There are several takeaways from my recent CSI class. One, which is topmost in my mind, is that respecting one another is crucial. Our class was made of different ethnic backgrounds, different religions and different ages. We had different ideas and opinions but were able to feel safe in expressing ourselves without judgment. This was largely in part to the instructor educating us on the importance of being open to others ideas at the onset of class. He also reminded us again on a few occasions. It proved to be very helpful and made for an enjoyable classroom discussion each session. Another takeaway for me was all the details that go into Crime Scene Investigation. Unlike on television, there is a lot of very tedious work that must be accomplished to link a suspect to a crime. For instance determining how large the crime scene is and securing it, photographing everything …show more content…
What may appear to be small crime scene can end up being miles wide. Another challenge is taking photographs. The photographer must start with encompassing as much of the scene as possible and then move in toward particular pieces of evidence and show in pictures how the scene looks up close. More photographs are taken after the numbered or lettered markers are put out by each piece of evidence. Additional photographs are taken after the items have been bagged for transporting to labs. Each of these photographs is so important in a court of law. Each photo tells a part of the story.
Gathering evidence takes time and education. While a weapon may be an obvious piece of evidence, there are other pieces that are not so obvious. The pollen on a victim, the soil, plants, water, bugs and insects at the scene could all play a part in helping the investigator determine what took place. There may be a feather or a particular brand of coffee in a cup. Everything in the scene must be logged because each lead must be followed up
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
Judges make rulings on what evidence may or may not be admitted over the course of a trial and technology impacts the way police collect and process evidence, this is true today as well as during the 1892 trial of Lizzie Borden. The rudimentary practice of evidence collection and processing by police was a critical factor in the acquittal of Lizzie Borden. Fingerprinting had not been introduced into the court system and the absence of an eyewitness left the prosecution with little to work with, this left the prosecution only circumstantial evidence but most if not all of it pointed at the defendant. The Borden home was absent of any signs of forced entry and the traditional signs of a struggle couldn’t be located during the police examination but several gruesome facts indicated Lizzie Borden may have been innocent. Medical evidence as to the method used in the killings pointed toward a “tall man” being the culprit, specifically the nineteen wounds inflicted on Abby Borden were said to have been from a dull edge of an axe.
If handled with care the evidence can be the best assistance to the crime investigator and can be used as a major proof in court. To improve the investigation any detective or expert has to admit the necessity of the non-movable items observation and processing apart from the regular movable evidence collection.
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...
Believe it or not, wounds from a victim are also evidence. The wound can allow the investigators to match up any marks that could have been made from the weapon and therefore allows them to determine at what angle, distance, and how fast the weapon was used. The last type of evidence I will discuss is documents. Everyone has different handwriting and different characteristics that make it unique.
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
This is evidence that can be classified into two broad categories which is demonstrative evidence and substantive evidence, The demonstrative evidence in a trial is the evidence other than a testimony that is presented during the course of a civil or criminal trial the demonstrative evidence includes actual evidence examples include (set of bloody gloves from a murder scene and illustrative evidence photos and charts. In trial cases many attorneys view the presentation of the evidence as demonstrative. A common example of demonstrative evidence is a still photograph, photographs of plaintiffs bruises taken immediately after an accident, these pictures will be able to help jury understand and see what took place at trial even if the trial is months from that date the injuries actually happened on. In this case a photograph, which is to be considered as demonstrative evidence could possibly solve a case and answer lots of questions a jury might have also questions and concerns the jury might have of the victim. Also another example would be aerial photographs of the crime scene of a vehicular accident can show how a particular intersection is laid out and can make more clear an ambiguous description of a bind intersection given by a witness.
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.
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.
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

methods when examining crimes scenes or looking at evidences in labs then many cases would be lost in
Physical evidence is additionally important in every criminal investigation because too often witness accounts are sometimes biased or unreliable. Physical evidence such as trace evidence, DNA, and fingerprints may objectively attach one or more persons to a victim or suspect to a crime. Favorably, physical evidence can also demonstrate inestimable for exonerating an innocent suspect. Laboratory members and criminal investigators should perform together to resolve the biggest portion of evidence to institute the right suspect for a strong prosecution. Willingly, investigation officers should aggressively contact laboratory personnel when questions arise about the cases because DNA evidence is sensitive.
Crime scene investigation is the use of physical evidence at the scene of the crime committed, also reasonable and unreasonable reasoning to gain knowledge of the events surrounding the crime. Criminal investigators pursues to establish the methods. Motives, and identities of criminal. This paper will go into great depths of how to conduct an investigation and the proper way to obtain the information. After reading this paper you should be able to know step by step how to keep notes, take accurate photos and a variety of other things that will allow you to conduct a successful investigation.
