Crews searching a US cemetery for victims of the 1921 Race Massacre found five more coffins, bringing to 20 the number of coffins found at a mass-grave feature there, city officials said.

After much of the excavation and analysis is completed this week at Oaklawn Cemetery in Tulsa, Oklahoma, city officials say a formal exhumation process is expected to start on Monday.
