American Taboo aka Lost in Paradise Forty Eight Hours : Season 18 Episode 5

In late 1975, a young Peace Corps volunteer named Deb Gardner arrived in Tonga, and so began a story of adventure and love and ultimately, of murder. Correspondent Susan Spencer talked to many people who still remembered the night of Oct. 14, 1976, when Gardner was stabbed to death in her hut. Those who weren't around then have heard the stories told and retold.
