Abstract
At home, I always watch my favourite TV show which is Crime Scene Investigation (CSI) that is available in AXN channel. I always wonder how the detectives in this show able to identify the culprit behind any murder cases in short period of time. They are very detail in gaining information that they consider any small things that might related to the crime. All evidence at the crime scene is brought back to their labs to further with deep analysis. In crime scene investigation, time really plays a vital role in order to identify the suspects that commit the wrongdoings. Therefore, it is really a need to do an identification

They need to collect any left-behinds that were left by criminals like finger-print, saliva, semen and not to forget, shoe or foot print left by criminals. Although these things are considered frivolous by people, collecting these items can help to lessen the range of people who commit the crime. When processing a crime scene, many variables are usually not known about the suspect. There may be few witnesses and the criminal seldom leaves behind specific identifying information. Information about the perpetrator’s identity is therefore deduced from the evidence left at the scene. A person’s height is one identifying characteristic that is often …show more content…

...me scene, by recreating the scene using the blood direction a bloodstain patterns. Bloodstain pattern analysis use biology, chemistry, math, and physics to solve a crime. In doing research on this topic there is a lot of detail to go into this topic, so in suggestion this paper need to explain the other different investigators that process any crime scene.
I was sitting in the old rickety chair that looked as if it had been there for five years. The smell of gunpowder hung in the morning air as I leaned over the rifle rest. My finger wrapped around the trigger as my eye focused through the scope of my grandfather’s Springfield ’03. I took a deep breath and let half out. My finger tightened on the trigger as I awaited the recoil and crack of the gunpowder igniting. Finally, when my finger’s pull was enough to move the trigger, the gun went off. Moments like this are why I love shooting guns.
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.
The crime scene was then examined and a list of possible pieces of evidence were recorded down. Including a sketch of the crime scene, Anna Garcia’s house, with the locations of all of the pieces of evidence. All of these items listed help develop a theory about Anna’s death. This theory then helped establish a list of possible suspects. The person of interest list included a number of four individuals and each one had a relation with Anna. The list included (1) Alex Garcia- Anna’s ex-husband. They had an unpleasant divorce the year before and in a result Alex quickly remarried a much younger woman, while Anna remained single. Alex and his newlywed wife are expecting to have a baby soon. Although, Alex may be suffering from a few financial
The procedures depicted of the criminal justice system on television are complex, inaccurate, and implausible portrayals of what actually occurs. These shows do not show the planning, timing, and effort that is put into the maintenance of a crime scene. Investigators show up, take some photographs, and continue to the lab for results in a matter of minutes (Forensic Science Degree). Television leaves out the uneventful procedures that are essential in a real crime scene. They also neglect to show how much time is spent on each case, which can take months or even years to finish. There are many techniques and procedures which seem to be forgotten or simplified in the shows. Crime scenes require a variety of people, including the skills of photographers, sketch artists, evidence recorders, and other team members. Intricate notes and sketches of the crime scene give all of the details requ...
Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la...
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 is the employment of science to solve crimes. Forensic scientists use evidence from the crime scene to track the criminal down or determine the guilt or innocence of a suspect on trial. Some evidence examples that forensic scientists use for their job include fingerprints, footprints, teeth marks, blood, semen, hair fibers, bullets, broken glass, knives, and guns. Other useful pieces of evidence criminals are less likely to think about are descriptions, provided by the coroner, of incisions and bruises on the victim’s body. These descriptions can provide clues to the scientists on what kind of weapon was used for the crime. Before anyone can begin doing all this, however, they must receive an education.
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.
Crime scene investigators, also known as CSIs, have played an essential role in protecting citizens, by proving who is guilty, and who is innocent. CSIs use a large amount of Science and Math skills to solve crimes, resulting in a decent income. They are specialized in forensic science in order to examine crime scenes and recover important evidence (Career Cruising).
Some cases cannot be solved without this evidence. “Physical evidence refers to any item that comes from a nonliving origin, such as fingerprints, tire marks, footprints, fibers, paint, and building materials” (“PE”). There is also another group called biological evidence. Biological evidence branches from a living thing, including bloodstains and DNA. Forensic scientists place their evidence into categories including these. “Forensic science is the use of scientific principles and methods to analyze material connected with a crime” (Funkhouser). When a crime is committed, law enforcement officers tape off the scene as quickly as possible (Funkhouser). They then search the area for evidence (Funkhouser). Forensic scientists rarely actually go to the crime scene (Funkhouser). Once all the evidence is gathered from the site, it is then cautiously transported to the crime lab to be analyzed (Funkhouser). Everything about a crime scene is taken very seriously. It is a very tedious process, which takes patience and
The amount of evidence can either help win or lose a case. Every crime scene has evidence available for officers to collect. It is important for them to know what the standard protocol is for collecting evidence and how to properly collect it without contamination.
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.
