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.
Word choice is perhaps one of the most important aspects of writing in the forensic science discipline. “Fingerprint examiners often argue that because friction ridge formation is induced by the stresses and strains experienced by the foetus in utero, which are random and infinite, it is likely that they subsequently produce a random, infinite variety of friction ridge patterns.” (Page, 2011). In the forensic science discipline, there are keywords that have to be known to have a professional and scientific style of writing the will be acceptable. A forensic scientist cannot write a report about the fingerprints of a subject and say that the has a unique pattern of bumps on their fingers. They have to use keywords such as friction ridge patterns, for their report to
The world of Forensic Scientist is an amazing and fascinating place. There are so many aspects that go into forensic science but in this paper we are only covering bloodstain spatter patterns. Bloodstain spatter patterns are not solely used to solve crimes but I do feel it is one of the most important. Bloodstains never lie.
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.
Durning the case, much of the DNA evidence found on scene traced back to O.J Simpson. On scene there was a glove found that matched the glove found in O.J Simpsons yard. Robitaille states that the glove was huge evidence, “One dark, cashmere-lined Aris Light leather glove, size extra large, was found at the murder scene,
During this trial there were three invalid forensic sciences used in the trial (National Registry). The investigators of this event found soil, hair, and imprints from Barnes truck that were somehow related and similar to Simon (Drahl). Pagliaro, a lady conducting evidence from the scene, had told the jury that she found the fabric from Simon's jeans matched an imprint on Barnes' truck. She also said that there were two hairs in Barnes's truck that were more microscopically similar to the victims than to Barnes (National Registry). This evidence could lead to bad things for Barnes because it looks like Barnes is now more closely related to the
A second item was found, a sock as stated from the article (O.J Simpson civil trial, 10/18/96), they found DNA genetically marking Simpson and ex-wife’s. But as defense spoke, they were not convinced for the fact that t could have been framed, just like the bronco with a blood stain. The bronco was vied by numerous unauthorized people and could have stained the carpet. Studies say, when the vehicle was first seen, there was no blood stains until after. Same goes for the sock, as mentioned (William C. Thompson, professor, Department of Criminology, law &society, university of California, Irvine, California) received Simpsons reference tube. Oddly given information from the tube, there had seem to had been missing a percentage of the blood, tube containing between 7.9 and 8.1 ml, when the LAPD laboratory received, it had been dawned up to eight milliliters (ml), containing 6.1ml inside the tube.
Agent Wilbur’s testimony on the rubber analysis taken from the scene and the tire rubber taken from the rear tire of the defendants’ car being an exact match from the chromatograph machine is specialized knowledge that aid in the trier of facts understanding. Due to Agent Wilbur’s years of experience as an automotive instructor
We did many tests, one of which was where we gathered up multiple footprints including the one found at the crime scene and analyzed and compared them. We also did a fingerprint test to determine
The first were from a dog collar on her body. The suspect had bought a few from the supplier, and the police department also found out that he often hunted in the area where the body was found. The twine used to tie the body bag were used for rabbit netting. The police department tracked down the supplier of the netting to a nearby city, who only produced a batch of it. The same netting was also found in the suspect’s house. The cable ties used to tie Tiernan’s hands together were tracked back to Royal Mail, a patent company of Parcel Force, who Taylor worked for. Finally, there were also pink carpet fibers found on Tiernan’s body, which was connected to Taylor’s home after the last three fibers were also tied back to his house. Hair and blood evidence were also used in the case, but they did not play as central of a role as the fiber
9.) Look at the sample from the crime scene and the sample from the suspects shoe. Based on your observations, predict whether testing will show that the samples are identical. Record your prediction.
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 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 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.
