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.
By providing mitochondrial DNA haplotype, researchers were able to compare their DNA with that extracted from a microscope slide containing flesh taken from the torso in Crippen's cellar. [30] [31] The original remains were also tested using a highly sensitive assay of the Y chromosome that found the flesh sample on the slide was male. [32]
This was the first use of DNA fingerprinting in a criminal investigation, and the first to prove a suspect's innocence. [96] The following year Colin Pitchfork was identified as the perpetrator of the same murder, in addition to another, using the same techniques that had cleared Buckland.
He concluded that there was no match between the samples and Buckland, who became the first person to be exonerated using DNA. Jefferys confirmed that the DNA profiles were identical for the two murder semen samples. To find the perpetrator, DNA samples from the entire male population, more than 4,000 aged from 17 to 34, of the town were collected.
After 45 years, authorities in California were finally able to tell the Gonzalez family who they believe killed their loved one. The Riverside County Sheriff’s Office used DNA and forensic ...
Lawyers for a New Jersey man charged with the brutal murders of four of his relatives are challenging the use of an increasingly common tool that has transformed DNA analysis in dozens of labs ...
His discovery is first put to use in an immigration case, successfully proving the parentage of a young Ghanaian boy and preventing his deportation. The acceptance of Jeffreys’s findings in a court of law opens the door to DNA testing, and he and his university laboratory are swamped by paternity and immigration cases.
