Captain Harry "The Nose" Jongen, who earned his nickname by scouring Second World War battlefields for fallen soldiers, will track human remains near the south-western town of Orahovac.
It will not be his first trip to the Balkans. In 1993, the United Nations asked him to travel to the region to assist the war-crimes tribunal in investigating earlier atrocities. He discovered a grave containing 19 bodies north of Zagreb.
In Belgium, he helped locate bodies of the murder victims of the paedophile Marc Dutroux in 1996. Captain Jongen works by sticking a steel rod into the ground and then sniffing the end of it.
