The death of British spy Gareth Williams, whose naked body was found in a locked sports equipment bag, will not be ruled an unlawful killing, a coroner said. Coroner Dr. Fiona Wilcox said she would provide a statement of facts but would not give a definitive cause of the circumstances of Williams\' death, The Daily Telegraph reported. Williams was a 31-year-old code breaker for Britain\'s Military Intelligence Service, known as MI6, which supplies the British government with foreign intelligence. He was found dead in 2010 in his home in Pimlico, a neighborhood in London. His decomposing body was in a padlocked bag normally used to hold large sports equipment. Police, who have no suspects in Williams\' death, are certain a third party was involved, the Telegraph said. Experts on confined spaces and pathologists have concluded Williams was probably alive when he went into the bag and died soon after. Williams would have suffocated within 3 minutes if he had been alive when he got inside the bag, pathologists said. Dr. Benjamin Swift, a Home Office pathologist, has said poisoning and asphyxiation are possible causes of Williams\' death, the BBC reported.
