Recommended: How will technology help crime investigation

New technologies, such as Faro 3D laser scanning system have been rolled out to aid in crime scene investigation. This portable system is capable of capturing crash sites and crime scenes in 3 dimensions and thus relay evidence within a few minutes instead of the usual time taken. This gives room for investigators to return to the crime scene whenever needed from their mobile gadgets or PCs. Returning to the scene virtually allows the investigators to piece together details they might have missed in the course of the initial investigation by zooming in and out of the crime scene. Such technologies are also capable of providing different views of the crime scene with precision. The Faro 3D laser scanning system uses a camera to capture panoramic …show more content…

A sketch represents a permanent record of the distance and size of a crime scene as well as the evidence contained. A computerized sketch assist is accurately portraying the physical facts of the crime scene and gives relevance to the sequence of events as they unfolded at the crime scene. The sketches are also useful in the witness and suspect interrogation in addition to being admissible in court. Sketches may be presented as video documentations or as photographs and are used in preparing written investigative reports for use later in the process of …show more content…

This also assists detectives in the monitoring of malicious activities that may take place in such a crime scene as it is useful in thwarting false alibis. The access-control devices are usually in the form of smart cards, keypads, key fobs, and biometric sensing equipment, which are used in detecting and measuring voice, gait, fingerprints, and unique physical characteristics. The biometric devices are usually mounted on the controlled areas with transmitted data being stored in a database for investigative purposes. However, the biometric devices may be affected by certain changes, such as retinal changes or pupil dilation thereby being subject to giving some force information about a

    From a trial strategy point of view, you always start with the piece(s) of evidence you believe are most damaging to the client's case and work backwards looking for an exploitable flaw in the search and seizure procedure that would make that or those item(s) inadmissible. The further back in the series of events you can argue a fatal flaw, the more likely that the evidence and any additional materials which flowed from that particular item of evidence will be excluded. This is the practical analysis of all the times we see or hear of law enforcement arguing that there was some technical item which drew their attention and suspicion and justifies their hunch that criminal activity is afoot.

    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...

    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.

  • The Pros And Cons Of DNA Collection And Its Relationship To Solving Crime

    1511 Words  | 4 Pages

    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...

    Law enforcement uses several methods to solve all types of crimes. Having a variety of ways to help solve an investigation gives officials an advantage. If one method fails or isn’t helpful, there are several others they can rely on. For instance, if there are no physical witnesses to a crime, the criminal may have left a fingerprint at the crime scene. An individual’s fingerprint is unique, “no two persons have exactly the same arrangement of ridge patterns” (“Fingerprint ID”). Fingerprints of criminals and of civilians are collected and stored. Also, “People who apply for government jobs, jobs that handle confidential information, banking jobs, teaching jobs, law enforcement jobs, and any job that involves security issues can be fingerprinted” (“The First ID”). Fingerprints are processed within hours and minutes through the Integrated Automated Fingerprint ID System. This system was developed in 1991, and made it easier for different law enforcement agencies to store and share fingerprints.

    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 evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.

  • Collecting the Evidence From a Crime Scene

    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.

    Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice

    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.
