Columba McVeigh from Donaghmore County Tyrone was 19 years old when he was murdered and secretly buried by the IRA in 1975.
A number of searches under the auspices of the Independent Commision for the location of victims has been carried out in the area of North Monaghan known as Bragan bog yielding nothing.
