By Darren Boyle A retired murder squad detective who attended the scene of 'body in the bag spy' Gareth Williams said he believed the MI6 man could have been poisoned. Former Detective Chief Inspector Colin Sutton was the most senior officer on the scene when he arrived at Mr Williams' flat in Pimlico on August 23, 2010. An inquest at Westminster Coroner Court found Mr Williams was most likely 'unlawfully killed', but police officially believe the spy died after padlocking himself inside the bag. Former Detective Chief Inspector Clive Sutton, pictured, said he believed the death of Gareth Williams could have been 'the perfect murder'
