A US Jury on Tuesday condemned self-described white supremacist Dylann Roof to death over the massacre of nine black worshippers in a South Carolina Church in June 2015 a crime that shocked the nation.

Roof, 22, was convicted last month of 33 federal charges including hate crimes resulting in death in connection with the shooting spree at the historic Emanuel African Methodist Episcopal Church in Downtown Charleston.

A bible study group at “Mother Emanuel,” which had welcomed roof, was just beginning its closing prayer when the self-avowed Nazi and Ku Klux Klan sympathizer opened fire, killing nine people ranging in age from 26 to 87.

Roof showed little reaction to the decision, delivered just hours after the 12-member jury retired to deliberate, though he occasionally seemed to be slightly smiling.

Federal Judge Richard Gergel will formally deliver roof’s sentence on Wednesday morning at the Charleston Courthouse. The verdict unanimously reached by the jury is binding.
