The Blooding: Origins of DNA Proofing is based on the original true crime novel The Blooding by Joseph Wambaugh, originally published in 1989. The book tells the story of how DNA proofing technology was introduced and how this technology solved the largest manhunt in British crime history. Within three years, two schoolgirls were savagely raped and murdered and their bodies found along a shady footpath in Narborough, a village in Leicestershire, England. Only with a scientific breakthrough by taking blood samples (a process known as ‘the blooding’) of more than four thousand men could Colin Pitchfork be proven guilty and later convicted of the crimes.This Netflix series would follow the similar narrative of the book with interviews from the case detectives, local media, and the scientists behind the ‘blooding’ process. These interviews would offer more in-depth knowledge that confirms Wambaugh’s journaling of the case, including some up-to-date information on the lasting impact of the case today.
