The sister of a man murdered and secretly buried by the IRA almost 50 years ago has vowed to keep searching for him and others like him.

Dympna Kerr’s brother, Columba McVeigh, was one of the 17 murder victims known as The Missing.

Four of those listed by the commission created to find them are still missing.

Mrs Kerr and other family members took part in an annual walk in Stormont to remember them.

“We will come here every year until we find them,” he told BBC News NI.

“It may not be me who comes. I may be running out of time.”

“But we have children who will follow in our footsteps and there will be families who will come here until every last member of that list has been found.”

Other victims who have not yet been located are Joe Lynskey, Seamus McGuire and army officer Captain Robert Nairac.

The search for Captain Nairac’s remains at Faughart, near Dundalk in the Republic of Ireland, ended last month without success.

McVeigh, from Donaghmore, County Tyrone, was 19 when she disappeared in 1975.

Multiple searches have been carried out over the years, concentrating on Bragan Bog near Emyvale in County Monaghan.

The searches have been carried out by the Independent Commission for the Location of Victims’ Remains (ICLVR).

Mrs Kerr appealed for anyone with information about the whereabouts of her brother and the others to come forward.

“Someone has that information,” he said.

“They might think it’s irrelevant or that someone else will tell them. It’s not up to anyone, and I mean anyone with the slightest bit of information, to decide whether it’s relevant or not; bring it to the committee.”

“Let’s let the commission make that decision. Because I’m telling you now, if the commission gets the information, they will find it.”

Family members said a prayer and walked to the steps of the parliament buildings, where they laid a black wreath with five white lilies.

Four of the lilies represented each of the remaining four of The Missing, and one was for the missing Lisa Dorrian.

It has been almost 20 years since she was last seen at a party at a caravan park in Ballyhalbert, County Down. Police believe she was murdered.

No one has ever been convicted and, despite many searches by land and sea, his body has never been found.

His father, John Dorrian, told BBC News NI that joining other families brought him some comfort.

“Coming here on this walk helps us meet other people who are in the same circumstances and we try to support each other,” he said.

“As a family, we feel sorry for the people who also have missing people because we know how they feel. I know these people have been missing since the ’70s. It must be terrible.”

Anne Morgan, whose brother Seamus Ruddy was one of the missing and whose remains were recovered in 2017, also attended the walk.

“We have discovered that being together has helped us be heard,” he said.

The walk is organized by Wave Trauma Centre, which has supported families of the missing since the mid-1990s.

The organisation’s chief executive, Dr Sandra Peake, said: “One of the evil aims of those behind missing people was to literally wipe every trace of them off the face of the earth as if they had never existed.

“The sheer inhumanity is shocking.

“Until all the missing are home, the families will not rest or remain silent.”
