My brother was 'the kindest human being I have ever met'published at 09:55 Greenwich Mean Time 29 January
One of those who will be commemorated this morning is Alan Radford, who was 16 when he was killed.
A pupil at Omagh High School, Alan had been in the town with his mum to open a bank account.
He was due to start training as a chef the following month.
His sister, Claire Hayes, (pictured in 2023) will speak at the hearing. She was 15 when her brother was murdered.
Speaking on BBC News NI's Good Morning Ulster this morning, Claire says Alan was "the most innocent, purest, kindest human being I have ever met in my life".
"Everything Alan did was for the purpose of others, to try to make the life of somebody just that wee bit brighter, even if it was just by giving them a smile, making a comment."
He helped neighbours, babysat and cut grass - even though he had "the worst hayfever in the world".
She adds: "I remember him coming in with his eyes closed together, swollen up, sneezing, and I'd be like: 'Alan, what are you doing out cutting people's grass?' And he'd go: 'They need help, Claire.'
"That's just the person he was. He had no ounce of malice in him, no hatred, nothing."
