Gardai are appealing for information on Trevor Deely, 20 years after the Kildare man was last seen.
The 22 year old attended his Christmas party on December 7th 2000 and never returned home.
He was last seen in the Haddington Road area of Dublin just after 4am on December 8th.
CCTV
Gardai say they want to identify a man in dark or black clothing pictured in CCTV footage talking to Trevor at a gate on Wilton Terrace at the rear entrance to his work place.
Trevor's father Michael says he just wants his son back.
Michael Deely has made an appeal on the anniversary of the disappearance of Trevor.
A reward of €100,000 has been put forward for information on his whereabouts.
Speaking at Pearse Street Garda Station Inspector Katherina Joyce said: "After spending the night socialising in Dublin City without incident 22-year-old Trevor Deely was last seen on CCTV passing the Bank of Ireland ATM on Haddington Road, at approximately 4:14 a.m. on the 8th December 2000.
"Our investigation continues to focus on trying to establish the identity of a man dressed in dark / black clothing pictured in CCTV footage talking to Trevor at a gate on Wilton Terrace at the rear entrance to Trevor’s work place. We believe the same man can later be seen walking a short distance behind Trevor in CCTV footage at the Bank of Ireland ATM on Haddington Road, he has never been identified.
"This was the last known sighting of Trevor Deely and we believe the man pictured in this CCTV may have vital information that help us to solve this case.
"We would ask this man or anyone who can identify him to come forward.
"We believe the answers we require may be found in the community and at this time we are appealing to those who, for whatever reason, have not been in a position to come forward to date to reconsider contacting us."
Pain
Speaking on behalf of the Deely family Trevor’s sister Michele said: "We are desperate to find Trevor. It is hard to believe we are now 20 years without him. He is the ‘baby’ of our family and we have spent the last two decades doing all we can to find him. But we are still stuck in the same place of not knowing anything beyond his last confirmed sighting at the top of Haddington Road.
"The pain of not knowing where Trevor is, is getting more and more difficult to bear. Please help us. All we want to know is, where is Trevor?"
