As searches continue on the Kildare Wicklow border into the disappearance and murder of Jo Jo Dullard, Gardai say they are determined to provide answers.
They sealed off an area of land a week ago, as part of their search for information on the 21-year-old, who was last seen in November 1995 in Moone.
Superintendent Paul Burke says they are keeping her family informed about the search.
He said her family "continue to suffer".
