In the 1920s, the Osage were considered the richest people per capita in the world, thanks to oil wells on their land. But in the early 1920s, about two dozen tribal members were killed mysteriously. 

Author David Grann delves into those deaths and the conspiracy behind them in his book “Killers of the Flower Moon: The Osage Murders and the Birth of the F.B.I.

Host Geoff Norcross spoke with Grann about the Osage murders, how the investigation into the deaths shaped the early years of the FBI and why we’re so fascinated by true crime stories. 

This conversation was recorded in front of an audience at First Congregational United Church of Christ during Wordstock: Portland’s Book’s Festival
