The Story

Michael Rockefeller, 23-year-old son of New York Governor Nelson Rockefeller, disappeared off the southern coast of Dutch New Guinea in November 1961. His catamaran had overturned; he swam toward shore while a companion was rescued. Dutch and local searches found no body. Rumors persist of drowning, shark attack, or ritual killing by Asmat villagers.
