Timothy Bridges Victim: Timothy Bridges Suspect: Timothy Bridges How the hair fiber made a connection to the case? The hair analysis helped prove that Bridges was not the actual person who committed the crime. After 25 years of him being in prison they found him innocent because of hair evidence.
Crime scene investigators noted signs of a struggle left under Estelle’s nails. After it was already too late, DNA testing determined the skin found under her fingernails was not a match to Blair but rather a match to the other suspect at the time of the original investigation. The expert DNA testimony at Blair’s trial consisted of fibers and hair found in his vehicle, on his person, and at an unrelated park was circumstantial and eventually disproven by DNA
In the wake of testing six different substances with three different pointers, we presumed that the obscure substance was headache medicine such as, Aspirin. The hair found at the crime scene had a place with Anna; this was found via painstakingly looking at every person of interest's' hair under a magnifying instrument and contrasting them with the hair found at the crime scene. The fingerprint on the bottle of the drink was Alex Garcia's and this was figured out by recognizing every person of interest's' sort of fingerprint and the fingerprint found at the crime scene coordinated Alex's. The sloppy shoe print that was at the crime scene has a place with Anna's
There was no blood. And so there was no way to conduct a conclusive DNA test. But there was that strand of hair. At a key stage in the 1992 rape and burglary trial.
#2 Name of case: 1977 Cold Case Murder Solved by a Hair Victim: James Anagnos Suspect: Frank Wright Impact of hair: A hair was found in the victim's hand and was tested and matched to the hair of Frank Wright. However, Wright passed away in 2002 which was before they ruled him as the murderer. #3 Name of Case: DA says fiber evidence
Wayne Williams was found guilty of the killing of two people. Even years after William’s still tries to persuade the idea of him being innocent. Just like fingerprints, hair analysis is following the same path. I think that DNA fingerprints will become bigger and more accurate of accusing killers, the use of hair analysis will decrease, but I do not think hair analysis should be taken away.
Hairs: Name of the case: The murder of James Anagnos Victim: James Anagnos Suspect: Frank Wright How the hair made a connection for the case: James Anagnos was found dead in her restaurant with a handful hair. DNA analysis, later, found the hair was Frank Wright but detectives only were able to create him a suspect after they found put him and the victim had an argument before closing that night- along with the hair. Name of the case: The murder a cab driver Victim: A unknown cab driver Suspect: Santae Tribble How the hair made a connection for the case: A case from 1978 involved a murder in Washington D.C.
Case: 1977 Cold Case Murder (Hair) Victim: James Anagnos Suspects: Frank Wright How did the hair sample help? At first the hair sample could not match back to Frank Wright. It took years for new technology to finally match Wright.
Introduction The FBI has done two case reviews on hair analysist. One of these reviews were done in 1996 and the other is still on going. The latter review came about because of three exonerations. One of these exonerations was that of a DC man, Santae Tribble.
Wayne Williams Essay Hair and fibers seem like tiny useless objects,but they have a huge impact when it comes to forensic investigations. Hair strands and fibers hold more information than we can see. For example hair can tell where you have been,what you have eaten, and what race you are. Also DNA can be pulled from strands of hair.
A comparative analysis was conducted between the portion of twigs found on Saunders’ hair and the wooden floor of the apartment rented to Leggette and Henneberry. The portion of twigs fit in the wooden floor of the dining room in a perfect re-alignment. (Leggette, 2014) Although comparative analysis clued the suspects related to the crime, the most effective evidence used in this crime was fingerprinting, an individual characteristic that attains an extreme high probability of associating the evidence found and gathered to the person or persons who committed the
The deciding factor and only admissible evidence in Jones’ conviction came down to a strand of hair that was found at the scene of the crime. A forensic expert testified that the hair appeared to have come from Jones; however, he was unable to match
There was multiply evidence that, traced back to O.J. Simpson. His blood was recovered and fingerprints were local on the back fence. Later they found his hair in a knit hat at the crime scene, which the same kind of fiber was found on Goldman’s clothing. Fibers from simpson’s car were also similar to the knit hat. In his vehicle, he had blood from both victims and a pair of bloody socks in his house, along with the right glove that was missing from the crime scene.
In the lab report three students are tested along with one suspect. Student number two’s DNA matched the suspects DNA. The student’s DNA’s are cut with five different enzymes as well as the suspects DNA. Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.
DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
