Police Believe Dead Spy Killed in Sex Game Toxicology report comes up empty for MI6 agent found in bag By Kevin Spak, Newser Staff Posted Oct 28, 2010 12:18 PM CDT 4 comments Comments This undated image made available in London Wednesday Sept. 1, 2010, by the Metropolitan Police, shows British code breaker Gareth Williams. (AP Photo/Metropolitan Police, ho) (Newser) – Police have hit a dead end in the strange case of Gareth Williams, the MI6 codebreaker whose naked, decomposing body was found inside a locked sports bag in his bathroom. Toxicology reports have revealed no trace of drugs, alcohol or poison, sources tell the Daily Telegraph, and since there’s no evidence of any other cause of death, officials now suspect he died in a sadomasochistic sex game. With seemingly every other possibility exhausted, officials now believe someone locked Williams in the bag as part of a bondage exercise, but then left him there to die of suffocation and dehydration. The North Face bag he was locked in was made from durable material with reinforced seams, which would have made it nearly impossible to escape from, and so hot that Williams probably passed out.
