Unfortunately the story isn’t more widely known and hasn’t yet been folded into the general consciousness but is known by those who read the best selling book by David Gann called Killer of the Flower Moon (the Osage Murders the birth of the FBI). He’s an excellent author and does brilliant research. Ive long been a podcast listener and heard him talk about the story in an interview he did here in 2018:

This was riveting (if slightly dry) listen because grew up in Texas and never heard about these murders or about the calculating evil betrayal their spouses engaged in. Further, I may have a little Indian blood in my family mix on my dads side who lived in OK then (we don’t think tied to Osage but yet to be determined which tribe exactly) and hearing the story further piqued my interest in genealogy and early US history to figure out how we all got here today, why are there so few Indians left (beyond obvious and known reasons) and facts of the systematic breaking of treaties with native indian tribes was a large part of it.

When treaties and theft didn’t work the Osage murderers just outright slaughtered their Indian wives and family. All for oil and money tied to the then new industry.

Sad thing about the Gann book is it was started in 2014 but came out in 2017 just before the huge increase of True Crime podcasts so it was somewhat too early to the listening party.

The upcoming film adaptation might get more traction:

“The book was acquired for film adaptation by director Martin Scorsese in 2017. Starring Leonardo DiCaprio, Robert De Niro, Jesse Plemons, and Lily Gladstone, the film is set to be released theatrically by Paramount Pictures and stream on Apple TV+ in 2023.”
