Families of those secretly killed and buried by paramilitaries during the Troubles took part in their annual silent walk at Stormont.

Investigators are keeping an ‘open mind’, pending the results of tests to determine whether the remains belong to IRA murder victim, Joe Lynskey.

The remains also do not belong to any member of the family who own the grave plot in Annyalla, Co Monaghan, investigators have said.

Mr Lynskey, a former monk from Belfast who later joined the IRA, was abducted, murdered and secretly buried by the IRA in 1972.
