Relatives gave the sound moderator back to the police (Peter Eaton handed sound moderator to DS Jones, on evening of 12th August 1985), but on some day prior to 30th August 1985, Essex police handed the sound moderator back to the relatives, which in turn enabled Ann Eaton to hand back the sound moderator to DC Oakey on the 11th September 1985...
