Gardaí have confirmed that skeletal remains discovered at Killakee Mountain in Dublin on Friday were those of a woman.
The remains were discovered by a woman out walking in a wooded area.
Detectives are awaiting the results of DNA testing and dental records following a post-mortem examination carried out today.
They are examining the possibility that the body could be that of one of 20 women who have been reported missing.
They believe the woman may have been in her 30s.
Gardai are working with officers from the Serious Crime Review Team, and using the services of a forensic anthropologist to try to establish how long the body lay undiscovered.
Forensic examinations have been continuing at the scene.
A pair of runners found close to where the remains were found is among the items being examined.
Detectives are liaising with gardaí from Operation Trace, an inquiry into the disappearance of six young women in Leinster during the 1990s.
However, it is also possible the woman died more recently.
Gardaí hope to have some test results by early next week.
