DNA tests are to be carried out to establish if human remains found in Co Wicklow are those of a missing Dublin man.
Paul Byrne, 21, was last seen in Kilmartin Green in Tallaght in July of last year. His family visited the site over the weekend.
A skull and other remains were recovered during searches at Ballyfolan in west Wicklow last Thursday.
However, gardaí say they cannot yet establish a link between the discoveries and Mr Byrne's disappearance.
They hope the tests will lead to formal identification in the coming days.
