When the call comes in that a crime has been committed, the police are dispatched to the crime scene. When the police arrive on scene, they need to take control by apprehending any suspects and looking for witnesses/victims. If the scene is not safe, the first responders must secure the area. If anyone is hurt, they should call for medical personnel as soon as possible. The first police officer on scene is usually in charge until a criminal investigator arrives on scene. Depending on the crime committed, the crime scene could be as small as the interior room of a building or as large as the whole neighborhood. The whole crime scene area needs to be secure so that evidence is not tampered with by anyone.
The police officer in charge can start a search for more evidence so that it can be secured by the time investigators arrive on scene. There are five different search methods; the point-to-point movement, ever-widening circle, ever-narrowing circle, zone or sector search, and the strip or grid search (Lushbaugh, and Weston, 2011). Each search is used under different circumstances that all depend on how large the crime scene is and if it has occurred indoors, outdoors, inside of a building, etc.
Once a criminal investigator arrives, the police should have the area secured so the investigators can do their jobs. Investigators will enter the crime scene and will have some equipment to preserve evidence on hand. Evidence won’t be removed until proper procedures are followed so that it is not jeopardized. They will number each piece of evidence and take pictures of it. For example, if there was a drop of blood on the ground, a number would be put next to it and a picture would be taken. The pictures will be up close, ...

...y quickly and can document accurately. Investigators can go over the crime scene and look for any evidence that may have been missed. Overall, crime scenes that are committed inside of a building are a little easier to deal with than an outside crime scene.

Crime fighting is incredibly time consuming and can be immensely complicated. As I mentioned before, shows will often lead the viewer on to think that one person does all the work at a crime scene. In reality, the process goes more along these lines: When a call is made that needs assistance, a uniformed officer will be the first one on scene. He will do his job of securing the area and making sure any other threats have been neutralized. If he needs, he will call for detectives to come and investigate as well as interview any witnesses in the area. Shortly thereafter, crime scene units will show up and help in recovering physical evidence such as prints or traces of DNA. Following all of these different units and people arriving, the scene and evidence needs to be photographed, documented, and chronicled. Every single member of the team will record his or her own take on the scene by filling out paperwork (Fact vs. Fiction). The bottom line here is that television is
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.
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
CSIs must photograph/sketch crime scenes, take measurements, make observations, testify against criminals in court, and collect, pack, label, document, and analyze evidence (Career Cruising). All of these tasks CSIs must complete, require them to handle a variety of tools including: cameras, tripods, flashlights, notepads, utensils to collect physical evidence, measuring tapes, rulers, microscopes, fingerprinting kits, and even guns in some cases (Career Cruising). CSI agents collect to different types of evidence, when they investigate a crime (Byrd). The first type of evidence is testimonial evidence, which is the answers CSIs questioning suspects and witnesses are given (Byrd). Physical evidence, which is the other type of evidence, is any type of three-dimensional evidence collected at a crime scene (Byrd). Although different CSI teams from different areas of the world can consist of multiple branches, including: detectives, technicians, medical examiners, scientists, and lab analysts, they still use forensics, which is science and technology, to investigate crimes (Zullo). There is always crime, but when there are no current cases; CSIs go back to old/previous cases (McFadden).
As you can see there is no perfect crime. The littlest piece of hair or paint or anything left behind can be found. Suspects often miss these tiny peieces of evidence and while they looked over it, it is still lurking at the crim scene. It is guarenteed that a Crime Scene Investigator will find this evidence no matter how small and use it to find, prosecute, and convict a criminal.
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
The police conduct a preliminary investigation then later conduct a secondary or follow up investigation. The primary goal of the preliminary investigation is to secure the crime scene to protect the integrity of the evidence. The follow-up investigation is when they thoroughly collect, preserve and relinquish the evidence to the evidence tech in the lab with a chain of custody form.
Then comes the investigation process. Officers try to sort through the evidence and come up with a solution or a suspect. Next comes the arrest or citation of an individual if the officer believes that there is enough facts and evidence to do so. If an officer does not find enough evidence or a suspect, the case remains open. After the arrest or citation comes the prosecution and pretrial. The prosecutor considers the evidence by the police and makes a decision whether or not to file charges against the accused. If charges are filed, the first court appearance is held. The accused will then appear in court and be informed of their charges and rights. The judge will then decide whether there is enough evidence to hold or release the accused. The judge can decide whether to hold the accused in jail or release them on
We have already established that for the police to be involved, the crime has to be committed. Once the crime is committed, someone has to report about the crime being committed and when the report has been made, the police begin its job and starts investigating that report to determine if a crime have been committed. O...
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.
Imagine pulling into your driveway and seeing your neighbor’s house surrounded by police, flashing lights, and caution tape with bodies covered in white sheet on the lawn. It was a drive by shooting. Next, a van pulls up and a Criminal Investigator steps out and starts assessing the crime scene. She begins taking photos, marking shell casings, packaging evidence, documenting tire treads on the pavement and inspecting and collecting DNA evidence from the bodies. Criminal Investigators are highly trained college graduates that are a vital part of bringing criminals to justice.
First responders play a crucial role in the establishment of a crime scene. Upon arriving at the scene, the first responders have checked for living victims and have rendered aid. It’s important to create a perimeter around the crime scene (this can be altered if additional evidence is found outside the initial crime scene). Only emergency personnel should enter and exit from the central entry point to control contamination, by creating an exit point; it helps avoid any excessive traffic through the crime scene. By secure the scene to ensure that no evidence is misplaced or damaged, or otherwise compromised. Do a cursory check of the crime scene to obtain any transient evidence and secure any weapons found at the scene (in this case it was already at the scene with the suspect). Crime scene analysts and investigators communicate with first responders and are quickly briefed on the situation, and now a more thorough search can be conducted.
Wilfred a retired soldier saw perpetrators during the perpetrators were changing cars and informed to the police. In here I will clarify each potential evidences of the crime and explain of the application of the identified forensic procedure to the facts of the case. One of the perpetrators cuts his hand when trying to drag of the witness in the 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
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.
