Our mission in life is to know precisely what happened to Trevor. You can’t give up hope, you have to keep that up

this. There was one person on IT duty that night. Trevor had a cup of coffee with him in the canteen, checked his emails, and then picked up his umbrella — a large, blue ACC golf umbrella — and he made his way home to his apartment. Most of his journey was caught on CCTV.

When he was on Haddington Road, he was seen quite clearly walking along with his umbrella. There was a big puddle of water and he avoided it. That is the last sighting of Trevor. There was a huge investigation and the gardai are very conscious that it's ongoing.

There have been thousands of posters with Trevor's face staring down and extensive searches with huge support from our friends and family. But since then there has never been anything positive in terms of substantial evidence. Nothing was ever found, not even his umbrella or his clothing.

There's not a day or hour goes by that you can get away from it. It's always there. But the thing to do is to try to live as normal a life as possible. That's the difficult part, the day-to-day living. The one good thing that has happened is that we have eight grandchildren now.

Our mission in life is to know precisely what happened to Trevor. We're out there doing our work, keeping his name out there. You can't give up hope. You have to keep that up, otherwise you wouldn't get up in the morning.

We're a Catholic family and our faith never altered. In a way, it kept us together and gave us absolute strength. Our parish priest, Fr John, has been our best friend since. He didn't know Trevor because he wasn't long in the town, but he’s been our rock — so sensitive and understanding. Every year, he organises a prayer service for Trevor on December 6. I see friends from his group of pals there.

The first Christmas without Trevor was probably the worst, but they are all difficult. But life has to go on. The way I rationalise it is that Trevor was a man who enjoyed himself, he always went to parties and he had a lovely, instant smile. In the very early days I felt guilty if I found myself laughing at something. It was as if you were letting him down, but now I see it as important. I think we owe it to Trevor to be there for him and to keep ourselves as well as we can for him.

As I lay my head on the pillow at night, I always pray to Trevor.
