The deadly 1921 rampage was a coordinated, military-style effort to destroy a prosperous Black neighborhood, a new report says.

The first-ever U.S. Justice Department review of the 1921 Tulsa Race Massacre concluded Friday that while federal prosecution may have been possible a century ago there is no longer an avenue to bring a criminal case more than 100 years after one of the worst racial attacks in U.

The Justice Department’s conclusion follows an investigation of the 1921 atrocity in Oklahoma in which up to 300 Black residents were killed.

Police arrested the man who was alleged to have assaulted the woman, according to the Justice Department report, which said that a local newspaper sensationalized the story, prompting a mob of white Tulsans to gather outside the courthouse and demand a lynching.

A new federal review finds the 1921 Tulsa Race Massacre was the result of systematic, racially motivated violence targeting Black residents of the city’s Greenwood District.
