Pitchfork was arrested, and his blood was sent to Jeffrey's lab for processing and profile development. Another coworker reported the deception to the police. Pitchfork, a local bakery employee, had coerced his coworker Ian Kelly to stand in for him when providing a blood sample-Kelly then used a forged passport to impersonate Pitchfork. In the murder inquiry, led by Detective David Baker, the DNA contained within blood samples obtained voluntarily from around 5,000 local men who willingly assisted Leicestershire Constabulary with the investigation, resulted in the exoneration of Richard Buckland, an initial suspect who had confessed to one of the crimes, and the subsequent conviction of Colin Pitchfork on January 2, 1988.
The process, developed by Jeffreys in conjunction with Peter Gill and Dave Werrett of the Forensic Science Service (FSS), was first used forensically in the solving of the murder of two teenagers who had been raped and murdered in Narborough, Leicestershire in 19.
The first patent covering the direct use of DNA variation for forensics ( US5593832A ) was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981.īritish geneticist Sir Alec Jeffreys independently developed a process for DNA profiling in 1984 while working in the Department of Genetics at the University of Leicester that lead to the first use of DNA profiling in a criminal case. Starting in the 1980s, scientific advances allowed the use of DNA as a material for the identification of an individual. His discovery led to the conviction of Colin Pitchfork in 1988. Sir Alec Jeffreys, pioneer of DNA profiling.
