Newry man Seamus Ruddy was working as a teacher in France when he was killed and secretly buried by the republican paramilitary group, the INLA, in May 1985.On the 29th anniversary of his death, his sister Anne Morgan has appealed for information to find his body.She believes he was buried in a forest in Rouen.The most recent dig for Seamus's remains took place in 2008 and Anne is confident that any information would lead to further searches.Anne said her brother had been a member of the Irish Republican Socialist Party but had resigned before leaving for France.She said that he was most likely targeted due to internal feuding in republican circles.She explained: "Seamus was living his life in Paris, away from all the troubles here in the north of Ireland and by distancing himself from that he thought that he was safe, but in fact he was not safe."Anne also claimed that she has met a man she alleges is responsible for her brother's murder.Describing the moment, she said: "He didn't show any sign of remorse, or anything else."When you're faced with your brother's killer, it's not an easy task but we still have to follow this through."We have to put pressure on those men that have the information, to come forward and give it confidentially."Sixteen people were abducted, murdered and buried in secret, mostly by the IRA during the Troubles. They became known as the Disappeared. Seven families, including Mr Ruddy's family are still waiting to bury their loved ones.On 30 August last year, the Day of the Disappeared, actor Jimmy Nesbitt joined in the families' calls for information.Anne is part of the group of relatives who meet at the WAVE trauma group in Belfast.She added: "Our loved ones are disappeared and we are unable to give them a Christian burial and that's what unites us."There is a grave waiting for Seamus in Newry, and his name is on the headstone. We hope that one day, one of those men who killed our Seamus will be brave enough to come forward to the Independent Commission for the Location of Victims' Remains and to give them the information that's needed."There will be no prosecution, we will not be going to the courts concerning our Seamus's death. We have given up our right to justice in the courts only to have his body returned to us and that we can give him a Christian burial."
