Searches for information about the murders of Deirdre Jacob and Jo Jo Dullard may continue for some time.
Excavators were brought into a quarry between Blessington and Baltinglass yesterday to search for clues about the killings of the women in the 1990's.
Gardaí say they began the operation on foot of new information.
It's the first time there has been any suggested link between the murders of Jo Jo and Deirdre who disappeared 3 years apart in Co. Kildare.
