It's been nearly 100 years since the Tulsa Massacre — where as many as 300 Black Tulsa residents were killed by mobs, police and members of the National Guard.

Tulsa officials said at least 12 coffins were discovered over four days of digging in the city-owned Oaklawn Cemetery. More tests need to be conducted to determine if remains are massacre victims.

The violence happened on May 31 and June 1 in 1921, when a white mob attacked Tulsa’s Black Wall Street, killing an estimated 300 people and wounding 800 more while robbing and burning businesses, homes and churches.
