 who had committed these crimes against members of the Osage Nation, systematically killing them for their oil money, who had committed these crimes with a few henchmen, because that was the theory laid out by the FBI at the time. But over time, I kept meeting with members of the Osage Nation, and a lot of the Osage elders kept telling me about other suspicious deaths in their family that weren't ever investigated and weren't part of the FBI case, and that had no links to this killer.
