They had a suspect, Ray Krone. In the morning, the bar owner came to open the bar. He saw that the bar doors were open so he walked into the men's bathroom and saw Kim's body lying on the ground unconscious. The first thing that they saw was that her body had a bite mark on her body. The police called in a Forensic odontologist to analyze the bite mark on Kim's body.
His conviction was overturned after a DNA test excluded Adnan’s DNA from Hae’s body at the time of the murder. The case of Hae Min Lee’s murder and Adnan Syed’s conviction highlights the critical importance of thorough and unbiased criminal investigations, emphasizing how necessary it is for rigorous evidence collection,
Based on the facts in the case, it would be difficult to determine her killer, eventhough physical evidence was found, the killer is unknown to this day. In the student’s opinion, it is impossible to pinpoint who the actual killer, but suspicions lead to her brother Burke Ramsey. However, the physical evidence also led to the parents also. This case was speculated to have had many errors and was mishandled by some legal authorities. There physical evidence was apparent none which led to who committed this murder.
The murder case of Leanne Holland exposed the ways in which forensic science were both a help and a hindrance to the conviction and subsequent overturning of the verdict, against Graham Stafford. The body of 12-year-old Leanne Holland was found battered and partially naked in scrub 30m off Redbank Plains Rd on September 26, 1991. She went missing on Monday morning on September 23, 1991. According to descriptions, she was last seen wearing a long-sleeved purple jumper, black skirt and no shoes as she headed towards shops just 500m from her Alice St home in Goodna.
Andreasson, M. Nilsson, B. Budowle, H. Lundberg and M. Allen explained “Biological evidence materials found at a crime scene are sometimes degraded or yield insufficient quantities of DNA to enable a successful autosomal STR analysis. These samples are often analysed by sequencing of mitochondrial DNA (mtDNA) due to its high copy number per cell.” Though Mitochondrial DNA was adequate in this case due to the positive RFLP Typing Analysis found in the samples of Laura’s brother and mother it is generally used as a last resort when other DNA Typing tests are not available. This is because “Mitochondrial DNA does not approach STR analysis in its discrimination power.” Societal Impacts and Legal
Author, Anita Larsen, in her nonfiction textbook article “The Murder with No Body” about a murder solved without an actual victim writes to inform young adults about the role of forensics in solving crimes by using the case of Helen McCourt in a serious tone. This author supports her central idea very successfully. She supports her claim by introducing the case of Helen McCourt, whose disappearance was unexplained and suspicion of foul play could not be proven. She next proceeds to show that a name in the victim's diary led the investigators to blood stained clothes in the possession of Ian Simms, but the inability to prove that the clothes were McCourt’s halted the investigation. Additionally, she explains that the use of genetics had to
The prosecution knew it wasn’t Miguel’s DNA on Lopez yet they still convicted Miguel (Owens and Dempsey). This show how the prosecution disregarded the DNA evidence at the time of the investigation. Secondly, the prosecution believed the fetus inside the victim was Roman’s but after DNA testing they found it was not his (Owens and Dempsey). The authors
My DNA Case focus on Li Yun (Lisa) Peng who was believed to murder her husband’s, Jim Peng mistress and son. The victims of the are 25 years old, Jennifer Ji and her five month old son, Kevin. That the crime scene, Jennifer Ji appears to be a victim of rape or attempted rape as her panty were pull down. Jennifer Ji was found dead from eighteen stab wounds and her son, Kevin, was wrapped in blanket dead. The strong piece of evidence was DNA found on the Jennifer Ji’s left arm from a bite wound.
The impact of Tim’s case was also felt on a national and even international level, as it shed light on the importance of using accurate and scientific evidence in the legal system and the need to reform the criminal justice system to prevent wrongful convictions. Tim’s story has inspired many other cases to be re-opened and re-examined, leading to the exoneration of several other innocent individuals. Overall, the case of Tim Cole has had a profound impact on the criminal justice system and has helped to bring about important changes in the use of DNA
Although, in our lab report, suspect ones DNA matched the crime scene when cut with enzyme one, this can be explained by how closely related the two suspects are. Therefore two enzymes were used to cut the DNA; the suspect has to match both. Moreover, the limitation to DNA fingerprinting is, if a person were to have an identical twin. This is because identical twins have the same DNA because they come from the same egg. If a suspect’s DNA matched that of the one being tested, and they had an identical twin, a farther investigation would need to be done.
Murders that are left unsolved leaves family members puzzled and wondering. It is important that we solve murders so we can stop the victim from doing it again. I already know a bit about DNA evidence from my KWL chart crime research, but I would need to learn more about its specific application in cold cases. In my preliminary research, I learned that DNA has helped solve many cold cases over the years. There have been cases where decades-old evidence was retested with updated technology and resulted in identifying the victimizer.
The one key physical piece of evidence linking Scott Peterson to the murder of Laci is the 6-inch dark strand of hair found wrapped around pliers on Scott’s fishing boat(Vries, 2003). Ultimately, the discipline that led to the death sentencing of Scott Peterson was Mitochondrial DNA determined to be that of Laci Peterson in the dark hair strands on his pliers(Vries, 2003). Mitochondrial DNA testing has been around many years dating back to its use of identifying the causalities of the Vietnam War and victims of the 9/11 attacks(Vries, 2003). There have been admissions of computer glitches and routine failure of lab equipment in the past, but this method is widely accepted across the nation as admissible evidence(Vries, 2003). Mitochondrial DNA testing cannot particularly identify someone, but it can statistically conclude when compared to a relative’s DNA a likely match(Vries, 2003).
D Assessment DNA technology Forensic testing 24.11.2014 Marius Martinsen 10D Introduction: I have chosen to investigate Forensic testing, it is also known as DNA profiling or genetic fingerprinting. During this essay I will discuss what the disadvantages and what the advantages of forensic testing are. I will also talk about how forensic testing is carried out. Forensic testing is used to identify an individual by using the DNA sequences of that person.
This DNA sample was tested to determine if the DNA left on Mary Sullivan was a match. This proved to not be a match. This shows some suspicion to the final verdict of the
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.
