There are many aspects and procedures in crime scene investigation that are very essential in each case that is presented. Evidence collection, preservation, documentation and the role Digital Image Capture and Processing are important keys in any investigation. There are protocols that must be followed to protect the integrity of the evidence that is collected. In many instances, cases are lost due to contamination and improperly collecting evidence. To ensure that these steps are taken when collecting evidence, photographs must be taken and documented. These steps are known as Standard Operating Procedures (SOP). SOP is step-by-step instruction that each agency has to help ensure that the collection process is done correctly. Evidence that is collected can be known as physical evidence or biological evidence. Physical evidence comes from a non living origin found at a crime scene that connects to the crime. Biological evidence originates from a living being. Some examples of physical evidence are, fingerprints, hair and fibers, tool-marks, gunshot …show more content…

A chain of custody must be kept at all times. Chain of custody is a legal context that refer to the chronological documentation that shows the seizure, custody, control, transfer, analysis and disposition of all evidence. This is one of many forms of documentation that is used when collecting evidence.
When reporting to a crime seen it is imperative that there is no eating, drinking or smoking taking place. To prevent this from occurring a command post should be designated. To document the times of everyone who enters and exits the crime scene, a Crime Scene Log must be created. Photograph, videos and sketches should be taken of the crime scene to demonstrate and give a visual of the crime scene. However, all evidence is not collected the same. There are different procedures that are taken when collecting different forms of

    Evidence analysis and ranging is the most crucial stage of investigation. The success of the case exposure lies in the gradual evidence research and collecting prior to the laboratory analysis. The CSI systematically makes his way through the crime scene collects all potential evidence, tagging, logging and packaging so it remains intact on its way to the lab. Depending on the task breakdown of the CSI unit he may or may not analyze the evidence in the lab.

    Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne particles, insulation, textile fibers, soot, soils and mineral grains, and explosive residues. Although these are the most common found elements, they are not the only ones. The Trace Evidence Unit is known to examine the largest variety of evidence types and used the biggest range of analytical methods of any unit. materials are compared with standards or knowns samples to determine whether or not they share any common characteristics. In this paper I will discuss the different kinds of trace evidence and how crime scene investigaros use it to solve cases and convict criminal.

  • Forensics in the Criminal Justice System

    334 Words  | 1 Pages

    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

    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.

    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.

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.
