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.
When arriving to the scene you would want to approach slowly. This is for safety reasons as simple as the suspect might still be in the area and it can cause you to be in great danger. You would also want to ask yourself “what crime was committed here?” and a couple of similar questions in that aspect. However, when you do

It definitely have more aspects and complications associated with it. It may seem easy and fun to deal with while watching it on TV, however, it comes with more material. The relationship between CSI and detectives and prosecutors is very important to the crime-solving. If CSI can point out stuff at the crime scene while the detective is working at the office, this will help tremendously. This is about the only thing that is closely related to the real world CSI and the lovely TV show.
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 Throughout this paper I have shown you how to successfully conduct a crime scene investigation. After reading this paper thoroughly you should know to secure a crime scene, collect the evidence the proper way and how to take the crime scenes.
...me scene, by recreating the scene using the blood direction a bloodstain patterns. Bloodstain pattern analysis use biology, chemistry, math, and physics to solve a crime. In doing research on this topic there is a lot of detail to go into this topic, so in suggestion this paper need to explain the other different investigators that process any crime scene.
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.

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.
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.
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
Make sure the crime scene is safe and secure. Once the crime scene is secured, that will be the time to start questioning the victims, witnesses and or the suspects. This would also be the time for some officers to conduct neighborhood canvassing (Hess, K.M. & Orthmann, C.H., 2013). I believe this strategy is important to a follow-up investigation because the witness might hold back information, because they might feel that the information they have is not useful.
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.
Criminal investigation may be a terribly troublesome and dangerous operation of police work. Once a criminal offense happens, a police officer goes to the scene of the crime, gathers information, and searches for for the potential suspects. If in case, there are witnesses to the crime; criminal investigation becomes easier because the suspect is know. Downside arises once the cops don't have any witnesses to the crime and there's no physical proof found within the cri...
Since the old times primary investigations do not typically yield enough information to prosecute a criminal case. The information yielded in criminal investigations may be used to prosecute a criminal case or can even assist in a federal case. Even though primary investigations can identify a lot of evidence and information, a secondary investigation will usually identify further details and allows for a second look at everything pertaining to the investigation. This paper is to explain criminal investigations and the necessary tools and skills needed to conduct and thorough investigation.
