to report her missing. Two days later, her body was found in a wooded area near a footpath called Ten Pound Lane. She had been beaten, savagely raped and strangled. The modus operandi matched that of the first attack, and semen samples revealed the same blood type. An initial suspect was Richard Buckland, a local 17-year-old with learning difficulties who, while innocent of both crimes, revealed knowledge of Ashworth's body, and admitted to the Ashworth crime under questioning, denying the first murder. DNA profiling In 1985, Alec Jeffreys, a genetics researcher at the University of Leicester, developed DNA profiling along with Peter Gill and Dave Werrett of the Forensic Science Service (FSS). Gill commented: Using this technique, Jeffreys compared semen samples from both murder victims against a blood sample from Buckland and conclusively proved that both girls were killed by the same man but not by Buckland. Buckland became the first person to have his innocence established by DNA fingerprinting. Jeffreys later said: Leicestershire Constabulary and the FSS then undertook an investigation in which more than 5,500 local men were asked to volunteer blood or saliva samples. This took six months, and no matches were found. Arrest and conviction On 1 August 1987, one of Pitchfork's colleagues at the bakery, Ian Kelly, revealed to fellow workers in a Leicester pub (The Clarendon) that he had taken the blood test while masquerading as Pitchfork. Pitchfork had told Kelly that he wanted to avoid being harassed by police because of prior convictions for indecent exposure. A woman who overheard the conversation reported it to police. On 19 September 1987, Pitchfork was arrested. During questioning, Pitchfork admitted to exposing himself to more than 1,000 women, a compulsion that began in his early teens. He later progressed to sexual assault and then to strangling his victims. Pitchfork said this was in order to protect his identity. The Crown rejected this, viewing the motivation for the strangulations as ‘perverted sadism’. During his interviews with the police he admitted his crimes, but lied about the level and nature of the violence he had inflicted on his victims. He pleaded guilty to the two rapes and murders in addition to another incident of sexual assault, and was sentenced to life imprisonment. A psychiatric report prepared for the Court described Pitchfork as possessing a psychopathic personality disorder accompanied with a serious psycho sexual pathology. The Lord Chief Justice
