Senior RCMP officers in Nova Scotia say "in excess" of 10 citizens, including veteran officer Const. Heidi Stevenson, have died in a mass shooting. Chief Sup. Chris Leather said Sunday the total number of dead and injured could rise as they examine crime scenes, including at the small village of Portapique. The suspect, Gabriel Wortman, was killed by police at an Enfield, N.S., gas station later in the day.
