Killing of Rachel Nickell
Rachel Jane Nickell (23 November 1969 – 15 July 1992) was a British woman who was stabbed to death on Wimbledon Common in south-west London on 15 July 1992. The initial police investigation of the crime resulted in the arrest in controversial circumstances of an innocent man, who was acquitted. Her killer, Robert Napper, was identified by a later police investigation and convicted in 2008. Nickell was walking with her two-year-old son on Wimbledon Common when she was stabbed multiple times and died at the scene. A lengthy police investigation to find the perpetrator  followed, during which a suspect was wrongfully charged and later acquitted – before the case went cold. In 2002, with more advanced forensic techniques, the case was reopened. On 18 December 2008, Robert Napper pleaded guilty to Nickell's manslaughter on the grounds of diminished responsibility. Napper, who was already detained at Broadmoor High Security Hospital in Berkshire for a 1993 double murder, was ordered to be detained there indefinitely. Killing. At the time of her death, Nickell was living near Wimbledon Common with partner André Hanscombe and their two-year-old son, Alexander Louis. Nickell was 23 years old at  the time of her death. On the morning of 15 July 1992, she and Alexander were walking their dog on Wimbledon Common. Whilst passing through a secluded area of the common, Nickell was attacked. An assailant killed her by repeatedly stabbing and slashing her with a knife, then sexually assaulted her. The assailant fled the scene, leaving Alex physically unharmed in the vicinity. A passer-by found Alex clinging to his mother's body repeating the words "Wake up, Mummy". In a television interview on 7 September 2021 with Lorraine Kelly, discussing the documentary "Death on the Common: My Mother ’s Murder," Alex Hanscombe said after his mother had been attacked, he said to her three times "wake up Mummy" before realising she was "gone" and not playing. He then walked into a clearing on the common, where people saw that he was covered in blood and therefore discovered his mother's body. Investigation. Officers of the Metropolitan Police undertook the investigation, under pressure to find the perpetrator by press coverage and public outrage at the circumstances of the homicide. Thirty-two men were questioned in connection with the killing; the investigation quickly targeted Colin Stagg, a man from Roehampton  who was known to walk his dog on the Common. As there was no forensic evidence linking him to the scene, the police asked Paul Britton, a criminal psychologist, to create an offender profile of the killer. They decided that he fitted the profile and asked the psychologist to assist with designing a covert operation, code-named Operation Edzell, to see whether he would eliminate or implicate himself. This operation was later criticised by the media and the trial judge as effectively a "honeytrap". Operation Edzell. An undercover policewoman from the Metropolitan Police Special Operations Group (SO10) contacted Stagg, posing  as a friend of a woman with whom he used to be in contact via a lonely hearts' column. Over five months, she attempted to obtain information from him by feigning a romantic interest, meeting him, speaking to him on the telephone and exchanging letters containing sexual fantasies. During a meeting in Hyde Park, they spoke about the Nickell homicide, but he later claimed that he had only played along with the topic because he wanted to pursue the romance. Profiler Paul Britton later said that he disagreed with use of the fantasy-filled letters and knew nothing of them  until after they had been sent. The undercover female police officer won his confidence and drew out fantasies from him that psychologist Paul Britton interpreted as "violent", but he did not admit to the killing. Police released a taped conversation between the police-officer and him in which she claimed to enjoy hurting people, to which he mumbled: "Please explain, as I live a quiet life. If I have disappointed you, please don't dump me. Nothing like this has happened to me before". When she went on to say, "If only you had done the Wimbledon Common murder, if  only you had killed her, it would be all right", he replied: "I'm terribly sorry, but I haven't". Trial. When the case reached the Old Bailey, Mr Justice Ognall ruled that the police had shown "excessive zeal” and had tried to incriminate Stagg by “deceptive conduct of the grossest kind". He excluded the entrapment evidence and the prosecution withdrew its case. The judge threw the case out and Stagg was acquitted in September 1994. Keith Pedder, the case's lead detective, received heavy public criticism. Even after Stagg was, rightfully as it turned out, cleared of the murder  of Nickell, Pedder continued in subsequent years to wrongfully promote his theory that Stagg was guilty, telling an ITV "Real Crime" documentary in 2001: After Stagg's acquittal, Pedder took early retirement from the police and later faced corruption charges, although these were subsequently thrown out by the judge in the pre-trial hearing on the grounds of insufficient evidence. Reinvestigation and conviction. Cold case review. Every year on the anniversary of the killing Scotland Yard came under pressure for progress. In the late 1990s, Nickell's murder was re-investigated as part of Operation Engima, which was a national  cross-force investigation into the unsolved murders of 207 women. Under new management, detectives began to collate evidence and files related to the case from 2000. In 2002, ten years after the killing, Scotland Yard used a cold case review team, which used refined DNA techniques only recently made available. A small team of officers and retired veteran investigators analysed statements from witnesses, reassessed files on a number of potential suspects