The 22-year-old went missing on December 8th back in 2000
The family of missing man Trevor Deely are renewing their appeal to find out what happened to him.
He went missing on December 8th back in the year 2000, after a Christmas party in the Leeson Street area of Dublin.
At around 3.00am he went back to this office at Lesson Street Bridge, where he talked to a co-worker who was on night duty.
He picked up an umbrella and headed back out - where he went across Baggot Street Bridge, heading down along Haddington Road.
A CCTV camera picked up his image and that is the last known sighting of him.
Trevor was 22-years-old when he went missing. He is originally from Naas but was living in the Dublin area.
He was last seen at Haddington Road in the city, wearing a yellow and brown shirt and beige cord trousers.
He is described at 6ft in height, of slim build with short red/blonde hair and green eyes.
His father, Michael Deely, told Newstalk Lunchtime they have had no further information about him.
"Absolutely nothing - that's what makes it so difficult, that we're getting no information at all coming forward ever since that" he said.
He says several reported sightings have turned out to be nothing. But he also believes that Trevor could still be alive.
"We have absolutely no concrete information that anything sinister (happened)".
