Colin Pitchfork was convicted of the 1983 and 1986 rapes and murders of two 15-year-old girls in Narborough, Leicestershire, after being identified through DNA fingerprinting, making it the first case in the world to use this technology for a conviction. Pitchfork had initially attempted to evade justice by having a colleague take a DNA test in his place but was ultimately caught following a tip-off. Despite his incarceration, Pitchfork's parole applications have been repeatedly denied due to opposition from the victims' families.
