The death of a Co Armagh teenager who was struck by a train has affected many lives, mourners heard yesterday.
Hundreds of people who attended Requiem Mass for 19-year-old Shea Martin in St Peter's Church in Lurgan were told they may never know why he died.
Fr Brian Fitzpatrick described the "unexpected turn of events" as "a great injustice".
He said: "It is what it is. And we know that we may never get a satisfactory answer as to why, but that doesn't stop us asking."
The teenager was struck by the train in the town at 6.30am on Monday and died at the scene.
The tragedy happened just three days before he would have turned 20.
Fr Fitzpatrick said the sense of disbelief that Shea's devastated parents were feeling will carry them through until they can begin to contemplate the reality of life without their beloved son.
He added: "Everyone is moved with compassion for Shea's dad Liam and mum Tracey.
"He was a good brother to Liam and Maria, and he was a good uncle, too, once he found the confidence to hold his tiny little nephew."
The clergyman said the "quiet lad with a good sense of humour" was a "treasure" to his family and to his tight circle of friends.
"He put smiles on so many faces," he said.
"All his parents can do now is express a profound act of faith by asking God to keep their son safe until they see him again.
Mourners heard that Shea had a passion for computer games and was in the top 250 gamers in Europe.
"He had an amazing flare for games, especially Destiny, and was among the very best in the world," Fr Fitzpatrick said.
"People even came to him for professional advice - his loss has been felt and noted online."
However, Fr Fitzpatrick said it was Shea's family who will feel the most pain.
"The yearning to say 'Shea, I love you' is what hurts so much," he said.
"They are in a living nightmare but are wrapped in love."
The priest added that the teenager's battle with anxiety caused him "turmoil", and would often keep him awake at night.
"But he is at peace now," he said.
He also prayed for the train driver, and praised the emergency crews who tried to save the teenager.
Fr Fitzpatrick told mourners: "At the end of the day, you switch a computer off and you have to walk away.
"You find yourself back in this world, where real destiny, life and fulfilment are to be found.
"May Shea find that now as he rests in everlasting peace."
