Gardaí investigating the disappearance of Trevor Deely have completed their search operation at the site in Chapelizod, Dublin 10.
According to Gardai, nothing that furthers the search for Trevor was located during the search.
In a statement, an Garda Síochána said they wish to thank the public for their patience during the operation.
The site remains closed to the public.
The search of a three acre woodland site began just under two months ago, and a gun was found during the operation.
The 22-year-old disappeared after his office Christmas party in Dublin in the year 2000.
The last known sighting of Trevor Deely was captured by a CCTV camera at the junction of Haddington Road and Baggot Street on the night of December 8 at around 4am.
The CCTV footage shows a man dressed all in black following him.
It has not been confirmed if the gun is linked to Mr Deely's disappearance.
