The first pictures of a policewoman shot dead in Canada's worst mass killing in over 30 years have emerged. A gunman, who at one point masqueraded as a policeman, killed at least 16 people in the Canadian province of Nova Scotia during a 12-hour rampage, authorities said on Sunday.
Among the victims of the shooting spree that spread across part of the Atlantic Canadian province was RCMP officer Heidi Stevenson, a 23-year veteran of the force with two children.
The Royal Canadian Mounted Police said the gunman, 51-year-old Gabriel Wortman, who worked as a denturist, appeared at one stage to have been wearing part of a police uniform.
