Forensic Sciences
Working Together to Solve a Crime
"Wherever he steps, wherever he touches, whatever he leaves, even unconsciously, will serve as silent evidence agents us..." ( as cited in Types of Forensic Scientists) . With crimes going on all around there needs to be some way to solve the crimes. There are many different aspects and objects needed to solve an unsolved crime. Data needs to be discovered and evaluated. Among the data is also many types of clues like fingerprints, media, source of death, etc.: Further more, all of these diverse tasks one person can't do it all. This is where the category of forensic sciences come into play. Criminalist forensics, forensic toxicology, forensic pathology, anthropology, and digital and multimedia forensics are the main sciences that are needed to put the puzzle pieces of a case back together.

Immediately upon the criminalists' arrival, they " must be careful not to contaminate the scene by introducing outside substances to it."( Innes, 2005, p.6) the crimes stage is protected by the criminalists wearing sterilized throw away garments and using special tools to pick up the evidence. Thereafter the scene has been sealed off from pedestrians, criminalists will then search the area for anything abnormal lying around and will collect the evidence( Innes, 2005). They then use tools to break down evidence and use their prior predictions to solve the physical evidence they found. This career uses their knowledge of the data to solve details in an
Crime is a common public issue for people living in the inner city, but is not limited to only urban or highly populated cities as it can undoubtedly happen in small community and rural areas as well. In The Real CSI, the documentary exemplified many way in which experts used forensic science as evidence in trial cases to argue and to prove whether a person is innocent or guilty. In this paper, I explained the difference in fingerprinting technology depicted between television shows and in reality, how DNA technology change the way forensics evidence is used in the court proceedings, and how forensic evidence can be misused in the United States adversarial legal system.
One scientist was able to tell what a person had done his or her entire life, be it sitting at a desk twenty-four seven or playing professional tennis. The way forensic anthropology is used in an investigation is when a body is found that is beyond recognition, whether it be burned or decomposed. These scientists will clean the bones after a forensic pathologist has looked at the body to see if there are any noticeable differences in the organs or tissues. Once that is done, they will do a facial reconstruction on the skull. Most of the time, this is done to get a positive identification on the body. Then, they will examine the entire skeletal remains, looking for nicks, broken bones, anything that could help identify how the victim was killed. All of these processes take a lot of time to complete, but once they are done, the rewards are worth
Forensic science has changed dramatically over the years in a number of different ways, both positive and negative; new discoveries have altered the ways in which scientific experiments are carried out; how evidence is collected from a crime scene and overall how a criminal is caught as a result of the findings and conclusions made by forensic scientists. Crime has existed for millions of years; however the way in which a crime is detected hasn’t been around for the same length of time. Forensic science has gone through many changes for the better and has become a lot more accurate and reliable since it was first established. The arrival of modern forensic science made apprehending the criminal a lot faster and a lot simpler. The police records are full of anonymous corpses that have been so badly mutilated that they are unable to be recognised by the human eye. This gives forensic scientists a very difficult job; it requires precise medical expertise in order to identify that person and figure out what happened. The
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.
Every day, hundreds of law enforcement officers go out to investigate crimes, whether it is a robbery, a car accident, a suicide, or even a homicide. But has civilization ever stopped to wonder who those behind – the - scene guys are that put all the pieces of evidence together but do not really receive credit for it or the amount of training that goes into becoming a forensic scientist? How about if the forensic science strategies depicted on TV is actually true. Society can give credit to the thousands of forensic scientists who spend their days deciphering evidence ,which is not as dazzling and fantastic as TV plays it out to be. In fact, most of the things portrayed on TV are actually false. Although the forensic science strategies used in the TV shows seem amazing, they are not representative of the real profession and people should realize there is a huge difference between fiction and the real work done. This research paper debates the technology of forensic science, the training involved, the careers that are associated with the field and also how this topic is presented in film.
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
There are six general areas in forensic. Theres a medical examiner, crime laboratory analyst,crime scene examiner and a forensic engineer. determining which one you want can be hard, but its easier to talk to someone who does that job. They can tell you different things about the job.
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.
Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests ran on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background is important.
Collecting evidence from a crime scene is a crucial aspect of solving crimes. Before evidence can be seized, there must first be a court order approving the search of the crime scene and the seizure of the evidence found at the scene. Standard protocol for officers is for them to always use latex gloves, avoid plastic bags, double wrap small objects, package each object separately, and to collect as much evidence as possible. It is better to have too much evidence than to not have enough. There are countless amounts of evidence that can be found at a crime scene.
Imagine pulling into your driveway and seeing your neighbor’s house surrounded by police, flashing lights, and caution tape with bodies covered in white sheet on the lawn. It was a drive by shooting. Next, a van pulls up and a Criminal Investigator steps out and starts assessing the crime scene. She begins taking photos, marking shell casings, packaging evidence, documenting tire treads on the pavement and inspecting and collecting DNA evidence from the bodies. Criminal Investigators are highly trained college graduates that are a vital part of bringing criminals to justice.
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 Scene Investigation For my assignment, I will be looking into the case of James Bulger, aged 2 years old, who was kidnapped and murdered by John Venables and Robert Thompson on February 12th 1993. Through evidence found at the crime scene and testimonial statements, the police saw that the two boys, ages 11, abducted James from Bootle Strand Shopping Center, Liverpool. They took him on a long, aimless walk where they brutally attacked him and left him for dead. In my assignment I will show how work done by the police, forensic scientists and Investigators helped to convict Jon and Robert.
There are several steps that need to be taken in order to process a crime scene. Some of the steps include: securing the scene, a detailed search, documenting the crime scene, collecting and preserving evidence, and finally releasing the scene. All of the following steps are crucial to avoid any possible contamination or otherwise compromise the scene before it can be released. Few, if any additional opportunities exist when processing a crime scene, so the first time is most pertinent.
“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
