Codebreaker: Gareth Williams
12 April 2012
Detectives investigating the death of MI6 codebreaker Gareth Williams are searching for a second person who they believe may have been present when he died.
Police suspect the agent may have been engaged in a sex game that went wrong and are moving away from the possibility that he was murdered. One theory is that the 31-year-old had engaged in a sadomasochistic game.
His naked body was found in a holdall bag in his Pimlico flat last month.
