A woman poisoned by a militarygrade nerve agent in England died Sunday, eight days after police think she touched a contaminated item.

London police said the case has become a homicide investigation now that Dawn Sturgess, 44, has died in a hospital in Salisbury. She and her boyfriend, Charlie Rowley, 45, were admitted June 30.
