British woman dies after exposure to nerve agent

SALISBURY— British police rushed to solve a murder mystery on Monday after a woman died following exposure to the nerve agent Novichok, four months after the same toxin was used against a former Russian spy in an attack that Britain blamed on Moscow. Prime Minister Theresa May said she was “appalled and shocked” by the death of Dawn Sturgess, a 44-year-old mother of three who had been living in a homeless hostel in the city of Salisbury in southwest England. Sturgess and Charlie Rowley, 45, fell ill last weekend in the town of Amesbury, near Salisbury, the city where former double agent Sergei Skripal and his daughter, Yulia, were attacked with the Novichok nerve agent in March and have since recovered.
