Colin Pitchfork (born 23 March 1960) is an English child-murderer and child-rapist. He was the first person convicted of rape and murder using DNA profiling after he murdered two girls in neighbouring Leicestershire villages: Lynda Mann in Narborough in November 1983 and Dawn Ashworth in Enderby in July 1986.
Set over a nearly four-year period from 1983 to 1987, DCS David Baker leads an investigation into the vicious murders of the two Leicestershire teenage schoolgirls, Lynda Mann and Dawn Ashworth. Meanwhile, Alec Jeffreys is an ambitious scientist who has recently discovered a remarkable method to read a person's DNA and, from it, generate a ...
The first application of DNA profiles was used by Jeffreys in a double murder mystery in the small English town of Narborough, Leicestershire, in 1985. A 15-year-old school girl by the name of Lynda Mann was raped and murdered in Carlton Hayes psychiatric hospital. The police did not find a suspect but were able to obtain a semen sample.
Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [15] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.
Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [1] AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction ...
Rapid DNA is a "swab in-profile out" technology that completely automates the entire DNA extraction, amplification, and analysis process. Rapid DNA instruments are able to go from a swab to a DNA profile in as little as 90 minutes and eliminates the need for trained scientists to perform the process.
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus ; which is inherited from both parents, and the mitochondria ; inherited maternally.
Low Copy Number (LCN) is a DNA profiling technique developed by the UK Forensic Science Service (FSS) which has been in use since 1999. [1]In the United Kingdom use of the technique was suspended between 21 December 2007 and 14 January 2008 while the Crown Prosecution Service conducted a review into its use – this suspension has now been lifted.
