After the Good Friday Agreement, the Irish and British Governments set up the Independent Commission for the Recovery of Victims Remains.
Its aim was to locate the remains of those killed by republican paramilitaries and secretly buried during The Troubles – people commonly referred to as The Disappeared.
The commission has a confidential telephone number and post box, and the information it receives can only be used to help recover the dead. In many of the ten cases where remains have been found, republicans and/or others used these facilities to provide crucial information.
Earlier this year, Minister for Justice Frances Fitzgerald confirmed the Government's ongoing commitment to help fund the work.
She said: "Out of human decency, I appeal to anyone who can help bring an end to this suffering to do so."
Statement by Minister for Justice, Frances Fitzgerald, confirming the Government's ongoing support for efforts to locate the remains of the so-called Disappeared:
"The Government remains as strongly committed now to the humanitarian aim of locating the victims for their families as at the outset of the process, and I will continue to support the ongoing efforts to locate those victims who have yet to be found.
I encourage anyone with information that could help to locate those still missing to give that information, in full confidence, to the ICLVR without delay.
The families of the missing victims have suffered enough. Out of common human decency, I appeal to anyone who can help bring an end to that suffering to do so."
Of the six people still missing, five are thought to be buried south of the Irish border and a sixth, Seamus Ruddy, is believed to be buried in a forest in France.
The INLA admitted killing Seamus Ruddy. The five other deaths are attributed to the IRA.
The remaining ‘Disappeared’
In February 2010 Joe Lynskey was added to the official list of The Disappeared. He was a member of the IRA. He went missing from his west Belfast home during the summer of 1972; his body has never been recovered. Joseph Lynskey was a former Cistercian monk from the Beechmount area of west Belfast. A new search for his remains was carried out over the summer.
Columba McVeigh disappeared on 1 November 1975 and his body has never been recovered. He was from Donaghmore, Co Tyrone. He had been working as a painter in Dublin and had only returned to Northern Ireland a few days earlier. Although extensive searches, based on information received, have been carried out at Braggan Bog in Co Monaghan, his remains were not found.
Robert Nairac disappeared in 1977. He was an officer with the British Army's Grenadier Guards on a tour of duty in Northern Ireland when he went missing. It is thought he was on an intelligence-gathering operation and was singing republican songs in a pub in South Armagh on the night of his abduction. He was 29-years-old. A man was convicted of his murder in 1977 and served a prison sentence. Captain Nairac received a posthumous George Cross.
Seamus Ruddy disappeared in Paris on 9 May 1985. A native of Newry, he had links to the INLA and its political wing, the IRSP. He was involved in negotiations on behalf of INLA prisoners in the MAZE during the 1981 Hunger Strikes and helped to carry the coffin of hunger striker, Michael Devine, at his funeral in Derry. In May 1985 he was working as an English teacher in Paris. It is thought he got into a dispute with INLA members who were attempting to procure weapons in France. In December 1995 the INLA admitted responsibility for his death. In February 1999 information emerged to suggest that his body was buried in Rouen, France, but despite searches having been carried out his remains have not yet been recovered.
It is believed that information provided by republicans and/or others assisted in eight of the ten cases where remains were recovered. With Jean Mc Conville (2003) and Eugene Simons (1984), the discoveries were made by chance.
Kevin McKee and Seamus Wright disappeared on 2 October 1972. The two of them were from Belfast - Seamus Wright worked as an asphalt layer. He was aged 25 and married when he went missing. It is thought they were both members of the IRA and were suspected of passing on information to the security forces. Their remains were discovered on a farm near Coghalstown, Co Meath.
Brendan Megraw was 23-years-old when he was taken from his flat in Twinbrook, west Belfast by the IRA in April 1978. His wife was expecting their first child at the time. His remains were recovered at Oristown Bog, near Kells in Co Meath in autumn 2014.
