Crime scenes are searched in order to find and collect evidence and clues. First, the investigator must insure that the scene is secure and protected. Next, the investigator must plan their search and determine the number of personnel and equipment that will be needed. It is important to remember not to begin searching until the scene has been documented through notes, photography, and sketching. The normal procedure in planning a crime scene search is for the lead investigator or search leader to survey the crime scene by doing a walk through and assign subordinate workers to tasks. There are several factors to consider in the planning process. The factors are the location of the crime, the type of crime and evidence sought, where evidence is most likely to
Investigation Techniques of A Homicide The O. J. Simpson double murder trial is perhaps the most publicized case this decade. However, before the police can arrest Simpson and prosecute him, they must investigate. The investigation techniques LAPD used are used all over the world. CRIME SCENE Patrol officers received a disturbance call at Nicole Simpson's residence. They arrived on scene and discovered two bodies. They looked around to see if the suspect is anywhere around then they checked to determine the two
The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination
The purpose of this project is to provide the reader of this paper with a descriptive analysis of an episode of Crime Scene Investigations (C.S.I.). The intent is to show what is provided by the television series of what happens in a crime and what is supposed to happen during a crime scene investigation. The reader should be able to understand during this analysis to what in fact is non-realistic in this television episode and what is reality as determined by what has been researched. This will show what really happens in a crime scene investigations lab.
Like you see in the Crime scene investigation shows like CSI and Bones, there are many things that go into investigating shows a lot of those things happen but it takes much longer than forty or sixty minutes to solve the crime. While crime scene investigating is very serious job, collecting evidence at crime scenes requires education and knowing of what you're doing, requires hard work, and it can be difficult to perform this job.
In a criminal investigation, there is the need to break down two things. Firstly, the investigation itself and secondly the investigator involved. It is of utmost importance that the criminal investigation is done accurately, failure to do so will have negative consequences on the society. Investigation involves the collection of facts, scenarios and situations which are directly or indirectly related with the case. Whereas investigator is the person who should observe, question, analyze and scrutinize the available details. Careful evaluation then helps to achieve the much needed evidence. Criminal investigation is one of the most essential functions of the Law Enforcement agencies, as it is their prime responsibility to maintain a secure environment and
Chain of Custody & Preservation of Evidence Idris Rawls Westwood College It does not matter the reputation you have earned for your high integrity and honesty, you will always be open to allegations of civil or criminal liability. The first type of evidence and usually the most obvious is physical evidence.
The first step in the process is the investigation. Once an offender initially commits a crime and officers are contacted and make an arrest, they have to investigate further into the crime at hand. Evidence is then gathered and follow up investigations attempt to put the pieces on chronological order to show what happened before and during the time of the crime. There are also many efforts to identify some possible suspects to further the next step of the criminal justice process.
By now the crime scene has been labeled a homicide and detectives have been dispatched to the scene. When the detectives arrive the lead officer will then provide a detailed crime scene briefing to the detective in charge of the scene. This briefing will be the only opportunity for the detective to receive the initial aspects of the crime scene prior to subsequent investigation. Since the crime scene and any/all evidence collected are the key factors in making a case, the crime scene must be documented as soon as possible including, appearance and condition of the scene upon arrival, lights on/off, shades up/down, doors, windows open/closed, any unusual smells, ice, liquids, weather conditions, temperature, and any personal items that may have been left behind. Once the lead detective has been briefed and evaluates the scene him/herself, he/she will then need to determine if consent to search and/or obtaining a search warrant is needed. The scene assessment allows the lead detective
How different stages contribute towards a successful outcome The procedures and techniques used in any criminal investigation help the investigators to do their investigation properly. By correctly following the investigative stage, the investigators can improve the quality of their case and investigation and the police will get a better chance to solve any criminal case. In any criminal investigation, five stages are involved. The police and investigators have the duty to follow all this stages, in order to get the best results.
In the documentation stage of an organized approach for processing the crime scene all functions have to correspond and be consistent in depicting the crime scene. The final results of a properly documented crime scene are the ability of others to take the finished work and reconstruction the events that occurred at the scene and make a court room presentation. In the Scene Documentation stage there are three simple steps to properly document the crime scene written notes and reports, photographs, sketching.
In the episode “Gum Drops” of the series CSI: Crime Scene Investigation, one of the featured forensic analysts was a crime scene investigator. The duties of a crime scene investigator are diverse, and include tasks such as securing and processing the crime scene, documenting the crime scene with photography and
The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;
They have to make sure that before they entered the crime scene, nothing in the scene should have been moved. While they are going through a walk-through, they may have to construct theories about what happened in the crime scene based on visual examination. Investigators have to take photographs of the scene and will later on be collected. Taking photographs of the scene will help them solve the crime because there are some points of the investigation that investigators may have overlooked evidence, and that evidence could be found in the photographs. After taking photographs of the scene, they will start to collect clue and evidence that may lead them to their possible suspect(s). What they may find in the crime scene are fingerprints which can be done using colored powder and a brush, other thizngs such as blood, firearms, hair, glass and many more things that can be found in the crime scenes.
The first is the preservation of the crime scene. If the crime scene has not been secured and borders not set up this will result in the contamination or loss of physical evidence, which is crucial in a reconstruction. The second is an investigator is the use of inductive and deductive reasoning, not have any preconceived ideas) by using the facts of the case, in addition to photography, video, crime scene sketches, and other documentation to draw inference (M.U.S.E.
