The Importance Of The Three Sources Of Information In Criminal Investigation

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

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

What is crime scene investigation? Crime scene investigation is the use of physical evidence at the scene of the crime and the use of of the deductive and inductive reasoning to gain knowledge of the events and of the surrounding crime. Crime scene investigating is a big combination of Science, logic and law.

In an investigation, an investigator must find ways to recreate an event that had taken place. In order to do so an investigator must talk to witnesses and victims of the crime. Witnesses could include those who either heard or saw something. Many witnesses may not come forward so an investigator may need to ask people who live around the area or people who work around the area where the event took place. An event can also be recreated from the evidence that was gathered from the scene of the crime. With both the statements from the witnesses and the victims along with the evidence from the scene, the investigator must put all of the pieces together and recreate the event that had taken place (Adkisson, 2011).

Criminal investigations are important in a case, whether it be criminal or civil matters. This learner believes that criminal investigations are important, because they allow for individuals to either be proven guilty or not guilty in a case. It also allows for the prosecution and the police to find out who is guilty in a case. According to Osterburg and Ward (2014), Criminal investigations determine if a crime has been committed and determine the jurisdiction of the crime (p. 5). Criminal investigations are important, because they also give victims closure and allow for

Behind every court case there’s a train of forensic science evidence and research. Forensic science is the application of scientific principles of criminal justice. In many court cases a forensic scientists is the one on the scene collecting finger prints, photos, blood samples and other evidence. Unfortunately one of the controversial issues in the forensic world is the evidence and its lack of verification of its reliability. In the field of forensics there are issues in finding proof in generating conclusion, fundamental knowledge to solve problems, and the whole false memory defense in the court. These issues can be solved in many ways like extensive research, preparation and training. These issues

Discuss the three primary sources of information for criminal investigators and provide detailed practical examples of each source listed.

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

After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists

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;

The investigators must identify the significance of every aspect of evidence found in the scene, i.e. they have

The purpose of crime scene reconstruction is to help determine what actually occurred or eliminating actions, events, or suspects through a methodical analysis of identification and examination of physical evidence. By recognizing and identifying the location, impressions, patterns and positions of physical evidence, as well as the scene presentation, an examiner or investigator can apply scientific methods, logic and past experiences to develop a theory in conjunction with information collected from a victim and witnesses (University of Split, n.d.).

Since most investigations start with very limited information, care and common sense are necessary to minimize the chances of destroying evidence. A plan of operation is developed and initiated from an initial walk through of the scene. The plan is to decide what evidence may be present, what evidence may be fragile and need to be collected as soon as possible. What resources, equipment, and assistance are necessary for the processing? Consideration of hazards or safety conditions may need to be addressed.

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.

In the second part of the following essay I will be nominating one source of evidence that is present at the scene of a scenario. I will be discussing in my own words how Police should collate, handle and analyse the piece of evidence in a Criminal Investigation. In doing this I will be using relevant crime scene powers, NSWPF operational guidance and making reference to the Horswell (2004) reading.
