 Forensic scientists in the U.S. state of Oklahoma have identified the first person found in a mass grave containing more than 100 victims of the 1921 Tulsa Race Massacre. The city's mayor said the remains of C.L. Daniel, a First World War Army veteran, were identified using DNA from descendants of his brothers. He died during a riot by a mob of white racists who killed about 300 black people over two days.
