LONDON — A middle-aged British woman, who somehow came into contact with the Soviet-era nerve agent known as Novichok, died Sunday evening at a hospital in south England where she was being treated for exposure to the military-grade chemical weapon.
Prime Minister Theresa May said she was “appalled and shocked by the death,” and announced that it is now being investigated as a murder.
Dawn Sturgess, 44, was one of five people who became seriously ill after being exposed to the nerve agent in the Salisbury area.
Former Russian spy and double agent Sergei Skripal and his adult daughter, Yulia, were poisoned four months ago in what British authorities deemed a deliberate attack. After reviving from comas, both were released from the hospital to an undisclosed location. A police sergeant involved in the investigation of the March incident was also hospitalized for exposure but released shortly thereafter.
