Gardaí have launched a murder inquiry after the discovery this morning of human remains on open ground near the Sundrive Road in Crumlin.
Gardaí were conducting a search for a missing 22-year-old man missing from the area since last September.
A preliminary examination of the scene has been carried out by the State Pathologist, Dr John Harbinson.
The discovery is the second such find in two weeks. The remains of another man were uncovered in a neighbouring area, also buried in a shallow grave.
The remains were uncovered when detectives investigating the drugs-related disappearance of a 17-year-old from Ballyfermot in the west of the city received an anonymous tip-off.
The youth vanished in January 1999 and is thought to have been killed and buried in the Clondalkin area.
His family believe he was abducted over a heroin debt of several thousand pounds.
Both bodies had been there for some time, and police said it could be a number of weeks before the identity of either man was finally confirmed.
