An adored primary school teacher, a respected policewoman and a kind nurse are among the tragic victims of Canada's worst mass killing in over 30 years.
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.
The Royal Canadian Mounted Police said the gunman, 51-year-old Gabriel Wortman, appeared at one stage to have been wearing part of a police uniform and even disguised his car to look like a police cruiser.
Police added they had ended the threat posed by Wortman, who was dead, but would not confirm a report by the CTV network that the RCMP had shot him.
