these topics and elaborate on some of the key evidence that was used to close this particular case. First, let’s begin with where and when forensics is aid to have gotten its start. The basic sciences began to develop in the late 18th century, and many of the early developments in forensic sciences took place during the 19th century (Gaensslen & Larsen, 2013). People long ago did not have technological and scientific advancements that we take for granted in the forensic sciences today. Instead, they mostly relied on forced confessions and testimonies of witnesses. This, naturally, allowed for many criminals to walk free while a lot of innocents were wrongfully convicted. The first known instance of forensics being used was in the year 1248. A Chinese man, called a death investigator, used experimentation to determine that a victim's fatal blow had resulted from the strike of a sickle (Dirkmaat, 2012). What we think of today as forensic science may have been born in China, but truly developed in Europe during the 1700's. German medical experts, Swedish chemists, and Italian surgeons wrote...

...Wrongful Convictions Author: Balko, Radley After carefully reading the article “Wrongful Convictions” by Radley Balko (Reason. Jul2011, Vol. 43 Issue 3, p20-33 14p.) I have learned how our technology has advanced greatly in the last 2 decades as far as DNA testing and Forensic Science is concerned. Though still suggests all possible mistakes and errors made in a wrongful conviction case. This article has also shed light on the ignorance and indolence of our government and all other parties involved in these wrongly convicted cases such as our law enforcement, members of the bar, judges, forensic analysts, and many more. As well as pointing out the trials and tribulations of the wrongly convicted from the first initial interrogation to the conviction and then on to what may or may not lead to their cases being overturned and those accused of being “guilty” proven innocent and being set free. Their main example used in this article pertaining to the wrongfully convicted cases in the United States was a man named Paul House. The first exoneration took place in 1989 thanks to the advancement of DNA testing. Since then 268 convicts have been exonerated and set free. On average most of those had already served 13 years in prison as well as waiting on death row. It has been found that 17 convicts that have already been sentenced to death were wrongfully convicted. Now since the onset of DNA testing in the year 2000 it has added great pressure for those awaiting the death penalty...

...Organic versus Inorganic Jeremy Merritt CRJ 311 Forensics Instructor Janice Bella March 4, 2013 Organic versus Inorganic Growing up as a kid I was forced to watch the television shows my parents enjoyed. During that era murder mysteries were extremely popular. Shows like Jake and the Fatman, Colombo, Matlock, and Murder She Wrote just to name a few. None of those shows relied heavily on science per say, moreover, those shows were written with the most insignificant clue becoming the one piece of evidence that is the key to the whole case. Just as dated as those television shows, so is the investigative practice. Present day, almost all investigative crimes involve the collection of forensic evidence that is broken down into two categories: organic versus inorganic evidence. This paper will detail the differences between organic and inorganic evidence, explain the strengths and weaknesses of each, and breakdown the significance of either organic or inorganic evidence as it travels through the justice system from the crime scene to prosecution. The way evidence collected can be broken down into two categories; organic and inorganic. According to Saferstein (2011), “Organic substances contain carbon, commonly in combination with hydrogen, oxygen, nitrogen, chlorine, phosphorus, or other elements. Inorganic substances encompass all other known chemicals substances. Each of these two broad groups has distinctive and characteristics properties (p. 123, Para 3). In laymen’s...

...Internship | Heating up: Cold Cases | Meredythe Leonard | | Heating Up: Cold Cases Countless developments in police science have occurred in the past decade or so. Many of these improvements can be seen as small, but imagine the challenges faced by crime scene investigators 50 or more years ago. The law enforcement agencies of the past did not have routine access to the amount information that officials today can gather and analyze from a crime scene. Current day crime scene investigation can range from the downright tedious to the technologically astounding, but they have all greatly impacted how evidence is collected, documented, and analyzed. There are around one hundred unsolved homicides in New Hampshire alone, dating back to the early 1960’s. (Department of Justice, 2015). Evidence from those crimes could quite possibly be the golden ticket in solving the wrongdoing, but with outdated techniques and capabilities, the answer will remain a mystery. If the state makes older evidence testing a priority, cold cases could finally find the justice deserved with the help of current day technology. Throughout the rest of this discussion, the call for new evidence testing in cold cases is examined while highlighting the need and importance for skilled investigators. Determination and patience, in the advancing field of forensic testing, have unlocked numerous cases not only in New Hampshire, but also across the country. One of the most under-appreciated, yet...

Technology is ever changing and it something that we have all witnessed advance over the course of time, whether that is the progression of a tape recorder, to a CD, a CD to a Mp3, and Mp3 to iPods and iPhones. The only difference is that with criminal justice technology takes them much further than to just being able to listen to music but rather to get ahead of crime and to get a grasp on the criminals who are committing the acts. Technology is insightful in every aspect of the criminal justice system, from the examination to the trial of crimes. The advancement of technology is already in its most profound stage of conformity. It is allowing us to be visually able to see individuals from space via satellite and target their intellect by viewing what it is they are arranging criminally and for us to use that information to our advantage. Other directions of crime fighting and its role in social policy implications suggest that we are also setting up to not only visually be ahead of the game and criminals in the future but also that we are asking it possible for us to listen more openly to conversations that are being exchanged between criminals. This alone is substantial...
