'Our precious mum was among the dead'published at 15:58 Greenwich Mean Time 4 February
On 15 August 1998, Mark was a long distance lorry driver and had returned home and was washing his lorry when he saw his other off as she headed to Omagh for shopping.
His father then heard about the bomb and had a bad feeling.
Mark says he will always remember his dad going into Omagh and desperately searching for his mum.
At the time, Mark had arranged for his sister Mandy to be picked up from Dublin and be brought to the leisure centre in Omagh.
"It was not until the next day that we got confirmation that our precious mum was among the dead," the statement reads.
