A group seeking clues to the fate of American aviator Amelia Earhart is ending its latest search of a remote South Pacific island with "no smoking gun" but not entirely empty-handed.
Leader Ric Gillespie says the 100 or so artefacts collected at Nikumaroro (part of Kiribati) offer possible links to Earhart and her navigator, who vanished over the Pacific during a round-the-world flight in July 1937.
