His body was stuffed in a locked duffel bag, and the police think his death may be suspicious?
Piffle. It’s an obvious case of accidental suicide while trying to hide from an annoying neighbor:
Jeff Stein, the Washington Post’s SpyTalk blogger, says that unnamed “U.S. intelligence officials” have downplayed the possibility that British code-breaker Gareth Williams – who worked closely with the U.S. National Security Agency at Fort Meade and American intelligence officials in Kabul – was assassinated.
But back in London, where the naked, decomposing body of the 31-year-old “math genius” was found August 23 in a padlocked duffel bag in the bathroom of an apartment kept as a “safe house” by Britain’s M16, police are not so sure.“Murder detectives say they are still looking at whether Gareth Williams may have been killed by a foreign intelligence agency seeking to stop his work on intercepting messages and code-breaking,” according to the Daily Telegraph.
Williams was “on loan” to M16 from Britain’s top-secret Government Communications Headquarters (GCHQ), and reportedly played a “key role” overseeing Echelon, a secret electronic network that links satellites and super computers in Britain, the U.S. and other Western allies that eavesdrop on terrorist networks.
Nothing to see here, move along…
