Gardaí investigating the disappearance of Trevor Deely will start excavating a search site in Chapelizod in this morning.
It's after receiving new information relating to the missing Naas man, who was 22 when he disappeared 17 years ago.
Detectives spent the weekend clearing overgrowth and mapping areas of woodland by the banks of the Liffey.
Stephen Breen, Crime Editor of the Irish Sun, says they've brought in a forensic archaeologist to help:
"She is someone with a background in this type of investigation, who has the expertise to assist gardai as part of their search."
Gardai are acting on new information that has come to light. However it hasn't been produced as a result of a renewed appeal for information in April this year. Instead it's understood to have been gleaned from an informant.
Papers today report detectives are acting on intelligence suggesting Trevor was murdered by a known Crumlin criminal, possibly as a result of a chance interaction.
Conor Lally of The Irish Times says the investigation team is acting on credible information about the exact spot where Trevor is buried.
The April appeal was launched after digitally enhanced CCTV footage showed a man dressed in black acting suspiciously outside the rear entrance of Bank of Ireland where Trevor worked on on Wilton Terrace. He was seen between 3am and 3:34am, prior to Trevor Deely arriving.
At 3:34am, just moments before Trevor approaches his place of work, the footage shows this man stepping out onto the footpath and following Trevor to the back gate of Bank of Ireland before chatting with him briefly at 3:35am.
Trevor was last captured on video passing the Bank of Ireland ATM machine on Haddington Road at about 4.14am on the 8th of December 2000.
Gardaí believe that the man acting suspiciously outside of Trevor’s workplace is the same man that is seen passing the Bank of Ireland ATM on Haddington Road at 4.14.am, just moments after Trevor Deely.
