(KJRH/NBC News) -- The search for possible mass graves created after the 1921 Tulsa Race Massacre has resumed.
On Monday, a team conducted site preparations and began the initial soil removal at Oaklawn Cemetery, one of the three possible mass graves locations.
A team of city employees and researchers from the University of Oklahoma dug into a 16 x nine feet area on the west side of the cemetery. Researchers said they found some debris and a few artifacts on the first day.
In October 2019 the Oklahoma Archaeological Survey found an anomaly underground with a ground penetrating radar.
