Gardaí have renewed their appeal for missing Trevor Deely (22) on the 20th anniversary since when he was last seen.
Originally from Naas in Co Kildare, Mr Deely went missing after an office Christmas party on December 7, 2000.
CCTV footage showed that he went from a bar back to the office to collect some of his things and was last seen on CCTV, passing the Bank of Ireland ATM on Haddington Road, at approximately 4.14am on December 8, 2000.
Gardaí are eager to speak to a man wearing dark clothes, who was spotted in the CCTV talking to Mr Deely at a gate on Wilton Terrace at the rear entrance to Mr Deely’s work place.
It is believed that the man can be seen walking a short distance behind him in CCTV footage at the Bank of Ireland ATM on Haddington Road, but despite numerous appeals, the man has never come forward or been identified.
Speaking this month, Mr Deely’s father Michael said that he just wants his son to come home.
“You just can never get away from it, no matter where you drive down the country or walk out to the town of Naas, it’s the same thing, there’s always something to remind you of Trevor.
“I would ask anybody with information about Trevor, or about his whereabouts, to please let us know. The appeal is to just find my son, I want him back.”
At the time of his disappearance, his father Michael made a heartbreaking televised appeal, where he recalled his son telling him about a recent trip away and how he had promised him that they would discuss it in more detail over Christmas.
"He said, ‘Listen, it was a marvellous trip, a trip of a lifetime’.
"It’s one of my biggest regrets that we didn’t have that talk,” he said emotionally.
Mr Deely’s case remains under active investigation by An Garda Siochana.
“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,” said Garda Station Inspector Katherina Joyce, speaking at Pearse Street garda station.
“We would ask this man or anyone who can identify him to come forward.”
She appealed to people who may not have been previously in a position to come forward with information.
“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,” Inspector Joyce added.
A Crimestoppers reward of €100,000 is still active and available to anyone who comes forward with information that could assist in locating Mr Deely or provides significant progress in the case.
“An Garda Síochána appeals to anyone with any information, no matter how small or insignificant they may believe it to be, to contact the incident room at Pearse Street Garda Station on 01 6669000, Crimestoppers 1800 250 025, or any Garda station,” said a garda spokesperson.