and examined the possibility that the case was linked to other crimes. Officers compared the injuries suffered by Nickell with other attacks and consulted forensic scientists about improvements in  DNA matching. In July 2003, reports surfaced that, after 18 months of tests on Nickell's clothes, police had found a male DNA sample which did not match her boyfriend or son. The sample at the time was insufficient to confirm an identity, but was large enough to rule out suspects. Robert Napper. In July 2006, the Scotland Yard team interviewed convicted murderer Robert Napper for two days at Broadmoor. Napper, 40 years of age at that time, had been diagnosed as having paranoid schizophrenia and Asperger syndrome and had been held at the secure institution for more than ten  years. He had been convicted of the murder of Samantha Bisset and her four-year-old daughter Jazmine in November 1993, 16 months after Nickell's homicide. On 28 November 2007, Napper was charged with Nickell's murder. He appeared at City of Westminster Magistrates' Court on 4 December 2007, where he was granted bail on condition he remained at Broadmoor psychiatric hospital until another hearing on 20 December 2007. On 24 January 2008, he pleaded not guilty to Nickell's murder and the trial started on 11 November 2008. On 18 December 2008, at the Old Bailey, Napper pleaded  guilty to the manslaughter of Rachel Nickell on the grounds of diminished responsibility. Mr Justice Griffith Williams said that Napper would be detained indefinitely at Broadmoor because he was "a very dangerous man". It is unlikely he will ever be released. At the same time, Stagg received a public apology from the Metropolitan Police for their previous involvement and prosecution of him in regard to the Nickell murder investigation. Aftermath. An internal review estimated that the pursuit had cost the public £3 million and that vital scientific information had been missed. Stagg sued the police for damages totalling £ 1 million following the 14 months he spent in custody. He has co-written and published two books about the case, "Who Really Killed Rachel?" (with novelist David Kessler) and more recently, "Pariah" (with journalist Ted Hynds), the latter being published on the same day as the real culprit's appearance in court to enter a plea. The undercover female police officer involved in the attempt to obtain evidence in the original investigation by befriending him, resigned from the Metropolitan Police force in 1998, taking early retirement. With the support of the Police Federation she too sued the Metropolitan Police  for damages arising from the investigation. In 2001, shortly before it was due to be heard, her case was settled out of court and she received £125,000. Her solicitor said: "The willingness of the Metropolitan Police to pay substantial damages must indicate their recognition that she sustained serious psychiatric injury". The payout was widely criticised by various sources, particularly as Nickell's son had been granted £22,000 (less than a fifth of the amount paid to the undercover detective) from the Criminal Injuries Compensation Authority. The criminal psychologist involved with the investigation was charged with professional misconduct by  the British Psychological Society, but in 2002, in lieu of any substantive hearings, further action was dismissed due to the time delay in bringing proceedings. André Hanscombe later wrote a book titled "The Last Thursday in July", about his life with Nickell, coping with the homicide and life with their son afterwards. In 1996, he moved with their child to France, driven abroad, according to notes in his book, by media intrusion. He was strongly critical of some of the reporters who tracked him and his son down to his "sanctuary" in the French countryside. In January 2007, the Home  Office confirmed that Stagg would receive compensation for wrongful prosecution, with the amount to be set by an independent assessor. On 13 August 2008, it was announced that the compensation was £706,000. IPCC findings. Following an investigation, the Independent Police Complaints Commission (IPCC) released a report, dated 3 June 2010, into the actions of the Metropolitan Police Force and their handling of the murder investigation. It described a "catalogue of bad decisions and errors" by the Metropolitan Police which had resulted in Napper being free to kill Nickell. It said that officers missed a series of opportunities to take  him off the streets and suggested the lives of Samantha Bisset and her four-year-old daughter Jazmine would also have been saved if police had acted on tip-offs, including one by Napper's mother. Rachel Cerfontyne, of the IPCC, said that police failed to investigate the 1989 report that he attacked a woman on Plumstead Common, in London and no record of the telephone call can be found. She said: "It is clear that throughout the investigations into the 'Green Chain' rapes and Rachel Nickell's death there was a catalogue of bad decisions and errors made by  the Metropolitan Police. The police failed to sufficiently investigate after Napper's mother called police to report that he had confessed to her that he had raped a woman and, inconceivably, they eliminated Napper from inquiries into the Green Chain rapes because he was over 6ft tall. Without these errors, Robert Napper could have been off the streets before he killed Rachel Nickell and the Bissets, and before numerous women suffered violent sexual attacks at his hands". Detectives had decided to exclude anyone over 6' based on the description of a 5' 7" rapist; however, there were conflicting witness  reports of the rapist's height and Napper walked with a stoop. The IPCC said no police officer would face disciplinary action because they had all retired and one key senior detective had died. Criminal prosecutions were not considered.
