In the early 20th century, tribal members of the Osage Nation in Oklahoma became extremely wealthy after discovering oil underneath their reservation. Then, dozens of Osage members started turning up murdered in a vast conspiracy meant to redirect their wealth into the hands of white men.
In the recent book Killers of the Flower Moon, author David Grann explores this chapter in American history. Grann visited the University of Wyoming as a guest lecturer, and Wyoming Public Radio's Caroline Ballard spoke with him about how he first became interested in the Osage Indian Murders and their legacy.
