4-1 Analysis Of Sand Sample

I feel that this case was somewhat representative of what was discussed in the textbook. The forensics aspects of this case were generally different from the impression of forensics I received from reading the textbook. Despite this fact, I feel that the investigative techniques of this case were similar to what was discussed in the textbook, as well as what has been discussed during lecture.

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

a Double Murder Case: Using Forensics to Inspire Future Generations of Soil Scientists” by Robert W. Fitzpatrick and Mark D. Raven, ask how can Forensic Soil Science be used to solve investigating cases, within law enforcement, such as a double murder case presented in the article. As described in the article, Forensic Soil Science is the study of soil (surfaces) that use a variety of soil information to resolve legal questions, problems, and hypotheses. How Forensic Soil Science and solving murder cases can relate is clear, Forensic Soil Science takes evidence that involves soil on objects and exams them to see if there’s a match with the soil found on the piece of evidence where the crime was commented. Most of the crimes involve some type of surface or soil, which makes the both relate to one another. The research disciplines that are related to this research are, Criminology, Soil Science, Pedology, and Mineralogy.

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

Its imperative to understand that crime scene investigation and forensic science are both similar fields of study. Both of these careers require a criminal justice degree and solely focus on the aftermath of a crime. The ultimate objective of both is to gather and analyze evidence to solve a crime. Each of these professions playing an integral role in the flow of analysis in the criminal justice system. By working together, an CSI examine the location and gather evidence at the scene and bring the evidence back to a forensic scientist to analyze. They both utilize the scientific and

The expert testimony in the Wayne Williams case was vital in explaining the evidence to the jury (Imwinkelried, 1983). It is reasonable to concede that jurors have no prior knowledge of forensic science. Additionally, jurors will most likely have no prior knowledge of the different variations, color spectrums, moreover the uniqueness of various items presented as evidence in this case. As a prosecutor, it would important to include the testimony of fiber experts with extensive knowledge of the article presented. This expert would be able to articulate to the jury the unique qualities as well as characteristics of the fibers.

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

When scientist were unaware of what happened during a crime, or where it was located, soil can tell all. Soil is everywhere and has different compounds and 'ingredients' that can depict where and what happened. So one came into this case and look at pollen samples taken from Mellory's nasal passages and her clothing and try and link it to locations that the police are wondering about as far as potential scenes for the

During the investigation, two cups were sitting on the table. One cup with Ray’s name and another with Max’s name. After testing the pH levels of the beverages it was revealed that Ray’s cup had a regular pH level and Max’s beverage had a high basic level (Forensic Report). There was no blood at the crime scene so it could have been possible one of the suspects tampered with Max’s drink. Since in Ray's testimony states he “found the body at 2:55” and “called to the others at 3:00” (Suspect Case File) there five minutes of time in his alibi for question of what he was doing. After testing the fingerprints on Ray and Max’s cup it was revealed that Ray’s fingerprints were found on Max’s cup (Forensic Report). After careful consideration of both pieces of evidence it is quite clear Ray did in fact touch Max’s cup. Which could have resulted in the cups having different pH levels. In conclusion, there were strong pieces of evidence which are tied to Ray, which makes him guilty of the murder of Max

A segment of the Forensic Science in the Criminal equity organization that the vast majority acquainted with these days, however, few individuals know how this particular science came to be. Overall, legal science is intended to utilize experimental standards to clarify obscure parts of a wrongdoing. Through the utilization of uncommon tests and lab gear that permits researchers to recognize decisively different parts of a bit of confirmation in an illegal behavior. On the off chance that you occupied with finding out about how this procedure came to fruition, you have to peruse the recorded data underneath. Here is a brief history

The results in this lab showed that suspect 2 was a match for the DNA found at the crime scene. This was determined by DNA fingerprinting. In this lab, the samples of DNA from two suspects and the DNA from the crime scene were cut with two different restriction enzymes and then the DNA was run through gel electrophoresis. The different restriction enzymes cut the DNA in different places, so when the DNA was run through the gel, the gel showed two fragments for each sample based on their size. The fragments shown are known as bands of DNA. These bands of DNA for each suspect were analyzed and compared with the bands of the DNA from the crime scene. The bands of DNA were compared based on the distance they traveled through the gel from the wells.

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;

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.

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:
