A search in Co Meath for the remains of a man who was abducted and murdered by the IRA in 1972 has ended unsuccessfully.
Joe Lynskey, a former Cistercian monk who later joined the IRA, was kidnapped in west Belfast in August 1972.
He became known as one of the so-called Disappeared - 16 people abducted and secretly buried by republicans in the 1970s and 1980s.
Searches have been carried out at Oristown in Co Meath since early March.
It is the same area where the remains of Brendan Megraw were found in 2014.
The remains of two other Disappeared men - Kevin McKee and Seamus Wright - were found during a previous search for Mr Lynskey's remains at nearby Coghalstown in 2015.
A senior investigator with the Independent Commission for the Location of Victims' Remains said the result of the search was "deeply disappointing."
Jon Hill said they had been working on information which "was given in good faith and warranted further investigation."
He also appealed for fresh information on the case, following the two searches this year and in 2015.
"There is a cast iron guarantee, enshrined in international legislation that the information we receive and the identity of those providing it will never be revealed to anyone else," he said.
Mr Lynskey's niece, Maria Lynskey, thanked the ICLVR for their worked and also called for more information.
Of the 16 Disappeared, the remains of 13 have been recovered.
The remaining three are Mr Lynskey, Columba McVeigh, who was kidnapped in 1975, and British soldier Captain Robert Nairac, taken in south Armagh and killed by the IRA in 1977.
