The wife of a Co Armagh man the IRA insists it did not 'disappear' yesterday (Thursday) said she was grateful for any help to find her husband's remains.
Kathleen Armstrong was speaking after Sinn Féin president Gerry Adams said his party was continuing to work "to secure the return of the remains of those who were killed and secretly buried by the IRA".
Mr Adams said he met with the family of Charlie Armstrong, ahead of the 25th anniversary of his disappearance on August 16 1981.
Mr Armstrong, a father-of-five, was 55 when he disappeared after leaving his Crossmaglen home to give a pensioner a lift to Mass.
His car, which bore traces of gun residue, was later found outside a cinema in Dundalk, Co Louth.
The IRA denied responsibility for Mr Armstrong's disappearance and that of 24-year-old Gerard Evans, also from Crossmaglen, who was last seen in 1979.
Mrs Armstrong said she would welcome "anyone's help" to find her husband's remains and said she did not know who was responsible.
"I never knew who was behind it and I still don't know. We are looking to everybody for help," she said.
"I can just remember his disappearance as fresh in my mind as the day it happened. My family stood by me only for that I don't know what I would have done."
The couple had three sons, two daughters and 14 grandchildren, four of whom were born before Mr Armstrong disappeared.
She said she and the Evans family derived comfort from each other.
Neither Mr Armstrong nor Mr Evans were included on the IRA's list of nine disappeared, five of whose remains have not been found.
Searches for Mr Armstrong's remains in north Monaghan in 2002 and 2003 were unsuccessful.
Mr Adams said yesterday the party was "working on" the cases of Mr Evans and Mr Armstrong and renewed an appeal for information.
He said the 25 years since Mr Armstrong's disappearance had been a "long, difficult and emotional time for his family".
"Their sole interest is in securing the return of Mr Armstrong's remains. Mrs Armstrong wants to give her husband a proper funeral and she and her family have an absolute right to do this," he said.
Mr Adams said people could speak to him "in complete confidence" if they knew where Mr Armstrong was buried.
Last week the British and Irish governments announced measures for the recovery of the bodies of the remaining five disappeared who the IRA has claimed to have kidnapped, murdered and secretly buried.
Auxiliary Bishop of Armagh Gerard Clifford will celebrate Mass in Crossmaglen tomorrow night in memory of Mr Evans and Mr Armstrong.
