Excavation work is due to start in west Dublin this morning as part of the investigation into the disappearance of Trevor Deely.
Mr Deely went missing in December 2000 – but new information has led Gardaí to a site in Chapelizod.
Gardaí received information that Trevor Deely may have been shot and buried at the site by a known criminal.
Railings around the site have been covered in black plastic sheeting and a number of detectives have been coming and going from the site this morning.
Gardaí believe their new information may be a significant breakthrough in the case
