5.1 R v T (2010) 5.1. a. Case details In this case, T was tried for the murder. Footwear marks were found at the scene of murder and were recovered by Mr Ryder (expert witness). He compared these footwear marks with the trainers found in the appellant’s house after his arrest. Below shown are the results of the comparison made and the explanation given for each result- 1. The type of sole pattern and configuration (size) of the recovered trainers were same as the marks made at the crime scene. It was revealed that the pattern was one of the most frequently encountered patterns. 2. Wear marks on the trainers recovered was greater than that found from the marks. Explanation for this was given that they can be from additional wear of the trainers in the intervening period and it wasn’t known how often trainers were worn. 3. Marks found on the floor of the crime scene showed particular features which might have resulted from damage to the trainers. As the trainers recovered from the appellant didn’t show any of the above features, following explanations were provided which would not exclude the possibility that the marks had been made by the trainers:- a. The marks resulted from an artefact on the surface of the floor. b. The features could have worn away as the trainers were worn for a certain period of time. c. The marks might have been result of a small stone stuck in the trainers, which have dislodged afterwards. (CCRC, 2010) 5.1. b. Result of evidence comparison
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 hair found at the scene was observed under a microscope and it was concluded to be Anna Garcia’s hair. The shoeprint was compared and it also was concluded to being Anna Garcia’s hair. Lastly, the fingerprint contained a radial loop, and the only suspect with a radial loop was Alex
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
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
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.
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.
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,
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 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;
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.
Friction ridge evidence has always been considered infallible in crime investigation and conviction of those involved. Traditionally, latent print examiners have presented identification testimony in courts with an explanation of identification or with a charted enlargement of matching and latent print. [1]
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
Since 1692, bite marks has been used as evidence in courts. Throughout the years, bitemarks has been introduced to many criminal prosecutions and has been used as primary evidence to prosecute many individuals, however, in recent years, the use of bite marks as evidence raises a controversial topic of whether it is accurate and reliable. Although, the use of bite marks as evidence has rightfully convicted many individuals such as Ted Bundy, there are also many cases where individuals are wrongfully convicted. A number of exonerations have also occurred due to incorrect bite mark identification. The use of bite mark as evidence should not be used in courts as there are multiple factors that can provide inaccurate results.
Criminal cases many times call for the examination of evidence that can tie a suspect or victim to a crime scene or to one another. These physical traces frequently include blood and other bodily fluids, hair, fibers, and even bite marks. Here we will focus our attention to the latter and its accuracy, as it applies to the field of forensic science referred to forensic odontology or forensic dentistry.
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.
