Police have launched a murder inquiry after Dawn Sturgess died following exposure to the nerve agent Novichok in Wiltshire. Her relatives are receiving support from specially-trained family liaison officers. Professor Paul Cosford said, ‘As a precaution we still advise the public not to pick up any strange items such as needles, syringes or unusual containers.’ The death of Dawn Sturgess, a British citizen on British soil, now changes the investigation to a murder inquiry, with all the diplomatic and security implications that carries as Britain blames Moscow for the original attack in March.
