Human remains discovered in the Republic in July were those of a man believed to have been abducted and murdered by the IRA in 1981, it has been confirmed.
Charlie Armstrong, 57, from south Armagh, went missing on his way to Mass.
The Independent Commission for the Location of Victims' Remains (ICLVR) has received the results of the DNA examination following the find at Colgagh, Co Monaghan.
A spokesman said: "The results positively indicate that the remains are those of Mr Charlie Armstrong."
Dublin coroner Dr Brian Farrell has authorised the release of the remains to the dead man's family.
Mr Armstrong's family believe he was abducted and murdered by the IRA.
He is one of the so-called "Disappeared" - 14 men and women abducted and killed by republican paramilitaries at the height of the violence in Northern Ireland.
For several months in 2008, a team of experts concentrated on an area of bog and gorse at Inniskeen in a search just a couple of miles from the Armstrong family home in Crossmaglen.
The commission was prompted to act that year by an anonymous map, sent to the family, which claimed he had been buried there.
It was the second map the family had received. The first showed a slightly different location.
