The self-described white supremacist, who admitted to the killings during trial, could face the death penalty or life in prison. The jury agreed with the prosecution that the murders were racially motivated, according to multiple media outlets.

Roof opened fire at the historically black church in Charleston, South Carolina, on June 2015, shooting 77 bullets during a bible study. He was found guilty on all 33 counts, which included "federal hate crimes and obstruction of religion," the Associated Press reported.

The sentencing phase of the trial is scheduled for January.
