In October 1993, loyalist gunmen opened fire in a bar in Greysteel, County Londonderry, killing eight people.
For the first time since the attack, the son of one of the victims has spoken about the effect her murder had on her family.
Martin Duddy told BBC Newsline's Kieron Tourish that his mother, Moira, was loving, caring and at the centre of the family.
