Mystery donation to find 'Disappeared' might be a game changer

Available for over a year

The anonymous donation of $60,000 (£47,191) has been given to the independent UK charity Crimestoppers. In spite of numerous searches, three of 16 victims known as the Disappeared - Joe Lynskey, Columba McVeigh and Captain Robert Nairac - have not been found. Geoff Knupfer, who is lead investigator at the Independent Commission for the Location of Victims' Remains, tells Karen Patterson that the donation might prove to be a game changer .
