One of the biggest legal challenges of crime scene investigations is whether federal or state procedural laws were followed correctly, failure to properly conduct procedural steps in the collection of evidence could result in the evidence being contaminated, altered, or if stored improperly it would result in the lost of evidence (Buckles, 2006, p. 29). Evidence that is not properly documented will not be admissible in court or if the evidence was obtained illegally meaning that the evidence was collected without a warrant when a warrant was needed the evidence will not be admissible in court therefore it is crucial for law enforcement and investigators to be familiar with the laws that govern crime scene investigations (Buckles, 2006, p.
On the afternoon of March 12, 2015 I responded to the call of shots fired and two people injured near the Ferguson, Mo, police headquarters. When I arrived I noticed to officers were laying on the ground, I called for EMT’S and backup. Then we sealed of the perimeter, so we can work to provide proper medical attention to the officer’s. Then we proceeded with the investigation. I then examined the crime scene looking for any evidence or clues I could find.
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 gathering, protection and safeguarding of evidence is a crucial facet of evidence integrity, without accurate adherence to these processes, vital evidence that could possibly have significant influence on a court case could be deemed inadmissible. Therefore identifies the importance in establishing policy and procedure for law enforcement agencies in the identification, collection, and storage of evidence. Objects that constitute fruits, instrumentalities, or evidence of the crime or are contraband may be introduced in evidence and exhibited to the jury if it is proven that such objects offered as evidence relate to the crime charged (Garland, 2015, p. 417). Below is a procedure for handling physical evidence for presentation
Tashanna N Garcia is currently enrolled in the Masters of Criminal Justice, with a concentration in Forensic Science, program at Saint Leo University. Tashanna comes from a military background where she served as an officer in the United States Marine Corps. Her military training was essential to her transition into law enforcement, where she spent the last ten years working for two police departments as a patrol officer and then for the Alabama Department of Public Safety as a Traffic Homicide Investigator for the State Troopers. Tashanna hopes to return to the law enforcement field in an administrative capacity and has a passion for forensic disciplines. Correspondence concerning this paper should be addressed to Tashanna N Garcia,
I have always loved suspenseful whodunit television shows, movies, and books that use forensic science to crack the cases. My favorite television show is The First 48, my favorite movie is The Silence of the Lambs, and my favorite book is The Body Farm. Therefore, I was excited to have the opportunity to take this course and learn even more about the subject of forensics. This essay gives a summary of N. E. Genge’s book, The Forensic Casebook: The Science of Crime Scene Investigation, and includes the things I disliked and liked about the book.
Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with
In this position paper I have chosen Bloodsworth v. State ~ 76 Md.App. 23, 543 A.2d 382 case to discuss on whether or not the forensic evidence that was submitted for this case should have been admissible or not. To understand whether or not the evidence should be admissible or not we first have to know what the case is about.
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. Evidence can be anything from tangible objects such as cartridge cases and firearms to latent fingerprints and DNA. Evidence collection or recovery step in crime scene processing is the methods, techniques, and procedures used in retrieving evidence. Patience and care are very important at the crime scene. The criminalist should take the proper time and care in processing the scene. The work is tedious and time consuming.
Forensic evidence has been shown to be reliable due to many factors of evidence such as DNA, blood, fingerprints, etc.; however, many cases have shown that
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
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:
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.
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
The entire investigation hinges on the first person that arrives on the scene ability to properly identify, isolate and secure the scene. Establishing a restricted perimeter is key so civilians do not damage any evidence. The chain of custody must be established immediately once objects are photographed and sketched the scene is completely. The chain of custody is the written chronological history of who had the evidence when. Tampering of evidence can make or break one’s case. Patience and care are very important at the crime scene. The investigator should take the proper time and care in processing the scene. The work is tedious and time consuming but extremely important in any case. You only have one chance to get it right because once it goes to trial it more than likely over at that point and in the hands of the
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.
