Days after the killing of a prison officer, Stephen Gault laid a floral tribute to father, Sammy Gault, a retired Royal Ulster Constabulary officer, at a service remembering the Enniskillen Poppy Day bomb attack.
Eleven people died in the blast. A twelfth death was recorded later.
Mr Gault turned 18 a few days before the bombing. He said yesterday: "It was one of the darkest days of the Troubles. I want people to remember the agony and torment the families have been through."
