Forensic Science Investigating a Crime Scene

Each one of the steps is very important and must be done in the correct order to make sure that all the evidence is collected and processed carefully. The 1st of these steps is a call out. In this step the forensic technician should record the date and time of the call out (Young, 2011). The 2nd step that a forensic techician should take is what is called a briefing. When a forensic techincian arrives at the scene they should record the date and time they arrived at the scene and also the time that the briefing started (Young, 2011). During the briefing it is normally the patrol sergeant or the first responder is the one that does the briefing, who then tells everyone at the briefing all the detials based on what has been found. The crime scene techician sould also record the names and identification numbers of everyone that is present (Young,

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;

As the Homicide Detective, I must approach the scene cautiously, scan the entire area thoroughly using all senses, assess the scene and be aware of people and

Forensic scientist or Crime Scene Investigator uses forensic science to solve cases. (Forensic Science Investigation Unit, 2015). At the incident scene the Crime Scene Investigator would examine the incident area take pictures, look for fingerprints which can also consist of palm prints and sole prints, body fluids (DNA), tools or weapons, shoe or tire marks, fibres from material or clothing and fragments glass or paint. All these items are collected, processed and analyzed before trial. These evidence have solved many cases that were either cold cases or cases that recently

The world is investing heavily in significant resources and incentives relevant to forensic investigations. Forensic investigations is a specialty in which data is analyzed by experienced and trained investigators. It is important to understand and support forensic investigations for many reasons. Firstly, the ability to take presented evidence and deliver facts relevant to the case plays a fundamental role in redefining law enforcement and the solving of crimes, (Kaminetzky, 2001). Forensic investigations strengthen the criminal justice system by ensuring that more justice is achieved as a result of advances in the studies. Thus, these investigations help solve crimes that would have otherwise been considered impossible to understand. Understanding

First you must analyze and manage the scene. This includes examining the victim. You then document the scene, which begins with a walk-through. As an investigator, your walk-through must not disturb any evidence of the scene. The evidence then needs to be recorded before being altered.

The chain of custody is perhaps the most important aspect of evidence procedure. If trace evidence is improperly handled at any point during its journey from collection, to trial, the entire case against the defendant could be in jeopardy. This paper will examine trace evidence, its requirements, and the necessary steps required to prove its validity during trial proceedings.

This stage is extremely crucial in crime scene processing. The main purpose of this stage is to gather and preserve all the reliable evidence, which can help play a key role in attempting to recreate the crime and help identify the offender, in such a way that the evidence is admissible in a court of law. In addition, each type of evidence has a specific value in an investigation. The value of evidence is kept in mind by the investigator when doing a crime scene investigation. Therefore, the collection process will usually start with the collection of the most fragile or most easily lost evidence. Also, special consideration can also be given to any evidence or objects which need to be moved. I found this to be quite interesting since I thought that all evidence held the same weight in an investigation. I learned that an investigator will spend more time collecting fingerprints then fibers left at a crime scene because fingerprints can positively identify who has been at the scene of the crime while fibers cannot. However, it is important to note that it is wise to collect more evidence at a crime scene than not to collect enough evidence, since an investigator usually only has one shot at a crime scene. Then the evidence gathering then will continue along the crime scene trail. Photos will also continue to be taken especially if

This could be done by a team of investigators or first responding officer that have the jurisdiction to go to the scene of the crime and seal it off. Video recording and photographing of the scene. If necessary as the case maybe, they could undertake a firearms and ballistics examination. That would give them the ability to check for traceable evidence like shoe, tire mark impressions, and to examine any fingerprints.

An investigator wants to have a chain of custody of evidence because if the chain of evidence is compromised, the evidence may not be admissible in court because the opposing side can say that the evidence could have been tampered with. Documentation is important because the case may not go to trial for a couple of years. It can help trigger an investigator’s memory while testifying in court.

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

Forensic science has become an invaluable asset throughout many facets of the criminal justice system. One of those areas that continues to draw interest among law enforcement and court officials, rests in the process of preserving and gathering evidence and the utilization of criminal investigating tools to analyze and reconstruct crimes. The technology and advancements in forensic science over the past decade has led to new breakthrough methods for identifying and understanding physical and trace evidence such as DNA, fingerprints, blood, and foreign substances. Crime itself has existed since the beginning of mankind, with continuous increase in yearly criminal acts, murders, and the overcrowding of prisons, forensic science technology has been catapulted as a priority in the battle to ensure justice continues to be the foundation Americas criminal system.

Preserving the homicide crime scene can not be stressed enough, this step is so imperative. The detective must first conduct an intuitive examination. There is always a verdict at the end of each case and if it were to end in failure or the officer was to be embarrassed in court the primary reason may very well be an inadequate examination of the homicide scene or a failure to implement good basic crime scene procedures. There are a number of steps that a homicide detective will go through to properly examine the crime scene.

Forensic science is an application of science to criminal and civil laws. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation to figure out how things led up to a crime, or how a crime had ended. Imagine a world without forensics- without an explanation of how things happened, of why things happened, or what the motivation was for the things that happen. It would be chaotic- the world would be symbolized as a giant question mark. Thankfully, we are able to have excellent technology to give us answers and understandings. Forensic Science is important to our lives because it gives us opportunities to have jobs that fulfill the needs of criminal justice,

There are many differents things involved in the identification and collection evidence. In order to do these things you have to know what things like what physical evidence is, what impressions are, different types of evidence you could find and how to use it and knowing what forensic science is and the different types is important too. Also you need to know the proper labelling technique.
