The flag-draped coffin of Lionel Desmond is carried into St. Peter's Church in Tracadie, N.S. on Wednesday, Jan. 11, 2017. It was almost three years ago that Desmond - a deeply disturbed Afghan war veteran diagnosed with PTSD - killed his mother, wife and young daughter before taking his own life in the family's rural Nova Scotia home.THE CANADIAN PRESS/Andrew Vaughan
