Radiography plays an integral role in today’s forensic society. “Forensic investigations can help identify victims of a mass casualty event, lead to development of improved technology to prevent future deaths or serve as the difference between acquittal and conviction in a court of law.” Forensic radiography, in short, is the use of radiographic techniques accompanying legal usage of such images. Since its discovery in 1895, forensic radiography has advanced into other scientific regions, such as x-ray fluorescence spectrometry (XRF), skeletal scintigraphy (nuclear bone scan), virtopsy (virtual autopsy), multidetector computed tomography (MDCT), and neuroimaging, thus attributing to a large number of ante and post-mortem cases. Forensic radiography plays a pivotal role in archeology, paleontology, art forgery, and drug smuggling (body packers). Proper training and impeccable knowledge is imperative for a successful radiograph to be admissible as evidence in a civil or criminal court proceeding.

Therefore, the criminal justice system relies on other nonscientific means that are not accepted or clear. Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,
Forensic psychology is a continually adapting sphere. It is hard to have one solid definition for the field, as there are so many aspects that interlock. Within each attribute of the forensic psychology has roles and responsibilities to sustain. The rapid growth and emerging importance of this field volumes of information will be developed in the next decade.
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
The capture and conviction of Charles Manson took over one and a half years to complete. Within this time period many law enforcement officers and forensics professionals put in countless numbers of hours collecting, preserving and testing the physical evidence they found. In addition, the forensics practices used in this case as well as the police investigation techniques serve as a valuable lesson for those in these fields today. In this paper we will look at some of the crimes that were committed by the Manson Family, the mishandled investigation that followed and the forensic techniques used to aid (and sometimes hinder the efforts) in obtaining convictions against those involved.
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.

As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the

Crime today seems as if it keeps getting worse and worse, but without forensic science would we have been able to figure out some of the main details in some cases? Forensic science is any science used to help solve a case/mystery, which is very vital when it comes to criminal investigation research. While researching my project I discovered all the many tasks and difficulties that come with forensics.
