Why is this week a particularly difficult one for the family of Trevor Deely?
Because it marks the 20th anniversary of arguably the most notable missing person case in recent Irish history.
Last Monday, friends and relatives of Trevor gathered near Haddington Road in Dublin, where he was last seen, and launched another appeal for anyone with information to come forward. He is the baby of our family and we have spent the last two decades doing all we can to find him, said his sister Michele. The pain of not knowing where Trevor is is getting more and more difficult to bear. Please help us.
