In Tulsa, Oklahoma, investigators searching for victims of the 1921 Greenwood massacre have discovered another 17 bodies buried in a mass grave in a local cemetery. It is believed 300 African Americans were killed and 1,000 injured when a white mob descended upon and destroyed the Black neighborhood known as “Black Wall Street.” None of the white supremacists were ever arrested in connection with the violence, which included aerial bombardment with dynamite and incendiaries on the 35-block community.
