Death of Gareth Williams

Originally from Anglesey, Wales,[5] Williams, who spoke Welsh as a first language, began studying mathematics part-time at Bangor University, while still at Ysgol Uwchradd Bodedern, and graduated with a first-class degree at age 17.[6] After gaining a PhD at the University of Manchester, he dropped out from a subsequent post-graduate course at St Catharine's College, Cambridge,[7] and took up employment with GCHQ in Cheltenham in 2001,[8] renting a room for a decade in Prestbury, Gloucestershire. Reportedly an intensely private man and a keen cyclist, Williams was due to return to Cheltenham at the beginning of September 2010 after his annual leave.[9]

Police visited Williams's home during the afternoon of Monday 23 August 2010, as a "welfare check" after colleagues noted he had been out of contact for several days.[10] His decomposing naked remains were found in a red The North Face bag, padlocked from the outside, in the bath of the main bedroom's en-suite bathroom.[11][12] The police had gained entry into his top floor flat in Alderney Street, Pimlico at around 16:40.[13] His family alleged that crucial DNA was interfered with and that fingerprints left at the scene were wiped off as part of a cover-up.[1] No fingerprints, palm-prints, footprints or traces of Williams's DNA were found on the rim of the bath, the bag zip or the bag padlock. A key to the padlock was inside the bag, underneath his body.[14]

Williams was buried at Ynys Wen cemetery in Valley, Anglesey, on 26 September 2010, following a private funeral service at Bethel Chapel in Holyhead attended by his family, friends, former colleagues in the intelligence services, and also by the head of SIS, Sir John Sawers.[15][16][17]

Williams's date of death was estimated to have been in the early hours of 16 August, one week before he was found.[18]

Vincent Williams from the Metropolitan Police informed the Westminster Coroner's Court that experts were agreed that it was impossible for Gareth Williams to have locked himself in.

Soon after the investigation started, the heads of the Secret Intelligence Service and Metropolitan Police met to discuss how the police would handle the investigation in light of the top secret nature of Williams's work, and who would lead the investigation. Williams had recently qualified for operational deployment, and had worked with U.S. National Security Agency and FBI agents. The U.S. State Department asked that no details of Williams's work should emerge at the inquest. The Foreign Secretary, William Hague, signed a public-interest immunity certificate authorising the withholding from the inquest of details of Williams's work and U.S. joint operations.[15]

After launching an investigation, coroner Fiona Wilcox said that there were no injuries on his body and no signs that he had been involved in a struggle; his body was also free of alcohol and common recreational drugs.[19][20][21] The Metropolitan Police considered his death "suspicious and unexplained".[22] The FBI also conducted their own investigation into the case.[23]

In December 2010, police released further details, stating that Williams had visited a number of bondage websites although at the later inquest it was stated these visits were "sporadic and isolated" and accounted for only a small proportion of the time he spent online. It was also noted at the inquest that he never visited any website devoted to claustrophilia – a sexual interest in being confined in small spaces.[24]

An expert brought in to examine the bag in which Williams's body was found concluded that Williams could not have locked it. A police spokesperson stated that: "If he was alive, he got into it voluntarily or, if not, he was unconscious and placed in the bag."[25]

The heating in Williams's apartment was found to be turned on.[24] It has been suggested an elevated temperature inside the apartment would have sped up the decomposition of Williams's body.

Subsequently, the police released an E-FIT photo of two people they were seeking, who were seen to enter the communal entrance of his home in June or July 2010.[25]

The lawyer for the family, Anthony O'Toole, at the Coroner's inquest in March 2012, said that a second person was either present when Williams died, or someone broke in afterwards and stole items. There is no forensic evidence to support this view. No sign of forced entry could be found, but it was also noted that the door and locks had been removed by the time police experts had become involved.

DNA found on Williams's hand turned out to be contamination from one of the forensic scientists and the police determined that a Mediterranean couple they had been seeking had nothing to do with the inquiry.[26] LGC, the forensic company, apologised that the error had inflicted such pain on the family, caused by the incorrect data entry of a numerical code.[1]

Evidence at the inquest showed that it would have been virtually impossible for Williams to have locked himself in the bag.[27] Two experts were unable to lock themselves in a similar bag despite making 400 attempts to do so, although one stated there was a small chance Williams had managed the feat.[24] Pathologist Richard Shepherd stated it was more likely that Williams was alive when he got into the bag, due to the difficulty of arranging a corpse in the position Williams's body was found in. Another pathologist stated that Williams would have been overcome by hypercapnia, elevated carbon dioxide levels, after only two or three minutes in the bag.[24]

Williams's family said they believed that a secret service agency was involved in his death.

Fiona Wilcox, the Coroner, said that she would "follow the evidence" wherever it led.[1]

Evidence given by Williams's former landlady in Cheltenham showed that one night he had awoken her and her husband, screaming for help. Apparently he had managed to tie himself to his bed, and required assistance in releasing himself. The testimony was that Williams had claimed at the time that he had done it just to see if he could free himself and that he promised not to try this again. Nothing further had been said about the incident since between Williams and his landlady.[28]

Evidence was given of £20,000 worth of women's clothing being found in the flat.[29]

Journalist Duncan Campbell reported that the inquest evidence indicated Williams was one of a team of intelligence officers sent to penetrate US and UK hacking networks. He had attended the 2010 Black Hat Briefings and DEF CON conferences. He had started with SIS in London in spring 2009, and after taking a number of training courses started on "active operational work".[8] A few months before his death, he asked to return to GCHQ as he disliked the "rat race, flash car competitions and post-work drinking culture" at SIS and as a keen cyclist and walker wanted to go back to the countryside, and was due to return in September.[30]

The finding by Westminster coroner Dr Fiona Wilcox prompted a reinvestigation by the Metropolitan Police lasting a further 12 months which officers said had been allowed unprecedented access to serving MI6 staff following strong criticism at the inquest of the spying agency's actions following the death of Mr Williams.

Metropolitan Police Deputy Assistant Commissioner Martin Hewitt announced that despite a re-examination of all evidence and the investigation of new leads no definitive answers had been obtained as to the cause of Williams's death and the "most probable scenario" was that he had died alone in his flat in Pimlico, central London, as the result of accidentally locking himself inside the bag.[33][34]

In September and October 2015, Boris Karpichkov, a former KGB agent who defected from Russia and who now lives in Britain, stated during interviews that "sources in Russia" have claimed that the Russian Foreign Intelligence Service, also known as the SVR, was responsible for Williams's murder. According to Karpichkov, the SVR tried and failed to blackmail Williams into becoming a double agent.[35]

In response to the SVR's attempts, Williams apparently claimed that he knew "the identity of a Russian spy inside the GCHQ." Karpichkov claimed that Williams's threat meant that "the SVR then had no alternative but to exterminate him in order to protect their agent inside GCHQ." Regarding the cause of death, Karpichkov claimed that the SVR killed Williams "by an untraceable poison introduced in his ear."[36][35]

The 2015 BBC Two television series London Spy is loosely based on the Gareth Williams case. The miniseries stars Ben Whishaw as Danny, who is accused of murder after his partner, MI6 spy Alex, is found dead inside a locked trunk.[37][38]
