The lead forensic scientist and investigator for the Independent Commission for the Location of Victims' Remains is to retire this week.
Geoff Knupfer, who has been in the role since 2005, said it has been "an honour" to be so closely involved in humanitarian investigations.
The ICLVR was set up in 1999 following the Good Friday Agreement to locate and recover the remains of those abducted, murdered and secretly buried during the Troubles - known as the "Disappeared". To date the remains of 13 Disappeared have been recovered out of a total of 17.
