suspect. Before this was accomplished, however, this new technique was tested in animals to confirm its validity and used in immigration disputes as well as paternity testing. Through the use of Jeffreys’ new technique, upon comparing the DNA of the kitchen porters to the semen found on both girls, it is found that the kitchen porter is not the culprit. After discovering this, the search for the killer began again. Detective Pearce and the officers begin the investigation by testing the DNA of over 4,000 men. After months of testing the DNA of thousands of men, the murder was traced to Ian Kelly, one of the two local bakers. After mistakenly arresting him, police discovered that the blood given for Colin Pitchfork was actually that of Ian Kelly and found that Colin Pitchfork was actually responsible for the murder of Lynda Mann and Dawn Ashworth. Alec Jeffreys discovered the variation in DNA, termed RFLP’s, resulting from variations in base pairs showing up at around 10,000,000 sites. This work led to the discovery of even more highly variable stuttered regions, termed minisatellites, in which the number of stutters leads to variation. The discovery of both types of variation in DNA led Jeffreys to the accidental discovery of DNA fingerprinting. With this new technique came the ability to distinguish every individual based on variations in the DNA sequence. His work with DNA fingerprinting was used in the investigation of the two murders in Narborough to identify…

Mr. McGregor is one of the suspects that killed Peter according to many valid reasons and proof. First off, Peter had three stabs on his back, which means a weapon that killed Peter must consist of three blades.The first theory is the pitchfork which leads to Mr. McGregor. Farmers are known for having a pitch fork, therefore the tool allowed Mr. McGregor to kill Peter. To continue on, according to an assumption, the pitchfork was found in the pond near the McGregor’s farm. This proves that the…

Evaluating Passionate Text: Significance of the Chestnut Tree in Jane Eyre The thunder rumbled through the clouds and as a sudden streak flashed across the sky; the lightning violently hit the tree and the repercussions of this (God-like) action had little arcs that danced across the thick, black sky. The tree hung in despair and disbelief, almost as if it were a weeping willow instead of a horse chestnut tree. In Charlotte Bronte’s Jane Eyre, “the chestnut tree is hit by lightning on the…

considered a visionary for many different reasons, but the main reason he is known as a visionary for is his passion for innovation. “Benioff has been widely recognized for his visionary leadership and pioneering innovations.” (Unknown 2016). He is considered a social activist because he has a strong passion for social change. Which brings us to the next topic of his 1:1:1 model. “Benioff created the 1-1-1 model of philanthropy, which leverages the resources of Salesforce to improve communities…

My Access #2 There could be a lot of meanings to the quote by Colin Wilson. There could be different experiences, and also some different views on what the quote is trying to tell us. Many people might not understand the quote because they don’t know what it’s like to actually come back from failure because they had everything given to them. What I get from the quote by Colin Wilson is that average humans are used to being in some bad situations because they don’t want to try their hardest. I…

In almost every society that had been established before the 1900th century, there were laws or rules governing men and women and how each should be treated. Women, as seen in these societies, were looked down upon and not treated equally as men did. Men held most of the rights that every person should have and left women with basic human rights. Throughout most of the duration of these civilization, the status of women in relation to that of men didn’t change and men were always seen as…

DNA fingerprinting is a process used to tell the difference between people by using samples of their DNA. This process has been a huge factor in cases like the Mann vs. Pitchfork case in 1986. A fifteen year old girl, Lynda Mann, was abducted in England. Her body was found raped and murdered in a ditch the next day. Three years later, near the same location, another woman was the victim of the same occurrence by a man named Richard Buckland. Forensics specialists to test the suspect's DNA but…

Dr. Jeffreys used the DNA fingerprinting technique that he had developed years earlier to crack the Colin Pitchfork case. In this case, “two 15-year-old girls by the names of Lynda Mann and Dawn Ashworth, were sexually assaulted and brutally murdered in close proximity to each other” (Buckleton et al. 1). “ In 1983, the 5 feet 2 inches, 112 pound body of Lynda Mann was discovered on a frosty lawn by the Black Pad footpath in the ancient village of Narborough in Leicestershire, England”…

murder case of Colin Pitchfork was the first murder conviction based on DNA profiling. Lyna Mann, of 15 year old schoolgirl was raped and murdered in the grounds of Carlton Hayes psychiatric hospital in Narborough, Leicestershire (England) in November of 1983. There was a forensic examination done on the semen found on Lynda, and it showed that that type of seamen was found in only 10% of men. In 1986, another 15 year old girl, Dawn Ashworth, was similarly sexually assaulted and strangled in a…

Fourth Amendment protections against unreasonable search and seizure. Keywords: DNA, Fourth Amendment, SCOTUS DNA Collection v. The Fourth Amendment DNA was first discovered in 1869 by Friedrich Miescher, a Swiss physician. It was not until 1953 that James Watson and Francis Crick developed the first widely accepted model of the structure of DNA – the double-helix. It would be another thirty four years before their discovery was put to use for the purpose of criminal investigation. The first…
