Processing A Crime Scene Investigation Process

Describe three ways that a crime scene can be recorded. What is a benefit of each?

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

Every crime scene has evidence and there is an extended process that must be followed in order to properly mark and preserve any evidence. Once an initial search of a crime scene has been done and all photographs or sketches have been completed it is then that investigators should begin collecting evidence. Each police agency has specific policies and procedures that should be followed during the process of collecting evidence.

Since the time that the scientific science dramatization "CSI: Crime Scene Investigation" turned into a tremendous hit and generated its fans, reporters have been worried about what they instituted the "CSI Effect." The hypothesis behind the effect is that fans of the well-known show disguise misguided judgments about the law that they bring with them into the court as jurors. In this way, the trepidation is that the TV show is at last influencing the results of trials - and not in a great manner. Criminal justice researchers have started to study the inquiry of whether nationals who are called to serve on juries bring unreasonable desires and convictions to the court as a consequence of TV projects. The impact that these projects may have on the jurors, their desires, and their choices is known as the CSI effect.

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.

Crime scenes tell a story, and help tell the tale of the victim and suspect, and how their actions led them to this scenario. Crime scenes can tell a profiler what type of killer they are looking for, either a disorganized killer, or an organized killer. There are certain constants held by both of these factions, and determining which is which is the first step to this strategy. Starting with a disorganized killer, as the name explains, the crime scene tends to be disorganized. The murder weapon will be on site, and it will most likely be a weapon of opportunity, that the killer found on the scene when he arrived. The body will be present, with little to no effort to conceal it. The murder will look like it happened in the spur of the moment, with little to no real planning. There will be signs or sexual assault or general aggression on the body, and this would most likely happen post-mortem, or after the murder. Finally, the victim may be a friend, family member, or acquaintance of the killer. Organized killers tend to leave a crime scene that looks, as the name also entails, organized. The murder will look well-planned, with evidence that effort was taken into place from inception to end. The body will be hidden away from sight, in an attempt to conceal the crime. The suspect might use rope, chains, or

The procedure should accomplish that each type of physical evidence, whether an intact object, pieces of an object, blood, glass, liquids, or gasses, must be collected, marked or tagged, packaged, transported, and stored properly to be later admitted in to evidence in court. The maintaining proper chain of custody is particularly important when the object is one that is not unique or when questions could be raised about changes in the condition of the object, unique or not. Upon arrival at a crime scene, the officer should first quickly determine if anyone is injured or needs medical treatment and, if so, summon the health professionals. Then the officer should survey the crime scene, quickly determine whom to interview, and move nonessential individuals out of the area. The crime scene area should be cordoned off or otherwise closed to nonessential individuals.

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 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;

evidences can tell what sex, age, and race of the suspect. If the scene was not

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.

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.

Forensic science involves the use of science to solve criminal and civil crimes but mostly lies on the side of criminal investigations. It makes it possible to identify the criminals based on the DNA traces they leave behind. It involves analyses of blood, DNA and other evidences and later on uses the findings as evidence in the court of law. It helps in solving the various crimes in the world and this has been the greatest contributor to the growth of the sector. Cases that were previously considered impossible due to lack of evidenced tracing to the victim can now be solved using forensic science evidences. The essay aims at analyzing the different aspects of forensic science that are used in the process of solving criminal activities. It will also look at the different cases that forensic science was used to solve crimes in a court of law.

Today, more than ever, the quality of evidence in criminal cases is scrutinized because of contamination. Contamination is the introduction of something that physically corrupts a substance at a crime scene that was not previously there; it comes in many forms and most often times comes from the humans who investigate a crime scene. It is imperative that prevention of cross-contamination is implemented when gathering evidence. Several of the more sensitive forensic techniques such as trace analysis, bloodspatter interpretation, and DNA comparison are not being used to their fullest potential. Items of physical crime scene evidence are not always visible to the naked eye and may be easily overlooked so deliberate and methodical approach to collection and preservation of evidence is essential. Prosecutors have lost cases due to crime scene contamination; this could be prevented by simple and productive behaviors. The U.S. Supreme Court, in a leading case on physical evidence, stated:

A crime scene is not necessarily the location of a crime, it can be where the planning took place, where the body is found and where the evidence is found. The crime scene can be as small as a bite mark or as large as a geographical location. There are two types of crime scene; primary and secondary. The
