 New this morning, the city of Tulsa resuming their search for mass graves for the 1921 race massacre. Last week, the city announced they used genetic testing to identify the first of the victims found there. C.L. Daniel was a World War I veteran killed in the race massacre. Today, the city will begin its fourth excavation at Oak Lawn Cemetery. The work is expected to involve enlargement of previous excavations and possibly the exhumation or re-exhumation of remains in the vicinity of Daniel's.
