Meanwhile, Trevor O’Neill’s father described his son’s murder in Spain last week as “senseless”.
Vinnie O’Neill spoke of his heartache at the weekend as he stared at the flowers and county football jerseys draped across the gates of his son’s home in Crumlin.
He said that the only consolation he had was that if there was a heaven, he believed that where his son was now.
“He was too good; he was too good. So he can’t go anywhere else,” he said.
“He was one of the best human beings I ever knew and just look around at the flowers left by all the neighbours.”
Gardaí had told him it was a case of mistaken identity, he said. “Trevor wouldn’t know any of those people,” he added.
“All Trevor was into was work and the kids. That was his life,” said Mr O’Neill in an interview published in a Sunday newspaper.
Mr O’Neill described his son’s killing in Majorca on Wednesday night as being “senseless”.
The father of three was shot dead while on holidays with his wife Suzanne and three children in Costa de la Cama in a case of mistaken identity.
He was shot three times in the back after being mistaken for a member of the Hutch family.
“He was the greatest young fella, and not because he was my son; he was the greatest young fella that God ever gave breath to. He was just a super human being and all I can be thankful for is 40 years of him.”
Trevor O’Neill worked as an inspector in Dublin City Council’s drainage services division where he is sadly missed by his colleagues who all thought highly of him.
Described as an energetic worker, he had a keen interest in flood relief. “He was very outgoing and very well thought of by all who worked with him,” a colleague said yesterday.
