The relationship between photography and criminality is known as the Forensic photography which involves documenting both suspected and convicted criminals, and also the victims, crime scenes, and other evidence needed to make a conviction. Even though photography was known as the most accurate way of documenting, it did not become accepted as a forensic means of identification until the 19th century. It resulted from the development of criminal justice systems and the power of photographic realism. During the 19th centaury, these two developments were significant to both forensic photography and police work in general.
First, government bureaucracies became more professionalized and therefore collected a lot more information about their people.
Other evidence located within the grave consisted of a generic watch, two cigarette butts, a button, a washer and a shell casing. All of these could be analysed for finger prints and DNA. The cigarette butts would also show a serial number indicating the brand (shown in Figure 3), which can be useful if it is found a victim or offender smokes a particular type of cigarette.
In the Forensic Case #356228, skeletal remains of both human and animal were discovered in a hunting area. The skeletal remains were of potential victims named as either Robert Rutherford or Stephen Morton. Robert Rutherford, potential victim #1, was an African American, 65 years or age, had a pacemaker, carried a Gerber 650 knife, had unknown religious affiliations, and was 5’ft 6”inches tall. Potential victim #2, was Stephen Morton, a Caucasian 40 years of age, had a heart condition, was a hunter in the same area, also had unknown religious affiliations, carried a Gerber 650 knife, and was 5’ ft 7” inches tall.
The photographic logs details who took the photos of the scene, which light was used to take these pictures these pictures will later be used to construct a diagram. Finally, the evidence recovery log which lists what piece of evidence was recovered such as bone fragments, articles of clothing, or bullets from the crime scene (Swanson, et al., 2012) In this series, Dr. Brenan can be seen accompanying FBI agent Seeley Booth to interrogate both witnesses and possible suspects. Further, in the series, Dr. Brenan can be seen in possession of a weapon and join the hunt for the criminal. In reality, the forensic investigator is needed in the scene of the crime in order to collect evidence. This type of portrayal from the media is leading the public to believe that both the agent and the investigator or attorney will engage in the “exciting adventures” when the reality is it is just the way the media portrays these types of scenarios (Surette, 2015). The way the series portrays forensic science differs from the real world even though the author of the series is a forensic anthropologist
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 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
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
Just as insight into the mind of the artist may be gained by examining and comparing the progression of his work, so knowledge of the mind of the serial killer can be ascertained by an examination of his canvas: The murder scene. Forensic profiling is the attempt to do just that. An investigator tries to discern information about the killer based on the information at the crime scene, deducing information about the cause from the effect. This is not an exact science, and has been often likened to an art. It is the goal of this work to provide the reader with a basic understanding of the function and application of forensic psychology, as well as an explication of some of its strengths and weaknesses.
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 ...
Collection of evidence is usually a term designated to refer to the collection of physical evidence, government agencies such as police or environmental protection departments will have their own methods for the collection, storage and conservation of physical evidence and it is the responsibility of forensic personnel to adhere to these set guidelines. General principles which are shared amongst various agencies include, the creation of contemporaneous notes, recording the collection of evidence via photographing, videotaping and/or audiotapes, preserving the crime scene by sealing off the location and only allowing designated personnel to enter, avoiding contamination of the crime scene by investigators through the use of full body covering and also preventing cross-contamination with the scene and any suspects.
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.
“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...
