OKLAHOMA CITY (AP) — The latest search for the remains of 1921 Tulsa Race Massacre victims has ended with three more sets containing gunshot wounds, investigators said.

The three are among 11 sets of remains exhumed during the latest excavation in Oaklawn Cemetery, state archaeologist Kary Stackelbeck said Friday.

“Two of those gunshot victims display evidence of munitions from two different weapons,” Stackelbeck said. “The third individual who is a gunshot victim also displays evidence of burning.”

Stories like this underscore the importance of reading history, because (at least here in Missouri) I was never taught about the Tulsa Massacre and didn’t learn about it until I read about it myself.

Other things you may want to read about that you may have never heard of: The Battle of Blair Mountain, Haymarket Square, or the Great Rail Strike of 1877.
