Washington, June 25 (RHC)-- The U.S. Justice Department is expected to file hate crimes charges against Dylann Roof, the white supremacist arrested for last week’s massacre at a historic South Carolina church.

Federal investigators have reportedly honed in on the racist manifesto Roof posted on-line earlier this year.

In related news, Bible study resumed at the church Wednesday night, just one week after the shooting. This came as thousands of mourners gathered at the South Carolina state House to pay tribute to Rev. Clementa Pinckney, a state senator and the Emanuel AME Church pastor, who was among the nine victims. Pinckney’s body lay in state ahead of his funeral on Friday. Pinckney is the first African American since reconstruction to lie in honor in the state rotunda.
